Yes, you will need to place the EFIS into ARM to allow the NAV switch over. ALT is altitude bug -> ARM is wait for couple while flying bug -> NAV is coupled and alt bug ignored.
That’s a little confusing. Are you saying that when I have my EFIS in Lat Nav, Vertical will automatically switch to Arm? I understand having Lat in Nav to follow the course, not in HDG. But please clarify whether I have to manually select Vert Arm or if left in Vert Alt with Lat Nav the EFIS will automatically switch to Arm.
Thanks
yes
you need to be vertical arm not alt
ive had my plane for10 years and always left my efis in ver arm
somehow it got changed to vert alt and ap would not couple
once couple it changes to nav
