Flight Test Evaluation of Airborne Tire Pressure Indicating Systems.
Abstract
Results of flight testing of seven different cockpit tire pressure indicating systems are reported with an evaluation of each concept and recommendations for final in-service testing. Six prototype systems were evaluated on two McDonnell Douglas DC-10's between October 1978 and January 1979. One system was tested by an airline on a DC-9 and the results are included in the report as an appendix. The systems evaluated included three analog tire pressure system concepts displaying actual fire pressure in the cockpit, two weight and balance systems measuring tire pressure indirectly via tire load and axle tilt, a go-no-go discrete pressure sensing system, and a wheel speed system that was change in rolling radius to detect a low tire. A detailed test evaluation is included for each of the systems, tested and comments on the general merits of each system type is included. A recommendation is made that each system be subjected to airline service test before entering fleet service.
