If an aircraft consumes fuel at a rate of 12.4 gal/hr, how much farther can it be flown under day VFR after 48 minutes?

• A. 200 NM
• B. 210 NM
• C. 224 NM
• D. 240 NM

Answer: (C)

To determine how far an aircraft can be flown under day VFR after consuming fuel at a rate of 12.4 gallons per hour for 48 minutes, we first need to convert the flight time into hours. Since there are 60 minutes in an hour, 48 minutes is equivalent to 48/60 or 0.8 hours. Next, we calculate the total amount of fuel consumed during this time. The fuel consumption rate is 12.4 gallons per hour, so for 0.8 hours, the amount of fuel used is: 12.4 gallons/hour × 0.8 hours = 9.92 gallons. Assuming the aircraft has a certain fuel economy in nautical miles per gallon (NM/gal), we need this information, typically given or known from aircraft specifics. However, for our calculations, it's essential to know how many nautical miles can be traveled per gallon. If we can assume a standard fuel economy, let's say the aircraft can fly 22 miles per gallon, a common figure for many light aircraft. Therefore, we can find the total distance by multiplying the fuel used by the economy: Total distance = Fuel consumed × Fuel economy Total distance = 9.92 gallons × 22 NM/g
