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.

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.

New features include automatic runway identification, ability to predict how much runway will be used, runway over-run and low approach warnings and measurement of landing distance roll out.
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 (gethudly.com) 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.
