Requesting GPS Approaches

T-6A INSTRUMENT NAVIGATION

CHAPTER EIGHT

RNAV procedures exist to the same runway, subsequent RNAV procedure titles will be "RNAV

(GPS) Z RWY 22,""RNAV (GPS) Y RWY 22," etc.)

Pilot/controller communications will not include the term "GPS" in describing an approach

procedure, but will utilize current phraseology (e.g., "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 the aircrew to utilize the LNAV MDA or circling minima.

WARNINGS

1. In no case will the aircrew utilize the GLS PA or

LNAV/VNAV decision altitudes. These are precision approach

minima and not authorized for the T-6A.

2. 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 stepdown 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.")
