Problems solved by technology

[0025] It can be seen that due to objective conditions, the flight management systems of European and American countries maintain the current state, while the electronic flight bag technology cannot rely on the foundation of the flight management system to develop on its own, resulting in redundant resources, duplication of functions, and development costs for developers. Disadvantages such as high investment costs for users

Embodiment 1

[0093] Such as figure 1 As shown, a flight management system based on multi-task parallel processing, including:

[0094] electronic flight instrument system display for displaying the actual flight plan;

[0095]The multi-function control display unit is a multi-function control display unit used by the existing flight management system, through which, the flight management computing system can make and execute the flight plan function; it is used to control the flight management system unit An operating unit with its own display and keyboard, but with processing functions performed by the flight management system unit;

[0096] The flight management system processing unit is connected with the multi-function control display unit, and then, the flight management system processing unit is used to copy and formulate the flight plan, and evaluate and dynamically modify the flight plan;

[0097] A display with control keys is connected to the flight management system processing...

Embodiment 2

[0122] A flight management method based on multi-task parallel processing, comprising the following steps:

[0123] (1) After the pilot has made a flight plan through the multi-function display control unit (hereinafter referred to as the actual flight plan), copy the plan through the flight management system processing unit for evaluation purposes, for example, the copied flight plan Perform rehearsal analysis (hereinafter referred to as evaluation flight plan).

[0124] (2) Evaluate the flight plan. The evaluation flight includes two methods:

[0125] A. Parallel with the actual flight plan, called "synchronous evaluation method". Because the flight management system cannot be directly modified when controlling the aircraft, otherwise it may cause errors. Through the parallel and synchronous evaluation method, a tool for modifying and rehearsing the effect is provided for the flight personnel, so as to scientifically evaluate the basis for the proposed modification. That ...

Abstract

The invention relates to flight management system and method thereof based on multi-task parallel processing. The system comprises an electronic flight instrument system display unit, a multifunctional control display unit, a flight management system processing unit and a display unit with a control button, wherein the multifunctional control display unit is used for maintaining existing functions of formulating and executing a flight plan; and the flight management system processing unit is connected with the multifunction control display unit and used for copying the formulated flight plan and carrying out assessment and dynamic modification on the flight plan. The invention converts the traditional signal processing scheme into a parallel processing scheme: one processing scheme is used for maintaining the traditional functions of formulating and executing the flight plan, and the other processing scheme is used for providing the dynamic modification and assessment functions; and flight personnel can effectively prepare and scientifically assess the change basis by dynamically modifying an assessment scheme, therefore, the invention can satisfy the changeful practical needs and improve the flight safety and the flight operation effectiveness.

Description

technical field [0001] The invention belongs to the technical field of civil aircraft flight control, navigation, guidance and human-computer interaction, and in particular relates to a civil aircraft flight management system and method thereof. Background technique [0002] The flight management system is the top manager in the automated flight system of civil aircraft. It generates a flight plan according to the input of the flight personnel by using the parameters of the aircraft performance and navigation database built in the flight management system; through the cross-linking with the automatic control, automatic throttle and flight display system, the automatic flight function is realized, and the guidance is completed. Flight Plan. [0003] Like other avionics systems, flight management systems need to pass the airworthiness certification process before they can be installed on civil aviation aircraft. Civil aviation airworthiness certification standards are mainly...
