With a rate of fuel consumption of 19 gal/hr during a flight given the specified conditions, what amount of fuel would be consumed over a flight distance of 200 NM?

To determine the amount of fuel consumed over a flight distance of 200 nautical miles (NM) with a fuel consumption rate of 19 gallons per hour, it is essential to first establish the flight time. This can be done using the True Airspeed (TAS) or Ground Speed (GS) of the aircraft.

Assuming a typical cruising speed for small aircraft, let’s say the TAS is around 120 knots. Since 1 knot equals 1 nautical mile per hour, a TAS of 120 knots means the aircraft covers 120 NM in one hour.

To calculate the flight time required to travel 200 NM at 120 knots:

1. Flight time = Distance / Speed

2. Flight time = 200 NM / 120 knots = 1.67 hours (or approximately 1 hour and 40 minutes).

Now, we can calculate the total fuel consumed during this flight time:

1. Fuel Consumption = Fuel rate × Flight time

2. Fuel Consumption = 19 gallons/hour × 1.67 hours ≈ 31.7 gallons.

This calculation accurately reflects the fuel burned over the given distance based on the fuel consumption rate and flight time. Therefore, the correct answer is indeed 31.7 gallons,
