Rev D – Added description of use of Android compute stick loading and configuration.
Mini Software Version 4.02 (1/23/2018)
- Fix false roll/pitch trim required warnings from non-controlling unit by detecting which unit is controlling the GRT servos.
New setting in A/P Maintenance, Controller Number, sets controller. Set to 1 for the primary controller and 2 for the backup controller. Auto uses the display link ID
- Add data to the Bluetooth link to support future PFD/HUD graphics
- Don’t show vertical speed if the altitude is marked invalid
- Add support for CO Guardian and Life Guardian
- Automatically acknowledge temporary warnings from echoUAT TMAP after 10 seconds, and ignore false warning flags
- Hide ADS-B status lines that aren’t supported by the connected receiver
- Hide SPC Input Counter when configured for echoUAT TMAP, it doesn’t count in this mode
- Fix loss of external magnetometer heading when a remote air data module and an external magnetometer are connected to separate ports and the magnetometer is not connected to the air data module

The latest release of the GRT Remote app provides greatly enhanced HUD functionality, including full support for augmented reality mode. This mode points out the runway to you, with outlining of its runway edges, and a flight path marker that are shown referenced to the outside world.
Among the new functionality:
- Augmented Reality Mode and Condensed Mode fully supported
- Highway-in-the-Sky approach guidance
- Runway outline
- Enlarged HSI with heading bug
- Course capture – HSI enlarges, moves to center, and shows ground path prediction
- GPS Goto Waypoint display with selectable distance and ETA
- Height above runway
- Inverted projector mounting option
- Improved automatic runway detection
- Verified full functionality with $30 Android compute stick MK809 III with auto-startup

Development continues…stay tuned for the latest!
Mini-X and Mini-AP models now include the engine page and bluetooth capability (dongle required), the “Feature Set” is no longer required! Also, the Moving Map option now includes ADS-B display when connected to an ADS-B receiver.
The latest Heads-Up Display by Hudly, the Hudly Wireless, will be directly supported by GRT Avionics. Our approach to driving after-market Heads-Up Displays(HUD) allows for full functionality of this HUD as well as display optimization using existing user settings. We will evaluate this display when it becomes available for possible optimizations and recommendations to our customers.
The approach phase of flight requires a lot of concentration and there are many opportunities for mistakes to occur. Shallow approaches, coming in too fast or slow, running off the end the runway or even landing on the wrong runway can easily happen. The GRT Heads-Up Display provides valuable information, guidance and warnings without having to look down at a PFD and then re-focus your vision, read the display, look back out the window and re-focus your eyes again. The most important flight data is continually before your eyes as you look out the window along your approach path.
In many ways, the Heads-Up Display obsoletes traditional panel mounted instrumentation, providing a more natural way to stay aware of your approach. Lets take you through a typical approach… Read more
The GRT Avionics Safe-Fly GPS has been added to the available menu selections for GPS position source when requesting an FAA Public ADS-B Performance Report.
October 19, 2017
To: GRT Customers
As a result of the problems encountered by Navworx with regard to their GPS performance, I, Greg Toman, chief engineer and owner of GRT Avionics, contacted Ken Heusser of the FAA Aircraft Compliance Office (ACO) in Fort Worth, TX, in January of this year to inquire about any possible compliance issues with respect to the GPS requirements in FAR 14 CFR 91.227 for the Safe-Fly GPS being developed at that time.
In my conversation with Mr. Heusser regarding this issue, I was assured that the GPS source we had selected was approved by the FAA and met the requirements of 14 CFR 91.227 regarding the GPS performance. Mr. Heusser was immediately familiar with this device, and FAA approval is documented in the datasheet describing it. Mr. Heusser recommended that we retain a copy of this datasheet, and reference this part in our internal documentation, which we have done. He further indicated that no formal written approval was required.
Further to meeting the spirit of the FAR, we provided a mechanism to update the software in our processor that is used to transmit this GPS data in the event we introduced any software fault. This mechanism functions without the removal of the GPS when it is connected to a compatible GRT EFIS. To date, no software bugs have been found.
To conclude, I am confident our Safe-Fly GPS is suitable GPS source for any ADS-B output device described in the Safe-Fly GPS manual.
