Pitot Static Tester / AoA TESTER
ADSE 744
-
This tester was specifically designed for the new-generation pitot tubes that integrate sensing probes, pressure sensors and powerful air data computer processing to provide all critical air data parameters including Pitot and static pressure, airspeed, altitude, and angle of attack. This Pitot Static tester is designed primarily for flightline use to cover the testing of all barometric and manometric pressure instrument systems. The AoA Channel behaves as a second Ps channel, in order to create a differential pressure between the 2 Ps Channel, allowing to performsimulations of different Angles of Attack. The large touch screen display, with on-screen help, enables all checks to be carried out easily on the flight deck or in the cockpit, by a single operator. The ADSE 744 is robust and housed in amobile weatherproof case. An attached bag contains the pressure hoses and electrical cables.
