RNAV utilizing capabilities in the horizontal plane only is called 2D RNAV, while RNAV, which also incorporates vertical guidance, is called 3D RNAV. Time navigation (TNAV) may be added to either 2D or 3D systems. TNAV added to a 3D system is called 4D. Acquisition Reform Interim Guidance Aeronautical Radio, Inc.

Availability

AVCS AVLN AVN AVR AVPAC AWIPS AWOP AWP

The availability of a navigation system is the ability of the system to provide the required function and performance at the initiation of the intended operation. Availability is an indication of the ability of the system to provide usable service within the specified coverage area. Signal availability is the percentage of time that navigational signals transmitted from external sources are available for use. Availability is a function of both the physical characteristics of the environment and the technical capabilities of the transmitter facilities.
