Trim wheel goes haywire when arming autopilot modes on ground

[blondejfx]

Hello,

First of all - initial impressions of this add on are fantastic. Really love it.

One thing I've noticed though is that when you arm autopilot modes (LNAV, HDG SEL etc.) on the ground the trim wheel starts to go crazy.

This is without pressing any of the CMD/CWS buttons.

Thanks for the heads-up, I will verify this! Normally only the pilot and the autopilot can trim the aircraft, both on the ground and in the air.

One thing - in the 737 Classic you do not ARM any modes on the ground, you use the TOGA buttons to trigger the TOGA mode (for takeoff). Activate LNAV when passing 50 feet, activate a pitch mode when passing 400 feet (earliest).

Hi @blondejfx I just tested this and for me the trim does not start to run if I ONLY use the Flight Directors.
