Closed nickjzx closed 10 months ago

nickjzx commented 10 months ago

Describe the bug

Nose up trim when using f laps 50 is basically full nose up

Steps to reproduce

Fly approach at Flaps 50, somewhere around 450000lb+ area

Expected behaviour

Not going from 9.0 on trim to 15.5 and still requiring lots of back pressure to keep the nose up.

Evidence

FS2020_20231219_213536_R

Simulator

Microsoft Flight Simulator 2020 (MSFS)

Agreement

Looks like 771 makes mention of this as well, although it's more manageable at flaps 35.

That was my post. I usually land with flaps 50, but if its better at flaps 35, I will definitely try that and see what happens.

I have also, if you see post #794, that the autopilot has quite a bit of back pressure when on the glideslope. The nose dive only happens once you manipulate the elevator axis.

Flew flaps 50 on .26 last night at nearly max ZFW and this seemed to be fixed. Great work guys!
