I flew LX656 from Zurich to CDG and the flight was bumpy because of bad weather. The aircraft took too long to reach the cruising altitude. What amazed me was, overhead LCD displayed 775 Km/Hour as cruise speed and flight level 350. Aircraft was A319 and flight was full. The aircraft only breached 850 Km/Hour during descent.
Was that because of full load flight and/or non optimal trimming of aircraft by the loadcontroller? Any answers?

I think that’s your coat over there, Paul.

Would that have anything to do with a retarded throttle to save fuel???
It’s not the throttles fault it’s a bit simple. 🙁

…or headwind.
Quiet possible as the displayed speed was ground speed.
What I want to know is whether trimming can cause such things? I had basic loadcontroller training and generally we have a range of trim index within which our actual trim should land in order for the aircraft to take off. For example for the said flight the schedule says it is 21.08 forward to 51.38 aft.
Can these extreme limits cause such cruise speed deviations?

According to who?……
I took the return flight LX645 two days after that and the ascent was smooth and quick. In the earlier flight, half of the 75 minutes flight time we were just ascending to 35K feet. Have flown on B737s/A320s earlier and there general cruise altitude is about 36K and the cruise speed around 950 Km/Hour (as per the captain’s PA announcements :D)
