What’s the absolute minimum speed a plane has to go for it to stay in the air?
In: Physics
Depends on the plane (faster planes usually have higher stall speeds), whether or not the flaps are deployed (flaps reduce stall speed) and how much it weighs (more payload and fuel increases stall speed).
Typically I believe it to be (flaps down) about 50kn for a small plane, around 80kn for a commercial jet and about 120kn for a fighter jet.
