## What is Glide2?

Impossible Turn Calculator

Know before you go. The "impossible turn" — returning to the runway after engine failure on departure — is one of aviation's most critical and least-practiced decisions. This app helps you calculate whether you can make it back.

Enter your numbers, get your answer.

Select your aircraft or add a custom one with your own glide ratio, best glide speed, and MTOW
Set your departure altitude, bank angle, reaction time, wind, and density altitude conditions
See whether the turn is survivable before you ever leave the ground
Features:

Built-in aircraft profiles with real-world performance data
Custom aircraft support — add any type with your own specs
Density altitude calculations with OAT and altimeter setting
Bank angle and weight effects on stall speed
Wind correction
Clean, dark instrument-panel interface
For pilots who plan ahead.
