Updating older aircraft to “better than new” has become big business, and Butler National Corporation's (Booth No. 3196) just announced STC for the installation of the Garmin GTN 750 nav/comm into Learjet 35 and 36 series aircraft should make a few NBAA’12 Convention attendees sit up and listen.

The GTN 750 is a fully integrated GPS/NavCom/MFD solution with Waas GPS capability. The six-inch tall system’s touchscreen controls and large display give the pilot access to high-resolution terrain mapping, graphical flight planning, geo-referenced charting, traffic display and multiple weather options. The Butler STC includes GPS roll-steering for turn-anticipation and waypoint sequencing interfaced to the aircraft's autopilot.

“The STC for the new Garmin GTN series allows us to tap into a sizeable upgrade market for retrofit of flight management systems,” said Craig D. Stewart, president and CEO of Butler National Aerospace. “The installation is cost-effective for various Learjet operator requirements,” he continued.

The STC will be offered through Butler National's avionics facility, Kings Avionics, located at Salt Lake City International Airport in Utah. It is expected to cost less than $100,000.
