RNAV/GPS approach procedures require GPS and can be selected for use. When an approach procedure
lists ‘
gps
’ after a NAVAID prefix, (such as ‘VOR
gps
17L’), this indicates the procedure is an Overlay Approach.
The procedure may be flown either as a conventional, ground-based approach procedure or may be flown
with the GPS.
Refer to the current, pertinent flight manual and regulations for information on alternatively using GPS
navigation for NAVAID exclusive approaches.
The system will allow the applicable level of service for the chosen approach using GPS navigation. See
the following table for approach service levels allowed by the system:
