If the fuel quantity is 47 gallons, how long can the aircraft fly at cruise power?

To determine how long an aircraft can fly at cruise power with a fuel quantity of 47 gallons, you need to consider the fuel consumption rate during cruise. The cruise fuel consumption rate is typically expressed in gallons per hour.

In this scenario, if the aircraft has a fuel consumption rate that, when applied to 47 gallons, results in a flight time of 3 hours and 22 minutes, then that would clearly be the correct calculation. This means that at the given fuel usage rate, 47 gallons would allow the aircraft to sustain cruise power for that duration.

By comparing this estimated flight time with common consumption rates for various aircraft, the figures align well with standard performance metrics observed in flying operations. The other options would imply either a higher consumption rate or an impractical flight time given the fuel available, making them less applicable in this situation.

Ultimately, based on the fuel quantity and the calculated flight duration at cruise power, the correct answer reflects a realistic operational scenario consistent with the aircraft's performance data.
