What does constant power management involve?

Constant power management refers to the practice of adjusting the aircraft's performance to optimize fuel consumption and efficiency as it progresses through a flight. The concept emphasizes the relationship between fuel usage and the weight of the aircraft. As fuel is burned, the aircraft becomes lighter, which allows for increased speed or altitude with the same engine power output.

Therefore, as an aircraft burns fuel, it can be beneficial to increase either speed or altitude to maintain an efficient flight profile. This ensures that the aircraft operates within its optimal performance envelope. Properly managing power while considering the decreasing weight of the aircraft allows for enhanced flight efficiency and can effectively reduce operational costs. This is why the concept of increasing speed or altitude as the aircraft burns fuel is integral to constant power management.
