Well - Haven't used it in a while but was planning a route with some altitude changes for airspace this morning and found that Altitude Planning on Map is not working for Multiple altitudes. Same issue on iPhone, 720 and 740b and Windows as follows:
- Add some waypoints to your plan;
- Click on altitudes;
- Select Multiple altitudes check box;
- Select options then Set altitude on map;
Now - Click on each waypoint and try to set a different altitude, it won't do it. They all change to whatever you select.
The only way I seem to be able to actually set multiple altitudes is by bringing up the flight plan page then clicking on the 'Set Alt.' link for each leg. Problem is since I can't see the map at that point, I can't see the airspace for purposes of choosing altitudes. Again it's been a while since I tried to do this and so my recollection could be off, wasn't this possible at one time?
