I think it is perfectly reasonable to do some planning with the profile (I am not suggested for exact terrain clearance - epsecially obstacle!) but it gives a good visual of airspace above the tarrain so when planning around complex airspace, you can move the waypoints and "see" what kind and height of airspace you need to deal with and then optimise the route. This is especially useful for the Restricted airspace avoidance in some parts of s/e france bordering lux/germany. I would always do final planning on a real chart! Just wish it also had a "dont show me airspace above xxxx" on the charts trying to click around and avoid higher airspace is a pain.
The co-ordinates I refer to are the ICAO Plan GPS in NddmmmEdddmmm
and very strange WP2/N0146F050 (not sure WP2 is know outside my plan!) and it ommits the actual location of WP2 just giving them waypoints either side. So they know I am changing levels but not where! The AIS system does not accept these you need to move the N and E and truncate the number of
Does this not happen for you? (ver 9.160 (build 10021))
