âŠī¸ Load Factor & Stall Speed in Turns
G load and higher stall speed at any bank angle
About this calculator
In a level turn the wings must produce more lift than in straight flight, and that extra lift is the load factor, measured in Gs. It equals one divided by the cosine of the bank angle, and your stall speed rises with the square root of the load factor. That is why airplanes stall in steep turns at speeds that feel perfectly safe wings-level.
Tip: at 60 degrees of bank the load factor is exactly 2 Gs and stall speed is 41 percent higher. Most stall-spin accidents start with exactly this surprise.
