What is the 45 minute IFR reserve fuel in pounds?

• A. 1627 lbs
• B. 1200 lbs
• C. 1500 lbs
• D. 1800 lbs

Answer: (A)

In IFR planning, reserves are extra fuel carried to cover delays or holding in case the flight encounters problems after departure. The 45 minute IFR reserve specifically means you must have enough fuel to fly for 0.75 hours at the aircraft’s reserve burn rate. To turn that into pounds, multiply the reserve time by the aircraft’s fuel burn rate in pounds per hour. For the Longitude, the planning data use a reserve burn rate around 2,169 lb/hour. So 0.75 hours × 2,169 lb/hour ≈ 1,627 pounds. Thus the 45 minute IFR reserve fuel comes to about 1,627 pounds.
