Was doing a quick flight last night from Manchester to Paris and had the A320 in managed mode with the autopilot set to FL360. The plane reached top of climb and then transitioned into CRZ as it normally would. Furthermore, you would initiate that descent at 3 times your altitude to lose. V LS is always greater or equal to the Minimum Control Speed at Landing (V MCL). Speed target may either be selected or managed. You have to descent in managed mode for this and not in open descent (push the altitude knob). However, it might be convenient to switch to ALL or BLW. Oct 14, 2023 · Hi guys I have noted strange behavior of Fenix A320 in the latest version . Users not familiar with Airbus Managed Descent should use OP DES instead as it provides a linear descent most users would expect. Benefits: Enables a longer cruise level; Reduces deceleration Then you can enter the altitude. Hi All In aviation, the rule of three or “3:1 rule of descent” is that 3 nautical miles (5. I reasserted my cruise altitude. I don’t like the airplane slowing down way too early (often happens with managed speed and managed descent) and I don’t like descending with a constant high Mach number (managed descent with a high cost index results in very high descent rates at the TOD). AbuzzPluto8091 November 10, 2022, 1:06pm 15. These are preflight, takeoff, climb, cruise, descent, approach, go around, done. Would result in a very steep climb. Using CI is acceptable, but in lieu of specified speeds on an arrival procedure, we teach that 300 KIAS is generally acceptable to ATC for maintaining traffic separation Feb 24, 2021 · In theory (and if you were to ask Airbus) the automated modes work flawlessly. If the aircraft is still changing speed (slowing down or speeding up) it will do so while maintaining the same altitude. The FMA says DES is the vertical mode, but there apis no vertical guidance information. The target speed/mach is maintained by the AP/FD system by adjusting the pitch with the elevator, whereas thrust is maintained either by the Autothrust system, or manually by the flight crew. May 8, 2015 · Once you passed the jojo, you change to managed descent mode (brackets indicated on PFD speed tape) then. The progress we have made on the LNAV and flight plan management system has enabled us to ramp up development of the aircraft’s vertical navigation (VNAV) system. An A320 can fly a fully managed (lat/vert) NPA if it is VOR, VOR/DME, RNAV, or NDB (given that the approach is correctly intercepted and GPS primary is available or the navigational accuracy is good). Jul 23, 2022 · During descent, you may get vectors to final. The descent rate is calculated automatically by the aircraft based on the Cost Index (which I always set to 100), Block Fuel, and ZFW/ZFWCG. Then controller asks me to slowdown to 220 kn. The system also considers speed constraints if the target speed is managed. Aug 16, 2019 · The technique for initiating descents in an Airbus is to manage the descent before you reach the descent arrow, typically a few miles before. Managed mode is an autopilot function that “manages” your entire flight phases from take off, climb, cruise, descent, and approach based on the inputs that you entered in the MCDU computer. To answer your question, you need to left click the altitude selector knob in order for the Jan 4, 2021 · You have to manage climb with v/s (same as IRL) but descent it will do for you. I’m running 0. Also it is probably possible to set a range (FL095-FL120) In the same page, you can set a speed associated with particular waypoint.

If the descent phase is active: Nov 23, 2022 · 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. I have to extend spoiler to decrease speed and after, extend slats. May 29, 2012 · The reason for the difference of speed brake extension A320/21 is during testing it was found that during an emergency descent with max speedbrake on the A320 that the resulting pitch up moment exceeded the autopilot authority to correct it resulting in it going into a protection area (guessing alpha prot) and the autopilot disconnected. 6 km) of travel should be allowed for every 1,000 feet (300 m) of descent.

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. Protections The A320 includes many protections for the pilot, which make it nearly impossible to stall or overspeed the aircraft. DOWNLOAD PDF. com/mikeabignaleFollow me on IG@ MikeAbignaleVisit my store: https://teespring. 78/300 in the Descent Perf page. Descent Profile Optimisation (DPO) is a fuel saving initiative which updates the Flight Management System (FMS) performance database by reducing margins in descent models. I needed to modify it because it did not correctly string together the STAR so, I had to manually update.

For example, if you're holding 2 degrees nose up to maintain level flight at 14,000 MSL at 180 KTAS, you would drop to -1 degree (1 degree nose low) on the ADI and expect to see 900 ft/min on the VSI. is it supposed to be like this? i am wondering cause i have a "descend" page in my flight computer with a managed speed set. Nov 7, 2023 · Managed descent mode (DES) in the hold will limit the descent rate to a maximum of - 1000 ft/min for traffic separation purposes. The crossover altitude may be different when using Managed Speed or Selected Speed as the system can use In the MCDU, set a hard altitude constraint, in this case at BUNTS, at 8000. It is important to understand these flight phases as they have an impact on planning a flight as well as on the lateral and vertical guidance of the aircraft. Descent, yes.
