A tire pressure monitoring system (TPMS) is a means to electronically measure and report the current tire pressure. Some systems are capable of transmitting the information to the flight deck while other systems are for use on the ground by maintenance personnel (only). This SAE Aerospace Recommended Practice (ARP) document is intended to establish overall component and system function guidelines and minimum performance levels for a TPMS. The system should visually indicate the tire inflation pressure status. These guidelines include, but are not limited to:

1. a) Design recommendations for system components, which:
   1. 1 monitor tire inflation, and,
   2. 2 are located in/on the tire/wheel assembly, landing gear axle, and/or aircraft avionics compartment.
2. b) Recommended performance and safety guidelines for a TPMS.
