In reference to glide performance, what should you aim for in terms of configuration?

A clean configuration is optimal for glide performance because it minimizes drag, allowing the aircraft to maintain better lift and efficiency during the descent. The term "clean configuration" refers to the aircraft’s state where flaps are retracted, and landing gear is up. In this configuration, the aircraft can achieve a longer glide distance and maintain a more controlled descent rate.

This is crucial in situations such as engine failure or needing to glide to a landing, as it enables the pilot to maximize altitude and distance. The other configurations, such as partial flaps or full flaps, increase drag, which can significantly reduce the aircraft's glide ratio and overall performance. Similarly, having the landing gear down can also create additional drag, hindering the glide capability. Therefore, aiming for a clean configuration is essential for optimal glide performance.
