About the Cessna 152

The Cessna 152 is the world's most ubiquitous two-seat trainer, a refined successor to the already-legendary Cessna 150 that dominated flight schools from its 1977 introduction through 1985. Cessna built 7,584 examples in those eight years, and the type remains the backbone of primary flight training across North America, Europe, and Oceania decades later. Its 110-horsepower Lycoming O-235 engine, tricycle landing gear, and docile handling make it nearly ideal for ab-initio students, while its modest operating costs keep it economically viable for flight schools even as fuel prices climb.

The 152's design is deliberately forgiving: full-span flaps, a wide center of gravity envelope, and benign stall characteristics that tolerate ham-fisted student inputs without drama. Maximum structural cruising speed sits at 111 knots, never-exceed at 149 knots, and stall speed in landing configuration is a gentle 35 knots, slow enough that most instructors can demonstrate a power-off approach over the fence at walking pace. The type's longevity is a testament to Cessna's engineering pragmatism: the airframe is simple enough that a rural A&P can maintain it with hand tools, parts remain widely available, and the aircraft's reputation for surviving hard landings has made it a durable asset for training operations that cycle through hundreds of students per year.

SkyMeter has tracked flights across airframes and operators, with the largest observed operator.
