So i was watching this Lear 60 flightaware track and he is flying to my home TVC but at only 27k. He also filed to leave in awhile and its the same altitude. I figured it was a mistake but he actually flew all the way here at 27k…anybody know the reason? pressurization isssues? can a lear 60 have sea level pressure at 27k maybe for medical reasons had to have it?
