How to Use This Calculator

Enter your current altitude AGL (ft) and aircraft best glide ratio (L/D) from the POH.
Set best glide indicated airspeed (KIAS) and the headwind or tailwind component (kts).
Enter bank angle if maintaining a turn, and current aircraft weight (lb) if weight correction is needed.
Review still-air glide distance (NM and SM), wind-adjusted range, descent rate (fpm), and time to ground.
Select the best glide speed indicated — gliding faster or slower than best glide reduces range.
