deep brakes vs rear risers

Recommended Posts

wind at your back you will want to put your canopy into minimun sink mode deep brakes. Wind coming at you from the front at a high speed you will want to use your front risers. Winds not as high rear risers may be the thing to do. Also don't forget about loosening your chest straps. Do minimal corrections, and lift your feet up. Of course every canopy is different, so you will have to find what works for your canopy

Great to see a polar posted on this forum – thanks Kallend!

Please correct me if I’m wrong but I believe that a big difference between a sailplane wing and a canopy however is that unlike a sailplane’s wing the shape of a canopy changes with different control inputs. Specifically, brakes distort the shape of a canopy where as rear risers change the overall angle of attack of the canopy but leave the shape more alone, i.e., flat. I assume that’s why in no wind conditions I can get a better L/D out of my Saber-2 170 with rear risers than with toggles. Of course, as has been pointed out, with a good tail wind it’s much more important to go for minimum sink which I seem to get by using full brakes.

P.S. – Perhaps just a tall tale, but I’ve been told that the “yaw string” was invented by one of the Wright brothers – the first airplane instrument.

Both distort a canopy. Rear risers tend to introduce a step in the center of the canopy, whereas brakes tend to deflect the back of a canopy. Note that the control surfaces of a sailplane wing are designed to do the same thing (i.e. distort the wing) but within the limitations of a rigid wing.
