| Abstract: | A scheme to test air\|borne equipments automatically was proposed based on VXI bus technology. The function and structure of the scheme were described by taking two common types of radio altimeters as examples. With introducing the key techniques involved in the scheme, an idea to improve the poor measurability of older radio altimeters by testing in different layers aided with hand tests was stressed. Finally, simulation tests were carried out to demonstrate the feasibility of the scheme, at a trouble locating rate of 85 pct and a trouble shooting rate of 60 pct for the altimeters. |
