Stall Speed vs Load Factor

Accelerated stall speed rises with the square root of the load factor.

Formula

Vs,n=VsnV_{s,n} = V_s\sqrt{n}

Variables

V_{s,n}Stall speed at load n
V_s1g stall speed
nLoad factor

Example

2 g: stall speed × 1.41

Did You Know?

Pulling g raises stall speed by the square root of the load factor — tight turns can stall a fast aircraft.
