I flew the PSS A330-300 RR from ESSA to OIII (EHM-6360), when after about 3.5 hours the plain suddenly dropped out of the sky. I flew @ FL400 M0.82 there was ennough fuel on board and I really don't know what went wrong, can anybody please tell me what the problem was?
-
mabey there was an engine failure, or if online, you might have pressed a certain key that made it crash?:% if not, beats me...
-
Your fuel setting ? This plane is realistic, after some time you have to change the fuel pumps layout. But it's not sure it has been the problem.
-
I don't think it was an engine faillure because they were still running when I controled the plane again at about 4000ft ,but thanks guys.

Was it starting to do nose-dives a violent pitch changes?
Or was it just having trouble staying up generally?
-
suddenly the airspeed was gone, maybe due to the realweather with updates, but no there were no nose dives, the aircraft tried to stay up so it stalled.
-
In that case it could be that as you were at FL400, which is around the service ceiling, and if you had 'plenty of fuel' you may have been too heavy to fly at that level with that fuel and the weather at the time.
- Just a guess :|

Ben,
Sorry for the late reply:$, work,work,work!
No, I don't think that's the problem, because the FMC tells you what's the best altitude to fly and with plenty of fuel I ment it could'nt be out of fuel. but thanks for your response:>
-
Well I'm all out of ideas then ;)
Just hope it doesn't happen again!

Can't speak for the A330 FMC, but the 737NG FMC, when it doesn't get en-route winds and cruise temp entered, has a nasty knack of giving a TRIP CRZ that effectively is the service ceiling for the take-off weight, and "guessing" the fuel usage.
My 737NG FMC book recommends entering full cruise wind forecasts (RTE DATA from LEGS, LSK6R for the 737NG/Smiths FMC) if time permits...

Hoi broertje!
Let me kick against another "holy house": knowing the airbusses (not first hand, but read a lot) they are equiped with a system/software which protects the flight-envelope (so to say). They refer to it as the three laws (normal, alternate and direct law). To the point, am under the impression that, although PSS did an absolutely marvelous job on their airbus series, somehow they did miss the boat a bit when it came to simulating the three laws.
Ever heard about because of the fly-by-wire system it is practically impossible to stall the actual aircraft (let alone make it drop from the sky)? Well, in FS2004 it aint that difficult at all. Have had lots of problems making dead-normal approaches where, while being still at Vref+15 or something like that, the plane would just suddenly loose its airspeed (and then even full-throttle doesnt do anything) plummet to the ground. Unfortunately did not have 36000 feet altitude to keep the plane flying...
Still, as said, the airbusses are awesome machines!
Perhaps it's a family thing!? ;D

He Bolle ik hier?
Comming back at this topic onesmore,I think it happened because of a sudden wind shift, from a strong headwind to a strong tailwind. The same thing happened a few days ago again, but now I checked the flightanalyses wich showed an airspeed of 256Kn the next moment it was 124Kn. I dont think this is PSS's mistake but maybe one by MS? Anyway I'll have to find out how to make smooth wind changes.:o

Smooth winds is on the Winds tab of FSUIPC (registered version)

Thanks Bill, I knew there was something to do about this, now I'm sure.
