In flight mechanics, the term “glide” refers to a controlled descent of an aircraft without the use of engine power. During a glide, an aircraft’s engines are typically either shut down or set to idle, and the aircraft relies on its aerodynamic properties to maintain forward motion and generate lift.
R = (h * Cl / Cd)
R = Glide Ratio (L/D Ratio) h = Altitude Cl = Lift Coefficient Cd = Drag Coefficient
