flight director leveling guide

Abstract

The invention relates to the leveling guidance of a flight director. Methods, systems, and computer readable media for providing flight director guidance throughout a flare maneuver during landing maneuvers are described herein. The pre-flare flight path for the runway can be received and the flare entry altitude calculated. A flare command path may be calculated having a slope associated with a desired rate of descent at a desired touchdown location on the runway. An aircraft flare path may be calculated that transfers the aircraft from the flare entry altitude on the pre-flare flight path to the flare command path at the desired touchdown location. A flight director command to align the current flight path with the aircraft flare track may be provided during the flare maneuver.

Description

technical field [0001] This application relates to flight director flare guidance. Background technique [0002] Fixed-wing aircraft pilots typically strive to land the aircraft at very low sink rates. Doing so can reduce wear and tear on the aircraft, reduce maintenance costs, increase passenger comfort and satisfaction, and generally improve safety. To reduce the aircraft's sink rate during landing, pilots typically perform a flare maneuver before touchdown. The aircraft pitched up during the flare maneuver to reduce the sink rate to an acceptable level just before the main gear touched the runway. [0003] However, improperly executed flare maneuvers often result in landings farther from the runway than the desired touchdown zone. Landings that are too far from the runway may require increased use of brakes and thrust reversers, increasing maintenance and repair costs. Additionally, runway overruns typically occur several times a year because aircraft touch down witho...
