A330NEO Stall at Cruise Altitude

Hello,
I’ve been having issues with the A330NEO in Infinite Flight on and off, but the worst incident I’ve had was yesterday. I was flying the Delta A330NEO from SEA-HNL, and did a normal climb to cruise and leveled off at 37,000 and a speed of Mach 0.83. We went along normally for about 10 actual minutes (sped up on Solo mode), until we suddenly began loosing speed and the nose begain drifting higher. I noticed, and disengaged the autopilot. I tried bringing it up to full thrust and pointing the nose down to gain speed, but the aircraft still stalled and crashed into the ocean. I had brought the nose down to almost direcly down at one point (I then brought it to just below level to prevent a plumet into the water) but we kept loosing speed.
Does anyone know what may of happened?

Device: iPhone XS MAX
Operating system: Most recent (last updated yesterday)
Sim: Solo

Hello! Did you check if the aircraft had fuel at the time of incident?

Hi!
Thanks for your swift response! I did seem to have enough fuel, as I filled the tanks to the maximum allowance (so not to get into the MTOW zone) before my flight, so it should have plenty of fuel for much longer than 48 minutes.
Thanks!

You are very welcome! It does seem odd that it may happen but it could be a few things. My best advice would be just restart the app and if it happens again let me know! Hope this helps

If you haven’t already I’d strongly suggest using SimBrief as you can get real world flight plans and a ton of aircraft are supported. You will be given a detailed flight plan with realistic fuel loads based on the route, aircraft load, etc. It even takes reserves and diversion airports into account so you can be sure to take a proper amount of fuel instead of taking too much or too less. As far as the 330 goes…it is hilariously underpowered in game. In real life the aircraft can climb up to the high flight levels and fly efficiently while in game even at a lower weight, the aircraft still doesn’t want to climb.

Hi!
I’ll look into SimBreif! I already use Flight Plan Database, but they really mess things up sometimes. Once, they gave me a JFK-LHR routing that had a waypoint in China!
Thanks!

No worries, I hope that helps.

The A330 CEO and NEO’s climb performance is very poor in Infinite Flight. You have to cruise very low and climb very slow. Just the other day I was flying it on 50% load and barely could manage FL320.

Yes, exactly! I love flying the A330CEO, but the step climb departure is sort of tedious. Worth it though!

Hi, From your description you were high:

and heavy:

Heavy requires wings produce more lift, which they do by increasing the AoA (angle of attack).
And high means the air is thin, requiring even more AoA to produce the same lift from less dense air.

The symptom to look for is higher than normal AoA (which will be from the total of those two effects).

Drag increases from high AoA to the point that the available power eventually cannot effectively maintain speed.

This can cause an unrecoverable loss of speed, especially if wind speed/direction changes unexpectedly.

Assuming you have been able to hold the high altitude while heavy, a wind change can be enough to push you over the edge.

Again, look for the AoA growing too much (same as pitch angle only in level flight), or inability to maintain speed with power.

Stop climbing before the above happens too much, and you’ll be ok.

As you burn fuel weight the AoA decreases, allowing you to climb higher.

OK, thank you! This is really helpful! I’ll try another A330neo flight later today and see how this works out!
Thanks!!
