| RA-4000 Radar Altimeter PN 10-03976
For critical flight regimes, the new TSO-certified RA-4000 Radar Altimeter provides today’s pilots with highly accurate and reliable above-ground-level (AGL) information. This real-time system enhances operational safety during approaches, nighttime operations, and hazardous flight above rough terrain. One of our newest radar altimeters, the RA-4000 is especially valuable when flying search and rescue missions, forestry operations, pipeline maintenance, off shore helicopter ops, aero-medical emergency services, border patrol, and electronic news gathering operations. The RA-4000 Radar Altimeter is designed to be easily integrated with electronic flight information systems (EFIS), flight director systems, and terrain awareness and warning systems (TAWS), possessing serial inputs. Proven and precise, the RA-4000 offers improved situational awareness for a broad range of fixed and rotary wing aircraft. Designed for applications where accuracy is needed down to zero feet, such as helicopter and seaplane operations, the RA-4000 provides precise AGL information from 2000 feet down to ground level.
- Meets Precision Equipment output specification of TSO-C87
- RS-485/422 interface
- Software zero calibration
- Dual antennas for increased accuracy
- Lightweight, easy to install
- Flexible in aircraft placement
- Compatible with the RAD-40 Display
- Backed by the FreeFlight Systems two-year warranty
- Attractive pricing
RA-4500 Radar Altimeter PN 10-03977
For critical flight regimes, the new FreeFlight Systems RA-4500 Radar Altimeter (TSO-C87) provides today’s flight crews with dependable, highly accurate and economical above-ground-level (AGL) information. This real-time system enhances operational safety during approaches, nighttime operations, and hazardous flight above rough terrain. Our newest radar altimeter model, the RA-4500 is especially valuable when flying search and rescue missions, forestry operations, pipeline maintenance, off shore helicopter ops, helicopter emergency medical services (HEMS), other aero-medical emergency services, border patrol, and electronic news gathering operations. The RA-4500 Radar Altimeter with its ARINC 429 output can be easily coupled with modern electronic flight information systems (EFIS), flight director systems, and Terrain Awareness and Warning Systems (TAWS). Proven and precise, the RA-4500 offers improved situational awareness for a broad range of fixed and rotary wing aircraft. Designed for applications such as helicopter and seaplane operations where accuracy is needed down to zero feet, the RA-4500 provide precise AGL information from 2000 feet down to ground level.

RAD-40 Radar Altimeter Display
The RAD-40 Radar Altimeter Display (TSO-C87) is compatible with the FreeFlight Systems RA-4000 and RA-4500 Radar Altimeters. This panel-mount display provides critical AGL information to the pilot which is especially important when there are no visual clues to the landscape surrounding the airport or the flight path. The AGL information is displayed on a bright LED readout as reported from the RA-4000 or RA-4500 through a standard RS-422 serial interface. By simply turning the rotary knob on the front panel, the pilot is able to set a decision height (DH). When the preset altitude is reached, a DH LED is illuminated and a DH discrete output is set.
Moreover, the pilot is able to activate five trip-point discrete outputs (100-1000 ft.) to signal additional alerts to the flight management system or navigation management system if the aircraft descends through these altitudes. In addition to the standard version, a night vision goggle (NVG) compatible display is available. To simplify certain installations, a display mounted in a round faceplate adapter is also offered as an option.
