N1 Limit Page

[Option - FMC U10.1 and later]

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.

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.

<ACT> STATUS LABEL

Identifies the active N1 thrust limit.

Displays the N1 for individual thrust limits based on present conditions and bleed

air configuration.

If CLB-1 or CLB-2 is selected, the N1% for CLB and the N1 cursors still display

values for full rated climb.

Chapter 11

FMC Cruise

Section 42

Introduction

The cruise phase automatically begins when the top of climb is reached.

During cruise, the primary FMC pages are:

• RTE LEGS

• PROGRESS

• CRZ.

The RTE LEGS pages are used to manage route restrictions and modify the route.

The PROGRESS pages display flight progress information. RTA requirements are

also specified on the PROGRESS pages. The CRZ pages display VNAV related

information. Other pages include:

• POS REF page - verifies the FMC position (refer to Section 40 of this

chapter)

• POS SHIFT page - permits selection of preferred position from list of

references

• RTE DATA page - displays progress data for each waypoint on the RTE

LEGS page. Displays wind data for cruise waypoints.

• REF NAV DATA page - displays information about waypoints, navaids,

airports, or runways

• LATERAL OFFSET page - permits selection of a route offset

• FIX INFO page - displays information about waypoints, and can be used

to create new waypoints and fixes

• SELECT DESIRED WAYPOINT page - permits selection of the desired

waypoint from a list of duplicate named waypoints

• NAV STATUS page - displays information about available navigation

aids.

The only cruise mode automatic page changes are the transition from climb to

cruise at the top of climb point and from cruise to descent at the top of descent

point.

LNAV Modifications

This section presents the normal techniques for modifying the route. The

modifications include:

• adding and deleting waypoints

• linking discontinuities

• resequencing waypoints

• intercepting a course.

11.42.1

Flight Management, Navigation -

FMC Cruise

Boeing 737 Operations Manual

RTE LEGS Page Modifications

When modifications are made to the RTE LEGS page, several automatic prompt

or identifying features assist in managing and executing the modifications, such

as:

• ERASE

• INTC CRS.

A waypoint can be added to the route whenever necessary.

The new waypoint must first be placed into the CDU scratchpad. Existing

waypoints can be copied from a RTE LEGS page into the scratchpad by pushing

the line select key adjacent to the desired waypoint.

The new waypoint is then inserted into the route at the desired sequence point by

pushing the line select key adjacent to the desired location for the new waypoint.

Using the NEXT PAGE/PREV PAGE function keys to select the desired location

does not alter the CDU scratchpad. The new entry automatically links to the

preceding waypoint via a direct route. Placing the new waypoint into the active

waypoint line is a special case and is discussed under Intercept Course in this

section.

All new waypoints, except along track waypoints, cause a route discontinuity

between the new waypoint and the following waypoint.

Note: If the FMC NAV database contains a HOLD pattern at the FAF, executing

a database approach with a procedure turn and then executing a HOLD at

the same FAF, using any inbound course, may cause a discontinuity

between the FAF and the procedure turn. If the discontinuity is removed,

LNAV guidance is available to fly the approach from the published holding

pattern. LNAV guidance is not available to fly the published procedure

turn.

Page Title

When the page is modified, MOD appears in front of the title in reverse

highlighting. This means the route is now altered. The MOD title also shows that

the modifications are not yet executed and can be removed using the ERASE

prompt.

Modified Waypoint

YKM waypoint is entered into the route between LAC01 and VAMPS. This

modification creates a route discontinuity.

Discontinuity Waypoint

Box prompts indicate the requirement to link the route by entering a route

waypoint into the discontinuity waypoint position.

ERASE

The ERASE prompt is displayed when the first modification is entered. The

prompt remains on the page until the modifications are erased or executed.

Selecting ERASE removes all modifications and restores all active data.

Discontinuity Header

Indicates that the route is not continuous. Distance to destination on the

PROGRESS page is not correct.
