Crane Aerospace of Lynnwood, Wash., is developing an aircraft version of a handheld remote tire-pressure indicator that Goodyear developed for automobiles. SmartStem consists of a handheld digital readout device and a tiny, wireless pressure/temperature sensor embedded in the tire’s inflation valve or mounted on the wheels. The user aims the handheld unit at the sensor to obtain a readout of the air pressure, according to Crane. Tire temperature is also measured, enabling automatic correction to an equivalent standard temperature. Crane hopes to introduce SmartStem next year. Price is yet to be determined, but the sensor unit can be “easily” retrofitable in place of the regular inflation valve.
