The attitude andheading reference system(AHRS)is agyro reference system that generatesangularrateandlinear acceleration information aboutthe aircraft axis.
The AHRSis adualsystem withtwo independentattitudeandheading computers. Each computer receives correctedheadinginformation from anindividualflux detector which sense the earth’s magnetic field. Each computeralso receives information from thesame sideairdatasystem. This information,together with accelerometer sensordata,is processed and senttothe integrated avionics processor systemwhichinterfaces withthe flight controlcomputers andflight management computers.
These signals are also routedto the TCAS,GPWS, weatherradar, fuelsystem, stall protection system, flightdata recorderanddata concentratorunits.

AHRSprovidesattitudeandheadinginformation tothe electronic flightinstruments. The PFD’s displayAHRSalignmentflagsduringinitialization (30to70 seconds). Ifaircraft primarypower islost, the AHRSwill continue to operate on batterybuspower for11 minutes. Attitudeis displayed on theattitudedirection indicator(ADI)oftheprimaryflight displays andheadingis displayed on thehorizontal situation indicator(HSI)portions ofthe displays.
AHRS mode selections are made usingthepilot or copilot compass controlpanel. The AHRS normallyoperatesin magnetic (MAG) mode. Directionalgyro (DG) modeis intended tooperate as a heading reference,onlyforashortperiod oftime, nearareas where magnetic disruptions existanddoesnot use datafrom theflux detector.
Aslew switchis providedto changeheadingdirection. The switchis operationalin both MAGandDG modes. In DG modeitis usedperiodicallyto correctfordrift. InMAG mode,it also causes theheadingto slew in theselecteddirection. Whenthe switchis releasedin MAG mode,theheadingwillslowlyslave backto the headingdefinedbytheflux detector.
