Avia 305 certification - Study guides, Class notes & Summaries

An airplane is towing a glider to altitude. The tow rope is 20° below the horizontal and has a tension force of 300 lb exerted on it by the airplane. Find the horizontal drag of the glider and the amount of lift that the rope is providing to the glider. Sin 20° = 0.342; cos 20 °= 0.940.Drag: Cos 20° = D/T (Rearrange) D = Cos 20° X Tension D = 0.940 X 300lbs D = 282lbs Lift: Sin 20° = L/T (Rearrange) Lift = Sin 20° X Tension Lift = 0.342 X 300 lbs
