Gliding - airbrakes in final turn
Have been told this is a bad idea, following my first flight in a Discus where I cracked them open as I was turning final
Have been thinking about it since and not sure the reasons why? Is it something to do with the inside wing flying closer to stall speed and so a sudden loss of lift (area) could cause it to stall? But then given the high approach speed I would imagine this is less likely
Is it the same on all glider types?
