Embodiment Construction

[0056] The present invention is based on the navigation performance allocation and monitoring method estimated by FTE, and the steps are as follows:

[0057] 1) Determine TSE from flight segment information;

[0058] 2) Determine whether the flight mode is manual mode;

[0059] Receive the flight mode information from the navigation exciter, and judge whether the current flight mode is the manual mode, if yes, go to step 3); otherwise, go to step 5);

[0060] 3) Calculate the FTE estimate in manual mode;

[0061] 4) Allocate the total system error requirement, go to step 7);

[0062] 5) Calculate the FTE estimate in automatic mode;

[0063] 6) Allocate total system error requirements;

[0064] Allocate the total system error requirement, go to step 7);

[0065] 7) Determine whether the current navigation accuracy meets the error requirement of the navigation system, if so, go to step 9); otherwise, go to step 8);

[0066] Receive the current navigation accuracy from the ...

Abstract

The invention relates to the field of airborne electronic system testing, provides a navigation performance distribution and monitoring method based on FTE estimation, and aims to set navigation parameter performance requirements of a navigation exciter according to a performance distribution method and monitor navigation parameter performance generated by the navigation exciter. Flight technical error fluctuation is estimated in a manual mode and an automatic mode, and the flight technical error is set more accurately by combining a method for setting a fixed flight technical error in an aviation industry standard according to a flight stage, a flight airspace type and a flight mode. Therefore, the performance requirement on the navigation system in the performance-based navigation is obtained; meanwhile, under the performance requirement, the performance of the navigation parameters is monitored. The method is mainly applied to airborne electronic system monitoring occasions.

Description

technical field [0001] The invention relates to the field of airborne electronic system testing, in particular to a navigation performance allocation and monitoring method based on flight technical error estimation. Background technique [0002] Performance-Based Navigation (PBN) is a new operational concept proposed by the International Civil Aviation Organization (ICAO) after integrating national Area Navigation (RNAV) and Required Performance Navigation (RNP). When an aircraft operates under the PBN flight procedure, its navigation system needs to meet the performance requirements such as total system error, integrity, availability, and continuity under the navigation specification corresponding to the flight segment. [0003] The navigation exciter simulates the navigation parameters during the flight of the aircraft, and can be used as the input for testing the onboard electronic systems such as the automatic flight control system and the navigation display. Traditiona...
