About the Cessna 180 Skywagon

The Cessna 180 Skywagon is one of general aviation's most beloved taildraggers, produced from 1953 to 1981 and prized for its rugged construction, short-field performance, and go-anywhere versatility. Unlike its nosewheel sibling the Cessna 172, the 180 features conventional landing gear and a more powerful engine (originally a 225-hp Continental O-470, later upgraded to 230 hp) paired with a constant-speed propeller that gives it exceptional climb rate and load-carrying capability. Bush pilots in Alaska, Canada, and the Mountain West have long favored the type for backcountry strips, floatplane operations, and cargo hauls where paved runways are a luxury.

The 180 can operate comfortably from grass, gravel, sand, and improvised strips as short as 600 feet, and its high-wing design provides excellent visibility and ground clearance for oversized tundra tires or amphibious floats. With a useful load around 1,100 pounds and a cruise speed near 140 knots, the Skywagon strikes a practical balance between payload and speed that few single-engine aircraft match. Though production ended four decades ago, the type remains in wide service across North America, supported by a strong parts network and a passionate owner community.

Many airframes have been meticulously maintained or restored, and the 180's reputation for durability means thousand-hour overhauls and multi-decade service lives are common. SkyMeter has tracked flights across airframes and operators over routes, with the largest observed operator.
