In every flight sim I've ever played, there seems to be a speed limit to the airplanes. Falcon 4.0 seems to have it at 1000 (I might be mistaken, I've only played that game once), in Nova logic's F-22 it's 800km/h, Jane's USAF 800km/h.
In Lo-mac, I can't seem to get any faster than ~1200-1400 km/h (is it even km/h?) Thus my plane's speed limit seems to be Mach 1. Whereas I see in nearlly every flight textbook that the Su27, F-15 and Mig29 are Mach 2 capable planes. Mig 25's are mach 3 capable planes, yet I've never seen them go that fast in the game yet.
So, am I doing somethig wrong or is this game programmed like that?
EDIT: Yes, I use full afterburners at low altitude and high altitude, limit varies around 1200-1400, never got anywhere near 2000
