Hey,
First of all, thank you very much for the great work on the app – I use VFRnav regularly and think the implementation is really excellent.
A feature request that would help me when flying and planning:
Would it be possible to display the Maximum Elevation Figures (MEF) in the grid squares on the map?
The MEFs indicate the highest terrain elevation or highest obstacle within a map quadrangle (including safety margin) and are very useful for quickly estimating the minimum required altitude for safe terrain clearance at a glance. Especially when planning a route in unfamiliar terrain, this could further improve situational awareness.
Perhaps this could be a worthwhile addition for a future update.
Many thanks and kind regards
