Mission Computer B is way ahead of its class in the market in terms of Technology. It provides Voice & Text TX/RX via Satcom far beyond LOS. This enables Flight Following & Display at HQ. It provides integration of Radar TWS–AIS–ADS-B to present a “Situation Awareness” that is beyond any available Mission Computer today or in years to come. Caledonian re-introduced its Helicopter to Helicopter Relative Air Position "RAP" which was flown in 1987. This system offers the ability to display airborne traffic to participating helicopters with the minimum of aircraft modifications. Pilots can view the entire situation displayed at a glass cockpit display or over the radar display. Participating aircraft report Ident, Position, Speed & Trail. RAP is now ADS-B which is provided by Scorpio MCU-B.
