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.
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.
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 ]
An aircraft flight manual (AFM) is a paper book or electronic information set containing information required to operate an aircraft of certain type or particular aircraft of that type (each AFM is tailored for a specific aircraft, though aircraft of the same type naturally have very similar AFMs). The information within an AFM is also referred ...
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.

Takeoff weight is the weight of an aircraft as it takes off partway along a runway. Few flight planning systems calculate the actual takeoff weight; instead, the fuel used for taking off is counted as part of the fuel used for climbing up to the normal cruise height. Landing weight is the weight of an aircraft as it lands at the destination ...
