Flying the Tunnel -- System Engineering Tradeoffs Among Accuracy, Availability, Continuity, and Integrity for Category-l Precision Approach

Bruce DeCleene, Stephen Heppe

Abstract:	framework for designing navigation systems. This paper summ:uizes the tunnel concept, the parameters of Required Navigation Performance (RNP) associated with Category I precision approach, and the design issues and tradeoffs associated with local-area Differential GNSS Instrument Approach Systems supporting this type of operation. Mathematical relationships are derived in the following areas: (1) the tradeoffs among FIB, ground segment position fixing error and avionics position fting error, (2) navigation system performance versus availability: (3) navigation system performance versus continuity; and (4) data link performance versus continuity.
