CESSNA 182

Development

The Cessna 182 was introduced in 1956 as a tricycle gear variant of the 180. In 1957, the 182A variant was introduced along with the name Skylane. Later models have added more powerful engines and bigger windows.

Cessna cites the 1990s resumption in producing general aviation aircraft such as this model due to change in U.S. liability laws. In 2005, Cessna began offering the Garmin G1000 glass cockpit as an optional upgrade to the Skylane. Subsequently the glass cockpit became standard equipment.

Design

The Cessna 182 is an all-metal (mostly aluminum alloy) aircraft, although some parts – such as engine cowling nosebowl and wingtips – are made of fiberglass or thermoplastic material. Its wing has the same planform as the smaller Cessna 172 and the larger 205/206 series; however, some wing details such as flap and aileron design are the same as the 172 and are not like the 205/206 components.

Retractable Gear

The retractable gear R182 and TR182 were offered from 1978 to 1986, without and with engine turbocharging respectively. The nomenclature is confusing, as smaller Cessna singles with optional retractable gear are called "Number"RG (eg 172RG, 177RG), and one sometimes reads or hears of "182RG" in error. However, Cessna called the R182 the "Skylane RG". The R182 and TR182 offer 10-15% improvement in climb and cruise speeds over their fixed gear counterparts (or, alternatively, 10-15% better gas mileage at the same speeds) at the cost of increased maintenance costs and decreased gear robustness.[citation needed] The 1978 R182, for example, has a sea level climb rate of 1140 fpm and cruising speed (75% BHP) at 7,500 feet (2,300 m) of 156 KTAS at standard temperature.

The landing gear retraction system in the Skylane RG uses hydraulic actuators powered by an electrically-driven pump. The system includes a gear position warning that emits an intermittent tone through the cabin speaker when the gear is in the retracted position and either the throttle is reduced below approximately 12" MAP or the flaps are extended beyond 25 degrees. In the event of a hydraulic pump failure, the landing gear may be lowered using a hand pump to pressurize the hydraulic system. There is no alternative procedure for retracting the landing gear.
