Hi
first Baro iniciating & ident and ON
2nd mode NAV or GPS to choose
if you want to follow a FPL mode GPS , if you want follow VOR or NDB mode NAV that is in back left of the GPS buton .
after you switch ON your AP & select ALT after you select your NAV you see on the screen GPS "ROL" your AP is ON ROL is for stabilise your plane in flight .
Now re-click on NAV mode and your DHC2 follow the FPL .
that i do with it ...
One thing more : don't look any more on external view , need to stay in your VC sometime the AutoPilot over shoot segments and don't turn...., at this moment need to increment your heading pointing the segment after turning , i don't know why but i find this solution ..
