Flight management system and method thereof based on multi-task parallel processing

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 andimprove 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...

AI Technical Summary

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

[0026] The electronic flight bag can reduce the voyage data of the cockpit paper printed matter, but in actual use, due to the variety and quantity of data files in the electronic bag, the call operation relationship is complicated, the efficiency of the human-machine interface is not as good as that of paper documents, and the effectiveness is very poor , which is also an inherent defect that it cannot achieve tight coupling with the airborne system
