Requesting GPS Approaches - P-340

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

7-18.)

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.

WARNING

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

18."

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.

NOTE

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.
