(Optional) Explain the fuel-dump system.

Explanation should include the following:

  • If an aircraft’s design landing weight is less than that of the maximum takeoff weight, a situation could occur in which a landing is desired before sufficient fuel has burned off to lighten the aircraft.
  • Fuel jettisoning systems are required on these aircraft so that fuel can be jettisoned in flight to avoid structural damage caused by landing the aircraft when it is too heavy.
  • Fuel jettisoning systems are also referred to as fuel-dump systems.
