Bad weather is bad business. That's especially true if you're an airline or commercial pilot, though it impacts everyone. Weather-related delays and cancellation tax the economy for billion of dollars in lost productivity each year, much of which is borne by the airlines themselves. And of course there's the occasional human cost of weather as well. Every so often, a rapidly forming weather event or a bad decision by a pilot costs lives.
There was an unusual visitor at the Oshkosh airshow this year: a roadable aircraft manufactured by PlaneDriven. The PD2 takes a Glasair Sportsman amateur-built airplane and adds a separate 50-hp “drive unit” to the rear of the craft to provide ground power. To put the vehicle into drive mode, the pilot folds the wings, starts the drive unit, and away we go.
