What does TTCAFE stand for in IFR fuel planning?

• A. Taxi, Trip, Contingency, Alternate, Final, Extra
• B. Time, Total, Consumption, Airspeed, Fuel, Emission
• C. Takeoff, Trip, Contingency, Alternate, Final, Economy
• D. Tax, Trip, Contingency, Approach, Final, Extra

Answer: (B)

TTCAFE is a fuel planning mnemonic used in IFR to categorize the six components of fuel you must carry. Taxi fuel covers what you burn from engine start to takeoff. Trip fuel is the amount needed to fly from departure to arrival under planned conditions. Contingency fuel provides a safety margin for unforeseen factors like headwinds or deviations. Alternate fuel is the amount required to fly to a chosen alternate aerodrome if the destination isn’t available. Final reserve fuel is the mandated minimum reserve for IFR operations, ensuring you have a safety net if the flight plan changes. Extra fuel is additional reserve beyond the final reserve to cover delays or other unexpected needs. These six elements together form the basis of IFR fuel calculations.
