Butler National Corporation has received FAA STC approval (number ST02036WI) for the installation of the Garmin G700TXi flight display system glass cockpit into Learjet model 35/35A(C-21A)/36/36A aircraft with FC-530 or 535 autopilots.
The replacement of the traditional six pack of flight instruments (airspeed indicator, altimeter, ADI (including VG), HSI (including DG), vertical speed indicator/RA and RMI) with the Garmin G700TXi flight display and associated attitude, heading and air data sensors significantly enhances situational awareness and operations.
President and CEO Christopher Reedy says: “The Butler National team has placed a lot of time and effort into this Learjet glass panel upgrade, and the result is extremely nice. The displays offer tremendously enhanced pilot situational awareness. The autopilot interface for RNAV operations is seamless and intuitive, and decreases the traditional avionics workload and improves the pilot interface. Most of all, as a pilot, I greatly appreciate the well-organised and clear presentation of information on the Garmin G700TXi displays. While the effort has been significant, the result is extremely satisfying with the clean and user-friendly instrument panel.”
Carl Wolf, vice president, aviation sales and marketing at Garmin, adds: “Our TXi flight display system has been incredibly popular, and we're excited to have G700TXi in the Learjet model 35/36 series. Part 25 certifications are no simple task, and the efforts to achieve supplemental type certification and provide this upgrade to our mutual customers are appreciated by the entire Garmin team.”
Reedy adds: “Butler National, through its subsidiary Butler Avionics, plans to make the STC package available to Garmin dealers worldwide for field installation. We greatly appreciate the assistance of Garmin in achieving issuance of the STC. The STC applies to the Learjet model 35/36 series with FC-530 autopilots. Butler is now moving with the application of the G700TXi for the Learjet model 35/36 with FC-200 autopilots.”
