My 2cts comments• Flight Envelope : pessimistic

–Reasonable under 30,000ft–Maximum mach at 36,000 / 40,000 ft should be 2.35 instead of 2.15

• Acceleration : accurate /pessimistic–Very realistic, and if not, (between 20,000 and 35,000ft) rather pessimistic

• Maximum Available G : optimistic–Between .5 and 1 G more than real life a low mach (< 0.45 at SL)–Largely over estimated in supersonic and at high altitude

• Maximum Sustained G : optimistic–between 1 and 2 G more than real life at sea level and low mach (< 0.45)–Largely over estimated in supersonic and at high altitude

• Roll Rate: very optimistic–Maximum value largely over-estimated (300 instead of 160)–Negative impact of high dynamic pressure under estimated

IN GENERAL

In level flight configuration, FF3 MIG-29 Fulcrum does not have the advantage versus the Viper (F16-C Blk52) it should have, especially at high altitude

In term of turn rate, the FF3 MIg-29 Fulcrum is closer to the Viper (F16-C Blk52) than it should be. Where the Viper should have a significant advantage
