Hi, This thread is similar to one in the Misc Section....


Do you find that your options are limited by the 'Coffin Corner' such that speeds must be kept between 370-500 Kts at FL350 and even less than that at higher FLs.

Apparently the U2 could have a speed range of just 5 Kts at maximum altitude.
