Takeoff and Landing Performance Assessment (TALPA) is a method used by airport operators to determine runway conditions for takeoff and landing. It produces a Field Condition report that allows pilots to assess braking action when the runway is not dry.
The takeoff decision speed V 1 is the fastest speed at which the pilot must take the first actions to reject the takeoff (e.g. reduce thrust, apply brakes, deploy speed brakes). At speeds below V 1 the aircraft can be brought to a halt before the end of the runway. At V 1 and above, the pilot should continue the takeoff even if an emergency is ...
The team then put those temperatures and headwinds into an aircraft takeoff performance calculator for a variety of different aircraft types, including the Airbus A320 – one of the most popular ...
The particular take-off distance required may be shorter than the available runway length. In this case a lower thrust may be used. Lower thrust settings increase engine life and reduce maintenance costs. The take-off thrust available from a civil engine is a constant value up to a particular ambient temperature.
A headwind will reduce the ground speed needed for takeoff, as there is a greater flow of air over the wings. Typical takeoff air speeds for jetliners are in the range of 240–285 km/h (130–154 kn; 149–177 mph). Light aircraft, such as a Cessna 150, take off at around 100 km/h (54 kn; 62 mph). Ultralights have even lower takeoff speeds.
In discussions of the takeoff performance of military aircraft, the term V ref stands for refusal speed. Refusal speed is the maximum speed during takeoff from which the air vehicle can stop within the available remaining runway length for a specified altitude, weight, and configuration. [ 19 ]
