Overview

The Mini with three main goals in mind:
  • A small, lightweight, economical VFR EFIS system for LSA and light kitplanes
  • An affordable, high-quality backup to our larger EFIS systems for IFR operations
  • A stand-alone autopilot and backup flight instrument all in one.
As an IFR backup flight instrument, the Mini-X and Mini-AP can do what no other brand of backup display can do for GRT Horizon and Sport users:
  • Serve as an auxiliary autopilot control head for GRT servos that maintains an independent source of control if the main display unit should fail.
  • Utilize the same pilot interface as the popular Horizon and Sport series, meaning you will not have to remember a different brand’s “buttonology” in an emergency.

Specifications

  • OAT, TAS and Density Altitude are displayed when the Mini is connected to a GRT EFIS or with the optional OAT sensor.
  • Li-Ion battery for Mini-AP does not power the servos. (Servos require a significant amount of power.)
  • EFIS Serial Link is limited to a few key items TBD.
  • Autopilot controls for Mini-X do not include vertical guidance for IFR approaches. This feature is included with Mini-AP when equipped with ARINC-429 wired to a suitable IFR GPS navigation unit.
  • Control of the Trig TT22 remote transponder is supported.
