An aircraft weighing \( 60 \) kN pulls a manoeuvre at a load factor of \( 2.5 \). The lift being produced is

  • A.90 kN
  • B.150 kN
  • C.60 kN
  • D.24 kN

Answer: B

Correct answer: 150 kN

\[ L = n W = 2.5 \times 60 = 150\ \mathrm{kN}. \] The load factor is by definition the lift divided by the weight, so at 2.5 g the wing is carrying two and a half times the aircraft’s weight - and everything the wing supports feels the same multiple.
