(2) It should be shown that the overpressurization devices, or the devices in conjunction with the tire inflation means permanently installed in the wheel, would not permit the tire pressure to reach an unsafe level regardless of the capacity of the inflation source.
(3) Both types of devices should normally be located within the structure of the wheel in positions that minimize the risk of damage or tampering during normal maintenance.
k. Compatibility. Compliance with § 25.735(k) may be achieved by the following:
(1) As part of the overall substantiation of safe and anomaly free operation, it is necessary to show that no unsafe conditions arise from incompatibilities between the brakes and brake system with other airplane systems and structures. Areas that should be explored include antiskid tuning, landing gear dynamics, tire type and size, brake combinations, brake characteristics, brake and landing gear vibrations, etc. Similarly, wheel and tire compatibility should be addressed. These issues should be readdressed when the equipment is modified.
(2) During brake qualification testing, sufficient dynamometer testing over the ranges of permissible brake wear states, energy levels, brake pressures, brake temperatures, and speeds should be undertaken to provide information necessary for systems integration.
