I'm having trouble figuring out why the AP sometimes does not intercept the GS as I'm expecting it to do.
This has occurred on ILS and LPV approaches.
Is there a requirement for VER ARM to be selected at some point in the approach before GS intercept?
Am I arming it too late? Or is there some other issue at work?
Is there a manual that I've missed that speaks to approach procedures.
I'm a retired airline pilot, but relatively new to the AF 3400 and the RV-10 I am flying.
Please excuse my ignorance and point me in the right direction to tighten up my instrument procedures.
Any help would be much appreciated.
