Problems solved by technology

After the go-around point is determined, if the go-around point is not decided after flying over this point, the aircraft may not have enough time to correct the deviation or cause the visual inspection to be too high, resulting in the aircraft colliding with the island surface or falling into the sea, resulting in the risk of landing on an island and a go-around accident
The traditional go-around decision-making method for island landing only takes the go-around point (a certain point in the flight space) as the only basis for the decision-making timing, and does not consider the particularity of the two natural environments of the aircraft passing through the sea and land during the go-around maneuver of the island landing. The amount of information is small; the traditional decision-making method does not analyze the change of the aircraft's own state during the transition from the normal flight state to the go-around state, and the analysis of decision-making influencing factors is relatively limited; therefore, the traditional decision-making method for island landing and go-around cannot complete a comprehensive and systematic decision-making

Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings. What this embodiment describes is a decision-making method for aircraft island landing and go-around:

[0028] 1. Establish a go-around track curve set

[0029] For a certain type of aircraft, a programmed go-around is performed on the simulator, and the initial state information of the go-around maneuver of the aircraft is recorded, including the flight position (x 0 ,y 0 ,z 0 ), where x 0 is the initial horizontal flight position of the aircraft, y 0 is the initial lateral flight position of the aircraft, z 0 is the initial vertical flight position of the aircraft, and the flight speed (v 0 ), the interference sinking rate and the flight path angle (γ 0 ), and store the flight data in the computer.

[0030] When the pilot receives the go-around command or decides to go-around, after a delay of 0.7s, he quickly pushes the throttle lever to execute the go-around...

Abstract

The invention relates to an aircraft islet landing wave-off decision method, comprising the following steps: (1) establishing a wave-off flight path curve set; (2) establishing a wave-off safety region Ssafe and a wave-off risk region Srisk; (3) comparing airplane position information with a wave-off envelope curve; and (4) judging whether the current region of an aircraft has a wave-off risk or not. The invention firstly designs the wave-off decision method applicable to special flight maneuvering of islet landing; the adaptability of the process is wide and the wave-off risk measurement can be carried out aiming at any flight position of the aircraft; and reasonable references are provided for the wave-off maneuvering safety of the emergency condition of an islet landing process, so as to have effective helps to pilots to relieve psychological pressure and improve the wave-off safety.

Description

technical field [0001] The invention relates to a decision-making method for an aircraft landing on an island and going around. Background technique [0002] As a flight maneuver under special circumstances, "island landing" is mainly used in military strikes, paratrooper training and survival rescue projects. Due to the complexity of the landing environment, it brings greater operational risks. When the pilot is about to land , if obstacles suddenly appear, weather visibility is too low, or the aircraft temporarily malfunctions, etc., you should take a go-around to avoid risks: increase the thrust to interrupt the landing, and return to the normal ascent state. [0003] When the pilot decides to perform a go-around operation, the situation changes suddenly from the approach and landing state to the stress and go-around, which will have a serious negative impact on the pilot's psychological and behavioral capabilities, which is similar to the stylized go-around on the simula...
