Butler National Corporation, which specializes in the aerospace sector of structural modification, maintenance, repair, and overhaul, announces issuance of the Supplemental Type Certificate (STC) for installation of the new Garmin GTN series of navigators that provide GPS, navigation, and communications. The installation is for GTN 750 navigators in the Learjet Models 35/35A/36/36A with the FC-200 autopilot and the Learjet Model 24.
The Garmin GTN series features intuitive touchscreen controls and a large-screen display that give Learjet pilots unprecedented access to high-resolution mapping, graphical flight planning, and geo-referenced charting, among many other features. The installation also features new GPS roll-steering that allows seamless navigation operations with turn anticipation and waypoint sequencing interfaced to the autopilot.
“This approval offers a significant and economical avionics upgrade for the Lear 30 series airplanes,” said Clark Stewart, president and CEO of Butler. “The STC for the new Garmin GTN series allows us to tap into a sizeable upgrade market for retrofit of flight management systems. The Garmin GTN upgrade provides significant functionality upgrades, including WAAS GPS approaches and roll-steering interface to the autopilot.”
“We have designed the installation to provide cost-effective options to meet the various Learjet operator requirements. We will be offering the GTN Learjet installations through our avionics facility Kings Avionics starting under $100,000,” commented Craig Stewart, Aerospace division president.
