Title: (Optional) Explain the fuel-dump system.
Course: Aircraft Pilot Training I (20053-I) > Section: Understanding Aircraft Systems: Fuel Systems

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.
