The first turboprop designed by Cessna, the Cessna Conquest II was meant to fill the gap between their jets and piston-engined aircraft. The 441 has the capacity for 1-2 pilots and 8-10 passengers. The empty weight is 5488 lb (2489 kg) and the gross weight is 10,165 lb (4611 kg). Cruise speed is 245 knots (282 mph, 454 km/h) and maximum speed is 260 knots (300 mph, 480 km/h). The rate of climb is 2435 ft/min (12.37 m/s). The 441 is a pressurized, turbine development of the Cessna 404. The aircraft was released in 1977.
The Cessna Conquest I has retractable tricycle landing gear and on takeoff has a ground roll of 1785 ft. The aircraft is powered by two Garrett TPE331 turboprops powering two four-bladed McCauley propellers. Modifications have been done to the majority of Cessna 441s. Garrett TPE331-10 engines have replaced most of the earlier versions of this same engine that the aircraft was delivered with. The engine modification reduces maintenance costs while increasing horsepower, service ceiling, fuel efficiency and range.
