Crosstrack Error (XTK ERROR)
Displays present cross–track error from the desired LNAV course.
L or R indicates left or right of course.
Blank if error is greater than 99.9 nm.
Lateral RNP (Approach)
Displays the lowest applicable RNP for the approach.
Displays in large font for manually entered RNP.
Displays in small font for values provided by the navigation database.
Distance To Go
Displays the distance remaining to the next waypoint.
Glidepath
Displays the FMC computed glidepath for the approach.
Waypoint Speed/Altitude
Displays waypoint speed or altitude constraints in large font.
Displays FMC predicted values in small font when no restrictions have been
specified.
Vertical Deviation YA613 - YA687, YC153 - YD655
Displays present vertical deviation from the FMC computed glidepath.
Vertical Navigation Performance
Displays both the vertical RNP (Required Navigation Performance) and the
vertical ANP (Actual Navigation Performance) for the current leg.
Valid display range for vertical ANP is 0 to 999 feet.
Manual entries are allowed and are displayed in large font.
Valid entries are 10 to 999 feet and may be suffixed with an optional “/“
Entries are cleared at flight completion.
Values from the navigation database are displayed in small font.

N1 Limit Page
This section describes the in–flight version of the N1 LIMIT page. See the FMC
Preflight section for a description of the preflight version of the N1 LIMIT page.
Normally, N1 limits are automatically specified. Pilot selection of other limits is
allowed.
Pilot selection of a reduced climb mode does not change the automatic selection
for other phases of flight.
Pilot selected mode is automatically replaced by AUTO selection when the
autopilot next changes vertical mode.
The active thrust limit is used by the autopilot and is displayed on the thrust mode
display.
AUTO
Push – selects automatic computation of N1 limits for all phases of flight.
Go Around (GA)
Push – selects the go–around thrust limit.
Continuous (CON)
Push – selects the maximum continuous thrust limit.

Climb (CLB)
Push – changes the thrust mode from AUTO to the active climb thrust, i.e. CLB, CLB–1, or CLB–2.
Cruise (CRZ)
Push – selects the cruise thrust limit.
Reduced Climb (REDUCED–CLB)
Push – selects either of two reduced climb thrust modes.
CLB–1 provides a climb limit reduced by 3% N1 (approximately 10% thrust).
CLB–2 provides a climb limit reduced by 6% N1 (approximately 20% thrust).
The reduced climb N1 value is displayed on the CLB pages.
If either mode is <SEL>, deletion allows return to full rated climb thrust.
Any reduced climb selection is automatically deleted above 15,000 feet.
Note: If a reduced thrust takeoff has been specified on the TAKEOFF REF page, the FMC will re-compute CLB–1 and CLB–2 values as required to avoid a climb N1 value greater than the reduced thrust takeoff N1 value.
