Fuel Planning Basics: Mastering Flight Economy

Fuel efficiency isn't just about saving virtual money — it's about mastering flight planning and developing true airmanship. A precise pilot knows that carrying too much fuel "for safety" makes the aircraft heavier and needlessly increases consumption. Mastering fuel planning basics is the first step to climbing PilotLeague's Efficiency rankings.

In this guide, we break down the fundamental fuel blocks every pilot needs to know, from trip fuel to final reserves, and show you how PilotLeague tracks your fuel efficiency in real time.

Understanding Each Fuel Block

• Trip Fuel: The fuel required from takeoff to touchdown at your destination. This is your baseline consumption calculated from route distance, altitude, and aircraft performance.
• Contingency Fuel: A margin (typically 5% of trip fuel) to cover unexpected weather deviations, ATC rerouting, or forecast errors.
• Alternate Fuel: The fuel needed to fly from your destination to a diversion airport if you cannot land at your primary destination.
• Final Reserve: The critical minimum — enough fuel to hold for 30 minutes at 1,500 ft above the alternate airport. You should never consume this fuel in normal operations.
• Extra/Discretionary: Additional fuel the captain adds for comfort margin. Weather uncertainty, limited alternates, or personal minimums justify carrying extra fuel.
