Why a Headwind Reduces Take-Off Distance: The Airspeed–Groundspeed Derivation
Why a Headwind Reduces Take-Off Distance: The Airspeed–Groundspeed Derivation Aeroplanes normally take off into wind because the wing must reach a required airspeed to produce lift, whereas the runway distance is travelled at groundspeed. A headwind contributes to the airspeed before the aircraft has covered any runway. It therefore reduces the groundspeed required at lift-off […]
How to Calculate Aircraft Take-Off Ground Run: A Flight Mechanics Tutorial
How to Calculate Aircraft Take-Off Ground Run: A Flight Mechanics Tutorial An aircraft does not become airborne simply because its engines are producing thrust. During the take-off ground run, thrust must overcome aerodynamic drag and rolling resistance. On a sloping runway, it must also overcome a component of the aircraft’s weight. This tutorial derives a […]
Types of Aircraft Drag Explained: Induced, Profile and Interference Drag
Types of Aircraft Drag Explained: Induced, Profile and Interference Drag An aircraft experiences several forms of aerodynamic drag at the same time. Some result from generating lift, some arise as air flows over the aircraft’s surfaces, and others are created when airflow around neighbouring components interacts. For a conventional aircraft in subsonic flight, total drag […]
