Textron Aviation is opening the order book for its new large-cabin Citation Hemisphere.

The company has received interest in the $35 million aircraft, its largest to date, from large fleet operators, corporate operators and individuals, according to Rob Scholl, Textron Aviation senior vice president of sales and marketing.

A decision on whether to build the jet at the company’s west facility in Wichita or inside the former Beechcraft campus on the city’s east side has not been made.

The Hemisphere is a new market for the company and a natural one in which customers can move up into the large aircraft, said Scott Ernest, Textron Aviation president and CEO.

First flight is scheduled for 2019. The aircraft will include Honeywell avionics, Safran Silvercrest engines and three cabin zones, and will have a maximum range of 4,500 nm with four passengers and a Mach 0.90 maximum speed.
