Work out load factor in a turn instantly with clear inputs, formula shown and shareable results.
In a level turn lift must both support the weight and turn the aircraft, so load factor equals 1 divided by the cosine of the bank angle: 1.41 g at 45 degrees, 2 g at 60 degrees. Stall speed rises with the square root of load factor, so a 60 degree bank raises stall speed by 41%.
Load factor in a turn
n = 1 / cos(bank); stall speed in turn = Vs x sqrt(n)
Aviation results are planning estimates only. Always verify take-off, landing, fuel, weight and balance figures against the certified Aircraft Flight Manual, current performance charts and applicable aviation regulations before flight.
Stall happens at a fixed maximum lift coefficient. More lift required means a higher speed is needed to generate it, and lift scales with the square of speed.
60 degrees gives exactly 2 g. Beyond that the curve steepens sharply — 75 degrees is nearly 4 g.
