How much fuel will an airplane require if it is consuming 72 pounds per hour and flying at a groundspeed of 110 knots?

To determine how much fuel the airplane will require, we need to calculate the total fuel consumption over a specific period of time based on the fuel flow rate and then convert that amount into gallons.

First, we need to find out how long the airplane will be flying. The groundspeed of the airplane is 110 knots, which means it will cover 110 nautical miles in one hour. Given that fuel consumption is provided as 72 pounds per hour, we can use this information to derive the amount of fuel used.

1. Fuel Flow Rate: The airplane consumes fuel at 72 pounds per hour.

2. Time Calculation: If we want to fly a specific distance, we must translate our fuel flow and groundspeed into a total fuel requirement over time.

3. Conversion from Pounds to Gallons:

• Aviation fuel (like Jet A or Avgas) typically has a specific gravity which allows us to convert pounds into gallons. A common conversion factor is approximately 6 pounds per gallon for Jet A fuel.

• Therefore, to find out how many gallons are equivalent to the fuel consumption, we can divide the fuel consumption in pounds by the weight of a gallon of fuel.
