Using airplane data, please add simple fuel planning functions that display alongside the waypoint boxes. Allow for refueling along the way, sometimes more than once. Allow for negative fuel remaining numbers (maybe in red?) so we dn't forget to plan to refuel. I prefer units of gallons but don't know what the consensus is.
To assist with fuel planning, add max fuel on board and useable fuel in an airplane's profile.
Sincer iFly doesn't connect to sensors (future update?) we would have to compare planned versus actual manually at a time of our choosing.
