Yesterday i was training to land on Sukhumi in bad weather with the help of the divert page and putting the waypoint parameters on NAV 3D, COMPUTED VANGLE and SCALE on APPROACH. I was surprised that the computed angle was 1.5° which give a flat approach. I remember havind used this method a few weeks ago and the computed angle was 3° which seems to be a better value. Can someone tell me if he has the same angle or if i am missing something in my method ?
