Designed to be a powerful naviga-tion tool, the Bendix GC 360ARadar Graphics Unit generates amoving-map display on your weath-er radar indicator, showing yourposition with respect to the flight-planned course and waypoints,nearby airports and navaids, and, ofcourse, weather. It continuouslyupdates the graphic picture of youraircraft’s position over the ground,making it easy to visualize the pre-cise navigation situation.

During flight the GC 360A allowsyou create new waypoints directlyon the radar screen, incorporatingthem into the flight plan with theLNAV. Course deviations due toweather or ATC requests canbecome easier to fly with positivecourse guidance provided by theGC 360A’s joystick-controlled, way-point feature.

The radar graphics unit is compati-ble with dual LNAV or with a singleLNAV as Nav 1 and a King GoldCrown KNR 634A Nav/KDM 706Aor DM 441B DME combination asNav 2. It can generate radar dis-plays for a variety of informationcomputed by the LNAV, includinglocations of waypoints in the flightplan, course lines, nearby airportsand navaids, and real-time winddata. Interfaced with a KNR 634ANav/KDM 706A or DM 441B DMEcombination, the GC 360A can dis-play secondary navaid position andradial guidance graphics in the Nav2 and BOTH modes.

By presenting navigation informa-

tion in a simple and clear format,the GC 360A can help you deter-mine solutions to navigation prob-lems you otherwise might not see,providing a valuable complement toany Bendix RDS 81, 82, 84, 86,ART 2000 or 2100 weatherradar/King KNS 660, KLN 88, KLN90, KLN 90B, KLN 900 or GNS XLSinstallation.

The GC 360A also provides check-list features that enable you to runnormal and emergency checklistson your weather radar indicator.The graphics unit’s nonvolatilememory contains room for 935 linesof information, generally enough forany aircraft’s entire checklist libraryplus tables of information such asemergency or best-performanceairspeeds and aircraft weight-and-balance. During checklist operationits color coding systems helps youkeep track of checked andunchecked items, providing statusmarkers for when you need to leavethe checklist to operate the GC360A temporarily in any othermode.

This GC 360A Pilot’s Guide isdesigned to acquaint you with theradar graphics unit’s functions andcontrols and to show ways to use itas a navigation tool. After reviewingthis Guide and practicing radargraphics operations in your aircraftfor a little while, you should begin tohave an understanding of how touse the GC 360A to its best advan-tage, giving you the maximumreturn on your investment inAlliedSignal avionics.

Bendix RDS 81, 82, 84, 86,ART 2000 or 2100Weather Radar Indicator

SYSTEM COMPATIBILITY

This GC 360A Pilot’s Guideassumes that the operator isalready proficient in basic operationof the Long Range NavigationSystem and weather radar. If not,refer to their respective Pilot’sGuides for operating instructions.

The navigation information present-ed by the GC 360A is not to beused for primary navigation.Contents of the checklists are theresponsibility of the user/installer.

(1) MODE SELECTOR

Activates any of the GC 360A’s sixmodes of operation. With the modeselector in the OFF position, theradar graphics unit is inoperative.The radar is capable of displayingweather/ground surveillance infor-mation only.

Selecting either √LST or EMER pre-pares the GC 360A to run aircraftchecklists programmed with the KA68 or KA 68A Pocket Terminal (seeProgramming, page 21). When youselect a checklist mode, with theweather radar operating in Standby,the GC 360A displays the appropri-ate Index page and assigns check-list functions to the five pushbuttoncontrols on the left half of the face-plate.

While programming checklist infor-mation with the Pocket Terminal,use the mode selector to storechecklists in either the normal oremergency checklist memory.

Select the Standby mode to eraseall Nav graphics temporarily fromthe screen whenever you want anunobstructed view of the weatherahead. You may also selectStandby prior to aircraft shutdownand remove power from the GC360A with the avionics masterswitch.

Activate any of the three navigationmodes to display navigation graph-ics on the radar screen. Thesemodes also assign navigation func-tions to all controls on the radargraphics unit’s faceplate. The GC360A must be interfaced to either aLNAV or a KNR 634A navigationreceiver and a KDM 706A/DM 441BDME as Nav 2 to generate graphicsin the Nav 2 or BOTH modes.

MODES AND FUNCTIONS

(3) CURSOR CHECK-OFF KEY

In any navigation mode, the check-off key has two primary functions.During normal course plotting, italternately removes and replacesthe course line on the radar screen.The waypoints, though, remain inview continuously. When establish-ing a temporary waypoint with thejoystick, pressing the check-off key“freezes” its lat/lon coordinates,transferring them to the LNAV’swaypoint data page, allowing you toinsert it in your flight plan.

With the GC 360A in a checklistmode, pressing the check-off keyactivates the line item highlightedby the cursor. If an index page isdisplayed, operating the check-offkey will call to the screen the high-lighted checklist. If a checklist pageis on the screen, the key will checkoff the highlighted item, changing itscolor code to green, and repositionthe cursor on the next uncheckedline item.

(4) CURSOR POSITION /REFERENCE KEYS

Reposition the cursor up or down,without altering line item colorcodes, in checklist modes. Youmay select checklists to run or passover line items without checkingthem off.

It’s helpful to think of the cursor as a“circular” function, with one off-screen position. In some cases youcan reference a line item morequickly by moving the cursor uppast the top of a checklist to theopposite end.

Upon reaching the bottom of a list,pressing the cursor down keyremoves the yellow highlight fromthe radar screen. Pressing it againcauses the cursor to reappear, atthe top of the first page of thechecklist in use. You may alsoremove the cursor from the radarscreen from the top of a checklistand have it reappear at the bottomby using the cursor up key.

The reference function is availablein any navigation mode, andenables the radar graphics unit todisplay nearby DME-equippednavaids (Vortacs, VOR/DME’s,Tacans) whose position is currentlybeing monitored by the LNAV. Itcan distinguish between high-alti-tude, low-altitude and terminalnavaids.

(5) INDEX/NAME KEY

Displays the appropriate indexpage on the radar indicator in eitherchecklist mode, with the cursorhighlighting the checklist currentlyin use. Pressing the IDX key alsorestores the checklist in use to itsoriginal, unchecked form.

The name function is available inthe navigation modes. It alternatelyremoves and displays the names ofall waypoints on the radar screen.Waypoint numbers, though, appearcontinuously with a KNS 660, KLN88 or KLN 90 interface. Waypointnumbers will not be displayed with aKLN 90B, KLN 900 or GNS-XLSinterface.

5

(6) PAGE KEY

Permits fast review of checklist andindex pages. Press the Page key todisplay pages in consecutive order,returning to the first immediatelyafter displaying the last. KeyingPage does not move the cursorposition.

(7) WIND KEY

While using the LNAV in flight, youmay view current wind speed anddirection with the GC 360A operat-ing in the 360˚ circle mode. Thewind function displays total windvelocity, direction and headwind /tailwind component.

(8) 360˚ KEY

Shifts the navigation map displayinto and out of the circle mode. Afull compass rose appears on theradar screen with a white delta attop indicating present heading.Navigation graphics may appear atany point within the compass circle,but weather information is restrictedto its normal 120˚ (or 90˚) sectordisplay. A large color coded dot -cyan for Nav 1, yellow for Nav 2 -will appear on the compass circle tomark the current bearing to theactive waypoint.

(9) CANCEL PUSHBUTTON

Removes the Disclaimer messagefrom the radar screen. In navigationmodes, pressing the Cancel push-button erases graphics related tojoystick operation.

(10) JOYSTICK CONTROL

Creates a temporary waypoint thatcan be used to route around haz-ardous weather or to comply withATC requests. Moving the joystickfor a moment, and then releasing it,displays the GC 360A’s Waypointcursor at the center of the radarscreen, along with the correspond-ing lat/lon position in the lower rightcorner and a “cursor” annunciator toits left. By moving the joystick in theappropriate direction, and holding itin place, you may relocate the tem-porary waypoint to any position onthe radar screen, whether the nor-mal sector display or 360˚ circlemode is active.

The joystick control has no check-list-related function.

6

To begin radar graphics operation,rotate the GC 360A’s mode selectorclockwise to the desired positionafter turning on the aircraft’s masterand avionics master switches. Withthe mode selector set to any posi-tion other than Off or Standby, andthe radar operating in a weathermode or in Standby, the followingdisclaimer message will appear onthe radar screen:

The disclaimer will extinguish byitself after approximately 20 sec-onds of display. Also, it may beremoved at any time by pressing thGC 360A’s Cancel pushbutton.

You may also interrupt the dis-claimer message before its displaytime has elapsed by turning themode selector to Standby. In thatcase, repositioning the selector toany other position but Off will recallthe disclaimer to the screen for thebalance of its 20 second displayperiod, after which it will extinguishautomatically. Again, press theCancel button at any time to clearthe disclaimer from the radarscreen.

During aircraft shutdown periods,you may leave the mode selectorset to Standby and remove powerwith your aircraft’s avionics masterswitch. As with all avionics, it isgood practice to make sure that nopower is reaching the GC 360A dur-ing engine startup or shutdown.

Certain radar graphics modes -EMER, √LST and BOTH, as well asthe GC 360A’s 1000 nm range nav-igation map - require that the radarbe set to Standby. If the radar isoperating in a weather mode withthe GC 360A’s mode selector set toany of these modes, a “SELECTSBY” annunciator will appear on theradar indicator next to the Standbyselector. No weather information isavailable when the radar is operat-ing in Standby.

As a reminder that the weatherradar must be operating in the nav-igation map mode to display navgraphics from the GC 360A, a white“Push Nav” annunciator appears asnecessary, adjacent to the radar’sNav Map key.

BASIC OPERATION

GENERAL INFORMATION

During all navigation operationsusing single or dual KNS 660, KLN88, KLN 90, KLN 90B, KLN 900 orGNS XLS Long Range NavigationSystems and your RDS 81, 82, 84,86, ART 2000 or 2100 weatherradar, the GC 360A generates radardisplays that help you visualize youraircraft’s position with regard toimportant aspects of the flight.These include: the flight plannedcourse; weather detected by theradar; navaids and pilot program-mable waypoints; and nearby air-port locations.

The GC 360A is also compatiblewith the KNR 634A Nav receiverand the KDM 706A or DM 441BDME only in the Nav 2 mode,though, and only with an LNAV asNav 1. Area navigation functionsare not available from the KNR634A / DME combination, however,so radar graphics are limited toactive navaids and radial coursedisplays. The radar graphics unitreceives aircraft heading informa-tion from the LNAV which must beoperating for the GC 360A to createNav 2 graphics.

The joystick-controlled waypointfunction of the GC 360A alsorequires the LNAV in order to oper-ate; therefore it cannot be refer-enced to the KNR 634A / DME com-bination. Referenced informationabout nearby airports or navaidsthat are not part of the flight plan, orcurrent winds, are also availableonly in modes coupled to the LNAV.

The GC 360A generates navigationdata blocks that display the alphaidentifier of the active waypoint(from the LNAV) or the frequency ofthe navaid in use (from the KNR634A/DME), as well as heading,course and distance information. Aseries of dashes replaces any navi-gation information unavailable tothe GC 360A.

Throughout all navigation opera-tions, Nav 1 data references appearon the radar indicator in cyan (lightblue), with Nav 2 information in yel-low. Aircraft headings and activewaypoints appear in white, as docourse lines, which the GC 360Adisplays to any active waypoint thatis not farther than 1024 nm away.Range scale numbers are dis-played in green.

Whenever the active waypoint can-not be displayed on the radar indi-cator due to distance or relativebearing with the GC 360A operatingin its sector mode, an off-screenwaypoint indicator will appear as anarrow at the bottom of the indicator,next to the waypoint’s identifier.Eight pointer positions, spaced 45˚apart, are possible, so the arrow’ssensitivity should be considered as+/-22.5˚. The off-screen waypointindicator does not appear when theGC 360A is operating in its 360˚ cir-cle mode; instead, refer to the color-coded RMI dot for waypoint bearinginformation.

The radar graphics unit employsthree different symbols to indicatethe nature of navigation references.

8

NAVIGATION GRAPHICS

If the waypoint is a navaid, a Vortacsymbol ( ) appears. If it is a pilot-programmed point in space, a four-pointed star ( ) is used. A cross ( )symbol indicates that the waypointis an airport.

At any time the mode selector is setto a position that requires informa-tion from a navigation sensor that isturned off, or when the GC 360A’smode selector is set to Standby andthe radar is operating in its Nav Mapmode, a yellow “No Nav” annuncia-tor will appear in the position on theradar indicator normally occupiedby that sensor’s data block. Forexample, if no navigation sensor iscoupled to the GC 360A’s Nav 2

channel, “No Nav” appears in theappropriate positions on the indica-tor with the radar graphics units setto the Nav 2 or BOTH modes.

Throughout radar graphics opera-tions, it is the pilot’s responsibility toensure that navigation graphics donot interfere with interpretation ofweather depicted by the radar.

You can declutter the screen selec-tively by deactivating pilot-selec-table display functions such asReference, Wind or course linegraphics; or all at once by settingthe GC 360A’s mode selector toStandby.

Off-screen WaypointIndicator

With the radar operating in a weath-er mode and the GC 360A set toNav 1, navigation graphics appearin the format shown above.

Graphics related to Nav 2 inputs areidentical to Nav 1 formats, but the

information appears in yellow ratherthan cyan. Also, the white Nav 2course line is dashed rather thansolid. Selecting the radar’s Standbymode clears the indicator of allweather related information, includ-ing the antenna tilt annunciator.

Select the BOTH mode to view nav-igation graphics from Nav 1 andNav 2 sensors simultaneously.Since this NAV mode requires theweather radar to be n standbymode, weather information will notbe displayed along with the naviga-tion graphics. Data blocks contain-ing waypoint name, bearing anddistance information appear in thesame format as during single navoperations. The current HSI coursenow appears above the appropriatenavigation sensor’s data block.Information about the active Nav 1waypoint appears on the left side ofthe screen, in cyan, with Nav 2 dataon the right, in yellow.

90˚ SCAN RADARS

When installed with the 90˚ scanRDS 81, 82 or ART 2000 weatherradar, the navigation data blocksgenerated by the GC 360A appearin the same format in both 90˚ sec-tor and 360˚ circle modes. In singlenav modes, the flight-plannedcourse and waypoint name, bearingand distance information appear inthe lower right corner of the radarindicator. With the GC 360A set toBOTH, navigation data from the twosensors appear in the indicator’slower opposite corners.

In any of the three navigationmodes, the GC 360A offers a vari-ety of pilot-selectable functionsdesigned to assist in navigationdecision-making and altering pro-grammed flight plans while enroute. Basic control information isincluded in “Modes and Functions”on page 4. Following are amplifieddescriptions of the GC 360A’s morepowerful functions.

1. Cursor Check-Off

Removes and replaces Nav 1 andNav 2 course lines on the radarscreen. Also summons the LNAV’swaypoint page and sends it lat/loninformation when the joystick-con-trolled waypoint Joystick Waypointis on the radar screen.

2. Reference

Collocated with the cursor positionkeys, the Reference keys com-mand the GC 360A to display onthe radar indicator up to 10 Vortacs,VOR/DMEs and Tacans near theaircraft’s position.

As with cursor position control dur-ing checklist operations, theReference key is “circular”.Pressing the Reference “up” keyonce causes the GC 360A to dis-play nearby high-altitude, low-alti-tude and terminal navaid refer-ences on the indicator. Pressing the

Reference “up” key a second timeremoves terminal navaids from theindicator; a third press removeslow-altitude navaids, while pressingthe Reference “up” key a fourth timeclears the indicator of all referencenavaids.

The Reference “down” key oper-ates in the same manner, but stepsthrough the navaid sequence in theopposite order.

The Reference function generatesa small green annunciator, in theform of the letter “R,” with one, twoor three dashes stacked vertically toits immediate left to show whetherhigh altitude, high and low-altitude,or high-altitude, low-altitude and ter-minal navaids are on the screen.

3. 360˚ Circle Display

The 360˚ key shifts the radar dis-play from a sector scan to a full cir-cle, and back again, allowing you toview navigation data in all quad-rants. Weather information remainslimited to its normal 90˚ or 120˚scan. A large, color-coded dot -cyan for Nav 1, yellow for Nav 2 -will appear on the compass circle tomark the current RMI bearing to theactive waypoint. The GC 360Amust be shifted to the 360˚ circledisplay to show wind information.

11

NAVIGATION FUNCTIONS

4. Wind

Displays wind velocity at presentposition and altitude. The Windfunction is available only with theGC 360’s 360˚ circle function acti-vated.

To view the current wind speed anddirection, press the Wind key once.A solid green square on the com-pass rose will show wind direction,and wind speed will appear in greendigits beneath a “WS” annunciatoron the right side of the radar indica-tor. Press the Wind key again toview headwind (HW) or tailwind(TW) components. Pressing thekey a third time removes windgraphics from the radar screen.

5. Joystick Waypoint

You may position the joystick way-point any place on the radar screen,including behind the aircraft’s pre-sent position if the GC 360A is dis-playing its 360˚ circle format, anytime you want to alter the flight planwith reference to information on theradar screen. Moving the joystickcontrol for a moment causes thewaypoint cursor to appear; holdingit in any of its eight positions,spaced 45˚ apart, moves the cursorin that direction. Waypoint lat/loncoordinates, displayed in white nextto the “Cursor” annunciator at thebottom of the radar indicator, willchange accordingly.

During operations in the BOTHmode with dual LNAV installations,you may reference the Waypointcursor to either Long RangeNavigation System by pressing theGC 360A’s Name/Index key.Waypoint cursor coordinates will

appear on the radar screen in thecorresponding data block-left forNav 1 and right for Nav 2.

With the Waypoint cursor in thedesired position, pressing the cur-sor check-off key transfers its coor-dinates to the LNAV. A waypointpage will appear automatically onthe LNAV Display, with the identifier“O” in the case of the KNS 660,KLN 88, KLN 90, KLN 90B or KLN900. The GNS-XLS identifies thefirst waypoint received from the GC360A as “EX#01”, the second as“EX#02”, etc. The LNAV does notautomatically insert the joystickwaypoint into the flight plan;instead, you must use the normalwaypoint insertion procedures forthe particular LNAV being used.

Of course, if you want to proceeddirect to the joystick waypoint, youmay do so by using the LNAV’sDirect-To function. The GNS-XLSautomatically switches to Direct-Tomode upon receiving the joystickcursor coordinates from theGC 360A.

You may erase the Waypoint cursorat any time before its coordinateshave been transferred to the LNAVby pressing the GC 360A’s Cancelpushbutton.

12

6. Course Deviation Bar

While navigating with the LNAV, theGC 360A generates a color-codedcourse deviation bar beneath theappropriate navigation data block.With a KNS 660, KLN 88 or KLN 90interface, each mark right or left ofcenter equals 1NM for enroutemode and 0.25NM for approachmode. With a KLN 90B, KLN 900 orGNS-XLS interface, each markright or left of center equals 1NM forenroute mode, 0.2NM for terminalmode, and 0.06NM for approachmode. When the deviation bar isflagged, it extends the full distanceboth left and right of center-to indi-cate its inoperative status.

7. Nearest Airports

Although not strictly a function ofthe radar graphics unit, the GC360A allows you to display the loca-tions of the nearest airports in theLNAV’s data base. The airport sym-bols and alpha identifiers appearautomatically on the radar indicatorwhenever you select the LNAV’sNearest Airports function.

8. Map Track

The radar trackline function can beused to measure angular coursedeviations, when operating in a nonstandby radar mode. This mayassist positioning the JoystickWaypoint cursor on the indicator.The trackline will rotate left or rightby pressing the appropriate key.The trackline will extinguish auto-matically after approximately fifteen(15) minutes.

On an IFR flight from Pal-Waukee Airport,near Chicago, to Dallas-Love Field, youhave received the following clearancefrom Air Traffic Control: “Cleared toDallas-Love Field. After takeoff expectvectors out of the local area, then directBradford, via J105 to Razorback, thendirect Blue Ridge.” You have pro-grammed your LNAV with the followingflight plan:

1: KPWK (Pal-Waukee Airport)

2 BDF (Bradford Vortac)

3: SGF (Springfield Vortac)

4: RZC (Razorback Vortac)

5: BUJ (Blue Ridge Vortac)

6: HOLTS (arrival fix)

7: WEDER (arrival fix)

8: KDAL (Dallas-Love Field)

After takeoff from Pal-Waukees’sRunway 16, you receive a vectorheading of 265˚ to maintain separationfrom traffic bound for Chicago O’Hareto the south. Several minutes lateryou are cleared direct to BDF. Youraircraft is now at Position 1 on thechart illustration. The deviation barextends full-scale to the left to showthe aircraft is at least five miles right ofcourse, while the large cyan dot on thecompass rose display shows the cur-rent bearing to BDF.

Select the LNAV’s Direct-To functionand proceed to BDF. A new courseline appears on the radar indicator,direct to the Vortac from the aircraft’spresent position.

GENERAL INFORMATION

In addition to its primary role as anavigation data interface betweenyour Long Range NavigationSystem and weather radar, the GC 360A can maintain a library ofyour aircraft’s normal and emer-gency checklists. A few simple con-trol functions enable you to stepthrough checklist information, lineby line or several lines at a time,while checking off line items or leav-ing them for review at a later time.The procedures are exactly thesame whether operating in normalor emergency checklist modes.

The GC 360A’s independent mem-ory contains room for 935 lines ofchecklist information, which itdivides between normal and emer-gency checklist modes as neces-sary during programming. Thememory is nonvolatile: removingthe aircraft power supply, or evenremoving the GC 360A from itsbracket and couplers, will not affectit.

The GC 360A can be programmedwith checklist information at a qual-ified AlliedSignal service center, oryou may program the system your-self with the optional KA 68 or KA68A Pocket Terminal. The pocketTerminal provides you with the flex-ibility of being able to create newchecklists or modify existing infor-mation whenever necessary, suchas when adding new equipment orchanging flight procedures (see“Programming,” page 21).

Throughout checklist operation, fivecolor codes describe the status ofindividual line items.

Magenta, yellow and green colorcodes change in response to youruse of the GC 360A’s cursor check-off and cursor position keysdescribed in “Modes andFunctions,” on page 4. Line itemsthat appear in white or cyan cannotbe altered directly. Cyan-coloredmessages are always systemannunciators—the GC 360A’s mes-sages for you—and display infor-mation such as “End of List” or “Outof Memory.”

Pressing either the check-off key ora cursor position key will move thecursor highlight on the radarscreen.

Pressing the check-off key also willchange the color code of anunchecked line item to green indi-cating that it has now been checkedoff.

18

RUNNING CHECKLISTS

ACTIVATING CHECKLISTS

The checklist Index page automati-cally appears on the radar screenwhen you select either normal oremergency checklist modes. It pro-vides the name of every checklistavailable in that mode. You mayreturn to the Index page at any timeby pressing the GC 360A’s Indexkey.

When the Index page first appearson the screen the cursor highlightwill be positioned on the first check-list name on the list. If that is thechecklist you want to run, press thecursor check-off key to summon itfrom the system’s memory.Otherwise, use the cursor positionkeys to highlight the appropriatechecklist and then press the check-off key to bring it to the screen. Thechecklist will appear under its iden-tifying header line, with the cursorhighlight on the first item to bechecked. All other line items willappear in magenta to indicate theirunchecked status.

EXECUTING CHECKLISTS

Checking off the highlighted check-list item with the cursor check-offkey changes its color code to greenand repositions the cursor to thenext magenta line item insequence. You may step throughthe checklist in order by succes-sively checking off items with thekey, or you may run the checklist inany order you want by repositioningthe cursor with the position keys.

Pressing the cursor check-off keyupon reaching the end of a checklistrelocates the cursor to the firstunchecked line item on the list.Press the check-off key again if youwant to check off the item and pro-ceed to the next unchecked line.Otherwise you may use the cursorposition keys to move the cursor asingle line at a time, regardless ofcolor coding. It is not possible tohighlight either a white header lineor a cyan system annunciator withthe cursor.

After all line items in a list havebeen checked off, the index pagereappears on the screen. The cur-sor automatically highlights the nextchecklist in sequence.

For programming normal and emer-gency checklists into the GC 360A’smemory, the KA 68 or KA 68APocket Terminal combines all nec-essary functions in a controller thesize of a pocket calculator. Optionalequipment with the radar graphicsunit, the KA 68/KA 68A enables youto:

1. program new normal and emer-gency checklist information;

2. erase old, obsolete or incorrectinformation;

3. update checklists already storedin memory, for example, after

adding new equipment to the air-craft.

The KA 68/KA 68A Pocket Terminalprograms checklist information only.It cannot be used to program navi-gation or route information, or as asubstitute for the LNAV’s keyboard.

The GC 360A’s programmablememory can store up to 935 lines ofchecklist information. You mayeither follow the format in your air-craft’s pilot operating handbook orcreate your own. However, pleasenote the following disclaimer:

Contents of checklists are theresponsibility of the user/installer.

PROGRAMMING

Each line of checklist informationmay be up to 30 characters inlength, and entries up to 13 lineslong are acceptable. Checklistnames, however, are limited to oneline of 27 characters each. Youmay divide the memory capacitybetween normal and emergencymodes in any way you choose, sim-ply by positioning th GC 360A’smode selector to √LST or EMERduring programming: other than thetotal storage limit, there is no maxi-mum amount of information eitherchecklist mode can hold.

It is unlikely that you will ever needto program more checklist informa-tion than the GC 360A can hold, butyou should note that checklistnames in the Normal or EmergencyIndex each count as one full line ofsystem memory. The GC 360Adoes not differentiate between fulland partial lines, but counts each asone complete line. Header lines onchecklist pages and “End of List”annunciators do not count as linesof memory. If you do fill all 935lines, a cyan “Out of Memory”annunciator appears on the radarindicator, and the GC 360A will notaccept any more checklist informa-tion until you clear space in thememory.

The KA68 / KA68A keyboard isdivided between regular and shad-ed/blue functions. To enter thenumber or letter displayed in black,simply press the corresponding key.To enter a shaded/blue character,press the Shift key located in theupper left corner of the keyboard,and then the appropriate characterkey.

In addition, the KA 68/KA 68A offers

three Special Functions, describedbelow.

The following characters listed onthe keyboard are not available foruse.

They are: [ ] ↑ \.

Also, the following functions uniqueto the KA 68 have no assigned use:← SL4, SR4, Rpt, Clr, Cu, Cu>, LF,LHome, RHome and Nul. Selectingany of these characters or functionswill have no effect on checklist con-tent.

WRITING CHECKLISTS

At your option,rather than pressing the check-offkey after naming a new checklist,you may instead continue to enternew names before calling blankchecklist pages to the screen.

4. Program the new checklist bypressing the appropriate terminalkeys, and by activating CarriageReturn to terminate each checklistitem. If a checklist item is longerthan one line, you can make it morereadable by indenting subsequentlines three to five spaces each, byusing the Sp key. Activate CarriageReturn only after a checklist item iscomplete, as using it causes the GC360A to initiate a new line item withthe next keystroke.

If you discover you’ve left some-thing out while writing a checklist,use the GC 360A’s cursor positionkeys to insert a new line. The pro-cedure is the same as for writing anew checklist name on the Indexpage: move the cursor to the lineitem you want to appear directlybefore the new one and key in thenew checklist information. To cor-rect typographical errors or to erasechecklist information, refer toDeleting Text.

To continueprogramming new checklists, returnto the Index page and enter a newchecklist name or position the cur-sor on an already existing nameand press the check-off key to gainaccess to that checklist.

DELETING TEXT

The Delete function (Del) sharesthe same key on the KA 68/KA 68Aas the numeral five. To delete:

1. a single character -press theShift key and then the Del key, priorto activating Carriage Return. Youcannot delete a single characterwithin a checklist line after activat-ing the carriage return. The line itemmust be deleted and reentered.

2. a checklist line item -move thecursor to highlight the appropriateline item (or press CR if currentchecklist line is to be deleted), thenpress Shift and Del.

3. an entire checklist -with the cur-sor highlight on the appropriatechecklist name on the Index page,press Shift and Del.
