AvMap Incas User manual

  • Hello! I'm here to help you understand the AvMap INCAS collision avoidance system described in this user manual. I've analyzed the document and am ready to answer your questions about its features such as transponder information display, configurable range, and barometric altimeter. Just ask!
  • What type of aircraft is the INCAS designed for?
    What does the INCAS display?
    How do I power on the INCAS?
    What are the options for horizontal range?
    What is the vertical range adjustment?

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.

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
veryeasytooperateanditwillworkrightoutofthebox.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maximumdetectiondistance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).Thismeansthattheoutercircle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.

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cancongureittoshowallairplanes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.
