If you are required to fly for 620 NM under VFR conditions, how much AvGas would you need?

To determine the amount of AvGas needed for a flight of 620 nautical miles (NM) under Visual Flight Rules (VFR), you must consider the aircraft's fuel consumption rate, typically measured in gallons per hour, and the estimated ground speed or the time it will take to complete the flight.

Assuming you know the aircraft's fuel burn rate and average speed, you can calculate the total flight time. For example, if the aircraft has a cruise speed of 150 knots, the flight duration would be approximately 4.13 hours (620 NM divided by 150 knots). If the aircraft consumes 8 gallons per hour, the total fuel required would be roughly 33 gallons for this specific flight (4.13 hours multiplied by 8 gallons per hour).

While 34 pounds might suggest a miscalculation in fuel weight, you can convert gallons to pounds for AvGas by using the general conversion that one gallon of AvGas weighs about 6 pounds. Therefore, for 34 pounds of fuel, it would correspond to approximately 5.67 gallons, which does not align with the 620 NM flight requirement under the VFR scenario.

In the case of option A, suggesting 340 pounds, implies a misunderstanding since this weight
