Hints:
FAA
Transition
lbs.
cobblestones
gearbox
The flight testing that followed that was as basic and low-risk as we could make it, but it still accomplished what we needed to to take the program to the next step and to gain the credibility that we needed within our eventual market, the general aviation community, and with the regulators that govern the use of design of aircraft, particularly in the States. The FAA, about a year ago, gave us an exemption for the Transition to allow us to have an additional 110 lbs. within the light sport aircraft category. Now that doesn't sound like a lot, but it's very important, because being able to deliver the Transition as a light sport aircraft makes it simpler for us to certify it, but it also makes it much easier for you to learn how to fly it. A sport pilot can be certificated in as little as 20 hours of flight time. And at 110 lbs., that's very important for solving the other side of the equation -- driving. It turns out that driving, with its associated design implementation and regulatory hurdles, is actually a harder problem to solve than flying. For those of us that spend most of our lives on the ground, this may be counter-intuitive, but driving has potholes, cobblestones, pedestrians, other drivers and a rather long and detailed list of federal motor vehicle safety standards to contend with. Fortunately, necessity remains the mother of invention, and a lot of the design work that we're the most proud of with the aircraft came out of solving the unique problems of operating it on the ground -- everything from a continuously-variable transmission and liquid-based cooling system that allows us to use an aircraft engine in stop-and-go traffic, to a custom-designed gearbox that powers either the propeller when you're flying or the wheels on the ground, to the automated wing-folding mechanism that we'll see in a moment, to crash safety features. We have a carbon fiber safety cage that protects the occupants for less than 10 percent of the weight of a traditional steel chassis in a car.
