Application of T-Test Method in The High Temperature Test of Air Traffic Control Monitoring Equipment in Civil Aviation

Civil aviation ATC equipment needs to fully consider whether it meets environmental requirements before being put into operation. This article introduces the classification of air traffic control equipment and the different harsh environments to which various types of equipment will be subjected. It also introduces the details of the various effects of high temperature on the equipment. Then, taking the high temperature test of the secondary surveillance radar of the civil aviation ATC as an example, this article detailly introduces the test steps according to GB2423.2 for carrying out the high temperature test of this type of equipment. The receiver's dynamic range was tested during the test. After the test, the test results were calculated using the t-test method. Then, the calculated results are compared with the t-distribution critical value table to judge whether the equipment has passed the high temperature test.
