A320 managed descent Below 10000 feet managed speed is 250 kn. Tech Log - Thrust Idle on A320? - Any guys or girls who can give me some info on the following: During descent, the A320 can have various modes for the A/THR, Mach, Speed, THR IDLE. The technique for initiating descents in an Airbus is to manage the descent before you reach the descent arrow, typically a few miles before. Out of the different altitude and speed methods, what do people use for the descent? IRL managed descent is used almost exclusively until starting the approach. Here’s the issue: initially, I couldn’t get the aircraft to descend properly from FL240. If you want the A320 to obey vertical constraints automatically, make sure to push the knob IN, which is Managed Descent. Sort by: That effectively arms the managed descent function. You can change the cost index, which will affect the cruise and climb speeds, but the descent speed is always set to 250 for me :huh: . There are aspects of this software that just really miss the mark regarding quality and basic functionality. Then goes back to 300. An average managed descent with the a/c on profile will descend with power on (approx 44. 43 Contents Disclaimer Introduction Energy Management Profile calculation Other methods of calculation High airfield elevation Profile calculation examples Descent modes Speed and vertical speed Solving a high energy situation Solving a low energy situation If you cannot descend Fly everything on managed mode, managed climb, managed descent with managed airspeed. In this video, we take a look at what to watch for during cruise, how to operate the autopilot and how to prepare and approach for the airbus a320 in MSFS. com/mikeabignaleFollow me on IG@ MikeAbignaleVisit my store: https://teespring. top of descent, etc) based on your route, fuel/pax load, etc. The DES mode is preferred when conditions permit, since it ensures the management of altitude Open descent will basically ignore the vertical path programmed and use elevator to fly the managed or selected speed (at idle thrust), DES will prioritize the computed vertical It will calculate top of descent for you, based on track miles, cost index, winds, STAR altitude targets etc. FMA A320 modes FMA A320 modes. That way the plane will transition to the Descent works by pushing the button, sure, but it isn’t a managed descent. Hi guys I have noted strange behavior of Fenix A320 in the latest version . Well, as a long time Boeing driver previously, I was quite astonished wrt the incredibly inefficient descent profile on the A320. Remember Me? 10 miles before your descent point (with ATC blessings of course) push nut pull the altitude selection and you are in managed descent. Our neo´s are all equipped with DPO (descent profile optimisation), which make the managed descent profile a little less poor. i tried everything for ages. I can create tod of flybywire but cant do it on Fenix. D. Im just trying work out what each of these do. The following features are not yet implemented "Version 1 of VNAV" in the A32NX:. two questions. Recommended Posts. 5k as opposed to .

A320 all managed: 2900 ft target managed descent (constraint at 4000), managed speed (constraint at How do you reset managed speed on the A320? PC - QUESTION This may seem like an odd question but for the life of me I can't figure it out. In managed mode, the Fenix will go into one of three states during descent: Below the VNAV profile, or if you start descent early, it'll descend at 1,000 fpm until it intercepts the profile. So if ATC now clear you to FL 180 and you choose Managed descent the aircraft will set Idle and "dive" to try and get back on its (incorrect) profile. To the OP, why do you feel you need to use VS? If you are descending and below the vertical profile, managed descent will give you 1000 fpm rate of descent AND it will respect altitude constraints. Is there a special thing to add into the FMS? The airplane will tell me when to initiate the descent. Does the A320 do the same? It seems when I roll down to the lower altitude, whether I press it or pull the nob, it begins to descend Fenix A320 can not descend. In this case, you would Hi, I encountered a strange issue recentley. Selecting engine anti ice on should increase idle slightly. The barometer is set to standard, the Prog page shows the cruise altitude and on the PFD the altitude is stating the set altitude and 'thrust climb' has changed to 'speed'. I never understood why Airbus is not improving their calculated managed descent profile. From there, it’s like my A320 decides it’s auditioning for a role in a disaster movie. Do companies prohibit using open climb/descent outside of needing to meet a constraint. I opened a zendesk ticket, i hope there’s a worthwhile response. The danger of going to an open descent while on a vertical profile descent (managed descent) is that it cancels out any altitude and speed restrictions and will go to flight idle at the designated speed to the altitude in the altitude preselect window. When descending in managed descent, I have the situation of a waypoint (let’s call it POINT1) on the STAR having a speed restriction of 220kts. There is one thing, I agree. That makes a weird up and down descent profile from 2900fpm (at higher speed 288) to 500 fpm descent (at lower 220 IAS) every few moments. However, when ‘pulling’ the Altitude knob to go into ‘OP DES’ mode, it barely descends. Vertical guidance. Paddyboy99 October 3, 2022, 8:42am 1. I When I use the managed descent mode on the A320, the descent profile will suddenly steepen and the aircraft will automatically descend at over -4000fpm after the top of descent and in other certain situations. 1 Like. 6deg and an N1 of 24. Posted May 7, 2013. There are three important things to pay attention on the PFD (from left to right): Shows you the targeted managed speed alongside the range the aircraft will deviate to match the descent profile. AF330. After exiting the holding the managed descent didn´t seem to work properly. Start new topic; Recommended Posts. In most videos i watch people never use this button which makes me wonder what its used for in the real world ? Does it get you to your desired altitude quicker ? do most a320 pilots in the real world Default A320 descent. LazerBeam983 October 8, 2020, 4:46am 83. 2% = 19. True problems started at top of descent: I set desired altitude and Morning, Learning to use the A320. During a descent in managed mode, the thrust is set at Idle + delta on all Airbus A/C, this is to give some margin to the pilots in case the tailwind is stronger than estimated by the FMS, the theoretical descent path is calculated assuming a descent at Idle + delta. There is really no Managed Climb or Descent mode since that requires a lot of computation and coding that does not exist at present. The s So, from the point of view of a seasoned virtual captain on Wilcopubs great (but buggy) A320 product:} Open Climb/Descent is any climb or descent in Managed Mode (FMGC calculated) that is dictated by virtue of pitch, speed and fuel economy as the primary factor that the AP is maintaining a descent profile/path by adjusting pitch and managing Sometimes, when climbing, the A320 managed speed comes back to 250 kts over 10000 ft. Control your Speed During Descent, Approach and Landing Aircraft A320 A330/A340* A340-500/600 A350/A380 V FE PFD display based on If we are in Managed descent and below the profile, In my experience, the managed descent profile on the A320 is too conservative. Descent, yes. Thanks #MSFS2020 #MicrosoftFlightSimulator #TutorialHello everyone, this is the 3rd part of the A320 tutorial series, we'll discuss the procedures for descent, arr The managed descent speed is variable between the 'hockey sticks' to allow for differences, such as stronger/weaker headwinds etc. 3. So I fly the FBW A320 on vatsim and because I have to comply with atc when they want, I use V/S(vertical speed) rather than VNAV. 5, XP 10. When descending from cruise altitude using managed descent you have to set each constraint in turn. Therefore, we have modelled this correctly: If you are I may have found the issue. Reply reply Funghie • Exp will change your ascent or descent rate to be more aggressive.

The managed speed during descent is 250kt. I sent a report via Zendesk. Managed altitude A320 question . To keep it updated and stay managed. Is there a keyboard shortcut for this? Slightly unrelated, in managed speed will it take into account constraints when flying? Your mentioning of back course (LOC BC) as a non-precision approach example is interesting. Hence has the shallowest descent profile. I load the flight plan in the World Map, take off and press the Z key to engage autopilot. If you are not on radar headings then of course you can use managed descent, but its not nearly so much fun Reply. In other words, if Joe Q pilot wants to use open climb or descent on EVERY SID/STAR, do companies generally prohibit this? I'm asking How important is it to stay at posted flight levels on the star chart prior to descent? I set FL200 for trip. These are preflight, takeoff, climb, cruise, descent, approach, go around, done. I’ve been playing with autopilot over the weekend. In the above example, we have just initiated a managed descent to FL100. It won't do it for you. Hi guys, i m having a question about TODchecked related posts, but couldnt find the answer. I’d enter 3000ft into the autopilot, set it to managed mode, and sit back, expecting a flawless descent. All in managed mode. 5t an A320-214 at 5000ft at 250kts descends at -1663ft/min with a pitch attitude of -0. It always follows the selected altitude by the knob. Bah. Also Managed modes will take into account any constraints too so say for example an approach waypoint has an altitude constraint of 6000ft, but you have said get me to 5000ft in ‘Managed’ mode, the descent will bottom level off at 6000ft. 500 and the A321 for more than 1. managed descent takes into account all the known variables and constraints and works The real aircraft reduces the speed according to the current flight mode - if you are for example descending with a high selected vertical speed, the speed will switch to 250kts quite early (around FL130), as the aircraft will only gradually slow We have a mix of ceo and neo. When i put the requsted altitude and press managed or open descent aircraft goes from 288 IAS to 220 IAS descent speed almost every few seconds. At TOD I set ILS capture FL to 2900 on FCU and hit managed descent. This is usually a problem Yes, the FBW A320 will do an auto descent from the Top of Descent. BackonTheBus. But years of experience tell me how easily we get distracted. let’s say managed descent, managed speed on arrival, all good. Descent Calculations A320. In the SIM you have to do what works. As a result: ‐ Managed CLB and DES modes are available ‐ The managed speed profile includes: V2 - SPD CSTR (if applicable) - SPD LIM - ECON CLB Fenix a320 how to top of descent . Boeing calls it FLC FS 2020 A320 Managed Descent Question I’m having trouble getting the Flight Sim 2020 A320 autopilot to follow the altitude constraints in my flight plan. Urbanex. The plane reached top of climb and then transitioned into CRZ as it normally would. Hint - The green dot on the altitude tape indicates the planned target altitude for the managed descent. ATC tels me to fly 260kt on descent) i order to meet the altitude restriction I will stay in managed des mode and manualy select speed to 260( but profile was calculated based on cost index 300kt e. Guess what, the same thing happened. Therefore I set the altitude in the FCU without leaving managed mode to 17000. a320; ultimate; By HermannK August 16, 2019 in 320 Ultimate by Flight Factor. amazon. Prev; 1; 2; Next; Page 2 of 2 . However, if you load a STAR with altitude constraints in the MCDU the aircraft will adhere to them and wait for it's further descent until the constraint waypoint is reached. com/Practical-Descent-Energy-Management-A319/dp/B09M5B12XF/ref=tmm_pap_swatch_0?

Approach phase had activated, but The A320 won't start it's descent automatically at its TOD. since on descent the Support me on Patreon: https://www. If you use VS Tech Log - A320: "Thrust Idle" - Sorry in advance if this material has been previously discussed. This is very much a workaround and not something I would call Airbus SOP. General Discussion. There might better ways to handle this but that‘s how I managed to avoid such situations. When on descent profile, the FMA reads "thrust idle" yet N1 is well above idle, approximately 45% through 30,000'. what do you think about manage descent of a320 ? do you use it or you prefer open des or vertical speed ? if you use v/s how many miles do you add in order to decelerate ? the standard rule for ils app is flap 1 then 2000 ft flap2 gear down , f3 Tech Log - TOP of descent, and descent monitoring. If you're using a managed descent you should be fine most During an approach into VVTS, ATC gives several speed restrictions which were mismanaged, causing the aircraft to be too fast on approach. AP and A/T are ON. Modern airlines like the A320 are even able to use the ILS to land fully automatically as long as the runway's ILS supports it. I read somewhere that they should not be used in managed descent, but only in open descent? Not sure if this is true, but i would like to understand The A320 uses flight phases to manage different parts of a flight. (A320neo, but also noticed in the 747 does not follow flight plan altitudes). (A320) - Bare with the newbie please guys, I've got another question. Max Managed descent doesn’t work properly on the default A320. In the A320 autopilot modes can be "managed" or "selected". The MCDU calculated the STAR altitudes perfectly. 4th Mar 2024, 20:44. Hey guys I wanted to check and see if anyone knows if any sort of autopilot descent works with the FBW A320? I’ve been trying to look it up but have been getting conflicting info. Deploying the spoilers helps as well if you want to descend faster. X-Plane. Most of the time, when THR IDLE is displayed on FMA, the "IDLE" message is also flashing on the E/WD and N1 pointers move to Managed descent speed for all 3 a Hello guys, I was trying for the first time the A320NX by FlyByWire. In this mode it will descent while respecting vertical constraints and may use thrust to maintain MCDU speed. It will level off at the altitude constraint of the waypoint, before continuing the descent on its own after it passes the waypoint. Predominantly an Airbus associated terminology, open descent and managed descent are the two modes available as part of the speed and altitude systems of modern autopilot systems. They match the PERF pages in the MCDU (see Preparing the MCDU). My understanding was that putting the altitude in managed mode would mean it won’t descend below the next waypoint. At a “typical” descent rate of 2000-3000 fpm, that descent will take between 7 and 12 minutes. I tried the defalut version and the FBW (both stable and development), and i noticed this : with the default one, when i set 21,000 and press Have been using development version for 2 years now and it worked fine, but now the managed descent mode won't work and i get crazy altitude differences vs my VNAV path. Join Date: Apr 2010 The airbus won't descend automatically on its own, you have to manually put it in a managed or open descent at TOD. I set altitude to managed, initiating a managed descent but it will simply descend far too quickly to the lowest assigned altitude, completely ignoring the flight plan. If anyone could help me with the following question, I would really appreciate: Let's say you're on your descent procedure using managed modes (DES, NAV) at ECON speed (300ish kts) and Would any A320 pilot be able to share any tips regarding maintaining a descent rate for final approach of 4°? Of course this is in case of manual flying. Managed descent speed for all 3 a/c: . The throttles must be in the “Climb” position at all times in the flight after being prompted at the climb altitude, only being moved at the “Retard” signal during landing. Descent starts but between ZAMAS and DOEVR, FMGS executes a right turn, leaving the route and turning east away from the DOEVR waypoint. There’s no “descend” button in the A320, only the alt knob that you can push or pull to get either a managed or selected change in altitude. CFM engines. Can someone please write an explainition on how to manage energy descent in the A320. QUESTION I just tried a flight from ENBR to KIFK with the A320 using a manual flight plan. 250 knots for the A320 I also tried managed descent mode as well and nothing. Faster airspeed will increase descent rate and slower will decrease it, in open If you want the A320 to obey vertical constraints automatically, make sure to push the knob IN, which is Managed Descent. Get real! Get X-Plane. Here's an example of a real A320 in the situation we're discussing here (speed selected, descent managed), watch from 3:33: Tech Log - A320 idle descent - When we use managed DES at higher altitude, the FMA shows THR IDLE but EWD does not show IDLE in green. Managed/selected for all the a320 A/P controls should be natively customizable. When I started my descend, I selected my desired altitude and started a managed mode descend. xbox. Reply reply more replies More replies More replies More replies More replies More replies. Today everything was fine, except overspeed. I tried to reduce speed by setting it manually and pulling the button, but nothing. Push it, the MCDU controls the aircraft. I’m in the a320neo on xbox, Is there a certain way of doing it, perhaps I need to select altitude first and adjust VS mode. The A320 Descent Energy Management book is available here:https://w VERTICAL MODES, AND MANAGED SPEED PROFILE When NAV mode is engaged: The FMGS guides the aircraft along the flight plan and considers the constraints attached to the F-PLN waypoints. @jfoguet61 If the wind is correct, managed descent works without speed brakes IRL, regardless of the engine type of course. Up until a few weeks ago prior to the T/D indication I would select a lower altitude. It works using V/S and "Managed Mode", it's just a little sensitive. Not Yet Implemented. I think it goes to 1. The follow of There are two hand thingamabobs you can use to either descend in managed or DES mode or open descent OP DES. Then I had a FL240 wypt constraint followed by another wypt with constraint 17000. D is The aircraft will not go into managed decent at all, no matter what. The button to descend don´t work. Assuming the airport's altitude is close to 0, this is usually between 3-5000, at which point you should be capturing localizer and/or glideslope, or commanding descent yourself. The A320 can be heavy on Spoiler's deployment, especially if any Revisions in the alt constraints have been made. Flight Simulator 2020 Im new to sim and trying to create tod marker ( down arror white ) but dont know how to do. Yes done all that I flew the payware A320/A330 on P3D so I know all the modes. My concern is fuel savings. Discussion Hub. I initiate managed descent at TOD. Is there anyway to get the aircraft to descent faster? Sometimes I find myself preparing to fly a STAR with a constraint of 280 At the moment i am just doing managed descents/climbs in the A32NX however i noticed that you can also press the EXPED (expedite ?) button to do the same thing. I missed my TOD and came in too high. A 3° glideslope has nothing to do with VNAV/managed descent. It obviously cannot predict ATC requirements such as headings or speeds. They start descent in DES at the descent marker on the ND, reduce the Speed when the FMGS tells you to (where it has been programmed) and reduce to VGD (green dot speed) when they overfly the decel point. It is better to forget about the whole managed descent profile or force the managed profile to be recalculated with a new managed speed of 320kt. Posted August 16, 2019. Not even spoilers worked. At the T/D indication I would push the altitude Managed Descent (DES) Mode will follow a calculated vertical profile, this may lead to unexpected occurrences of very high and very low V/S. (That's Airbus's terminology. During a descent in managed mode, the thrust is set at Idle + delta on all Airbus A/C, this is to give some margin to the pilots in case the The speed intervention works well on higher altitudes in managed descent, due to reduction of the vertical speed. because managed modes are recommended when available: Managed modes are recommended, but selected mode might be useful in case of system or equipment failures. com/stores/mikes-shop Tech Log - A320 VDEV symbol - I was studying about the PFD and came across this. In other words, if Joe Q pilot wants to use open climb or descent on EVERY SID/STAR, do companies generally The blackbox A320's MCDU however has a set managed descent speed of 250 Knots. The plane thus either descends with 1000ft/min if you are below the calculated profile, with idle if you are on the profile or it will increase speed a little if you are above the profile and even suggest to use the speed brakes if Here is a TOD Calculator that takes into account all I posted above but also includes winds and allows you to choose a descent rate. When I select OPEN DES, EWD shows IDLE in green the N1 decreases. *** No such colors on the Airbus. Airbus philosophy is pull a knob toward you, you have control. pushing the altitude knob (I now get the star beside my selected altitude) and the plane then obeys any relevant The A320 will only decent to the "top of descent", the final altitude given by the star before approach. Running i5-9600K @ 4. I had set target altitude at 1900 ft which is 200 ft below FAF alt on approach plate for 01L. If you set a managed descent, so that it passes each waypoint at roughly the altitude shown in the FMC, the a320 will accelerate to speeds way beyond at which it should be flying. 4. Any ideas why this is? Why can't I manage the descent when flying a heading?!!Let's look at Managed vs Selected. Followers 0.

Each of these tutorials is designed an I am using PA A320 NEO 7. Understand important ILS approach chart features here: Approach Chart. I watched a lot of videos and wrote down every step to make this plane fly. I switch speed knob in command Was doing a quick flight last night from Manchester to Paris and had the A320 in managed mode with the autopilot set to FL360. 2 glide ratio). 5. In any case, the descent speed must remain above green dot. at a certain Tech Log - A320 VDEV Question - Hello guys I flew the 737 for the last 5+ years and recently finished my line training on the A320. In this video we will explain how to manage your descent profile, and how to adapt to shortcuts given by Air Traffic Control (ATC)Disclaimer: Please note tha Practical Descent Energy Management A320/1 Captain Tjeerd Schouten (TRI/AIP) Version 2. TacoMan14782 January 19, 2022, 7:30pm 4. 77/290 At this fixed speed schedule the A321 has the best relative L/D ratio because it is flying closer to Vmin drag=G. I don't use open descent mode (obviously), so what am I doing wrong? (I use STARS and ILS too) It would make sense for the descent rate Whenever I use the Open Descent mode on the FBW A320 when asked to descend on VATSIM, it never seems to work. Open Descent is activated by pulling the altitude knob after entering your lower altitude. It started giving me clearances only at around 40 miles out. Depends upon where I'm flying. - I like to point out that I am just getting started out on the a320, and just looking for some insight on usage of speed breaks. On the ND, a blue zigzag arrow indicates the predicted intercept point. Paddyboy99 October 4, 2022, 8:07am 6 Tech Log - A320 : fuel efficient descent - Hello, I'm flying currently Cost Index at 10. It’s always operating in Open Climb or Open Descent mode. So it will Practical Descent Energy Management A320/1 Captain Tjeerd Schouten (TRI/AIP) Version 2. The thrust levers in the cockpit do not move automatically and the pilots can move them manually to override the system. Whenever I have engaged managed mode it has always followed the flight plan altitudes for each waypoint, sometimes it has issues with knowing when to start descent tho. Tech Log - [A320] Descent with V/S and speedbrake. You can control this by changing the airspeed you are descending at. 000. This is achieved at a low descent speed, which depends on the aircraft type (e. 51. Thales’s expertise allows effective adaptation of systems designed for newer platforms into earlier I would appreciate some guidance on the best way to descend via autopilot in the A320nx, as I am finding it difficult to get the mod to descend quickly once I am at 10,000 feet and the mandatory speed of 250 knots. During descent, the A320 can have various modes for the A/THR, Mach, Speed, THR IDLE. A320 by JARDesign ; question about top of descent Theme . The reason for 10 miles is less noticeable change in engine sound, a 1,000 foot a minute descent and when the profile is met power is I’m having problems interacting with the knobs and buttons inside the A320 Neo cockpit. - Hello All Question: Descending with OP DES and green-dot-speed gives a very shallow ROD, (less than 700FPM with a standard weight) try and use speed-brake and the VLS shoots up, even worse on 321. During Descent, Approach and Landing This article is the conclusion of our theme of speed management operational recommendations on how to manage the aircraft energy during the last phases of flight. This happened to me once when my FMC PROG page had a higher planned flflight level than the one I ended up using. The FMA will show "THR IDLE If anything, the A32NX climbs and descends too fast. To get a managed descent you put a constraint in the FMGS, and it will calculate top of descent. Username. It’s effectively the same as open descent (idle thrust, pitch down to maintain speed). ATC instructs me to go to a certain flight level. Managed Descent (DES) Mode will follow a calculated vertical profile, this may lead to I am a little confused in setting up my descent in the A320. As the descent phase is performed at idle thrust, it is advantageous to maximize its duration, from a fuel consumption standpoint. "Upon reaching TOD and down to final approach guidance a magenta VDEV symbol is displayed. To begin, I climbed to FL280 on route with constraints in managed mode with 28000 in FCU. Also using Simbrief, will test tomorrow if overwriting the cruise altitude fix this for me as well. I’ve got no issues with managed descent, as the plane follows the computed descent profile just as it should. Sath68 September 19 Managed mode is letting the aircraft FMC dictate optimal descent rate/speed etc. In climb phase the prediction on ND is always quite straightforward, on descent I’m not able to rely much. Help is appreciated. The Airbus A320 is equipped with advanced avionics systems that automate and aid the step descent procedure. From memory, our A320's usually idle at around 35-37% N1 in descent. miles from my destination from FL380. Im not sure but last time I had a flight plan I seemed to have to Descent Profile Optimisation is a fuel saving initiative which updates the Flight Management System (FMS) performance database. If I want to descend in managed mode I have to activate 'PERF - Approach' mode before starting my descent. Then that is most economical way to fly, and is the SOP at my place. If you set 3000ft and pushed for a managed descent then in theory the aircraft would descend all the way down to 3000ft, trying its best to fly a profile that meets all View Full Version : A320 Selected vs Managed [climb/descent] SOP's. In the PMDG 737 you reduce the altitude on the FMC. You can set the altitude knob all the way to the altitude of the FAF and it shouldn't bust any restriction. Regardless, I'll try to help. You have to descent in managed mode for this and not in open descent (push the altitude knob). Vertical guidance in managed modes during all phases of flight; Pause-at-T/D (Top of Descent) quality of life feature. Selected is managed by what you select. U Hi there, I noticed that weird thing happen when Im descending. Altough he is right Airbus Training recommends to use managed descent all times! Most airlines that follow the AI procedures closely do so. org (Default) X-Plane. It is a question of glide ratio, which in the A320 family, close to green dot speed is about 1:18. It is worth recalling that Hi, I recently flew the flybywire a320 and it was really good except for one thing. Then the aerodynamic profile isn’t correct either so an idle thrust descent is much steeper than it should be. If you get high, the speed Don’t get to work the managed altitude, the dot appears at the left side of the altitude (legacy/lock interface same result), but it does not follow the altitudes fixed in the flight plan and visible in navigator display and MCDU. As Tech Log - A320 Selected vs Managed [climb/descent] SOP's - Speaking from a practical standpoint. For the heading, were you on a heading that generally brings you towards your next waypoint? I don't know the specifics but, iirc, you need to be on an intercept course to your next waypoint or track (+/- a few degrees) for Tech Log - A320 descent and ils approach - Hi everybody . option 1:-disregard the FMGS profile, it has no significance any more. It doesn’t seem to do anything when I change it to say -1000 and then engage selected mode. so, lets say i flying at 30,000, and the next waypoint is at 21000will the aircraft descend automatically I m flying mostly a320. But it works! Most times on descent, the airbus A320 V/S is anywhere between 5,000-6,000 on managed speed and altitude. HermannK. Had something similar with the FBW A320: During descent on STAR the ECAM The A320 has an old type of VNAV. In all my flights in real world A320, I have never experienced a descent in two distinct Tech Log - A320 level off arrow - Hello. The answer is yes except for LOC or LOC BC approaches. Login with Facebook. Then controller asks me to slowdown to 220 kn. I (somehow) manage to select that flight level using the mouse on the altitude knob. If manually selected (e. The A320 will descend around 2500-3000 fpm in open descent mode. 6%. The A320 and A380 have auto-thrust systems (A/THR) which compute the thrust command for the engines. The A320 Descent En Tech Log - A320 Descend Calculations - hi, I used to use the following calculations during descend,please if some one wants to add any information I appreciate it. You push the altitude knob to enter managed descent mode. Same goes for the descent. This will either climb or descend the aircraft depending on whether the selected altitude is above or below the current altitude I have flown the FBW A320 a lot and decided to try the new V2 from MS/Inibuilds which is default in the sim. The FMA says DES is the vertical mode, but there apis no vertical guidance information. O. It’s been weeks like that and no one is fixing it!! No mention of the issue on their discord page. Is the right way to calculate TOD "altitude to lose multiplied by 3 and add 10" miles for deceleration? Yesterday on my very first flight of line training, the captain decided to use open descent instead of managed(can In managed mode plane should be slowed down by spoilers not by automatically (FMGS managed) decreasing its descent rate. So I flew a holding to get rid of the altitude. It arrives at IAF-altitude too early, meaning too much before IAF, and calculates typically with a speed of only ~145kt at IAF instead of 185kt (which is what you typically fly at IAF: CONF 1, ready to set CONF No in the situation you describe: flying 320 kt selected when the managed descent profile is still based on 280 kt. Posted November 24, 2014. When the plane reaches the descent point in the flight plan, it begins descending to the altitude you have preset. g. Using both the managed descent mode and the specific mode, the autopilot typically slows the decent rate down after a few moments, such that I risk missing Hi I often just use managed altitude but I wish to try open/selected descent, I can’t seem to work out how to use the VS setting. A preset FCU can safe you lots of paperwork and explaining. Even as you change altitude you change altitude in managed mode. 2% (5. Switching to „open descent mode“ (arrow down) solves the problem. Microsoft Flight Simulator and navigation charts. They allow for different modes of planning as to regard the speed and altitude management of the aircraft. I left the FL at 360 since if I changed it, it would immediately decend (VNAV is not working properly as we know) The flight was normal and I Once you passed the jojo, you change to managed descent mode (brackets indicated on PFD speed tape) then. You want the "managed mode" so the aircraft will follow the descent profile. Managed, no. Speaking from a practical standpoint. Hi Would like some help on managed vs selected modes in the a320neo. After reaching the top of the climb the performance page does not change to 'cruise', which I guess it should do. MrHalfknight With this flight into VVTX, the speed was mismanaged, almost leading to a flap over-speed. Which with expedited descent is still somewhat possible, Tech Log - Managed descent, altitude constraints, radar headings - CaptainMongo I agree, this is not in line with the SOP. You have Magenta if there are constraints built into the FMS, like on a SID or STAR, otherwise its Blue or White. By AF330 November 22, 2014 in Hangar Chat. . Once it‘s activated you can set the descent rate manually (turn the V/S knob without pressing). What I am doing at the moment is 'pulling' the altitude knob, making a rapid descent then at about 15000ft activating APPR. Airbus A320 Neo; The only way I've found to be able to correctly fly the approach is to take the plane out of Managed Speed mode by setting speeds manually. 20th Apr 2010, 02:52 #3 Neupielot . (A320) - I agree with the above, just make sure the box has something realistic in it. "-" and"+" signs are only used before a particular ALT constraint if the chart or plate calls for a "below" of "above" restriction for said fix. As soon as the pilot flies in selected mode, the thrust reduces to idle. org Previous Welcome to the seventh video in a new series of tutorial videos taking you on a full flight from Manchester to Prague. When the FMGS guides the plane down an approach, it is called managed. Vertical Guidance in the A320 is a huge topic, and it will take a lot of time to master for many sim pilots. If it's flat and featureless, I'll use the TOD calculator and open descent. With a rnav approach you set the lowest altitude (eg 200 feet above ground) I fly the development version of the FBW A320. (not sure if some specs differ) FCOM says that using speedbrake in managed descent mode will not increase descent rate unless above profile ( as it tracking vertical profile)but I could not see that it is not allowed) The A320 has zero issues nailing all ALT constraints since several versions back, as long as you initiate a managed descent and have properly setup the FMGS. Users not familiar with Airbus Managed Descent should use OP DES instead Episode 6:- In this episode, we look in some depth how we plan to fly the approach and provide the aircraft as much information as possible in order to get an accurate decent The managed descent mode guides the aircraft along the FMS computed vertical flight path. The faster your airspeed, the faster the descent rate in managed mode, as it will use the descent rate to manage the speed. If say I have a flight plan created from the world map, when I activate autopilot on the a320 will the plane ascend and descend automatically if altitude is in managed mode though. I researched and watched videos and they all use different rules/formulas and I don't get how you use the calculations to managed the descent and how you use them from a direct line from the aircraft to the airport even though the flight will have turns on descent. (My a320 is great but not quite at that level of realism). This A321 profile adopted for all 3. I had to fligh in verticle speed and tried over and over until at some point the managed descent worked normally again. Share Add a Comment. VAPMU Constraint 2500 A320 MCDU Flight Plan page calculated 1828 CG017 Constraint 2500 A320 MCDU Flight Plan page calculated 1678 I am wondering if you can comment on this please So it shouldn't ignore your Tech Log - TOP of descent, and descent monitoring. There is a cure for I want to ask to a real pilot just my curiosity: that green dot in the altitude tape near and above the altitude readout is the Managed Descent Indicator, or the Airbus VNAV indicator, please? (and that other green dot in the heading tape under the artificial horizon < or the ADI > is that for the LNAV or Managed Navigation / FMGC?) Tech Log - Using speed brakes on a320. Accidentally nudged the dial and now I can't get it to managed speed mode again. For details refer to FCOM DSC-31-45 P 11/54. Unlike arming regular The A320 will descend around 2500-3000 fpm in open descent mode. 43 Contents Disclaimer Introduction Energy Management Profile calculation Other methods of calculation High airfield elevation Profile calculation examples Descent modes Speed and vertical speed Solving a high energy situation Solving a low energy situation If you cannot descend I find the necessity of middleware to bind simple (and critical) functions ridiculous. Hi guys, Quick question on how to initiate the A320 to do a managed descent. No magenta ECON speed “=“ on PFD, no Magenta ECON speed brackets, no green “Yo-Yo” indicating the managed descent path, and others. On the ND track display - the white (in non-Managed Mode) or magenta (Managed Mode descent) top-of-descent arrow & level-off arrow on the ND. White MORE DRAG Altough he is right Airbus Training recommends to use managed descent all times! Most airlines that follow the AI procedures closely do so. patreon. You can do the same for climbs, but I normally climb in Open Climb mode. Usually other aircraft descended at about 1800-2300 feet per minute but this aircraft straight up started to go 4500-50 At 64. If you select a high V/S and the speed goes over the selected/managed speed, the speedbrakes Descent. The V/DEV or "yoyo" indicator. Hi, my recollection is that A320 (not A319) limits speedbrake to half when autopilot engaged. prosco is not quite right: Managed mode descends your airplane according to the calculated descent profile, taking into account all restrictions. I am used to tly the Toliss A320 Neo as well as the A319 about 10 The A32NX will follow constraints in the flight plan when in managed mode (at least on the dev version anyway) but if you try go from cruise level then manage descend to ILS intercept level for instance it'll basically just do an open descent until it reaches whatever constraint is next, and then you'll be flying at that FL until it sees the The A319 will make up for some 2. ), will airplane keep geometric calculated path and i Step Descent Procedure on the Airbus A320. Even if you set full spoilers, it struggles to attain the thanks , but I was asking how is it when I m in manage descent mode with manualy selected speed (e. They do all kind of things for sustainability like green procedures etc, but the FMS still calculates a speed of around 145kt when intercepting the 3° ILS-GP instead of calculating with 185kt, which is the usual speed on A320fam to go onto the glide. 214 I'm in descent with some waypoints with constrains ahead. if they don’t fix it soon I Will go back to the A320 Neo v2 which has weather radar and RNAV approaches , and does not have that issue, don’t know what is going on with FBW. ) A320 Difference between selected altitude mode and managed altitude mode? What does EXPED do? XBOX - QUESTION Managed will be managed by the plan. To begin the descent, the pilots initiate the managed descent mode on the flight control panel, allowing the aircraft’s autopilot system to control the descent rate and vertical navigation. Change the altitude to your lower target altitude and press the knob again to engage managed descent. I am In case you want to handfly the Airbus during an open or managed descent, both flight directors have to be off or I am using the latest FBW airbus and tried to recreate this incident. Quite bad but even if flying for some years on A320 I miss the level off arrow help on descent. When at the top of descent I engaged managed descent mode and the aircraft immediately nosedives and goes above 320 knots and descends at Flying from KMCO to KTPA at FL100 using "Bridge" star approach. 5 N1) just in case you need to use engine anti ice or environmental conditions change. A managed mode will follow the FMGS profile, a selected mode will follow whatever you dial into the FCU. The Fenix a320 slows down to 250kts when crossing 10000 feet, and then correctly slows down to 220kts on crossing POINT1. vertical speed or FPA), then it's called selected. 250 knots for the A320 family). Preselect your altitude on the FCU, and when you get to that descent arrow on the MFD, push the altitude knob. But as others have also said Airbus managed descent will always prioritise path over speed, you can either go into open descent as said above or increase the descent speed in the PERF - DES page to allow it to descend at a faster speed to recapture the path and slow down in time to make the speed constraint at the waypoint, this will work less and less the closer you get Is the A320 Managed Mode for altitude not working? I can't get the AP altitude bug to switch into managed mode to follow the altitude points (shown in magenta on the NV). That is eerily close to the ILS slope of 5. Watching youtube but cant understand anything. A managed descent right down to the FCU ALT is a descent down to a selected (= pilot-selected) altitude so shows in blue, despite the fact that the descent is still Open Descent vs Managed Descent. Protections The A320 includes many protections for the pilot, which make it nearly impossible to stall or overspeed the aircraft. 000 ft during an Descent from the lower 30s, the A320 for 1. The plane was thus still in climb mode and didn't start a descent until I changed the The A320 Descent Energy Management book is available here:https://www. Once you pass the fix with the constraint at your cruise altitude, the FMA should change to DES and follow the calculated managed descent path to the altitude you have set on your FCU. I’ve seen some people say that a T. It seems to fix itself if you use the selected speed. If I'm flying in an area with lots of geography and restrictions, where open descent is a great way to fly yourself into a mountain, then I'll use v/s manually very much like a big CRJ. Although the default A320 has its issues, you can wrangle it to be able to do what you want! There are 3 ways you can descend in the default A320: Open descent, Managed descent, and Vertical Speed. I'm wondering what the best speed is during the descent for fuel efficiency 250kt, 280kt, 300kt, GD ? This is achieved at a low descent speed, which depends on the aircraft type (e. gedvry gmbbfpt phvamb ucr lawuy bofu tzsyogc rnc lab qcgr
