An aircraft of \( 60\,000 \) kg is designed to a limit load factor of \( 2.5 \). The limit wing load is nearest to

  • A.588 kN
  • B.150 kN
  • C.2943 kN
  • D.1471 kN

Answer: D

Correct answer: 1471 kN

Weight first, then the load factor: \[ 60{,}000 \times 9.81 = 588{,}600\ \mathrm{N} = 589\ \mathrm{kN}, \qquad 589 \times 2.5 = 1471\ \mathrm{kN}. \] The 588 kN offered is the 1 g weight with the load factor omitted, and 2943 kN is five times the weight. The ultimate load would be a further 1.5 times this, at about 2207 kN.
