I believe the autopilot in IF could use a tune-up, just like the Systems page got! ;)
My biggest request for the autopilot update would be: allow an “ARM” and “CAPTURE” mode for LOC & GS.
Irl, on radar vectors or just in general, one can be flying with altitude hold and heading select, be given an intercept heading to a localizer/other Nav course and one’s plane will hold the HDG you set until the plane Captures the course.
The same is true for altitude hold until glideslope intercept.
This update would enhance the realism of the autopilot and create an neater radar vector pattern with minimal localizer overshoots and better glideslope control.
Happy flying, and thanks FDS for this amazing product.
