Aircraft model
CESSNA 310K
Everything here is true of every aircraft of the type, not of any one aircraft.
The 1966 Cessna 310, with a higher gross weight and the IO-470-V engines that served the rest of the normally aspirated run. It carries nearly 2,000 lb, seats six and cruises at 190 knots, which makes it a genuinely useful business and family twin.
The 310 has always been fast for its power because the airframe is clean, and the canted tip tanks that look like styling are actually doing aerodynamic work. The costs are the usual twin costs and the risk is the fuel system, whose cross-feed and tank-sequencing rules have caused accidents. Two IO-470s and two propellers to overhaul, plus a light-twin annual. Insurance requires a multi-engine rating and, for most owners, recurrent training.

- Each of the five categories places the model within its peer class, from 0 (the worst of the class) to 10 (the best): a position among comparable models, not a grade. The overall score is the sum of the categories shown that are scored, out of 10 for each (50 when all five are); it is given only when at least 4 of the five are scored, and it can be set against another model's only when both are in the same peer class and scored on the same categories.
