7 GENERAL IntroductionThis document provides the physical, mechanical and electrical characteristics and installationrequirements for the GRT HXr document, the HXr Set Up guide and the HXr Users guide make up the set of HXr userdocumentation. These documents, along with periodic software updates and other notices, areavailable at under the Support CertificationThe GRT HXr EFIS is not certified for Installation in FAA Type Certificated Aircraft. It is designedand intended for Installation in aircraft licensed as Experimental or System Description & ArchitectureThe GRT HXr EFIS (Electronic Flight Information System) consists of one or more panel mountedDisplay Units, one or more remotely mounted attitude-heading reference system (AHRS), and oneor two remotely mounted magnetometers.

8 The Display Unit is available with either a or screen. Dimensional drawings for both sizes, as well as the AHRS and magnetometer, are providedin the Appendix of this Manual . The HXr is available as either a 12 or 28-volt system; the voltageis specified on the data tag of the display AHRS packages are available. The Dual AHRS package (AHRS-2) is standard with thedual-display system, while the single AHRS (AHRS-1) is standard with a single display. The DualAHRS is two identical AHRS units inside one module; this assures that both AHRS units are alignedwith each other at all times. Dual AHRS is available with a single screen system as an most basic configuration for HXr is a single EFIS screen to display the primary flight instrumentsof airspeed, altitude, heading, attitude, vertical speed, and rate of turn.

9 To do this, the EFIS displayunit works with a remotely-mounted attitude-heading reference system, or AHRS, and amagnetometer unit to determine aircraft attitude and heading information. The air data computer,located inside the AHRS box, is connected to the aircraft pitot/static system to determine airspeedand altitude. The GRT AHRS is unique in the industry in that it provides attitude data without gyros,GPS or pitot/static input to compute aircraft attitude, making it more reliable than systems thatrequire external GPS is added to the system, GPS track and a moving map are displayed on the map pageof the primary display or the secondary display if equipped.

10 GRT offers several different GPSmodules for the HXr. A third-party GPS unit may also be used, such as a Garmin 430/530 or Garmin650/750. This feature is useful for adding IFR GPS approach capability to the HXr system. (IFRapproach sequencing is currently in development at GRT.) Note that the only GPS functions thatHXr Installation Manual GRT Avionics1-8 Revision A5import from a third-party GPS to the EFIS are track and position. Flight plan sequencing from sucha GPS can be imported if the GPS is wired to the EFIS through the ARINC 429 the Grand Rapids Technologies Engine Information System (EIS) unit is installed in the aircraft,every engine parameter imaginable is able to be monitored through the EFIS system.
