Abstract

The invention relates to the field of flight system tests, and especially relates to a ground proximity alarm test system of an aircraft. The ground proximity alarm test system of the aircraft comprises an inertial navigation satellite combination system, an atmospheric engine system, a radio altimeter, a landing system, a terrain database for providing predetermined terrain data, an alarm system,and a ground proximity alarm computer for constructing a simulated aircraft, constructing a simulated terrain, controlling the simulated aircraft to perform a corresponding simulated flight or simulated landing, judging an alarm mode of the simulated aircraft, and transmitting an alarm instruction corresponding to the alarm mode or canceling the alarm instruction. The ground proximity alarm testsystem of the aircraft can perform simulation tests on ground proximity warning systems, so that the performance guarantee is high and the cost is low.

Description

technical field [0001] The invention relates to the field of flight system testing, in particular to an aircraft ground proximity warning testing system. Background technique [0002] Ground proximity warning system is one of the important components of aircraft flight safety. It can be based on excessive descent speed, excessive near-ground rate; too small flaps lowered during take-off or go-around climb; too low altitude; when the aircraft approaches, the glide path deviates downward; wind shear and other conditions provide the pilot with Provide a warning message. [0003] Therefore, it is particularly important to test the safety performance and stability of the ground proximity warning system; however, the current ground proximity warning system tests are all carried out on physical aircraft, and the safety performance guarantee is low and the cost is expensive. Contents of the invention [0004] The object of the present invention is to provide an aircraft ground p...
