Altimeter tester DRA-707

aeronautical

The Atlantis Avionics DRA-707 Digital Radio Altimeter Test Set is designed to facilitate testing of digital altimeters by providing simulated aircraft radio altitude information in a flight-line environment. Using operator-defined parameters such as start altitude, stop altitude, and vertical speed, the DRA-707 defines a radio altitude ramp. This information, along with error and fault control information, is transmitted in digital form to drive the radio altitude buses of up to three aircraft altimeters.The DRA-707 is connected to the front of the aircraft’s altimeter by a cable adapter and accurately simulates descent, approach, flare, and touchdown. The DRA-707 may be used whenever active control of the radio altitude bus is a test requirement. It may be operated from any convenient location, but is designed to be used in the cockpit area.The following accessories are available: Various aircraft cables to support a variety of aircraft altimeters. Fifty-foot extension cable. Remote control unit.The DRA-707 is housed in a portable, weather-resistant case. The lower portion of the case houses the electronics and the detachable upper part of the case provides storage space for cables and manuals. The principal electronic circuits are attached to the front panel, which is easily removed for maintenance. All printed circuit assemblies are designed to allow convenient removal and replacement using standard electronic shop tools.
