The Mini is not a compromised instrument. It is a complete EFIS capable of synthetic vision, with a GPS navigator, incorporating the same technology that made GRT famous with its high-integrity AHRS. It is completely suitable as the primary instrument in your panel or as a backup for attitude, heading, track, airspeed, altitude and VSI. Highly readable airspeed/altimeter tapes and rotating drum-style digital display. Free database updates for all US territories. Simple installation – connect power, ground and mount the GPS antenna on your dash. Incorporates a full AHRS solution (internal) that does not require GPS or air data to provide attitude data.
and wiring harness.
As A Primary Flight Display
The Mini includes an electronic attitude source (AHRS) that is not dependent on GPS and/or air data. IFR certifiable altitude, vertical speed, and airspeed are boldly shown with tapes and smoothly rotating drum-style digital displays that instinctively convey value and trend. Internal or external GPS navigation and steering data is provided on the PFD, and highway-in-the sky guidance to any runway in the database. The addition of the external magnetometer adds heading and winds.
The primary flight display screen terrain showing relative height. In the upper left the autopilot/flight director mode is shown as synthetic approach to runway 35. The flight director is commanding a slight pitch down in the center of the screen. The airspeed and altimeter drums move smoothly and the high-contrast digits make them highly readable. Extending up from the runway is the way-point balloon.
Optional Moving Map
The moving map has the features you would only expect to find in a full EFIS. It includes such features as terrain relief, relative terrain height color coding, nearest functions, airport details including frequencies and runways, and much more. When connected to an external GPS, its flight plan and steering information can be displayed on and drive the map.
Smooth Rotation Moving Map
Hand-held or panel mount GPS navigators update their display once per second. Some EFIS based moving maps do same. The result is a jerky and delayed map. The Mini combines AHRS and GPS data to update its map at up to 15 times per second, resulting in a smoothly rotating map. Rolling out of a turn precisely on track becomes easy and the extended runway centerlines eliminate the guess work, making navigation easier and more precise.
When equipped with the optional moving map, the Mini-X extends its role by coupling to other navigation sources, such as navigation radios. The Mini includes and OBS (radial) selector for VOR or LOC/ILS navigation. Lateral and vertical deviations are also displayed on the primary flight display.
Angle-of-Attack (AOA) Sensing/Stall Warning
Angle-of-attack sensing is available as an upgrade on the Mini-X. Sensing is via a two-port 45 degree pitot tube, such as those commonly available from a variety of manufacturers, or using a probe fashioned by the builder. This method has no moving parts, and allows the use of heated pitot tubes that preserve the stall warning function even in the presence of icing.
The GRT Avionics AOA function drives on-screen AOA symbology that shows too fast/too slow/optimal approach speeds, as well as stall warning. In addition, an audio output is provided on the Mini-X. This audio provides an approaching stall warning annunciation (a pulsating tone that varies with proximity to the stall warning angle) and a solid tone indicating stall is imminent.
Practically identical to the engine monitoring provided by our larger EFIS systems, the Mini-X engine monitoring provides 6 engine pages, percent power calculation, and GRT exclusives (such as the EGT and CHT time histories and engine efficiency via the specific fuel consumption display).
Probably the most popular of the engine monitoring screens is the EGT time history page. In addition to two user-programmable dials, fuel management, and basic engine data. This screen includes a 2-minute history of all EGTs. This GRT exclusive allows you to effortlessly distinguish between engine problems affecting one cylinder or the engine itself. It also makes it easy to see small changes in engine operation that might not otherwise be noticeable. Even better, this display provides reassurance that your engine is running normally, especially when flying over water or at night. If the EGTs are steady, so is the engine.
Real-time traffic and weather is now a practical reality, and it is fully supported by the Mini. Unlike a tablet, the Mini’s screen is always readable, remains fully controllable in turbulence, and doesn’t suffer from overheating problems.
NexRad Weather Radar
- METAR data, and terminal area forecasts available on details page
- Airports color-coded based on METAR data
- TFR (Temporary Flight Restrictions) graphically and with text descriptions
- Real-Time Traffic (requires ADS-B Out to assure traffic is provided to your airplane)
Control Radios and Flight Plans with Your Android Phone or Tablet…
Install an optional Bluetooth dongle and connect with your Android phone or tablet using our GRT REMOTE App for Android*. Control tuning of your connected radios, create & edit active flight plans, and view the flight instruments all on your Android tablet or phone–perfect for the backseat co-pilot. The radio tuning portion of the app offers so much information, you may not want to tune them without it!
Integrates With Other GRT Equipment
The Mini-X adds automatic cross-checking of its attitude with any GRT EFIS screen. The GRT EFIS flight plan is displayed and may be edited on the Mini-X. Baroset and dimming is shared. In short, it adds another screen to your GRT equipped panel with complete integration via the inter-display unit link.
Heads-Up Display Capable
A heads up display can now be part your your GRT Avionics equipped airplane for as little as $300. Our pursuit of heads up display technology has led to support for the Hudly automotive after-market heads up display. Graphics optimizations in the GRT remote app, combined with the impressive readability and value of the Hudly have resulted in the first practical heads up display for experimental and general aviation (certified) airplanes.
