The mysterious crash with the A320

<< < (2/3) > >>

EHM-1465 Dominic:
Yep,

I think it's likely that if you set the autopilot to climb to cruise altitude and don't keep reducing the vertical speed as you climb, your airspeed will decrease until the plane stalls, more so when the aircraft is heavier...

This is the reason for step climbs to reach cruise alt as your weight decreases...

EHM-1838 Andrew:
Hello
May i suggest you leave your homework until you have safely reached your cruising altitude.;)
It definitely sounds like a stall,which accounts for the stall warning sound plus the overspeed warning sound(as you plummet earthwoods.
cheers Andy

EHM-0654 Murray:
Ah... this would be the fleet A320 (I think you said...)

One cause of this problem will be the lack of an FMC system... If you had any sort of flight management computer driving the A/P, it'd handle the reduction in climb rate as you progress to cruise in order to maintain airspeed (like Project Magenta does for me when I'm flying any of the fleet Boeings...) I do know that the newer 737's (the NGs) can climb straight to cruise without stepping as long as the FMC does all the work, maintaining climb airspeed and adjusting the V/S as required, and I'd be very surprised if the A320 can't do something similar.

As it is, have a see if you can find a flight envelope profile for the A320; that'll tell you the various V/S's through the climb to keep you close to your MCP speed.

And sorry for all the Boeing terms in this post, I don't know 'buses :)

EHM-1507 Manuel:
Sometimes I made similar experiences while flying with "real weather" option activated in  FS9.
It helped to deactivate and activate it again as soon as you have a stable climb again.

I think the last explanation about the stall thing comes close to the truth. After al, the stall alarm was going..together with the overspeed alarm what makes it kind of odd..

The when the stall becomes a deep stall which it often do when getting a to high AOA, causes you to get in a spin causing the speed to get really high.

As far as I know the A320 is capable to go straight into optimum cruise level from a MTOW take-off, ofcourse the last part of the climb is really slow.
