PSS crash

<< < (2/3) > >>

EHM-1592 Niels:
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.

EHM-1365 Benjamin:
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 :|

EHM-1592 Niels:
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:>

EHM-1365 Benjamin:
Well I'm all out of ideas then ;)

Just hope it doesn't happen again!

EHM-0654 Murray:
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...
