If the navaid has failed, FAIL will be displayed in small font.

If there is no corresponding identifier for the displayed frequency, then the

identifier field will be blank and only the frequency will be displayed.

On lines 1L or 1R, for VOR/ILS displays, the mode of tuning will be shown:

• M - Manual

• P - Procedural

• A - Automatic.

On lines 2L - 2R through 4L - 4R, if no DME information is received then the

identifier and frequency field is blank.

IRS Status Display

FMC Cruise

Boeing 737 Operations Manual

Navigation Options (NAV OPTIONS)

The FMC normally rejects the use of navaids that are not suitable for navigation.

However, when the aircrew is aware that unreliable navaids exist (either by

NOTAM, ATC, etc.) they should manually exclude these navaids from the FMCs

navigation solution. This will prevent the possibility of incorrect position

calculations and maximize the FMCs reliability. This is accomplished through the

NAV OPTIONS page.

Access to the NAV OPTIONS page may be gained by selecting the NAV

OPTIONS prompt on the REF NAV DATA page or by selecting NEXT or PREV

PAGE on the NAV STATUS page.

DME/VOR INHIBIT

Enter the identifier of up to two VOR/DME, VORTAC, or DME stations that must

not be used for FMC position updates.

Entries are blanked at flight completion.

Deleting or overwriting removes a previous inhibit.

The FMC normally uses DME from two different ground stations to update its

position solution. When two DME stations are not available, the FMC reverts to

single station radial-DME updating to determine position. Only two of the four

inhibit entries are utilized at any one time depending upon which update mode the

FMC is operating in. The DME INHIBIT entries are excluded from the FMCs

update solution whenever the FMC is updating from two DME stations. The VOR

INHIBIT entries are excluded from the FMCs update solution whenever the FMC

is radial-DME updating.

Valid entries are airports, navaids, and waypoints from the navigation database.

Valid entries are airports, navaids, waypoints or runway identifiers from the

navigation database.

The selected fix is displayed on the navigation display map mode and highlighted

by a green circle.

Distance Entry

Enter a distance from the fix. Distances from the fix are displayed on the

navigation display map mode as a dashed green circle around the fix.

11.42.54

Flight Management, Navigation -

FMC Cruise

Boeing 737 Operations Manual

When the distance intersects the active route, the ETA, DTG, and predicted

altitude at the intersection are displayed for that intersection.

If there is more than one intersection, the data will apply to the first occurrence

and will sequence as each intersection is passed.

Valid entries are xxx.x:

• leading zeros can be omitted for distance

• decimal values can be omitted

• distance only entries must start with a /.

ETA - displays the estimated time of arrival to the intersection point.

DTG - displays the distance to go to the intersection point.

ALT - displays the predicted altitude at the intersection point.

Radial Entry

Enter a radial from the fix. Radials are displayed on the navigation display map

mode as green dashed lines from the fix.

When the radial intersects the active route, the ETA, DTG, and predicted altitude

at the intersection are displayed.

If there is more than one intersection, the data will apply to the first occurrence

and will sequence as each intersection is passed.

Valid entries are xxx.

Radial/Distance Entry

Enter a radial, distance, or both radial and distance from the fix. A radial and

distance from the fix is displayed on the navigation display map mode by both

radial and distance, but ETA and ALT fields will be blank.

ABEAM

Displays the abeam point and calculates the ETA, DTG, and ALT information.

The fix abeam point ahead of the airplane is displayed by a radial line from the

waypoint ending at the nearest perpendicular route leg intersection.

If there is more than one intersection, the data will apply to the first occurrence

and will sequence as each intersection is passed.

Route Intersection Point Copied

Pushing the line select key for one of the RAD/DIS entries copies the fix

place/bearing/distance definition into the scratchpad. This fix can be placed into

the route on a LEGS page as a waypoint.

Chapter 11

FMC Descent and Approach

Section 43

Introduction

The descent phase begins at the top of descent point and continues to the end of

descent point. Planning for the descent phase begins during cruise.

The approach phase begins at the end of descent point and continues to touchdown

or go-around. When a go-around is accomplished, the FMC enters the cruise

phase.

The only automatic page change provided in the descent/approach modes is the

transition from cruise to descent at the top of descent.

Early Descent

Early descent may be commenced prior to reaching the top of descent by using the

DES NOW prompt.

Descent

During descent, LNAV progress is managed using the RTE LEGS and

PROGRESS pages, as in the cruise phase. VNAV descent management is

accomplished primarily on the DES page.

The DES FORECASTS page is also available to enter forecast wind data to aid in

descent planning.

[Option - With alternate destination prediction]

Other pages which support descent are:

• DES FORECASTS page - to enter forecast wind data to aid descent

planning

• ALTERNATE DESTS page - to manage the selection of alternate airports

and diversions.

Descent Page (During Cruise)

The descent page is used to monitor, revise, or select the descent path. Descent

modes are economy (ECON) path or speed and manual path or speed. The default

VNAV descent mode is ECON PATH. The crew must select a manual speed

descent mode.

The page title reflects the VNAV descent mode. The path mode controls descent

to fly a vertical path which complies with altitude and speed restrictions in the

flight plan. The speed mode controls descent at a fixed speed and complies with

altitude and speed restrictions in the flight plan.
