Which statement about the critical engine on a four-engine aircraft is TRUE?

  • A.It depends on the bypass ratio
  • B.It is an outboard engine, because it has the longest moment arm
  • C.It is an inboard engine, because it produces more thrust
  • D.All four are equally critical

Answer: B

With equal thrust the moment follows the arm, so the outboard engine sizes the fin. Propeller aircraft add a further asymmetry from slipstream and P-factor effects, which can make one side distinctly worse than the other.
