The Cessna 411 is an American twin-engined, propeller-driven light passenger/cargo aircraft produced from 1962 to 1968. It was Cessna’s largest operational business aircraft equipped with two 340 horsepower Continental engines with three-bladed propellers.
In October 1964, production deliveries started. The Cessna 411 is an eight-seat low-wing cabin monoplane with two engines, retractable landing gear, and an airstair entrance door. The aircraft has an exterior length of 10.2 meters, a height of 3.52 meters, and a fuselage diameter of 1.6 meters. It has a wingspan of 12.15 meters, a wing area of 19 square meters, and a wheelbase of 3.06 meters. The cabin height is 1.3 meters, cabin length is 3.42 meters, and cabin width is 1.4 meters. Optional features provided for corporate configured aircraft included folding tables, a toilet, and a refreshment area.
The Cessna 411 is powered by two Continental GTSIO-520-C piston engines with three-bladed, constant-speed propellers. Each engine produces a rated thrust of 340 horsepower. It is a six-cylinder, horizontally-opposed engine with an overhead-valve, TCM fuel injection system, and air-cooling system.
The aircraft has a maximum speed of 233 knots at 16,000 feet and a cruise speed of 188 knots at 25,000 feet. At a speed of 188 knots, it can fly up to 25,000 feet with a range of 1,100 nautical miles. The service ceiling is 26,000 feet and the rate of climb is 1,600 feet per minute. The take-off and landing distances are 580 meters and 553 meters respectively. The maximum takeoff weight is 2,948 kg, the maximum landing weight is 1,973 kg, and the maximum payload is 975 kg. It has a maximum fuel capacity of 196 gallons.
The 411 was succeeded up by the 411A, and in 1967, it received its type certification. The 411A has a larger nose baggage capacity but with completely the same fuselage length. It is also equipped with optional tanks in engine nacelles for extra fuel capacity.
The aircraft was produced from 1962 to 1968. A total of two hundred and fifty-two 411 and fifty 411A were built. The French Air Force used the 411 for military operations. Six 411s were delivered from 1966 to 1969 as a communication aircraft, and the four remaining aircraft were deployed to the CEV in 1973 and 1974. Two aircraft were in service of the Groupe de Liaisons Aeriennes Ministerielles for VIP transport duties.
