MiG-25 Ai speeds

[cauldron]

In DCS I cannot get M2.8 from even an empty MiG-25, and its highest MACH occurs at 52,000' any higher and it gets worse. This seems fairly poor performance where the region of greatest available thrust should be at 17.5km to 18km (59.000') and be limited to M2.83. The Ai comes no where near this. Also the choice of missiles evasion seems to be the same for an Ai plane flying at 20,000' as for a high MACH high altitude - pitch up and turn to the side, which makes no sense for very high MACH and Altitude.

Ran a test on latest Beta build:

 

Four mig-25's empty hard points, 50% fuel w/ unlimited fuel option 'on', standard atmosphere, zero winds all altitudes:

 

1 @ 65000feet, 1@ 59000feet, 1@52000feet, 1@50k all spawned under initial conditions of M2.83 which is accepted by the Mission Editor as well as straight waypoints to the same conditions...

 

@65k: 394 IAS, 1436 TS, 2.50 M... after 4min flight time ... 378 IAS, 1390 TS, 2.42 M

 

 

@59k: 479 IAS, 1523 TS, 2.65 M ... after 4min flight time ... 472 IAS, 1497 TS, 2.60 M

 

 

@52k: 588 IAS, 1582 TS, 2.76 M ... after 4min flight time ... 588 IAS, 1579 TS, 2.75 M

 

 

@50k: 602 IAS, 1542 TS, 2.69 M ... after 4min flight time ... 603 IAS, 1543 TS, 2.69 M

 

Note: the only stable altitude is the 50k one, and the best speed is at the 52k regime.
