Atlantis DRA-707 Radio Altimeter Ramp Simulator

The Atlantis DRA-707 Radio Altimeter Ramp Simulator is designed to facilitate the testing of digital altimeters by providing simulated aircraft radio altitude information in a flight-line environment. Here are some key specifications:

  • Accuracy: Better than 0.1% in all parameters

  • Altitude Range: From -20 ft to +8,000 ft, with a resolution of 0.125 ft (BNR) and 0.1 ft (BCD)

  • Frequency: ARINC 429 Bus Frequency is variable, from 10 kHz to 15.9 kHz, selectable with a resolution of 0.1 kHz; default is 12.5 kHz

  • Ramp Rate Range: ±16,000 fpm with a resolution of 1 fpm

  • Output Channels: Can drive up to three radio altimeters, each having TTL and ARINC 429 outputs plus AFCS discrete


The machine will be sent away for UKAS calibration upon Purchase.


Comes with all relevant cables & manual.
