The other day I was out flying and learning how the airport/runway direct to AP feature worked. I was able to do 3 "approaches" and found it to be a very good tool. I found 2 things that still have me a bit confused.
On one of the approaches it appears I active the VNAV too close to the runway, so the AP only did the navigation direction but did not do any altitude changes, even though the altitude preselected based on threshold height.
Based on the above I tried to arm the VNAV portion 20+ miles out, using HDG bug to intercept the extended centerline of the runway. What I noticed there is it would not allow me to select the VNAV until we were closer to the airport.
Is there a range of distance to airport that is needed to both capture the vertical?
It would still be awesome for a good how to video on this feature, and I am hoping in the future it can be selected as part of a longer flight plan and not just direct to.
