The performance data for landing an aircraft can be obtained from the aircraft's flight manual or pilot's operating handbook. It will state the distance required to bring the aircraft to a stop under ideal conditions, assuming the aircraft crosses the runway threshold at a height of 50 ft, at the correct speed.
The location of the reference datum is established by the manufacturer and is defined in the aircraft flight manual. The horizontal reference datum is an imaginary vertical plane or point, placed along the longitudinal axis of the aircraft, from which all horizontal distances are measured for weight and balance purposes.
In many flight dynamics applications, the Earth frame is assumed to be inertial with a flat x E,y E-plane, though the Earth frame can also be considered a spherical coordinate system with origin at the center of the Earth. The other two reference frames are body-fixed, with origins moving along with the aircraft, typically at the center of gravity.
The maximal total range is the maximum distance an aircraft can fly between takeoff and landing. Powered aircraft range is limited by the aviation fuel energy storage capacity (chemical or electrical) considering both weight and volume limits. [1] Unpowered aircraft range depends on factors such as cross-country speed and environmental conditions.
Few airplanes can operate with conventional takeoff and vertical landing (and its subtypes STOVL, CATOVL) as the F-35B. Horizontal takeoff and vertical landing ( HTVL ) in spaceflight has not been used, but has been proposed for some systems that use a two-stage to orbit launch system with a plane based first stage, and a capsule return vehicle.
Whereas, if an engine fails just below a high V 1, it will take more distance to stop, so the Accelerate Stop Distance Required is greater. [ 8 ] Alternatively, on runways longer than the balanced field length the pilot can use reduced thrust, resulting in the balanced field length again being equal to the runway length available.
A flight path parallel to and in the direction of the landing runway. It is offset from the runway and opposite the downwind leg. Crosswind leg. A short climbing flight path at right angles to the departure end of the runway. Downwind leg. A long level flight path parallel to but in the opposite direction of the landing runway.
The top of descent may be calculated manually as long as distance, air speed, and current altitude are known. This can be done by finding the difference between current altitude and desired altitude, dividing the result by the desired rate of descent , and then multiplying that figure by the quotient of the ground speed (not airspeed) and 60.
