Foreword

RNAV Approach Procedures
Lateral Navigation/Vertical Navigation. RNAV non-
precision approach with vertical guidance.
Lateral Navigation. RNAV non-precision approach.
Lateral Navigation with Advisory Vertical
Guidance. RNAV non-precision LNAV approach
with advisory vertical guidance. The glidepath
is typically denoted by a light dashed line on
the vertical profile (Jeppeson only) with an
associated glidepath angle (usually in the 3.00
degree range) and is provided to assist the pilot
in maintaining a constant vertical glidepath,
similar to an ILS glideslope.
Localizer Performance with Vertical guidance
(LPV) approach.
RNAV precision approach.
LP indicates Localizer Performance with no
vertical guidance.
LP +V indicates Localizer Performance with
advisory vertical guidance. This annunciation
is available in software v6.00 and later. This
advisory guidance follows the same nature as
set by the LNAV +V as shown above.
