Induced drag is a function of the vortices surrounding the wing.
Those vortices vary in strength with lift, not angle of attack.
Not so. The induced drag of an aircraft in high-speed cruise is much

This can be a good thing, for all their associated features that we

Hmm, nasty enough?

hardware to hopefully achieve an FAA (and JAR) certified sim by late
summer / early fall. The commercial fdm will run as a seperate
