An airplane stalls in straight flight at 50 knots. It then makes a turn with a load factor of 4 Gs. At about what speed does it stall in the turn?

  1. 200 knots
  2. 100 knots
  3. 75 knots
  4. 50 knots
Show answer

Correct answer: 100 knots

Stalling speed increases in proportion to the square root of the load factor. A load factor of 4 doubles it.
