The best glide speed with the aircraft clean is approximately how many KIAS?

The best glide speed for an aircraft typically refers to the speed at which the aircraft will achieve the maximum distance for a given altitude lost, often referred to as the "best glide ratio." This speed is critical for pilots to understand as it allows for the most efficient descent during an engine failure or when gliding is necessary.

When the answer indicates that 125 KIAS is the best glide speed, it reflects a balance between aerodynamic efficiency and control of the aircraft. At this speed, the aircraft's wings are generating optimal lift while minimizing drag. This allows the pilot to cover the maximum horizontal distance per foot of altitude lost.

The specific best glide speed can vary slightly depending on the aircraft model and weight, but in many general aviation aircraft, 125 KIAS is considered an effective standard. It is essential for pilots to know their aircraft's best glide speed for safety and effective emergency management. By maintaining the correct speed, pilots can optimize their glide performance in emergency situations, thus affording them more time to assess their landing options.

Understanding this speed can also help pilots in training, as they practice emergency procedures that involve engine failures, emphasizing the importance of maintaining the right speed to achieve the best outcomes during such scenarios.
