The Cessna 310K: A Model of Performance and Comfort

The Cessna 310 series first took flight in 1953, setting a high standard for light twin-engine aircraft. By the time the 310K variant was introduced in 1966, the design had evolved into a sleek, high-performing aircraft with improved aerodynamics and payload capacity. The 310K brought refinements such as a higher gross weight, better fuel efficiency, and a more comfortable cabin layout.

Cessna, founded in 1927, built its reputation on designing aircraft that blend performance, reliability, and accessibility. The 310 series was particularly notable for its sleek fuselage, tip tanks, and capability to handle long cross-country flights. With a cruising speed of 179 mph and a range of 1,255 miles, the 310K model is well-suited for both personal and business travel.

One of the standout features of the Cessna 310K is its roomy six-seat cabin, which provides passengers with a more comfortable flying experience than many other twins of its era. The wide doors, ample legroom, and thoughtful layout make long trips more enjoyable for pilots and passengers alike.
