Accelerated Stall Speed Calculator

Estimate accelerated stall speed and load factor from 1-G stall speed and bank angle for coordinated level-turn training.

50 kt stall speed at 60° bank

A 50 kt one-G stall speed at 60° bank becomes about 70.7 kt: 1 / cos(60°) = 2 G, then 50 × √2 = 70.7.

This assumes a coordinated, constant-altitude turn. A descending or uncoordinated turn does not necessarily have the same load factor.

Accelerated stall speed = 1-G stall speed × √load factor, with coordinated level-turn load factor based on bank angle.
