Embodiment Construction
[0020] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0021] An aircraft airborne equipment testability verification index evaluation method, the specific steps are as follows:
[0022] 1) According to the FMEA report of the product, determine the failure mode set F of the product;
[0023] 2) Analyze all the failure modes in the failure mode set F of the product, and determine the failure mode sets that can be physically injected in the laboratory and the failure mode sets that cannot be physically injected;
[0024] 3) According to the failure mode determined in step 2) is all the failure mode sets that can be physically injected, then formulate the test plan, carry out the testability verification test, and complete the testability evaluation;
[0025] 4) According to the failure modes determined...
