Just a couple of features I thought could come in handy.
1.) I'd like a two aircraft formation.
2.) I'd like the ability to have a "wingman mode". With "wingman mode" the planes would work together more and possibly send messages like "check 6" and so forth. I know that creating it could be rather difficult and time consuming but it's just a thought.
3.) A way to look at aircraft speed and climb information in the editor. I was thinking of a cross between the E6B data and the speed and climb charts in the hanger. Or, you could change it so that the "flight" was required before the "route". That way it could check your segments against the aircraft performance and highlight any sectors that exceeded aircraft performance capability.
Who knows, perhaps I could get a real E6B calculator.
But then I'd have to lean how to use a slideruler!
Oh, wait I can already do that.
