Contexto
The evolution of GBAS will begin with an extension of the standards to enable operations to lower minima, ultimately to include CAT IIIB. The first step involves the implementation of multiple service types and an associated equipment classification scheme to ensure that future services are compatible with legacy GBAS avionics. New requirements will include enhanced monitoring in both the ground station and the avionics to meet CAT IIIB integrity requirements. A SARPs amendment introducing a new GBAS approach service type (GAST) intended to support CAT II/III operations has been developed and is currently undergoing operational validation.
The GBAS shall consist of a ground subsystem and an aircraft subsystem. The GBAS ground subsystem shall provide data and corrections for the GNSS ranging signals over a digital VHF data broadcast to the aircraft subsystem. The GRAS ground subsystem shall consist of one or more GBAS ground subsystems.
