When required, VRNP values may be manually entered or displayed on RNP
PROGRESS page 4/5. The FMC will accept manual entry of a VRNP value
greater than the default value, but the VERIFY VERT RNP VALUE advisory
message will be displayed in the scratchpad. Manual entries are cleared at flight
completion.
Lateral Navigation (LNAV)
LNAV provides steering commands to the next waypoint. If selected, LNAV
engages when laterally within 3 nautical miles of the active route leg. If outside of
3 nautical miles of the active route leg, LNAV engages if on an intercept heading
of 90 degrees or less and the intercept will occur before the active waypoint. FMC
LNAV guidance normally provides geodetic paths between waypoints. However,
when an arrival or approach from the FMC database is entered into the active
route, the FMC can supply commands to fly a constant heading, track, or follow
an arc, as required by the procedure.
Waypoints
Waypoint (navigation fix) identifiers are displayed on the CDU and navigation
display.
