What amount defines emergency fuel in pounds?

Emergency fuel is defined as the amount of fuel that must be on board to ensure safe operation in case of unforeseen circumstances that prevent a safe landing at the intended destination. The standard definition of emergency fuel is typically set at 100 lbs or less. This threshold is established to ensure that in the event of an emergency, the aircraft has a minimal but adequate fuel reserve to handle such situations without carrying excessive weight that could impede performance.

In operational contexts, keeping emergency fuel at 100 lbs or less allows for necessary weight management, which is crucial for flight safety, taking into account factors such as aircraft performance and fuel efficiency. This figure is generally recognized in aviation regulations and guidelines, making it essential for pilots and operational teams to be familiar with this limit to ensure compliance and safety in flight operations.
