X-31 flight test update

The goals of the tactical utility flight test are to verify the basic tactical lessons learned in simulation and determine the situational awareness implications of post-stall maneuvering. Tactics and lessons learned from post-stall engagements will supplement current fighter tactics and complement future fighter tactics development. Although the present envelope of the X-31 for carefree post stall (PST) use is limited to 225 KIAS versus 325 KIAS in simulations, the same initial conditions used in 'Pinball II' are being utilized in flight test. Starting conditions up to 325 KIAS are being flown during the build-up phase leading to the full close in air combat (CIC) evaluations. The flight control program has been modified to limit PST entry to below 225 KIAS. Full aft stick application above 225 KIAS cannot command angle of attack (AOA) in excess of 30 deg.
