This is the speed at which an aircraft gains the most altitude in a given horizontal distance, typically used to avoid a collision with an object a short distance away. By contrast, V Y is the indicated airspeed for best rate of climb, [ 2 ] a rate which allows the aircraft to climb to a specified altitude in the minimum amount of time ...
The speed at which the pilot begins to apply control inputs to cause the aircraft nose to pitch up, after which it will leave the ground. [7] [26] [Note 1] V rot: Used instead of V R (in discussions of the takeoff performance of military aircraft) to denote rotation speed in conjunction with the term V ref (refusal speed). [19] V Ref
It is rather a maneuver designed to show the pilot's proficiency in controlling the aircraft while performing a minimum radius climbing turn at a constant rate of turn (expressed usually in degrees per second) through a 180° change of heading, arriving at the new reciprocal heading at an airspeed in the "slow-flight" regime, very near the ...
In aviation, a variometer – also known as a rate of climb and descent indicator (RCDI), rate-of-climb indicator, vertical speed indicator (VSI), or vertical velocity indicator (VVI) – is one of the flight instruments in an aircraft used to inform the pilot of the rate of descent or climb. [1]
The rate of change of aircraft mass with distance is = =, where is the speed), so that = It follows that the range is obtained from the definite integral below, with t 1 {\displaystyle t_{1}} and t 2 {\displaystyle t_{2}} the start and finish times respectively and W 1 {\displaystyle W_{1}} and W 2 {\displaystyle W_{2}} the initial and final ...

The choice of which is the given first will depend on origin and period. A U.S. aircraft would have U.S. System of customary units given first (in the example of weight 'main' would be given in pounds (lb), and the value for 'alt' in kilograms (kg). Other aircraft are measured using the metric system, so they will have kg for 'main' and lb for ...
