The mysterious crash with the A320
EHM-2173 Bastiaan:
I was flying from Stockholm Arlanda to Klagenfurt with an Airbus 320. I minimalized FS and started to work on my homework. Every now and then I looked in case I got an instruction from the ATC or something. But the last time I looked on this flight I saw something really strange. I was lucky enough to witness my aircraft going spinning in a vertical dive in to the sea just south of Stockholm with all kinds of alarms going off and thing...
I used my autopilot heading/altitude and speed and at the moment I was climbing to FL350.
Does anyone have a explanation for this mysterious crash south of Stockholm. It was my last flight before my rank allows me to fly the A380's and 747's so this is kind of annoying...
EHM-1612 Paolo:
That's scary :| The only thing I can think of is wind changes, it used to happen to me when I fly online and wind speed and direction rapidily change...I corrected it with FSUIPC, but I am not sure if your crash is a result of winds... :[
EHM-1651 Christian:
It can be the sudden change in wind speed and direction that FS makes between the different flightlevels, which can cause either an overspeed or in your case most likely a stall that results in a spin.
It can also be a stall caused by setting a to high rate of climb causing the Autopilot to raise the angle of atttack*(AOA) to such levels that you loose all to much speed, in a real life A320 this will be impossible due to the Fly By Wire system and FADEC(Full authority digital engine control) system. If this happens the Alpha-floor system will engage and the engine will be set to max power (TO/GA setting on Airbus) to prevent the aircraft to stall and it will also reduce the AOA to a normal level.
EHM-2173 Bastiaan:
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..

I had "something similar" on my last route to Chicago onboard the PMDG-747. As I was approaching the Canadian coasts, because of scenery changes, the Flight Level changed a lot and quite frequently. Then also the wind changed from minute to minute which (I believe) caused to somehow kill the IAS hold system...the "VNAV SPD" sign disappeared from the PFD.
I was watching TV next to the PC... the plane was in VNAV mode with A/T ON since hours... and suddenly it turned off and could not hold the speed, which caused a STALL situation. I realized it only from the sound effect came from the headphones resting on my desk.
I fought with the Autopilot, while after some 3 minutes with scaring passengers behind, I could somehow arm again the Autothrottle, and I could continue the flight.
Although it was not the A320, but I am sure wind changes + scenery level changes caused to kick off the Autothrottle, and if I was not cautious enough, it would fallen down like yours mate.
