5400 upgrade from non-functional 4500. I'm having trouble calibrating flap position. The 15.1 install manual page 184 indicates there would be a full-up, center, and full down entries but all I have is full up and full down flap position on both the AoA donut and the position display. I rarely use full flaps but I frequently use 10-20 degrees. The AoA and flap position worked fine on my 4500. How can I make it work on the 5400? Or can I? Is full up or full down all I get?
