Embodiment Construction

[0021] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0022] The method of the present invention is realized by the software of the ground proximity warning system, the ground proximity warning system is installed on the anti-submarine patrol aircraft, and is cross-linked with equipment such as the inertial navigation system, the atmospheric engine system, the radio altimeter on the aircraft, and receives the longitude and latitude information from the inertial navigation system, Receive radio altitude information from a radio altimeter. Attached below figure 1 , take a certain low-altitude anti-submarine patrol flight process as an example to illustrate the method of the present invention.

[0023] Step 1. The 101 Earth Proximity Warning System collects a set of latitude and longitude data (123.50E, 27.53N), and the radio altitude is 500m;

[0024] Step 2. 102 Compare the latitude and longitude ...

Abstract

The invention discloses a warning method in the field of aircraft ground proximity warning and particularly relates to an offshore mode warning method aiming at an anti-submarine patrol aircraft. The conditions of entering or exiting of an offshore mode are met or not is judged according to longitude, latitude and radio altitude; after information of meeting the conditions of the offshore mode is determined by crews, the upper limit of a warning envelope of a mode 4 is adjusted to 80m, i.e., the warning is not given when the warning envelope is not lower than 80m and the warning is given when the warning envelope is lower than 80m. According to the offshore mode warning method disclosed by the invention, the defect that a general ground proximity warning system sends mistaken warning when the anti-submarine patrol aircraft flies at the extreme low-altitude to execute an anti-submarine task is made up, disruptive mistaken warning during normal task execution is avoided, timely warning during abnormal flight is ensured, and the flight safety is ensured.

Description

technical field [0001] The invention relates to a warning method in the field of aircraft near-ground warning, in particular to an offshore mode warning method for an anti-submarine patrol aircraft flying at an ultra-low altitude on the sea surface. Background technique [0002] Controlled flight into terrain refers to the fact that the aircraft hits the ground, obstacles or water due to unknown terrain, unpredictable weather, or other mistakes when the aircraft does not have any mechanical failure and is operated by the crew normally. Accidents due to complex terrain. Controlled flight into terrain is one of the most important hazards in aviation. The equipment used to prevent controlled flight into terrain accidents is the ground proximity warning system. [0003] The working principle of the ground proximity warning system is to receive a variety of flight status parameters such as geographic location, flight altitude, attitude, heading, and speed, and use the built-in ...
