ADS-B Collision Avoidance System

INCAS - www.avmap.it 2

I. Introduction

The INCAS is a collision avoidance system designed for

general aviation and light sport aircraft. The INCAS is a

passive receiver of other aircraft’s transponders information. It

receives and decodes this information and displays the exact

position of all other aircrafts equipped with a Mode-S + ES or

ADS-B transponder. It also receives Mode-C transmissions

and displays the number of potential threats nearby.

II. Cautions & Warnings

• TheINCASisnotrecommendedasasubstituteforproper

trafc scanning procedures. This unit is intended as an

additionaltoolindeterminingpotentialtrafcthreats.

•NeverconnecttheunittoanACoutletortoanunknown

powersupplywithunknownvoltage.

•Donotconnecttheunitusingreversepolarity

•Donotexposetheunittherain,snoworanyliquid.Avoid

dusty,coldorhotenvironments.Avoidtheuseofchemical

agents when cleaning.

III. Connecting and powering the unit

Onthebackoftheunitthereare5connectors,thepower

supply connector, the ADS-B antenna connector, the

GPSantennaconnector,theaudiooutandtheexpansion

connector.

1. Power supply connector

Connect here the supplied cable with the cigarette lighter

cable adapter on the other end. Hardwiring the power supply

will require a dedicated 1A in-line fuse. For a permanent

installation please contact your local maintenance facility

for this operation.

2. ADS-B antenna

Do not use any type of antenna other than the one provided

with the unit. Otherwise performance of the unit might be

degraded.Makesurethattheantennaiswell fastenedto

theunit(ngertight).

3. GPS antenna

Connect here the active GPS antenna.

4. Audio output

Thisisastandard3.5mmjackconnector.Youcanplughere

apairofearplugs.Alternatively,forapermanentinstallation

inthepanel,animpedanceadaptercanbeusedtoconnect

this audio output the aircraft’s intercom. Please contact your

local maintenance facility for this operation.

5.Serial Port

The serial port is used for the optional FLARM module. The

FLARM module can be connected here in order to display

FLARM trafc information together with the Mode-S and

ADS-B information.

6. USB connection

TheUSBconnectionisusedforrmwareupdates.

Attention

The antennas should be placed on the glare shield of your

aircraft or close to one of the windows, without touching

the window. It is extremely important to position the ADS-B

antenna vertically and the GPS antenna with the top towards

thesky,notsidewayorupsidedown.

Powering on

To power up the Incas just connect the power supply,

andpushandholdforabout1secondthecenterknobon

the front. Incas will start up and its display will show two

roundcircles(20nmand10nmfordefault)andthetriangle

indicating your own position.

Powering off

TopowerofftheIncaspushandholdthecenterknobforabout

3 seconds. The display will show the message “shut down”.

IV. Reading the INCAS

The INCAS was designed with ease of use in mind. The unit is

veryeasytooperateanditwillworkrightoutofthebox.Just

connect the antennas and power and the INCAS will start up

anditwillshowsurroundingtrafc.

Whentheunitispoweredon,thedisplaywillshowtherange

circleswithasmalltriangleinthemiddle,theGPSstatus,the

NOPOSindicator,thehorizontalrangeandtheverticalrange.

The triangle

The triangle is your own position, updated 4 times per

second by the GPS.

Range circles

The two range circles indicate the distance from your own

positiontothemaximumdetectiondistanceconguredforthe

outer circle and half of that distance for the inner circle.

The default range setting when the unit is powered up is 20nm

(nauticalmiles).Thismeansthattheoutercircleisat20nm

fromcentre(ownposition)andtheinnercircleisat10miles.

The GPS Status

NOGPSmeansthataGPSxhasnotbeenacquired.GPS

OKmeansthatunithasavalid3DGPSxanditisready

tooperate.Pleasenote:aslongasNOGPSisshown,the

unitwillappeartobefrozen,itwillkeepsearchingforavalid

GPSxanditwillunlockassoonasaxisfound.

NOPOS indicator

This indicator shows the number of aircrafts around your

position which do not transmit valid position information

(Mode-C,Mode-SwithoutGPSandMode-A)

The Horizontal range (upper right corner)

Thisindicatorshowsthecurrenthorizontalrangesetforthe

device.Validrangeoptionsare5,10,20,40nm.

The Vertical range (lower right corner)

This indicator shows the current vertical range set. This

rangewillbeshownin3digits,theleastsignicantofwhich

indicates the hundreds of feet.

Trafc

Trafcwillbeshownonthedisplayasasmallicon,adotand

aline.Theiconis, yellow whenthethreat is mediumand

red when the threat is dangerous. The line represents the

heading(directionoftravel)ofthatparticularaircraft.Please

notethatitcantakeacoupleofcyclesfortheheadingtobe

updated and calculated correctly.

The threat icons will appear on the display as soon as the

threat enters the receiver’s range and it will be removed

fromthedisplay30–45secondsaftertheradiocontactwas

lost with that threat.

Nexttoeachtheaircrafticon,therelativealtitudeisdisplayed

(x100) and an up/down arrow indicating the vertical trend

(ascending/descending).

-10 means that the aircraft is at 1000 ft below your aircraft

+10 means that the aircraft is at 1000 ft above your aircraft

000 means the threat is at the same level as you.

V. Settings: changing the horizontal and

vertical range

Youcancustomizethewaytrafcisdisplayedbyusingthe

knobonthefrontofthedevice.Thereare2settingswhich

can be selected and changed, horizontal detection range

and vertical detection range.

Horizontal range:bychangingthehorizontalrangeyouwill

be able to see more distant aircrafts or to see more clearly

thecloseyingtrafc.Validvaluesforthissettingare5,10,

20,40nm.Theunit’sdefaultsettingis20nm.

Vertical range:youcancongureittoshowallairplanesor

onlyairplanesyinginsideadenedverticallayer.Theoption

is set in 2000 feet steps. This setting can be changed to show

aircraftsfrom2000ft.(020)tomaximum40000ft.(400).

The default settings show only aircrafts with a relative altitude

of+-6000ft(060)toyouraircraftposition.

Changethissettingto2000ft(020),todisplayonlyaircrafts

with a relative altitude of +-2000 ft to your aircraft position.By

changingthissettingtoe.g.3000ft(030),onlyaircraftswith

an altitude difference of +-3000 ft will be shown.

To select one of these options:

1.Press the knob and hold until the rst option (horizontal

range)issurroundedbyaredsquareandtheiconchanges

its colour to Red.

2.Turn the knob left or right to change the value of the

horizontalrange.

3.Whenthedesiredrangeisset,presstheknobagain,the

screen will be refreshed with the new settings and the

cursorwill nowmovetothenext option(vertical range).

This can also be changed if desired in the same way.
