The RA-4500 Radar Altimeter by Freeflight from Pacific Coast Avionics gives the aircraft pilot highly accurate altitude above-ground-level(AGL) information from 2,000 feet down to zero feet. This real-time altitude system offers an extra measure of operational safety during approaches and night operations. Its patented "anti-rotor-modulation" capability prevents altitude wandering while hovering in a helicopter or aircraft. The RA-4500 radar altimeter from Freeflight consists of a remote unit and dual antennas for incredible accuracy. The RA-4500 radar altimeter from Pacific Coast Avionics outputs allow seamless integration with other onboard equipment such as flight director systems. The RA-4500 may be purchased with the RAD-40 indicator.
