Typical glide angles with airbrakes deployed
James Thomson wrote:
Form drag is highly speed-dependent so speed affects the answer a lot. The Pegasus flight manual claims a glide angle of 5 with the airbrakes fully extended and an indicated speed of 49 knots. Given the history of the Pegasus design the ASW19 is probably fairly similar. The Pegasus flight behavior could not be more different (and far better) than the ASW19. [90 km/h = 49 knots is the minimum approach speed - personally I add a few!] -- Michel TALON
