A pilot is planning a mission that requires 140 gallons of fuel. The aircraft consumes fuel at a rate of 35 gallons per hour. If the pilot must also carry a 30% reserve fuel based on the mission's required fuel, how many total gallons of fuel must be loaded?
- A196 gallons
- B175 gallons
- C182 gallons
- D210 gallons
Show answer & explanationAnswer & explanation
Correct answer: C. 182 gallons
First, calculate the amount of reserve fuel needed (30% of 140 gallons). Then, add this reserve fuel to the mission's required fuel to find the total fuel to be loaded.
Why the other options are wrong
- A. This option is incorrect; it might result from miscalculating the percentage or adding incorrectly.
- B. This option is incorrect; it might result from calculating 25% reserve instead of 30%, or other calculation errors.
- D. This option is incorrect; it might result from calculating 50% reserve or other significant errors.
Reserve Fuel Calculation
Reserve fuel calculation involves determining an additional amount of fuel, typically a percentage of the primary fuel requirement, to ensure safety margins or contingency for a mission.
- Reserve is usually a percentage of the *required* fuel.
- Total fuel = Required Fuel + Reserve Fuel.
- Crucial for aviation safety and mission planning.
Memory trick: Think of packing an extra snack, just in case, on top of your planned meal.
