LP LP indicates Localizer Performance with
no vertical guidance.
LP +V LP +V indicates Localizer Performance

set by the LNAV +V as shown above.
NOTE: Advisory vertical guidance information displayed on the VDI in this mode is only an aid

the flight crew must use the primary barometric altimeter to ensure compliance with all alti-
tude restrictions in accordance with the LP or LNAV approach procedure.
