3月18日的Glider Polar应用程序分析

Glider Polar predicts the glide performance of any glider. The user can vary the glider's gross weight and headwind component and immediately see the effect on glider performance. Experienced pilots can use the app to see how water ballast affects the glide ratio and cruise speed. For those new to gliding, the app clearly illustrates the effect of wind and weight on performance.
