Lift and stall speed at 45° bank

At 45° bank in a coordinated level turn, load factor is 1 / cos(45°) = 1.414 G. The stall-speed multiplier is √1.414 ≈ 1.19.

Lift must rise about 41% to maintain altitude, while stall speed rises about 19%. These percentages describe different quantities.

Load factor in a coordinated level turn = 1 ÷ cos(bank angle).
