Which of the following correctly completes the flight planning values for Start/Taxi/Takeoff, climb to 12,000', and per-approach fuel?

Which of the following correctly completes the flight planning values for Start/Taxi/Takeoff, climb to 12,000', and per-approach fuel?

• A. Start/Taxi/Takeoff: 60 lbs; To climb: 40 lbs and 6 minutes to 12,000'; Per approach: 40 lbs
• B. Start/Taxi/Takeoff: 50 lbs; To climb: 50 lbs and 5 minutes to 12,000'; Per approach: 50 lbs
• C. Start/Taxi/Takeoff: 40 lbs; To climb: 60 lbs and 4 minutes to 12,000'; Per approach: 60 lbs
• D. Start/Taxi/Takeoff: 70 lbs; To climb: 30 lbs and 3 minutes to 12,000'; Per approach: 50 lbs

Answer: (B)

Fuel planning across flight segments hinges on estimating how much fuel you’ll burn during each phase and keeping a safe reserve for contingencies. Start/Taxi/Takeoff covers the engine start, taxi to the runway, and the takeoff maneuver, so you allocate enough fuel to cover those brief but essential activities. The climb to 12,000 feet shows how much fuel is consumed while gaining altitude, expressed as both an amount and the planned time to reach that altitude. Per-approach fuel is the buffer you set aside specifically for the approach phase, including potential delays or a missed approach. Choosing the plan with 50 pounds for Start/Taxi/Takeoff, 50 pounds with 5 minutes to reach 12,000 feet for the climb, and 50 pounds for the approach keeps the burn rate consistent across segments (about 10 pounds per minute during the climb). This consistency helps ensure you won’t run out before reaching your destination while still leaving a reasonable reserve for possible delays or a go-around. The other options mix larger and smaller amounts or longer/shorter climb times that wouldn’t align with a straightforward, evenly paced burn, making it harder to guarantee adequate fuel for the entire flight with the intended reserves.
