  • Pitot-static air data test system with automatic dependent surveillance-broadcast (ADS-B) verification
    Patent number: 10301042
    Abstract: A system for verifying an aircraft instrumentation value comprising: an Air Data Test Module (ADTM) configured to pneumatically simulate at least one instrumentation value based upon a pressure set-point. The pneumatically simulated instrumentation value corresponds to the pressure set point and is reported by an aircraft transponder. A receiver module receives the pneumatically simulated instrumentation value transmitted by the aircraft transponder. A signal processor, is operative to (i) control the ADTM, (ii) command a prescribed instrumentation value to be simulated by the ADTM, (iii) compare the prescribed instrumentation value to the pneumatically simulated instrumentation value, and (iv) issue a pass signal when the values match, and a fail signal when the values differ by a threshold value.
