% Compute glide angle, range and velocity.. Type Glide for a demo of a Cessna 172. In this example we add a parasitic drag cofficient of 0.21 to account for the fuselage. -------------------------------------------------------------------------- Form: [angle, v, r] = Glide( h, v, d, cL ) -------------------------------------------------------------------------- ------ Inputs ------ h (1,:) Altitude (m) v (1,:) Velocity (m/s) d (.)
