Turn rate

The delta wing is often criticised for it´s relatively poor sustained turn rate(STR). The Americans place great emphasis on STR and it´s importance in a turning fight is beyond dispute. However the turning fight only very rarely occurs and whilst a high STR is desirable the importance of a high instantaneous turn rate(ITR) should not be overlooked. A high ITR is more important when trying to break a missile lock or radar lock than a high STR.
Listed below are some observed turn rate parametres exhibited by the Mirage 2000 (Internal fuel).

At 30,000 –35000 ft and 5G the ITR is 10- 12°/second.
At 36,000 ft and Mach 2 the Mirage can maintain a 3G turn.
At an altitude of 40,000 ft and Mach 1.05 pulling the stick nearly full-aft produces 4.5G and an angle of attack(AoA) of 25°.
At 22,000 ft and Mach 0.9 the application of 8G produces an ITR of 20°/second. The AoA is then 27°.
The application of 9G increases the ITR to 24°/second and 28° AoA.
