To achieve maximum range, what should the pilot do as fuel is consumed?

Achieving maximum range during flight involves operating the aircraft in a manner that allows it to cover the greatest horizontal distance per unit of fuel consumed. As fuel is consumed, the weight of the aircraft decreases, affecting its performance.

To maximize range, it is essential to fly at the most efficient speed, known as the best range speed. This speed is generally lower than the maximum speed and is closer to the aircraft's endurance speed. By decreasing power to maintain a constant airspeed that is optimal for range, the pilot can avoid using excess fuel that can come from flying at higher speeds or climbing excessively.

Maintaining a careful balance of fuel consumption and airspeed allows for maximum distance to be covered, making it critical to reduce power as necessary to stay within the range-sustaining parameters. This strategy helps ensure that the aircraft can glide further on the remaining fuel, ultimately extending the maximum range flight capability.

In contrast, increasing power would lead to higher fuel consumption without a corresponding increase in range, while maintaining power or reducing altitude might not optimize the flight for the given fuel efficiency needed for maximum range.
