Aircraft Nose Goes Down When Disconnect the A/P

Hi, Guys!

When I try to land any aircraft in infinite flight, I turn off the A/P at 100 or 200ft AGL, its nose goes rapidly and fastly to down position and I barely pull lots of yoke to get it to steady position. I try to make my mobile position well to stabilise yoke while landing.

I’ve used B738 and B777 so far. I land the aircraft at 135 to 145knots with full flaps. Kindly help me.

I recommend trimming your aircraft

or here’s a great topic made by Kuba_Jaroszczyk

I concur with @VibrantPixel. It is imperative to trim your aircraft to avoid nose-diving when you disconnect the autopilot. I recommend about 15-35% of trim for all aircraft (with some exceptions).

Try calibrating your controls before disconnect A/P, always works for me. 🌞

Yea I have a simaller problem and my landings are harder because of that

All right. 40 degree trim has worked for me on B777. Nice. But when i turn AP Off at 200AGL, the nose sometimes turns right or left and aircraft goes away from runway. What about this guys?

Thanks to all for helping.

Maybe you went too fast?

Trim?

Calibrate???

Just calibrate before Disconnect the AutoPilot. Put a good configuration for your trim %

Calibrate your device. Trim till the yoke is in the neutral position or match your device pitch with the yoke’s position. Works for me! :)

I understand what you mean. When I disconnect the A/P i put my device to around the same as it was when I calibrated before takeoff. I do this every flight and it really works. Sometimes after I disconnect, I have to make sure that I shut the A/P off because its so stable. I hope this helps you!!

Honestly I still have this and id say my landings and approaches are decent. But how i counteract this is I 1) anticipate the nose drop with a really gentle pull back, being super smooth with the device and pulling down the trim to have positive trim. Make sure the trim isnt adding +5% you need plus 1. This method sounds like a lot but once you keep practicing this it’ll be second nature. I dont even notice the nose drop anymore when my plane is untrimmed. 2) the first way i dealt with it was just taking the AP off higher maybe like 700-500 ft so the nose is not dropping at a super critical phase of flight. I usually take out the AP around the 1000ft call out or in the range I said before.

Hope this helps

I’ve read all replies. Thanks guys. First I calibrate and then increase trim +10. It is working for me
