Embodiment Construction

[0039] The invention is realized through the design of the flight test scheme and the evaluation of the test effect.

[0040] The invention relates to a flight test method for search and positioning capability. The test recording equipment is installed on the test carrier aircraft to record the GPS data of the carrier aircraft in real time, search the system bus data, test the attitude information of the carrier aircraft, and test the GPS data of the ELT. Through the flight test, corresponding test flights are carried out on the search and positioning capability, search and positioning accuracy, and search and positioning distance. After the flight, through data processing, the search and positioning capability is analyzed, and the described search and positioning capability flight test method, its specific implementation steps are as follows:

[0041] Step 1. Aircraft test modification

Abstract

The invention relates to a flight test method for searching and positioning capability, and belongs to the field of test flight of avionics systems of civil aircrafts and transportation aircrafts. The method comprises the following steps: in a preset matching ELT emission signal coverage range, a test carrier aircraft performs radial flight from a station and to the station in sequence along any radial direction, and under the condition that all electronic and electrical equipment is turned on, the searching and positioning conditions are checked.

Description

technical field [0001] The invention relates to a flight test method for searching and positioning capabilities, and belongs to the field of test flight of civil aircraft and transport aircraft avionics systems. Background technique [0002] The search system is an important part of the water rescue mission system of large-scale fire extinguishing / water rescue amphibious aircraft. It forms the water rescue mission system together with the water landing rescue system and the airdrop rescue system, which can provide the required target location information for rescue personnel. Information such as environmental information and task execution status of the water rescue system. [0003] The search system is designed to meet the needs of maritime search and rescue missions. Compared with other maritime rescue units, the search system uses aircraft as a platform, and it is very convenient to search for specific targets. After a maritime accident, it can guide the rescue aircraft t...
