Potable navigation database

Abstract

The invention discloses a potable navigation database and belongs to the technical field of aviation software design and test. The potable navigation database comprises a waypoint information storageunit, an input unit, an index unit, an airway generation unit and an FMC interface, wherein the waypoint information storage unit is used for storing all waypoint information, and the waypoint information contains waypoint names and waypoint auxiliary information; the input unit is used for receiving a start waypoint name and a destination waypoint name inputted by a user; the index unit is used for providing output waypoints related to the input waypoints; the airway generation unit can determine an airway according to the waypoint information of the input waypoints and the output waypoints;the FMC interface is used for guiding the airway generated by the airway generation unit into an FMC. According to the potable navigation database disclosed by the invention, an airborne navigation database is independently designed; thus, convenience is brought to product integration testing personnel to test database software, airway data information can be completely guided out, and a testing accuracy rate is improved.

Description

technical field [0001] The invention belongs to the technical field of aviation software design and testing, and in particular relates to a portable navigation database. Background technique [0002] At present, civil aviation airliners basically adopt the FMS flight management system, which has a built-in navigation database and implements fully automatic navigation. The FMC receives the data information of each navigation system, combines it with the navigation database for comprehensive calculation, and uses the autopilot and auto-throttle systems to control the aircraft to fly from the departure airport to the airport with the best flight path, the best flight profile, and the most fuel-efficient way. destination airport. [0003] Existing navigation databases are generally provided regularly by specific companies such as Jeppeson chart publishing companies, packaged in DC-300 cassette tapes or other media, and distributed to airlines, and the data is loaded into FMC wi...

AI Technical Summary

Problems solved by technology

[0003] Existing navigation databases are generally provided regularly by specific companies such as Jeppeson chart publishing companies, packaged in DC-300 cassette tapes or other media, and distributed to airlines, and the data is loaded into FMC with a data loader every 28 days Among them, the navigation database brings inconvenience to the software testing of the database, which is specifically manifested in 1) product integration testers cannot accurately obtain the data of the installed product navigation database; 2) the navigation database is constantly being updated, which brings inconvenience to product testers ; 3) There is no module for effectively obtaining all navigation database data in installed products; 4) Limited navigation data is not conducive to random generation of route data, therefore, it is not conducive to testers to perform software testing
