DRA-707
Document Actions
The Atlantis DRA-707 radio altimeter test set facilitates testing of digital altimeters by providing simulated aircraft radio altitude information in a flight-line environment.
The DRA-707 test set:
- Accurately simulates descent, approach, flare, and touchdown,
- Can be used wherever active control of the radio altitude bus is a test requirement,
- Can be operated from any convenient location, but is compactly designed for use in the cockpit area.
Using operator-defined parameters such as start altitude, stop altitude, and vertical speed, the DRA-707 test set 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 following accessories are available:
- Various aircraft cables to support a variety of aircraft altimeters:
- Collins LRA-700 Cable - P/N: AY969-00298-001
- Collins LRA-700 Triplex Cable - P/N: 110-0440-101 * Collins LRA-700/900 Cable A310 Cockpit Cable - P/N: 110-0440-102

The DRA-707 test set 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.
