1 FOREWORD Thank you for choosing the GRT EFIS! This manual describes the operation of a Horizon 10.1 and Sport 10.1 EFIS using the software version shown in the Record of Revisions. Some differences may be observed when comparing the information in this manual to other software versions. The Sport 10.1 EFIS may optionally be equipped with synthetic vision and vertical autopilot command capability.
*CAUTION*: Dual Nav radios tuned to Localizer frequencies with autopilot function ARM engaged will result in the EFIS Sport selecting either NAV radio to fly the Localizer. Sport/Horizon 10.1 Pilot’s Guide Rev. Preliminary...

GRT Avionics, Inc. September 2019 The Sport/Horizon 10.1 supports basic single screen panels as well as multiple screen redundancy using any combination of GRT EFIS systems, AHRS, and sensors, making it easy to grow your panel with your budget. Multiple-screen integration shares pilot inputs between screens and data that is only connected to one screen.
System (AHRS) to provide roll and pitch (attitude) reference and gyro heading slaved to magnetic heading (when a magnetometer is connected). The GRT Avionics AHRS features the ability to operate without external aiding from GPS or air data – a feature that preserves the integrity of this critical data even when air data or GPS is corrupted, and exclusive to GRT Avionics among experimental aircraft instrument manufacturers.
September 2019 4.3 Optional Components and Software EIS Engine Monitor The GRT Avionics EIS Engine Monitor provides all engine data to the EFIS. The Sport uses this data to drive its graphical engine display and compute additional engine performance information. The EIS is available with or without a display.
September 2019 GPS Receiver Compatibility The Sport/Horizon 10.1 is intended to be used with an external GPS receiver. The EFIS supports two inputs for redundancy. The external GPS can be a remote unit (no display), or a stand-alone GPS navigator that does allow the pilot to enter a flight plan. Practially all GPS receivers provide a serial output that is compatible with the EFIS.

In addition to the typical engine monitoring functions, the EFIS includes several engine monitoring functions that are unique to GRT Avionics. These are based on our extensive experience in this area. They are described in the “Enhanced Engine Monitoring” functions section below.
Engine data is displayed in various forms on the full and split PFD pages, full map page, and the engine/map page as shown in the following figure. Insets may also be used to show specific groupings of engine data as described in “5.4.6 MAP and PFD Insets” on page 27. Sport/Horizon 10.1 Pilot’s Guide Rev. Preliminary...

Bar Graphs – Up to 12 bar graphs can be configured. Up to 4 databoxes are also definable for the PFD/Plate split page. These databoxes are configured via the SET MENU > Graphical Engine Monitoring > PFD/PLATE Box 1 thru PFD/PLAT Box 4 settings. Sport/Horizon 10.1 Pilot’s Guide Rev. Preliminary...

Something as subtle as a single spark plug failing in cruise (which results in only the slightest engine vibration) are easily discernable as that cylinder’s EGT increases as much as 50 degrees. In short, EGT/CHT time histories, exclusive to GRT Avionics, are the only practical way to detect a large variety of developing engine problems.
