The Cessna 172 Skyhawk is an American four-seat, single-engine, high wing, fixed-wing aircraft made by the Cessna Aircraft Company First flown in 1955, more 172s have been built than any other aircraft. The Cessna Skyhawk is the ultimate training aircraft and the most popular single-engine aircraft ever built. With forgiving flight characteristics, great visibility, a sophisticated glass cockpit outfitted with G1000 avionics, slow landing speed and a forgiving stall - the Cessna Skyhawk is a flight training favorite ideally suited for student pilots.
Measured by its longevity and popularity, the Cessna 172 is the most successful aircraft in history. Cessna delivered the first production model in 1956 and as of 2015, the company and its partners had built more than 44,000. The aircraft remains in production today.The Skyhawk N, or Skyhawk/100 as Cessna termed it, was introduced for the 1977 model year. The "100" designation indicated that it was powered by a Lycoming O-320-H2AD, 160 horsepower (119 kW) engine designed to run on 100-octane fuel, whereas all previous engines used 80/87 fuel. But this engine proved troublesome, and it was replaced by the similarly rated O-320-D2J to create the 1981 172P.
The 1977 "N" model 172 also introduced rudder trim as an option and standard "pre-selectable" flaps. The price was US$22,300, with the Skyhawk/100 II selling for US$29,950.
The 1978 model brought a 28-volt electrical system to replace the previous 14-volt system. Air conditioning was an option.
The 1979 model "N" increased the flap-extension speed for the first 10 degrees to 115 knots (213 km/h). Larger wing tanks increased the optional fuel to 66 US gallons (250 l).
The "N" remained in production until 1980 when the 172P or Skyhawk P was introduced.
