Abstract
The discussion of expanding Satellite Voice Communications (SATVOICE) into the realm of Direct Controller - Pilot Communications (DCPC) and as a sole source of Long Range Communications Systems (LRCS) is evolving. Many shortcomings have been identified and specifications for new system development needs to resolve these shortcomings before SATVOICE can be approved as a substitute means of communication.
The limitations of current systems must be accounted for and the risks mitigated. The areas include Human Machine Interface (HMI), DCPC, ATC Vectoring, Call priorities, Satellite limitations, avionics limitations, flight plans, and Short Code implementation.
