am aware that the F18 uses toe in on landing in order to generate drag; this means the engine can be run t a higher RPM and is thus more responsive if a go around is reqired after missed cable.
When they got rid of the airbrake, as is stated above, rudder deflection was used as a replacement. apparently the FBW system simulates the performance of the old aircraft's airbrake by use of various control surfaces. very clever!
Not sure about TO though, could be to aid some form of flow control; I am aware that at one point the 18 had severe vortex bursting problems early in its life; apparently at high alpha the extremely thin (and flexible) tail surfaces were fatiguing after only ten hours!
