Largely free from FAA certification rules, the experimental and light-sport aircraft markets are home to big ideas at low prices. Builders and owners equipping with non-certified avionics can have all the features of the most modern business jet or airliner-at a fraction of the cost. While many of the technologies ultimately fail or stay experimental, others are picked up by established avionics companies to be incorporated into new or upgraded products for the certified market. The annual week-long Experimental Aircraft Association's Air Venture general aviation show in July is often the site of the "pickups." At this year's show, Aviation Week focused on five small companies-Levil Technology, Vertical Power, DepotStar, World Aircraft Co. and Aerocross-that are developing innovative products for the experimental and light-sport aircraft market, often with a longer-term goal of reaching into the certified market.
