REQUESTING GPS APPROACHES
Starting in February 2000, the FAA began the conversion of Published GPS approaches currently
titled "GPS RWY XX" to the new RNAV (Area Navigation) plate entitled "RNAV RWY XX."
Many aircraft, including the T-34C are not capable of conducting full RNAV precision
approaches. In order to provide full utilization to all operators who have the GPS capability, the
FAA has agreed to add "(GPS)" to the title of all RNAV procedures; e.g., "RNAV (GPS) RWY
XX." Where multiple RNAV procedures exist to the same runway, subsequent RNAV procedure
titles will be "RNAV (GPS) Z RWY 33,""RNAV (GPS) Y RWY 33," etc. (See Figures 7-17 and
Pilot/controller communications will not include the term "GPS" in describing an approach
procedure, but will utilize current phraseology; i.e.,"RNAV RWY 22," to describe these
procedures. Multiple procedures will utilize phonetic ATC phraseology; e.g., "RNAV ZULU
Runway 22." "RNAV YANKEE Runway 22." An ATC clearance for the RNAV procedure will
authorize a T-34C pilot to utilize the LNAV MDA or Circling minima.
In no case will pilots utilize the GLS PA or LNAV/VNAV
decision altitudes. These are precision approach minima and
not authorized for the T-34C.
During the interim period when existing GPS procedures are undergoing revision to the new title,
both "RNAV (GPS)" and "GPS" approach charts will be published. Note, however, existing GPS
procedures that incorporate a final approach step-down fix will not be included in the new naming
convention, but will continue to be published as separate approach procedures; e.g., "GPS RWY
SELECTING AND LOADING GPS NON-PRECISION APPROACHES
In order to use an approach, the approach must be loaded into the active flight plan. The APT 8
page is used to select approaches for the desired airport. The following example uses the VOR or
GPS 25R approach to Los Angeles International Airport (KLAX) with the ELMOO IAF.
The front unit must be on and functioning properly for either unit to
be used for navigation. The last input from either cockpit has
priority for system control.
