PREFACE

Several updated versions of the FMCS are currently in service.This guide covers the Update 10.0 through 10.3 versions of theFMC flight software, and Update 2 of the LCDCDU flight software.Part 1 of this guide contains an introduction to the FMCS with someexplanations of the concepts behind what it does.Part 2 explains normal operation and is broken down into systemprompts and usage hints, a quick reference checklist, and a de-tailed operation description. The quick reference checklist is ar-ranged by phase of flight over a U.S. route from Chicago to St.Louis. The detailed operation description covers the CDU display,keys, and annunciators, and explains system operation for a normalflight with AFDS and A/T integration. The detailed operation de-scription is arranged by phase of flight over an example route be-tween London, England, and Frankfurt, Germany.Part 3 covers non-normal operation such as power loss, sensorfailure, and alert and advisory messages.Part 4 consists of a detailed system description and a design sum-mary. The sequence of operations for a typical flight profile isshown on pages 443 through 454.Update 10.0 combines the operational characteristics of Update 7.4and Update 8.4 series into a single software program, with the Up-date 8 features now enabled and disabled via the Software Optionscodes. The SW OPTIONS page has been added to provide aconvenient display of the enabled options available to the aircrew.In addition to the Update 7.4 and Update 8.4 operational character-istics, Update 10.0 includes the following features: Enhanced File System Download recording capability. VNAV operation with failed Fuel Summation Unit. SELECT DESIRED WPT page expanded to two pages (12

waypoints maximum). Waypoints are listed in order of increas-ing distance from the reference point, and include the navaidtype in the header.

Make use of the OVERFLY flag in the NDB to determine if aforced overfly of the runway waypoint is required prior to se-quencing to lateral guidance to the missed approach.

The ENG OUT mode is advisory only and can no longer beexecuted, eliminating the loss of VNAV guidance.

Added 150 Knots Speed Constraint Restriction to all Final Ap-proach Fix points for all approach types.

The default Software Options Code is changed to enable themanual RNP option.

Revision 1 xviii TDM 2024

The software is compatible with the year 2000 rollover of theNDB.

Improved navigation accuracy. Improved ANP calculations. Replaced spherical earth model with WGS84 Earth Model. Improved NDB latitude and longitude resolution to 6 feet. Updated magnetic variation model (program pin dependent

on 737300/400/500 aircraft). Incorporates fixed radius turn legs to allow any geographic

point to be used as the turn center for enroute legs, legs inSIDs and STARs, and approaches.

Incorporates DME Arc radius turn legs to allow any DME to beused as the turn center for legs in SIDs, STARs, and ap-proaches.

RNP values for each leg are stored in the NDB. Selection of an approach when multiple approaches of the

same type exist. Allows LNAV control at takeoff (Dual FMS only).

NOTE: Requires Autopilot modification in 737300/400/500aircraft.

Allows VNAV controlled descents below the MCP altitude.NOTE: Requires Autopilot modification in 737300/400/500

aircraft. Added RTA AT/BEFORE and AT/AFTER windows. Changed the prompt CAPTURE to DESCEND NOW. Reduction in the number of DISCOs.

Provide more tolerant bypasses. Allow for path overshoot in adverse wind conditions. Climb speed restrictions as low as 100 kts may be manually

entered. T h e f o l l o w i n g f e a t u r e s w e r e a d d e d t o s u p p o r t t h e

737600/700/800 (new generation) aircraft: Loadable Performance Data Base. First Principles Takeoff Speeds (FPTOS) calculations are

incorporated. VREFbased flaps maneuver speeds replaced fixed GW in-

crement flap block speeds.

Revision 1 xix TDM 2024

The primary purpose for Update 10.1 is to add operational capabili-ty for the 737800 aircraft. In addition, this update provides in-creased compatibility between 737300/400/500/700/800 aircraftwith the Boeing 1062225003 (SI Model 2907A4) FMC installed.Update 10.1 includes the following features: THRUST BUMP FEATURE The Thrust Bump feature has

been added to allow the air crew to select (bump to) the nexthigher engine thrust rating when more output is desired foroperational reasons. The Thrust Bump selection is made onthe N1 LIMITS page. This feature is initially available for useon all 737800 models. The Thrust Bump selection may alsobe uploaded via the ACARS function.

TAKEOFF REF AND N1 LIMITS PAGE CHANGES TheTAKEOFF REF and N1 LIMITS pages have been modified toaccommodate the Thrust Bump feature and to provide com-monality among Boeing aircraft. Several display items havebeen relocated between the TAKEOFF REF pages and theN1 LIMITS page. In addition, the following new features andchanges have been included: WET SKID RESISTANT Runway FEATURE The WET

SKID Resistant (SKR) runway condition feature has beenadded to the TAKEOFF REF page. SKR is selectable justas the WET and DRY conditions and is functional for all737600/700/800 aircraft.

The TAKEOFF SPEEDS DELETED message is displayedindependently of the ACARS function When the activedeparture runway, runway wind, runway slope, runwayheading, takeoff flaps, runway condition, takeoff outside airtemperature, selected temperature, or engine thrust ratingare changed, the TAKEOFF SPEEDS DELETE messagewill be displayed in the scratch pad for all 737600/700/800aircraft.

DEFAULT FLAPS VALUE A default flaps value is no lon-ger required. If a valid flaps default value does not exist,the TAKEOFF REF page will display BOX prompts to alertthe air crew that flaps data is a required entry.

NOTE: Refer to the TAKEOFF REF and N1 LIMITS pages forthe changes listed above.

DEFAULT NAVIGATION DATA BASE SIZE The default sizeof the Navigation Data Base (NDB) has been changed from256K bytes to 1M bytes.

USE OF NDB RUNWAY OVERFLY INDICATOR An OVER-FLY indicator is contained in the NDB to adjust MISSED AP-PROACH sequencing. If the OVERFLY indicator is set, then

Revision 2 xx TDM 2024

the runway must be flown over prior to sequencing the missedapproach. If the OVERFLY indicator in the NDB is not set, later-al guidance will be provided direct to the missed approach onceactive.

The primary purpose for Update 10.2 is to add operational capabili-ty for the 737600 aircraft. In addition, this update provides in-creased compatibility between 737300/400/500/600/700/800 air-craft with the Boeing 1062225003 (SI Model 2907A4) FMCinstalled.UPDATE 10.2 is replaced by UPDATE 10.2A:UPDATE 10.2A includes the following features: Addition of Color to FMS Displays for the LCD CDU The

FMS software has been updated to make use of color displayswhen the new Smiths Industries Model 2584A series LCD CDUis installed. The new LCD CDU is being introduced as stan-dard production fit for 737 deliveries and is a form/fit/functionreplacement for the existing SI Model 2577 series CathodeRay Tube based CDUs. Section 2 provides a description ofthe color guidelines currently incorporated.

High Altitude Maneuvering A bank angle limiting algorithmhas been added for high altitude and high weight conditions.Prior to this update, bank angle limit was set at 25 degrees formost turns, even at high altitudes. With this update, the turnswill be limited to the computed bank angle which can beachieved for the current weight and altitude condition of theairplane. The new computed limit may vary between 5 and 25degrees based on weight and altitude.

Updated Altitude Mismatch logic for Approaches and Transi-tions When encountering two differing altitudes at the samepoint for the last segment of an approach transition and thefirst leg of the final approach, this change ensures use of themore conservative of the two altitudes encountered in the Navi-gation Data Base. This also applies to STARs and STARstransitions.

Inhibit Runway Offset Updates when GPS Data is Valid Thischange inhibits the operator from performing manual runwayoffset updates when the FMS is receiving valid GPS data.

Add LDA, SDF, and IGS Approaches The use of LocalizerDirectional Aid (LDA), Simplified Directional Facility (SDF), andInstrument Guidance System (IGS) approach types have beenadded to the software.

Add Quadrant/Radial and Altitude on the Hold Page Thischange supports addition of a Quad/Radial field to the HOLDpage to allow direct entry of holding quadrant and radial in ATC

Revision 2 xxi TDM 2024

clearance language. The radial is the reciprocal of the inboundcourse, except for the special case of a hold placed on a placebearing distance (PBD) waypoint from a VHF Navaid. An alti-tude field is also added to the HOLD page which is a duplicate ofthe altitude field opposite the hold at waypoint on the LEGSpage.

NOTE: Refer to the HOLD page. Navigation Data Base Size The default size of the Navigation

Data Base size has been increased from 1 Megawords to 2.5Megawords.

UPDATE 10.3 includes the following features: RTE Page the following changes and added capability have

been made to the ROUTE pages: RTE Page 1 now contains airport data and prompts only.

Procedure data, Airways data, and Enroute data are nowdisplayed beginning on page 2.

Flight Plan data is increased from 100 waypoints to 150waypoints.

The Supplemental Waypoint database is increased from 20waypoints to 40 waypoints.

EngineOut Advisory the ENG OUT page is now a referenceoriented page. Selection of the ENG OUT prompt on theCLIMB or CRUISE page will not cause a change to the verticalpath construction.

Polar Navigation navigation capability added to allow flightsover the earths poles: Added GPS Track data to the PROGRESS page to provide

aircraft heading data at the poles if both IRUs fail. GPS position is used as the center point on the EFIS POS

SHIFT display if both IRUs fail. Multiple Localizer Approaches To Same Runway the Naviga-

tion Database may now contain more than one localizer ap-proach to the same runway, and are crew selectable at theCDU.

PROGRESS Page changes to the PROGRESS page are asfollows: GPS Track data added for polar navigation. Lateral Steering Crosstrack data is expanded to include a

one hundredths digit position. The Lateral Steering Cross-track now references the lateral path instead of the straightleg segments.

LEGS page The Vertical Angle display data is expanded toinclude a one hundredths digit position.

Revision 3 xxii TDM 2024

VNAV Disengagement During RNP Operations during RNPoperations, VNAV may now remain engaged within the allow-able 2 X RNP Crosstrack Deviation window, or when LNAV isengaged.

Takeoff To Climb Transition the FMS now automatically tran-sitions to the CLB page when on the TAKEOFF REF page andweight goes off wheels

Block Operating Speeds (737300, 400, 500) programmedblock operating speeds for these aircraft have been increasedas follows:

FLAPSPOSITION

138.5 KLBS

5 Deg 180 KTS 190 KTS 200 KTS10 Deg 170 KTS 180 KTS 190 KTS

Alternate Navigation GPS Alternate Navigation capabilityadded which allows the FMC to transmit up to 60 waypoints ofthe current active flight plan to the CDU for alternate naviga-tion operation (function is currently unique to the Boeing busi-ness Jet using the SI LCD CDU with Update 2 OperationalProgram loaded).

Message Change The IRS NAV ONLY message is eliminatedand the UNABLE REQD NAV PERFRNP message is dis-played when ANP exceeds RNP for the specified delay time.

FMC RNP Approach Operations VNAV will no longer be dis-connected at the GSI point unless the FCC G/S Mode isarmed.

CLB N1 Display CLB N1 Limit values are now displayed aswell as Derate CLB N1 values. On previous updates, only theDerate CLB N1 values were displayed.

EFIS Mapping During Missed approach the runway symbolon the EFIS map remains displayed during a missed approachoperation, even after it has been sequenced.

PERF INIT Page Planned Fuel values are now retained dur-ing the test on the ECS packs.

Pilot Defined Company Routes Option enables the user to: Load the Flight Plan Navigation Database (FPND) from disk

using the Flightstar software, and retrieve any routes andwaypoints stored in the FPND while onboard the aircraft.

Save up to 10 routes in a Supplemental database using theCDU onboard the aircraft. The saved routes are retainedby the FMS until manually deleted. Terminal procedures,

Revision 3 xxiii TDM 2024

airways, and user defined waypoints can be saved. Certainrestrictions apply; manually entered HOLDs and Altitude/Speed Restrictions are not retained.

Allows the Enroute portion of a flight plan displayed on theCDU to be reversed. This creates a MOD flight plan withthe Origin and Destination points reversed along with anyairways and enroute waypoints. Certain restrictions apply;terminal procedures, manually entered HOLDs, and Altitude/Speed Restrictions are not retained.

Geometric Path Descent Option allows flying along a com-puted gradient path from one altitude restriction to the nextduring DESCENT. The NDB Gradient may be maintained viaedits on the CDU, including inserting waypoints and deletingaltitude restrictions on the gradient legs.

Quiet Climb Option supports noise abatement proceduresduring Climb phase by providing a quiet climb cutback N1 tar-get between a preprogrammed thrust reduction altitude andthe restoration altitude. The default thrust reduction and resto-ration altitudes are provided in the Model/Engine Database(MEDB) and may be changed through the Loadable Perfor-mance Defaults Database (LDDB), manually changed at theCDU, or uplinked via ACARS.

ENGOUT SIDs Option provides a display of the StandardInstrument Departures (SIDs) from the NDB that are tailoredfor Engine Out (EO) operation. EO SIDs may be selectedfrom the DEPARTURES page. In some instances, the EOSIDs are automatically inserted into the flight plan when certaincriteria are met.

UPDATE 10.4 includes the following features: Model 2907C1 & 2907A4 FMC Compatibility Update 10.4

software is compatible with the existing Model 2907A4 FMCand the new Model 2907C1 FMC.

Increases Nav Data Base Size to 3.5 MegaWords softwarereallocates memory usage to expand the Navigation DataBase Size to 3.5 MegaWords for either the Model 2907A4FMC or new Model 2907C1 FMC Computer. The previous sizesupported by Update 10.3 was 2.5 MegaWords.

Increase Model/Engine Data Base Size to 1.5 MegaWords software reallocates memory usage to expand the Model/En-gine Data Base Size to 1.5 MegaWords for either the Model2907A4 FMC or new Model 2907C1 FMC Computer. The pre-vious size supported by Update 10.3 was 1.0 MegaWord.

Display VNAV Disconnect Message if A/P Disconnects duringApproach the VNAV DISCONNECT message is displayed if

Revision 3 xxiv TDM 2024

VNAV is valid, VNAV becomes disengaged, and the under-speed flag is set on approach.

When XTK exceeds RNP for idle descent legs and computedgradient legs, VNAV will remain in Path Mode versus switchingto Speed Mode.

When exiting speed intervention during descent, VNAV willswitch to Path Mode if it is not already the active mode.

Resize Hold Pattern for Descent Altitudes includes the abilityto size and resize a hold pattern with a default leg time basedupon the altitude of the hold fix waypoint. The hold pattern legtime is based on the predicted altitude of the hold fix waypointuntil the hold entry waypoint becomes the goto waypoint andlateral guidance is doing a final update on the reference pathbuffer. At this point the resize logic will use system altitude toresize leg time. Climbing or descending through the altitudethreshold of 14,200 feet will be the trigger for determiningwhether the leg time will be 1.0 min. or 1.5 min.

NOTE: The leg length will only be resized if leg time or leglength have not been manually entered on the holdpage.

HOLD EXIT Prompt Improvements includes the ability to dis-play a HOLD EXIT prompt after an inhold edit has been exe-cuted. The execution of an INHOLD edit results in the cre-ation of a new hold. The title, ACT HOLD is displayed on theHOLD page, even though the aircraft has not yet entered thenew hold pattern. The HOLD EXIT prompt is made availablebefore the new hold is actually entered. Subsequent selectionof the HOLD EXIT prompt will delete the new hold.

ALT CONSTRAINT XXXXX Message Improvements when aFlight Plan edit results in an altitude conflict with the existingCRZ ALT, (other than manually entering an altitude constraint),the FMC CRZ ALT will automatically be changed to the highestconstraint in the MOD plan. The resulting MOD plan will beexecutable, with a new alerting level message, CRZ ALTCHANGED TO XXXXX, displayed. Previously, the modifiedflight plan could not be executed until the flight crew manuallyresolved the altitude conflict.

New Outputs for CDS VSD and HUD (737600, 700, 800) several new parameters have been added to the EFIS outputbuses for usage by the Common Display System (CDS) Verti-cal Situation Display (VSD), HeadUp Display (HUD) System,and the Enhanced Ground Prox im i t y Warn ing Sys tem(EGPWS). The new parameters are primarily related to Ap-proach, Missed Approach, and Runway information.

Revision 3 xxv TDM 2024

Clock Source Switching Improvements clock selection whenthe GPS with Integrity option is set to OFF and the Captainsor First Officer s clock is being used is modified. Automaticswitching between the Captains and First Officer s clocks oncethe source is selected at FMC powerup is prevented. Whenthe selected source fails after powerup, the FMC will retainthe last valid clock value received from the selected source,and increment system time based on this value using its owninternal clock.

Navigation Improvements Adds GPS reasonableness checksin addition to using GPS fault indications to further protect thenavigation solution from unreasonable input data. In addition,IRS reasonableness checks have been improved in dual FMCinstallations such that both FMCs are better able to identifyand reject a badly drifting IRS.

Add FLAP/SPD Entry on APPROACH REF Page A newFLAP/SPD field has been added to the APPROACH REF pageat location 4R. Selection of a VREF speed in fields 1R3R willresult in the selection appearing in the 4R field. Location ofapproach frequency and identifier along with front course infor-mation is now located in the 4L field, and the GA N1 field hasbeen removed.

Use of Small Font on RTE HOLD Page for Default Entries Default entries for QUAD/RADIAL, INBD CRS/DIR, and LEGTIME are now displayed in small font. Large font is used todenote when the entry is either pilot entered or extracted fromthe navigation database.

Added RW/APP TUNE DISAGREE and RW/APP CRS ERRORmessages for conditions where a tuned frequency or MCP se-lected course does not match the FMC flight plan data.

Output Vref Data on the General Output Bus Vref data isnow being displayed.

Various problems detected and reported in U10.3 were cor-rected in U10.4 including the intermittent blanking of the mapon the EFIS display

The following changes/additions to software options have beenmade: Automatic EngineOut SID Selection When the Engine

Out Standard Instrument Departure (SID) software option isenabled, the FMC will look for an engineout indication fromthe Autothrottle. When the FMC receives this indicationwhile the aircraft is in climb and flaps are still extended, theFMC will automatically create a mod flight plan containingthe engineout SID for the departure runway. The automat-ic selection is only available on the 737600/700/800 air-

Revision 3 xxvi TDM 2024

craft with certain Autothrottles installed. All others mustmanually select the EngineOut SID from the DEPAR-TURES page on the CDU.

Display Missed Approach on Map in Cyan When this soft-ware option is enabled, the missed approach path is dis-played in cyan rather than magenta on the map display priorto being active.

Inhibit Gross Weight entry on PERF INIT page When thissoftware option is enabled, the entry or deletion of GrossWeight (GW) in field 1L of the PERF INIT page is inhibitedand the operator must enter Zero Fuel Weight (ZFW).When the option is disabled, there is no change from pres-ent operation in that the operator has the choice of enteringeither GW or ZFW.

Disable Takeoff Derates When this software option is en-abled, Takeoff Derate selections on the N1 LIMIT page areblanked and disabled.

The UPDATE 2 LCD MCDU (refered to as the ALT NAV MCDU)ands two functional capabilities beond performing as a normalMCDU. Provides an alternate navigation solution (requires the onside

GPS to be operational) regardless of the status of the FMC(s).The Alternate Navigation Function added to this guide requiresan ALT NAV LCD MCDU and the ALT NAV function enabled.The ALT NAV function requires an ARINC 755 MMR to supplyinputs to the ALT NAV MCDU.

Provides capability to upload and display Graphical WeatherData Maps. This function requires an ACARS/Weathermapsystem be installed and the graphics capability to be enabled.

The Update 2 LCD CDU requires its own Software Optionsdisk to enable these capabilities.

PART 11

INTRODUCTION

WHY AN FMS?

The Flight Management System (FMS) combines previous aircraftavionics capabilities with digital computers to ease your workloadand allow you to devote more time to safely managing the aircraft.The FMS provides information for continuous automatic navigation,guidance, and performance management.

Previously, you had to refer to maps, performance documents,charts, tables, or calculators for navigation and performance infor-mation. Much of this information is now stored in the Flight Man-agement Computer (FMC) and is accessible to you by the pressingof a key (or keys) on the Control/Display Unit (CDU).The FMC and the CDU make up the Flight Management ComputerSystem (FMCS). The FMC stores, in its memory, data equivalentto Jeppesen air navigation charts (called the navigation data baseor NDB) and an airplane performance manual (called the perform-ance data base). You will use the CDU to communicate with thecomputer (using ATC language) to call up or retrieve navigation andperformance data quickly and easily.

Not only does the FMCS provide fast and efficient data retrievaland calculations, but it can manage full-time flight-path (lateral, ver-tical, and speed) tracking, relieving you of menial tasks such asminor speed and heading adjustments that would otherwise con-sume a significant portion of your time.

WHAT CAN AN FMCS DO?

When you tell the FMCS where it is (origin), where it is going (des-tination), and by what route, the FMCS computes accurate presentposition and guides the aircraft from origin to destination. Whenyou tell the FMCS the aircrafts initial weight and performance re-quirements, the FMCS computes the most economical speed andaltitude to use in getting from the origin to the destination. Thrustlimit values are continuously computed during the flight.

HOW DOES THE FMCS DO THIS?

As previously stated, you communicate with the FMCS through theCDU using ATC language.

The FMCS navigates by computing accurate present position andvelocity from GP/IRS, VOR/DME, and LOC inputs.

Revision 1 12 TDM 2024

The FMCS guides the aircraft laterally and vertically by providingsteering commands to the autopilot flight director system (AFDS).The FMCS maintains economical speeds and altitudes by providingspeed commands and thrust targets and limits to the autopilot andautothrottle (A/T).The FMCS provides you with a complete range of airplane naviga-tion, guidance, flight planning, and performance data. This informa-tion is presented to you on the CDU, the Horizontal Situation Indi-cator (HSI), and the speed and thrust limit cursors on the MachAirspeed Indicator (MASI) and N1 indicators, respectively.The EFIS and CDS options replace the HSIs and ADIs with multico-lor displays of EHSI and EADI information and a MAP and a PLANmode driven by the FMC showing a graphical presentation of theflight plan path, waypoints, and additional map data from the NDB.

A MultiPurpose Control/Display Unit (MCDU) and Future Air Navi-gation MultiPurpose Control Display Unit (FANS MCDU) variationof the standard CDU are also available. The MCDUs are capableof acting as the Control/Display Unit for any ARINC 739-compatiblesystem as well as operating as a control display unit for the FMCS.

The addition of color enhances operation of the FMCS by providingthe aircrew with color annunciations of key information displayed onspecified pages.The FMCS also provides the aircrew with commonality between thedifferent 737 aircraft platforms.


PART 2

NORMAL OPERATION

SYSTEM PROMPTS QUICK REFERENCEThis section provides quick reference material for use by one famil-iar with the FMCS. For detailed information, refer to Detailed Oper-ation, which begins on page 281. Refer to the figure on page294 for CDU key locations.INITIALIZATIONWhen on the ground, the FMCS provides a logical progression ofdisplay pages for initializing the system. It does this by placing aprompt for the next logical page required at the bottom right posi-tion of the display (Line Select Key (LSK) 6R). Pressing the LSKnext to the prompt will display the next required page for initializa-tion entries. When initialization is complete, pressing LSK 6R adja-cent to the TAKEOFF prompt will display the TAKEOFF REF pagewith the PREFLT STATUS line changing to PRE-FLT COMPLETE.The POS INIT prompt is displayed on the ground as a reminderthat an IRS realignment is usually beneficial prior to every flight.SCRATCH PAD DATA MOVEMENTSCrew data entries are keyboard alphanumerics which are enteredinto the display scratch pad (bottom line) using the keyboard andthen line-selected to the appropriate data field using the appropriateLSK. Duplicating or moving existing data is accomplished by press-ing the LSK adjacent to the data, which moves it to the scratchpad. Pressing the LSK adjacent to the desired location moves thedata to that line. Entries in the scratch pad carry over to otherpages when a new page is selected.BOX PROMPTSWhenever box prompts ( ) appear on a display page, a dataentry is required for that item.DASH PROMPTSFields where data entries are allowed but are not essential forFMCS predictions, are indicated by dashes ( ) or, in somecases, a default value which can be overwritten. Dash promptentries enable the FMC to provide the most accurate computationand predictions.INVALID ENTRYIf an entry is attempted into a field which does not allow that entryor if the entry is of the wrong format or out of range, an INVALIDENTRY message is displayed in the scratch pad.


SLASH KEY and SLASH RULEThe slash key (/) is used to separate data entered as pairs in thesame field, such as airspeed and mach number (280/.720), windd i r e c t i o n a n d s p e e d ( 1 0 4 / 1 0 0 ) , o r a i r s p e e d a n d a l t i t u d e(250/10000), among others. Airspeed or mach number can be en-tered individually without using the slash key.A single leading entry of other pairs may be followed by the slashif it alone is entered or re-entered, while the trailing entry of the pairmay be preceded by the slash. If no slash is used with a singleentry, it will be inserted into the field nearest the line select key;i.e., the first entry for a pair on the left side of the CDU and thesecond entry for a pair on the right side of the CDU.If a color control display unit is installed, refer to the paragraphs oncolor displays on page 23.DATA ACTIVATION (EXEC KEY)The EXEC key is used to accept entries made to the flight plan,guidance mode, or the navigation data base. When data entrieshave been activated (by pressing the lighted EXEC key), the pagestatus title ACT appears in front of the page title.If the active data is being modified, the page status title MOD ap-pears in front of the page title. MOD is displayed in reverse videohighlighting. Until MOD is made active, the FMCS still uses theprevious ACT data, even though it is not displayed. The MODstate will be accompanied by the EXEC key being lighted unlessthe MOD has created an impossible situation; e.g., an altitude con-straint in the flight plan higher than cruise altitude.If a color control display unit is installed, refer to the paragraphs oncolor displays on page 23.ERASEWhenever a MOD is made to active data, an ERASE prompt willappear. Pressing the ERASE LSK erases the modification andreturns the display to the active page.NEXT PAGE / PREV PAGE keysWhen a display consists of multiple pages, the additional pagesmay be displayed by using the NEXT PAGE or PREV PAGE keys.Multiple page displays wrap around from first page to the last pageand vice versa (for example from page 5/5 to page1/5).ALTITUDE/FLIGHT LEVELSAltitude or flight level is accepted by the system in various forms.An altitude entered with three digits or less is interpreted to be a


flight level; for example, 300 will be interpreted and displayed asFL300. Entries of low altitudes (less than 1000 feet) may be madewith leading zeros to avoid confusion with flight levels; for example,0300 for 300 feet or 0030 for 30 feet. Generally, if the entry is ator above the transition altitude, it will be displayed as a flight level;otherwise, it will be displayed in feet. Three exceptions to this ruleare:

TRANS ALT always displayed in feet. TRANS LVL always displayed as a flight level. ELEV always displayed in feet.

COLOR DISPLAYSWhen the FMC is connected to a color control display unit and theColor Software Option is enabled, certain functions and data areannunciated using color in the displays. In the remainder of thisguide, color is indicated in bold text on pages identified as Update10.2A (U10.2A).Displays are colorized according the following guidelines.

The following are displayed in large font shadedwhite text. ABEAM PTS prompt when selected (until executed or can-

celled). ACARS prompts (other than ACCEPT/REJECT)when se-

lected and until message is delivered to the ACARS MU orFMC is unable to deliver the down link to the ACARS MU (3seconds minimum).

EXIT ARMED prompt after EXIT HOLD prompt is executed. LT ENG OUT or RT ENG OUT prompt on the ENG OUT

CLB page when selected (these prompts work as a toggle). MOD when it appears in the page title. Modification entries manually entered or from ACARS

uplinks (including entries which are propagated onto pagesother than the page entered on) until executed or cancelled.

Navigation position selected on the POS SHIFT page (untilexecuted or cancelled).

Prior to activation, RTE, RTE LEGS, RTE DATA, and HOLDpage titles are displayed in large font cyan.

The following are displayed in large font magenta when theroute is active: Active FMC waypoint on RTE, RTE LEGS, RTE DATA, and

HOLD pages.


Active FMC target altitude (RTE LEGS page) (font sizerules apply).

AT when displayed speed/altitude or altitude is the currentFMC target speed/altitude or altitude unless the displayedE/D ALT or speed/altitude is the result of a subsequent re-striction on CLB and DES pages.

BEST SPEED when displayed speed is current FMC targetspeed.

CRZ ALT when displayed value is the current FMC targetvalue.

E/D ALT when displayed altitude is active FMC target alti-tude.

QUAD/RADIAL when the aircraft is active in the hold (fontsize rules apply).

INBD CRS/DIR when the aircraft is active in the hold (fontsize rules apply).

LEG TIME when the aircraft is active in the hold (font sizerules apply).

LEG DIST when the aircraft is active in the hold. RTA SPEED when displayed speed is current FMC target

speed or or active speed restriction. RTA time when displayed (RTA Mode active). RTA WPT when it is the active waypoint. SPD REST when displayed speed is the current FMC target

speed.NOTE: When CAS and MACH are displayed together, only

the active measurement standard is displayed inmagenta, i.e., in normal descent, the MACH value isdisplayed in magenta until the CAS/MACH transitionpoint is reached, then the CAS value is displayed inmagenta.

Revision 3 24.1 TDM 2024

TGT SPD when displayed speed is the current FMC targetspeed.NOTE: When CAS and MACH are displayed together, only

the active measurement standard is displayed inmagenta, i.e., in normal descent, the MACH value isdisplayed in magenta until the CAS/MACH transitionpoint is reached, then the CAS value is displayed inmagenta.

The following are displayed in large font green text. Actively tuned VOR, ILS, or DME data (frequency, station

ID, and course) on NAV STATUS page, when the navaid isused in the navigation solution.

Active state (ON/OFF) of alternate navaids on the NAV OP-TIONS page.

LANDING REF (QNH/QFE) toggle selected mode. RW COND (DRY/WET SKR) toggle selected mode(s). TAKEOFF REF (QNH/QFE) toggle selected mode.

Map pages are displayed in full color.

All other data and headers not affected by specific colorizationare displayed in white text.

MESSAGESThe system displays messages in the scratch pad which areworded to allow easy identification and corrective action if required.When a message is received, the MSG annunciator on the CDUlights. High priority messages also cause the FMC annunciator onthe FMA to light. Any data displayed in the scratch pad has priorityover messages. Messages are prioritized, with the highest prioritymessage displayed first.NOTE: DELETE is treated as a message.

Messages may be cleared by pressing the CLR key. Some mes-sages will be cleared automatically when no longer appropriate.

Alerting and advisory messages are covered in detail in Non-Nor-mal Operation, Part 3.


TYPICAL FLIGHT QUICK REFERENCEThe following section contains a quick-reference checklist arrangedby phase of flight over a U.S. route. A route from Chicago (KORD)to St. Louis (KSTL) is shown for all FMC displays. This section isintended to provide you with the basic information needed to useeach of the CDU pages. The navigation and performance datashown on the following pages are intended only to provide a gener-al description of system operation. These displays are typical, butnot necessarily representative of any specific airline operator. Eachpage is tabbed to provide quick access to the needed information.If you find that not enough information is provided on these pages,turn to the corresponding page(s) in the DETAILED OPERATIONsection, which are referenced at the bottom of each page if applica-ble.
