The ADTS554F Air Data Test Set is a portable four-channel flightline pitot static tester. It provides pitot static air data validation, leak testing, fault-finding and avionics instrumentation testing for any aircraft requiring angle of attack two off static-controlled channels, in addition to a pitot test channel. The ADTS554F can also be used as a standard two-channel, three-channel, or 2 independent two-channel flightline air data test set. Included is the ADTS Touch, a removable, robust wireless hand terminal that communicates to the test set via secure Bluetooth® wireless technology. This technology and the innovative design of the ADTS Touch remove the need to run cables or hoses into the cockpit.
