However,itisimportanttonotethatC.A.T.doesnotautomaticallyavoidcollisionswithall
obstaclesinallconditionsandcircumstances.Factorsincludingthematerial,sizeandshape
ofanobstacle/object,itspositionandanglerelativetothesensor(s)andthespeedthe
helicopteristravelingatcanhaveanimpact
ondetectionandthecorrespondingresponse.

Forexamplethetechnologywillbestdetectobstacles/objectswithsurfacesmadefrom
materialsthatbetterreflectultrasoundwaves.Suchobstacles/objectscanincludesome
walls,uncoveredwindows,furniture(cabinets,bookcases,desks,etc.)andothers.
Obstacles/objectswithsurfacesmadefrommaterialsthatcanabsorbultrasoundwaves,
includingsomefabriccoveredfurniture,windowcurtains/drapes
andothers,willbemore
difficulttodetect.Onepotentialwaytodeterminehowwellaparticularobstacle/objectcan
bedetectedistofollowthetestprocedureoutlinedinthe‘C.A.T.Testing’section.

Otherfactorscanalsohaveanimpactondetectionandthecorrespondingresponseofthe
technology.Someofthesefactorscanincludetheobstacle’s/object’ssizeandshapeaswell
asitspositionandanglerelativetothesensor(s).Forexamplethe‘smaller’thesurfaceofan
obstacle/objectisrelativetothe
sensor(s)thelesslikelyitistobedetectedunlessit’smore
‘directly’infrontofthesensor(s).Also,thesensorswilltypicallybetterdetectan
obstacle/objectwhenthefront(thesidewiththe‘meshscreen’)isasclosetoparalleltothe
surfaceoftheobstacle/objectaspossible.
However,thesensorscanstilldetectsome
obstacles/objectsevenwhentheyarenotdirectlyinfrontofand/ornosurfacesareparallel
tothesensors,albeitatlimited/lessrange.

Anotherimportantfactortoconsideristhespeedatwhichthehelicopteristravelingtoward
anobstacle/object.Thefasterthehelicopterismovingthelesstimethetechnologywillhave
todetectandrespond.Evenwhenanobstacle/objectismadefromamaterialthatbetter
reflectsultrasoundwaves,andhasa
relativelylargesurfacethat’spositioneddirectlyinfront
ofandparalleltothefrontofthesensor(suchasawall),ifthehelicopterismovingtowardit
tooquicklythetechnologymaynotbeabletodetectitandrespondintimetohelppreventa
collision.Itis
typicallyrecommendedtousethe‘Low(LO)’controlratesettingonthe
transmitterand/orminimalcontrolinputstokeepthehelicopterfromtravelingtooquickly
towardobstacles/objectswheneverpossible.

TurningC.A.T.OnandOff

TheadvancedC.A.T.softwareoffersselectablemodessuitableforflyinginlargerandsmaller
indoorspaces(seethe‘HIandLOModeSettings’sectionformoreinformation)andalso
makesitpossibletoturnthetechnologyonandoffremotelyfromthetransmitteratany
time.WhenusingtheMP5Htransmitter
includedwiththeRTFversionthe‘GEAR’(channel5)
switchlocatedonthetopleft‘shoulder’willturnthetechnologyon/off.Whentheswitchisin
the‘0’position(towardthebackofthetransmitter)thetechnologywillbeOFF.Whenthe
switchisinthe‘1’position(towardthe
frontofthetransmitter)thetechnologywillbeON(as
indicatedbythebluecolorLEDthatwillilluminatetheinsideofthecase/housingforthe
C.A.T.moduleanytimethetechnologyisturnedON).
