Fuel Reserve Requirements for Pilots

Read the official rule

The document outlines the fuel reserve requirements for pilots as specified under the RFEUA regulations. It includes several categories of fuel that must be calculated, including contingency fuel for unforeseen circumstances, destination alternate fuel for missed approaches, and final reserve fuel for emergencies, which must cover at least 30 minutes of holding at a specific altitude. Additionally, operators must account for extra fuel to manage anticipated delays or specific operational needs, ensuring all necessary reserves are in place for safe flight operations.

Key points

  • Pilots must plan for various fuel categories, including contingency and final reserve fuel.
  • Final reserve fuel should ensure an additional 30 minutes of flight time at holding speed.
  • Operators must include contingency fuel to accommodate unforeseen issues or delays.
  • Additional fuel may be added at the pilot's discretion for predicted operational constraints.
