Because I cannot get it past 320 mph, so I must be doing something wrong. I'm flying full real, radiator closed, trimmed, holding it steady + using MW50 and 110% power. If you guys can manage it, let me know how you did it! It's driving me nuts that I'm 100 mph short of the "book" speeds, even with an empty aircraft.

Thanks,

Ely

By the way, the best kph gauge speed I can get is 600 kph. So still way short of 685-690 kph at 21,650 ft.

True airspeed calculator, so at 320 mph indicated at 21500 ft you would have been going 454 mph.
There are other factors as well so lets just condider this a rough estimate.

TAS/IAS mistake?

Thanks, I wondered about that but thought that the speed bar was TAS.

Make sure you're using the Crimea map if you want to test something. There are no added variables on that map and you might get better results there.

Try and reach 650km/h at 2000 meters with the D-9. I bet you wont even come close.
