FAA Aircraft Dispatcher Practice Exam

The accurate additional fuel allowance required after reaching the furthest alternate is 45 minutes. This regulation is in place to ensure that aircraft have sufficient fuel to safely continue to a different alternate airport if needed. The 45-minute fuel reserve takes into account unforeseen circumstances such as weather changes, air traffic control delays, or other operational factors that could necessitate additional flying time. This requirement is crucial for maintaining safety standards and is part of the broader operational fuel planning guidelines mandated by aviation authorities. Knowing this allowance helps dispatchers plan more effectively, ensuring that the flight can manage diversions and last-minute changes without encountering fuel emergencies.
