Your glider's MIN SINK ism/s at km/h equals GLIDE ratio of !
Your glider's BEST GLIDE is at km/h. This is true only in completely calm air with no wind.
When you want to fly with MIN SINK and when you want fly with BEST GLIDE speed? Check out the theory!

How is your optimal speed affected by Wind and McCready?


Use the slider to change wind speed and expected lift at the arrival in order to see how fast should you fly! Be sure to check out the theory first!!
Optimal air speed iskm/h (GPS speedkm/h) with a glide ration of !
