Learjet 35/36 operators have an RVSM option thanks to Butler National subsidiary Avcon Industries, which has received FAA approval to install its next-generation RVSM equipment in Learjet 35s and 36s equipped with the FC-200 autopilot.

“This approval makes the Avcon RVSM supplemental type certificate the most comprehensive in the industry covering the Learjet 24, 25, 28, 29, 35 and 36,” said company president Larry Franke. “The Avcon Learjet 35/36 RVSM solution will allow airplanes to operate with reduced vertical spacing at altitudes of 29,000 through 41,000 feet. It will also allow interface with the most advanced glass-panel cockpit display systems. There are more than 200 Learjet 35s and 36s flying without RVSM and we’ve already received RVSM orders for delivery in the second and third quarters of this year.” Avcon has installed the Avcon RVSM solution on more than 130 Learjet 20-series airplanes and other RVSM solutions on a number of Learjet 35/36s.
