According to an article I read in Aviation Week a couple of years ago, the Max supercruise speed is M 1.82 and normal supercruise speed is M 1.5, both take place above 50000 ft. Given the current altitude restriction of 44000 ft, which hopefully will be lifted when the valve of the anti-G vest is replaced by the end of the year; Does anyone know how much, if any, effect the restriction might have on the plane's ability to supercruise? Please note that I'm not soliciting, nor am I expecting any classified info on this subject. Just looking to learn something out of meaningful discussion.
