What is the best glide speed in clean configuration?

Explanation:
The best glide speed in a clean configuration is important for maximizing the distance an aircraft can travel when engine power is lost. This speed is carefully calculated to achieve the optimum lift-to-drag ratio, which allows the aircraft to glide further while maintaining control effectiveness. In the case of the chosen answer, a glide speed of 125 KIAS has been determined through flight tests and performance charts to provide the best performance under these conditions. At this speed, the aircraft achieves a balance between lift generation and drag. Slower speeds may lead to increased drag and loss of altitude efficiency, while excessive speeds could result in reduced control authority and increased aerodynamic drag. The best glide speed also assumes the aircraft is in a clean configuration, meaning flaps and landing gear are retracted, which contributes to achieving that optimal aerodynamics. Therefore, the selection of 125 KIAS reflects a well-researched performance characteristic that enhances safety and efficiency in glide scenarios.
