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.
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 ...
At take-off, the fan displaces up to 1.3 t (2,900 lb) of air per second, the jet nozzle velocity is almost 1,000 mph (450 m/s) and each high pressure turbine blade generates around 800 hp (600 kW), rotating at 12,500 rpm with their tips reaching 1,200 mph (540 m/s). [6] Rolls-Royce reports the engine is 10 dB quieter than the Trent 700. [11]
The objective of the flight was to test the performance of the aircraft in simulated engine failures after takeoff, which meant throttling down one of the aircraft's engines to idle and switching off a hydraulic circuit. [6] During most of the tests, the aircraft's autopilot would be set to fly the plane to an altitude of 2,000 feet (610 m). [6]
A Takeoff Acceleration Monitoring System automates the pilot monitoring of Distance to Go (DTG), "to sense, in a timely fashion the development of insufficient acceleration, which would extend the takeoff roll, perhaps precipitously". [1] Over the years, recommendations have been made to develop a Take Off Performance Management System.
With a fuel fraction of nearly 85%, the GlobalFlyer could carry 5 times its weight in fuel.. In aerospace engineering, an aircraft's fuel fraction, fuel weight fraction, [1] or a spacecraft's propellant fraction, is the weight of the fuel or propellant divided by the gross take-off weight of the craft (including propellant): [2]
Brake to Vacate (BTV) is additional software planned by Airbus for incorporation on its line of airliners, intended to reduce runway overruns. A more tangible benefit is the increased ability to exit the runway at a specified turnoff point.
The maximum takeoff weight (MTOW) or maximum gross takeoff weight (MGTOW) or maximum takeoff mass (MTOM) of an aircraft, also known as the maximum structural takeoff weight or maximum structural takeoff mass, [1] is the maximum weight at which the pilot is allowed to attempt to take off, due to structural or other limits.
