For what situation is diversion fuel used?

Diversion fuel is specifically allocated for scenarios where an aircraft may need to divert from its planned route to an alternate landing site. This situation could arise due to various factors such as adverse weather conditions at the destination, technical issues with the aircraft, or emergency situations that require landing at a different airport.

The calculation of diversion fuel is an essential aspect of flight planning, ensuring that enough fuel is available for both the flight to the alternate airport and any potential holds before landing. This careful planning minimizes the risk of fuel shortage and enhances safety during flight operations.

Other options do not reflect the purpose of diversion fuel. Regular inflight consumption refers to the fuel used as the aircraft operates along its planned route without any need for diversion. Taxiing fuel is a separate consideration, focusing on the time and fuel required for ground movements before takeoff and after landing. Additionally, while long-haul flights may require careful fuel management and may include diversion fuel as part of their overall planning, the broader definition of diversion fuel applies regardless of the length of the flight.
