All flight controls are manual. The helicopter is equipped with Honeywell dual KX175 navigation system
receivers and Honeywell (formerly Allied Signal) KR 85 automatic direction finder, night flying lighting,
attitude and directional gyroscopes and a rate climb indicator. An alternative avionics fit includes a
Rockwell Collins VHF-251/231 navigation receiver fitted with an IND-350 navigation indicator and an
ADF-650 automatic direction finder.
The communications system is based on a dual Honeywell KY195 transmitter / receiver and KT76
transponder or alternatively a Rockwell Collins VHF-251 and TDR-950 transceiver and transponder.
