Welcome to Grand Rapids Technologies GRT Sport! We are pleased that you have chosen ourproduct to meet your flying needs.

Visit the Grand Rapids Technologies (GRT) website ( www.grtavionics.com ) for the latestupdates and supplemental information concerning the operation of this and other GRT products.

This manual describes the operation of a GRT Dual Screen Sport SX EFIS using the softwareversion shown in the Record of Revisions. Some differences may be observed when comparingthe information in this manual to other software versions. The Sport SX EFIS may optionally beequipped with processor upgrade, synthetic vision, vertical autopilot command capability,ARINC interface, XM weather, internal GPS or 8.4 inch screen. Single display systems are alsoavailable. In the few instances that the operation of other versions or configurations of Sport isdifferent than that described, those differences are described at the rear of the applicable

chapter. Every effort has been made to ensure that the information in this manual is accurateand complete. GRT is not responsible for unintentional errors or omissions in the manual ortheir consequences.

Information in the document is subject to change without notice. Grand Rapids Technologiesreserves the right to change or improve their products and to make changes in the content ofthis material without obligation to notify any person or organization of such changes orimprovements.

CAUTIONS

WARNING: Obstacle clearance is not assured in Synthetic Approach Mode.

WARNING: Various functions of this system may be incomplete or untested. Please exercisecaution when using the EFIS until a software update and a user manual corresponding to thesoftware version are provided.

CAUTION: If any display unit is inoperable, the display units will not be able to shareinformation. The pilot must account for this down-graded mode of operation and expect datawill transfer between displays.

CAUTION: If GPS position data is lost for more than 30 seconds, the EFIS Sport issues a NoGPS Position warning and automatically reverts to dead-reckoning using the AHRS heading,true airspeed, last known winds and time. This data is used to estimate changes in position,which are applied to the last known GPS position to give an approximate navigation solution.The accuracy of the dead-reckoning function will degrade with time depending on the accuracyof this data and changes in the winds.

GRT Sport Users Guide pg. iv Rev D

CAUTION: When the ground track indicator is hollow, indicating it is display-limited, the groundtrack indicated is necessarily inaccurate. This means the aircrafts track over the ground is notas indicated and the pilot should be aware of this inaccuracy with regard to obstacle and terrainclearance.

CAUTION: Dual Nav radios tuned to Localizer frequencies with autopilot function ARMengaged will result in the EFIS Sport selecting either NAV radio to fly the Localizer.

Chapter 1 TAKE OFF TOUR

1.1 Power Up

The GRT Sport has no On/Off switch andwill start to operate once power is supplied.

Power may be applied before or after theengine is started, although it is preferable todo the latter. This assures stable conditionsand normal system behavior during powerup. About 10 seconds is required for thedisplay unit(s) to start up and a similar timefor the AHRS and ADC to complete initialalignment.

Aircraft movement is allowed during initialalignment, although this motion willsignificantly extend the time until attitudeand/or heading data is accurate, thusmaking it preferable to remain motionlessduring the first 10 seconds after power isapplied.

After power-up, the startup screen will show

software and navigation database versionand GRT system status.

1.2 Knobs and Buttons

The GRT Sport system is designed to make

its use and operation simple. The left andright knobs and five white buttons are usedto access the many features in the EFIS.Menu option labels show functions for eachknob and button.

Buttons

There are five buttons. Pressing any buttonwill display the corresponding menu optionsfor that page. (The buttons may also be

called SoftKeys. They correspond toparticular software functions within the GRTSport.)

KnobsThe two knobs have two motions, rotary andpush. These provide particular functions ondifferent pages. (The knobs may also becalled rotary encoders.)

The rotary knobs also perform a variety of

secondary functions that are available byfirst pushing the knobto display a menu ofthe available functions. The availablefunctions will be listed above the knob.Twisting the knob allows you to select fromthe menu of functions, and pressing theknob will activate that function. If noselection is made from the menu within 4seconds (SET MENU, Primary FlightDisplay, Menu Time Out), the menu isremoved, and the knob returns to its primary

function.

When the rotary knob is altering any setting,the label of the item being altered isenlarged, and a flashing yellow box willappear around the items label being altered

For display screens that use the left rotary

knob for heading selection, pressing bothleft & right knobs simultaneouslywill setthe heading selection to the current heading.

2.2 Artificial Horizon

2.2.1 Artificial Horizon

The Artificial Horizon is just that, a pictorialrepresentation of the earth. The blue portionrepresents the sky; the brown portionrepresents the ground.

2.2.2 Synthetic Vision

Synthetic Vision is an available option on theSport SX. When selected, a 10 mile forwardout the window view of the topographyaround the current aircraft position is

presented on the PFD and a top downview is displayed on MAP pages WhenTerrain is enabled, red (0-500 ft) and yellow(500 1000 ft) warnings are overlaid on theSynthetic Vision displays.

Selecting Synthetic Vision

To select Synthetic Vision mode, press anybutton then NEXT (more than once may berequired) until the SV label appears. The

button under the label will select betweenON (turns on Synthetic Vision), Terrain(turns on Terrain Warning See Section 3.11)and OFF (turns off Synthetic Vision andTerrain Warning and restores brown andblue background).

2.2.3 Sky Pointer

Note that the aircraft wings or pitch bars

and the triangular pointer move so thepointer always points up or towards the sky.This is called a sky pointer representationand provides guidance for recovery fromunusual attitudes. This representation isopposite that of conventional generalaviation attitude indicators.

2.2.4 Pitch Ladder

A portion of the artificial horizon is the Pitch

Ladder. It depicts pitch angle of the aircraftin relation to the horizon. It is normally set(SET MENU, Primary Flight Display, PitchLadder Offset) so that straight and levelflight at normal cruise speed is 0 pitch (barsalign with the horizon).

2.2.5 Flight Path Marker

The Flight Path Marker, shown as a circlewith three spikes is a projection of the

aircrafts flight path and predicts the futureposition of the aircraft based on currentaircraft state parameters (attitude, speed,wind etc) and assumes they remainconstant. The FPM will appear to floatabout the display as the aircraft pitches androlls. This movement is most evident instrong crosswind or unusual attitudes.

2.2.6 Flight Director

Both Lateral and Vertical autopilot functionsmust be enabled in General Setup. Theflight director is controlled by the autopilotfunctions even if you don't have an autopilot.The flight director is activated in the secondstep of the altitude selection menu on thePFD (push the right knob twice). The FLTDIR button switches the flight director on

and off. When active, the wing/noseindicator is replaced with a yellow upside-down V at the center and yellow bars to theside. The computed roll and pitch are

indicated by a magenta V with raisedoutside edges. Any active needles will bereplaced with scales to make room. To flythe flight director, adjust the pitch and roll ofthe plane to fit the yellow V into themagenta V. The indicator shows the samecommand sent out to an autopilot. The flightdirector has no special indication while onthe ground or during take-off and will show alevel command if a command can't becomputed.

2.3 Airspeed Tape

The Airspeed tape displays airspeed andthree user selectable speed bugs whichappear as magenta triangles with letters X,Y, & G for Vx, Vy and Vg. The Bugs are setin the SET Menu, General Setup, PrimaryFlight Display.

The background colors of the airspeed tape

are the standard airspeed color segments.The background color is red above VNE, (themaximum demonstrated safe airspeed thatthe aircraft must not exceed under anycircumstances). It is yellow in the cautionarea, from VNO (maximum structural cruisespeed) to VNE. It is green from VS1 to VNO.VS1 is the stall speed with flaps and landinggear retracted. It is white from VSO to VFE.VSO is the stall speed with flaps and landinggear extended, and VFE is the highest speed

at which flaps can be extended. The color isuser selectable to be red or none below VS1.

Between the airspeed tape and window isthe trend indicator. This is a red arrow thatindicates the direction and rate of airspeedchange and points to the airspeed the

aircraft will be at in 5 seconds. It onlyappears if the airspeed is changing.

2.4 Altimeter Tape

The Altimeter Tape displays altitude abovemean sea level (MSL) in hundreds of feet.The background color of the altimeter tapeshows the Off Route Obstacle ClearanceAltitude (OROCA) which provides 1000 footobstruction clearance in non-mountainousterrain areas and 2,000 foot obstructionclearance in designated mountainous areaswithin the United States. An altitude below

the OROCA is shown yellow, above theOROCA is shown green.

To set the barometric pressure value onthe altimeter:Turn the right knob on any PFD page.When the desired barometric value isdisplayed in the lower right corner, press theknob to enter.

You may set an altimeter bug or preset

altitude on the altimeter tape to provide avisual alert of an important altitude. It willdisplay as two magenta triangles.

Setting an altimeter bug will also cause agreen arc (altitude intercept arc) to appearwhen a MAP page is displayed. The greenarc shows where you will be located whenthe preset altitude is reached. This featureworks both in climb or descent. The arc willmove as VSI and speed changes occur. It is

helpful as a backup to monitor progresstowards hitting crossing restrictions orarriving at pattern altitude (Chapter 3.6).

And finally, a preset altitude serves as thehold altitude for autopilots with verticalsteering capability (Chapter 5.3.2).

To set an Altitude bug:1. Press the right knob on any PFD

page.2. Turn knob to desired Altitude

3. Press knob to set.

2.5 Vertical Speed Tape

Just to the left of the altimeter tape is thevertical speed tape. It shows vertical speedin feet per minute. The vertical speed isalso presented digitally, at the bottom of thescale when descending and at the top of thescale with climbing.

2.6 Heading Tape

A portion of the Heading Tape (70 degrees)is presented at the top of the display anddisplays four parameters:

Magnetic Heading (point up triangleH underneath)

GPS Ground Track (point downtriangle with T underneath)

Bearing or Course to current GPSwaypoint (pair of invertedtriangles)

Heading Bug (pair of squares)

The center of the heading tape (positionover the center of the bank indices) is userselectable to be either Magnetic Heading orGround Track. (SET MENU, Primary FlightDisplay, Up reference). The display at thecenter above the bank indices presents thesame information in numeric format as wellas the label HDG or TRK to indicate thecurrent selection.

Current Magnetic Heading is displayed onthe Heading Tape as a point up triangle. IfMagnetic Heading is not selected as UpReference, the triangle will have an Hbelow it. Its position relative to the Ground

Track indicates the current differencebetween ground track and magneticheading.

Ground Track, derived from GPS data(requires a GPS source), is displayed on theHeading Tape as a point down triangle. IfGround Track is not selected as UpReference, the triangle will have a T belowit. Its position relative to the MagneticHeading indicates the current differencebetween ground track and magneticheading.

The Bearing (or GPS Course) to the

currently selected waypoint is displayed onthe Heading Tape as two inverted triangles.Maneuvering the aircraft so that the groundtrack indicator is aligned with this indicatorwill result in a ground track directly to thewaypoint.

The Heading Bug is displayed on theHeading Tape as two side by side squaresand also in the data box above the left knob(SEL HDG). It is used to manually control

the autopilot or as a visual reminder ofdesired heading. The heading bug is set byturning the left knob on a PFD or MAP pageto the desired heading. Or, to select thecurrent heading, press both knobssimultaneously.

Occasionally one or more of the parameterswill be off the Heading Tape, since the tapedisplay is limited in width to 70 degrees. For


22/91


example, if there is a change in course at awaypoint greater than 35 degrees, theBearing to the GPS waypoint triangles orHeading Bug squares or both may be off the

tape. Likewise if there is a strongcrosswind, the Ground Track triangle andMagnetic Heading triangle may be morethan 35 degrees different. When anyparameter is off the tape display, thatparameter is said to be display limited.When a parameter is display limited, thetriangles or squares will be outlines orhollow, not filled in or solid. Display limitedparameters do occur, but they are anexception rather than the norm. The GRT

handling of them described below makestheir occurrence a trivial matter.

When a parameter is display limited, it willbe displayed at the left or right end of thetape. The end chosen is the direction to turnthe aircraft to get the parameter onto thetape and out of display limited. Forexample, if the Magnetic Heading is 270 andthe GPS Ground Track is 220 (strong windfrom the North) the display limited Ground

Track triangle will appear on the left end ofthe tape indicating a left turn is required toget the Ground Track triangle back on thetape and out of display limited.

The relative position between two displaylimited indicators remains accurate,allowing the pilot to align them to achievethe same result as if they were not displaylimited.

When the Ground Track indicator is display-limited, the Flight Path Marker and ground-referenced symbols (runways andobstacles) are artificially shifted so that theyremain on the screen, but in such a way thattheir position relative to each other iscorrect. This allows these items to be visible

on the screen no matter how large the driftangle.

Should the Flight Path Marker becomedisplay limited, it will appear red.

If Lateral Autopilot Functions are ON (SetMenu, General Setup, Lateral AutopilotFunctions), The Bearing to Waypoint,Ground Track and Magnetic Headingtriangles and Heading Bug squares will beeither white or magenta. Magenta meansthat indicator IS coupled to the autopilot andwhite means that indicator is NOT. Forexample, when you select LAT A/P HDG(heading) the Heading Bug squares and the

Magnetic Heading triangle turn magentaand the Bearing to Waypoint triangles andGround Track triangle are white. When LATA/P ENAV is selected and a GPS is selectedas the Nav source, the Bearing to Waypointtriangles and Ground Track triangle turnmagenta and the Heading Bug squares andthe Magnetic Heading triangle are white.

If Lateral Autopilot Functions are OFF (noautopilot in use), the Magnetic Heading

triangle and Heading Bug squares will bewhite and the Ground Track triangle andBearing to Waypoint triangles will bemagenta.

CAUTION: When the Ground Trackindicator is hollow, indicating it is display-limited; the ground track indicated isnecessarily inaccurate. This means thatthe aircrafts track over the ground is notas indicated, and the pilot should beaware of this inaccuracy with regard toobstacle and terrain clearance.

2.7 Wind Speed/Direction

The wind speed and direction is available intwo formats as described and selected in thePrimary Flight Display settings page.

The vector representation of wind direction(the arrow drawn on the screen) shows winddirection relative to the aircrafts heading. Awind vector pointing directly up indicates atailwind and a vector pointing to the rightindicates the wind is blowing from left toright.

The numeric display of wind direction is

relative to magnetic north.

If insufficient data exists for calculation ofwinds, the wind vector arrow, and digitaldata, is blanked (not displayed). Calculatedwinds are based on GPS ground track andgroundspeed, and heading and airspeeddata provided by the AHRS. Accurate windsrequire accurate magnetic heading andairspeed data. Calibration procedures tocorrect for heading and airspeed errors are

provided, see Chapter 9, Calibration.

In addition to wind direction and speed,Head/Crosswind components may bedisplayed as well (SET MENU, PrimaryFlight Display, Digital Head/Cross WindDisplay).

2.8 Turn Coordinator

The Turn Coordinator is depicted at the topof the pitch ladder and below the headingwindow as inverted green triangles. TheGRT Sport calculates the angle of bankrequired to make a Standard Rate turn atthe current airspeed. The Turn Coordinatortriangles will spread out or in as the airspeedincreases or decreases.

2.9 GPS CDI Display

The GPS CDI (Course Deviation Indicator)is located at the bottom center of the screen.It displays the direction and magnitude ofthe GPS cross-track error. The cross-trackerror is the distance from the aircraftscurrent position to the line connecting theprevious and next waypoint in the GPS flightplan. (When only one waypoint is active inthe flight plan, the GRT Sport, like mostGPS navigation equipment, will use theaircrafts position at the time the waypoint isselected as the previous waypoint positionfor purposes of calculating cross-track

error).

The cross-track deviation is represented bythe deflection of the bar from the center ofthe CDI scale. A deflection to the leftindicates the airplane needs to bemaneuvered to the left to get back oncourse. The center of the CDI includes atriangle that points up or down to indicateTO or FROM the GPS waypointrespectively. Note: FROM indications result

in reverse sensing for the deviationindicator, identical to that of a VOR type CDIindicator. This allows normal sensing whentracking outbound from a GPS waypoint.

The deviation bar and TO/FROM indicatorare be displayed whenever a GOTOwaypoint is active in the GPS flight plan.

The scaling of the CDI indicator changesautomatically from 5.0 nm full scale when

enroute, to 1.0 nm full scale in terminalphase (within 30 nm of the destination), to0.3 nm during approach phase. Approachphase can be detected by the GRT onlywhen Aviation format of GPS data isprovided to the GRT Sport.


24/91


2.10 Angle of Attack

Angle-of-Attack is calculated by the EFIS bycombining a variety of sensor data. It maybe used to drive two different indicators onthe PFD screen.

Angle-of-attack is not of much value for mostphases of flight, but is useful for stallwarning, and to a limited extent, as a meansof establishing an approach speed thataccounts for the current weight of theairplane.

2.10.1 Approach AOA Indexer

This indicator appears just to the right of theairspeed tape, and shows the angle-of-attack relative to the optimal for approach.When the angle-of-attack is too low (theairplane is flying faster than optimalapproach speed), yellow chevrons pointingup into a yellow circle prompt the pilot toincrease back pressure to reduce speed.When the angle of attack is too high (theairplane is flying slower than optimal

approach speed), red chevrons pointingdown into a red circle prompt the pilot topush forward to increase speed. When stallis imminent, the word "PUSH" appearsabove the AOA indexer.

The indexer will show a green circle, with nochevrons, when the angle-of-attack is in theoptimal range.

WARNING: The use of this indication is

purely at the judgment of the pilot. Theaccuracy of this AOA indexer, and itsstall warning, is affected by EFIS sensorerrors and the accuracy of the calibrationprocedure. The EFIS calculation of angle-of-attack, and the approach AOA indexershould not be used as the only stallwarning instrument.

The approach AOA indexer will not appearat low angles-of-attack.

AOA Slightly High Need to Pitch Down

2.10.2 Barber-Pole Stall Speed Indicator

A vertical red/black bar is displayed on thebottom half of the airspeed tape. The top ofthis bar corresponds to the stall speed at thecurrent "G" loading, and is based on the stall

speed entry made in the EFIS, and thenormal acceleration "G's" sensed by theAHRS.

2.10.3 Pitch Limit Indicator

When enabled on the PFD settings page,the pitch limit indicator appears on the PFDscreen when the angle-of-attack is less than8 degrees from stall, and goes away whenthe angle of attack more than 9 degrees

from stall. The indicator moves downwardtoward the nose or bars pitch indicator asthe angle of attack increases. Stall will occurapproximately when this indicator is on thenose or bar pitch indicator. This indicator willbe limited to 30 degrees pitch to preventchasing a pitch limit that could temporarily


25/91


be at a very high pitch angle due to highairplane speed.

The pitch limit indicator was originally

created to give pilots a maximum pitch anglereference when performing a windshearescape maneuver. While this may be of littleuse for the typical experimental aircraft pilot,it could be useful for assisting with terrainavoidance in a low airspeed situation. In thatcase, the pilot can use the pitch limitindicator as an approximate reference of apitch angle that will result in stall.

WARNING: The use of this indication is

purely at the judgment of the pilot. Theaccuracy of this information is affectedby EFIS sensor errors and the accuracyof the calibration procedure. The EFIScalculation of angle-of-attack, and thepitch limit indicator should not be usedas the only stall warning instrument.

2.11 Slip Indicator

The slip indicator works just like a water

level slip indicator.

2.12 User Selectable Data BoxesThere are 2 Data Boxes at the bottom of thedisplay. Each has four fields. Each fieldmay be either data or a label. The choicesare extensive ranging from GPS waypointsto engine parameters. Detailed instructionsare contained in the GRT Sport Set UpGuide (SET MENU, Primary Flight

Display, Data Boxes).

2.13 Fixed Data Boxes

There are 5 data boxes that display groundspeed or true airspeed in the upper leftcorner, Lateral Autopilot mode to top right of

airspeed tape, heading selection in the lowerleft corner, autopilot altitude selection orpresent altitude bug and Vertical Autopilotmode in the upper right corner and the

baroset in the lower right corner.

2.14 Trim, Flap G Meter Indicators

Aileron and pitch trim and flap positionindicators automatically display on the PFDpage in the lower left side. The data comesfrom EIS which can be configured for trimand flap position using its Auxiliary inputs.The G Meter will display in the same area. Itcan be selected to be always On, On when

a limit is exceeded or Off. Detailedinstructions are in the GRT Sport Set UpGuide.

2.15 Clock

If selected in the General Setup menu, adigital clock is displayed in the top rightportion of the PFD screen. The clockautomatically sets using GPS data and willshow either Zulu or user selected time.

2.16 Obstacle Warning

Obstacles such as towers are displayed onthe PFD that are within one minute of flightpath (based on current flight data (speed,direction)) and within 250 feet of theaircrafts altitude.

Sections 2.17 through 2.21 describe optionsthat are selected by the buttons under thelabels. See Section 1.2. To select optionswithin a particular group use the NEXTbutton. It helps to think about what it is youare trying to do then select the group thefunction may be in. Press NEXT for moreoptions.

2.17 PFD Lock

The locked selection disables the selectionof other display screens so that it isimpossible to inadvertently select a displaypage that does not show attitude, airspeed,altitude and heading information. Splitscreens that include the PFD informationmay still be selected. However, as you cyclethrough the split screens, when you reachthe full screen PFD you will be unable todisplay any split screen without unlockingthe PFD.

To select, press any button then NEXT

(more than once may be required) until PFDLOCK label appears. The button under thelabel will cycle PFD LOCK off and on.

2.18 NAV Mode

This setting selects the source of data that isused to provide navigation information to thepilot on the PFD and map pages as well asto the autopilot.

The selections provided will correspond tothe configuration of (what has been wired to)the system, such as internal GPS, externalGPS and VOR/NAV

The available Nav Mode selections areGPS1, GPS2, Nav1 and Nav2. Data sourcesmay be up to two GPSs (both external orone internal and one external) and twoexternal Nav sources. For example,GNS430 and SL30 (external GPS and twoexternal Nav) or Dual SL30 (two externalNav) or Dual GNS430 (two external GPSand two external Nav). A GPS selectionmay be the GPS side of the GNS430 andthe Nav selection may be the Nav side ofthe GNS430.

For example:

GPS1 (430 GPS)GPS 2 (Internal GRT GPS)Nav 1 (430 NAV-ILS/VOR)

Nav 2 (SL30)

The NAV mode is displayed in the upper leftcorner of the PFD display. Green is GPS,White is Nav 1, Cyan is Nav 2. Yellow isCaution / Input required / Mode not fullyengaged.

2.19 LAT A/P, VERT A/P, and ARM

LAT A/P and ARM will appear if Lateral

Autopilot Functions are ON (Settings Menu,General Setup). VERT A/P will appear ifVertical Autopilot Functions are ON and theEFIS is equipped with optional features.Their use is described in Chapter 5. IfLateral Autopilot Functions are OFF, thesebuttons will not appear.

2.20 Synthetic Approach

Synthetic Approach (identified as SAP)mode allows the GRT Sport to providelateral and vertical guidance to any runwaycontained with the EFIS navigation database(position data for each end of the runwaymust be in the database. The vast majorityof airports in the database have thisinformation). Vertical and lateral guidance isprovided via the highway-in-the-sky (HITS)on the primary flight display page andlaterally via the course and GPS cross track

deviation indicators. Lateral guidance isprovided for connected autopilots. Verticalguidance is provided for selected autopilotsand requires the Sport SX be equipped withoptional features. See Chapter 5.3.4 fordetails of using SAP with a connectedAutopilot.


27/91


Synthetic Approach provides the followingbenefits:

Enhanced situational awarenessduring all landings. Especially helpful

during night landings. Emergency means of guidance to the

runway for the VFR pilot whoinadvertently enters IFR conditions.

Redundant guidance during ILSapproach. The synthetic approachwill duplicate the ILS approachalignment but is based on differentdata (GPS and baro-alt vs. localizerand glideslope).

Emergency backup to ILS receiver.

Since the synthetic approach followsthe same path as the ILS and thispath has assurances of obstacleclearance, it could be used in anemergency when the ILS isunavailable.

Selecting SAP

To select Synthetic Approach mode, pressany button then NEXT (more than once may

be required) until the SAP label appears.The button under the label will selectbetween ARM and OFF.

Pressing ARM will result in a list of availablesynthetic approaches at the airport .in theflight plan if ALL of the following conditionsare met:

1. The last waypoint in the flight plan isan airport, and is contained within theGRT Sport SX navigation database,or an approach has been selectedand the GRT Sport SX is able todetermine the airport and runwaybeing used by the approach.

2. The database contains the necessaryinformation about this airport,

including runways, runwayorientation, position, elevation, etc.

3. AHRS, Air Data Computer and GPSdata are valid

The list of available synthetic approachesshows the runway identifier, the length,surface type (hard or soft), lighting, andcrosswind component.

The crosswind component is shown as X-Wind = speed L/R, where the speed is in theunits selected on the GRT Sport SX, and theL/R indicates a left or right crosswind, suchthat a left crosswind indicates the wind isblowing from left to right when on theapproach.

The GRT Sport SX will list the runways inorder of how closely aligned they are withthe calculated wind direction. Runways that

are predicted to have a greater than 10 mphtailwind are shown with a yellowbackground.

CAUTION: The pilot must not rely on thisdata for selection of the appropriaterunway. Wind speed and direction isusually different on the surface. The GRTSport is making its prediction based on itscalculated winds at the time the approachmode is activated. The accuracy of thewind calculation is affected by theaccuracy of the pitot/staticmeasurements, and the calibration of themagnetometer.

The desired runway is selected using the leftknob.

The selected runway will blink yellow on thePFD page.

After selecting a runway, a different runwaymay be selected using the SAP buttonagain. The label will now provide a ChgRwy option.

After selecting SAP and ARM, Checkbarosetting will be annunciated.

Once the runway and barosetting are set,

the HITS will appear if able. The HITS maybe behind, above or below depending onaircraft position relative to the runway.

If the selected runway includes anassociated localizer in the GRT Sport SXnavigation database, the messageSynthetic Approach using Loc Course

will be provided to remind the pilot that theapproach will follow the localizer, and maynot necessarily be aligned with the runwaycenterline.

If the approach mode is selected, but theGPS flight plan does not contain anapproach or an airport as the last waypointthat can be matched to the GRT Sport SXdatabase, then the synthetic approachcannot be activated. The GRT Sport SX willrespond with a message No Airport foundfor Synthetic App, and the approach modewill be turned off.

When the Synthetic Approach is enabled theheight above the runway will be displayedunder the Flight Path Marker in green. Thisaltitude will flash when below the DecisionHeight. The Decision Height comes fromdatabase approach information, if available.Otherwise, the Decision Height setting in theSET MENU is used.

Localizer Override

When the localizer is armed, or the NavMode is LOC, the synthetic approach modewill display the highway-in-the-sky but willnot provide steering nor autopilot coupling.This is indicated by DISP selection in theSAP softkey.

Synthetic Approach Path

Lateral steering will be constructedaccording to the following list in order of

priority:

1. If an approach has been selected onthe GPS, the synthetic approach pathwill match the course into the runwaywaypoint. (An approach is a flightplan that includes guidance to the

3.9 Navigation (Flight Plan)

The GRT Sport allows for quick and easyselection of a waypoint for Direct Tonavigation or a series of waypoints for

FLIGHT PLAN navigation. The use of thenavigation features provides:

1. Graphical representation on MAPpage (magenta for the segment youare currently on, white for segmentsplanned).

2. Display of waypoint in use andassociated data, such as range,bearing, ETA etc in data boxes ofPFD.

3. Output of steering information to

autopilot.

Flight Plans or Direct To waypoints may beentered into the Sport as described in thefollowing paragraphs. Both Flight Plans andDirect To waypoints require GPS data. GPSdata is provided either by the optionalinternal GRT GPS or by an external GPSincluding most panel mount GPS and manyhand held GPS.

If an external GPS is connected and theSport is configured for External Flight PlanSource (Set Up Menu, General), FlightPlans or Direct To waypoints that areentered in the External GPS will bepresented on the Sport Moving Map and thethree features described above will beprovided for the flight plan from the external

GPS. Since the GRT GPS is not certified forIFR use, this feature allows the use of anIFR certified GPS with the GRT Sport in IFRflight.
