ARINC 429 Extends Compatibility With Leading EFIS Units

FreeFlight Systems, an international supplier of avionics systems for commercial and military aircraft, announced this week the introduction of the RA-4500, the latest addition to its TSO certified family of radar altimeters.

Like its predecessor, the RA-4000 that provides altitude over serial data links, the RA-4500 supplements its performance and functionality with an industry-standard ARINC 429 digital interface. Consisting of a remote unit and dual antennas for increased accuracy, the RA-4500 provides precise altitude above-ground-level (AGL) information from 0 to 2000 feet.

This real-time system is designed to enhance operational safety for pilots flying approaches, night time operations, and over irregular terrain.

"Since ARINC 429 is widely used in all types of aircraft, the RA-4500 Radar Altimeter provides an easy choice for pilots wanting enhanced situational awareness when flying close to the ground, but in a package that is affordable, reliable, and convenient to install," states Tim Taylor, president and chief executive officer, FreeFlight Systems. "The RA-4500 is designed to easily interface with many of the leading electronic flight instrument systems in the market today which eliminates a barrier to bringing this important safety enhancement to pilots," adds Robert Schneier, chief operating officer, FreeFlight Systems.

Including dual antennas, the RA-4500 system list price starts at $9,925, and is backed by a two-year warranty. In February 2009, FreeFlight Systems plans to introduce the RAD-40 Indicator which will be compatible with both the RA-4500 and the RA-4000.
