Introducing the GRT Mini...
Thanks Brian & Chuck,
A lot of info can be found
here. The template for mounting is linked on the bottom of the page. The vertical and horizontal cutout dimensions will be the same as that listed, but the depth of the machined aluminum case may still increase a bit as we finalize everything. Pitot/static lines will enter the back of the unit, as well as the D-sub connector and optional plug-in backup battery. The AHRS is internal and independent of the main EFIS.
As far as external modules, the Mini-B "backup" is all self-contained, except for the included GPS antenna (the same we currently use for our EFIS GPS). The Mini-X (adding synthetic vision and basic autopilot control) and Mini-AP can have a remote magnetometer so they can use magnetic heading instead of a GPS derived track/heading. This is included on the AP and an option for the X (included through the end of April 2014).
The Mini-AP will have built-in ARINC 429 for interface with Garmin IFR GPS units, so it functions like an independent autopilot with flight instruments and a moving map. The GRT autopilot can be controlled by either the full-sized EFIS or the Mini-AP with a flip of a switch. When equipped with GRT servos, the Mini-AP can also function as an autopilot and backup EFIS in aircraft with a primary EFIS system of a different brand.
The price for the Mini B is $995 through the end of April 2014. The Mini X and AP are more-- I'll have a pricing and features comparison chart on the Mini web page in the next day or so.
We are anticipating production to ramp up for the Mini-B after Christmas. Pre-orders for all 3 Mini models are now being taken with no deposit required.
We're very excited about the Mini. In airplanes where panel space is at a premium, such as the RV-8, it provides a great backup flight instrument option for IFR redundancy. It is a solution for pilots who like the GRT autopilot, but prefer a control head independent of the primary EFIS. Plus, it has the same basic pilot interface as our other EFIS systems, something you don't want to think twice about during an emergency.
More information will be posted on our website soon, including basic wiring schematics and a feature/pricing chart.
