The polar curve
0 viewsOct 7, 2026
Every speed has its own sink rate. Put the numbers on a graph and you get the polar, which shows the speed for climbing, the speed for distance and the glide at any speed, with an LS8's real numbers.
What you learn
- Explain sink rate and why it changes with speed
- Read minimum sink and its speed off a polar
- Find the best glide with the line from the origin
- Work out the glide ratio at any speed
- Recognise the back side of the curve
