Method for selecting alternate airport on flight route segment

Abstract

The invention discloses a method for selecting an alternate airport on a flight route segment. The method comprises the following steps: screening a plurality of candidate alternate airports based ona flight plan of a current route segment; dividing the plurality of candidate alternate airports into a return voyage area alternate airport and a to-be-flied area alternate airport; according to theflight parameters, the current position and the wind power parameters of the aircraft, and the position information and the wind power parameters of the candidate alternate airports, calculating the distances from the current position to the candidate alternate airports, the required flight duration and the fuel consumption; selecting an alternate airport with the shortest flight duration from thealternate airports in the return voyage area and the to-be-flied area; and providing related alternate airport information including flight duration and fuel consumption. According to the invention,the optimal alternate airport selection can be accurately and automatically selected, and enough visual and comprehensive prompts are provided for pilots, so that the pilots can easily make the optimal standby landing selection in a convenient and simple operation mode.

Description

technical field [0001] The present invention relates to an airborne flight management system (abbreviated as FMS) of an aircraft and its backup auxiliary function, in particular to a method for selecting a backup airport on a flight segment. Background technique [0002] The flight management system (FMS) is a system that can assist the crew to complete various tasks from takeoff to landing. It can manage, monitor and automatically operate the aircraft, and support the automatic flight of the aircraft throughout the range. The FMS can integrate sensor data on the aircraft to calculate the current position, speed, heading and other information of the aircraft to ensure that the aircraft flies stably on the route specified in the flight plan. The introduction of FMS can effectively reduce the workload of the crew, improve the automatic level of the aircraft, and ensure that the aircraft can optimally complete various flight tasks. In addition, the crew can use the FMS to modi...

Problems solved by technology

[0007] The technical problem to be solved by the present invention is to overcome the fact that the alternate landing assistance function of the flight management system in the prior art cannot accurately and automatically select the optimal alternate airport in time, and some parameters or information depend on the airline company’s advance setting or the pilot’s Due to the inconvenient operation and heavy workload of the pilot due to the manual input or operation, and the lack of intuitive and comprehensive prompt information given to the crew, a new method for selecting an alternate airport on the flight segment is proposed
