Cessna 172 Skyhawk: a design story behind the most-built light aircraft

The Cessna 172 Skyhawk has a silhouette many people recognise even if they have never flown. High wing braced by struts, swept vertical tail, fixed tricycle undercarriage: for plenty of casual observers, that is simply what a small aircraft looks like.

Not everyone rates it on looks. Some argue the aircraft remembered longest tend to be the most attractive, and they place the Skyhawk outside that group. Judged instead against the principle that form should follow function, the type makes a strong case for lasting success. Its commercial record is tied closely to the way it is shaped.

The 172 first flew in 1955 and marked a shift in general aviation, partly through its design and partly through how it was sold. It arrived as the industry was moving away from tailwheel landing gear toward tricycle gear, though it was not the first to make that change; the Piper Tri-Pacer and other designs came earlier. Nor was the 172 a radical departure.

What set it apart was all-metal construction, solid performance, a pleasing appearance, and advertising that pitched it as simple to bring down onto a runway. Production has continued, and more than 44,000 examples have been delivered, making it the most-built light aircraft.
