We usually think of airplane flight performance in terms of gallons an hour – not miles per gallon.
But on a recent transcontinental flight in a fairly typical single-engine, four-seat, 180-horsepower general aviation aircraft, I was astonished at my poor mileage. Despite a light load, conservative power setting, high altitude, leaned aggressively, and a tailwind, I was getting a Hummer-like 17 miles per gallon.
By chance, I stopped at Santa Paula Airport (SZP) in Southern California for fuel and an overnight stay. SZP is the home of aeronautical innovator Klaus Savier, AOPA 1252301, and his company, Light Speed Engineering (www.lightspeedengineering.com). Savier has been setting speed and efficiency records for two decades in his experimental, Rutan-designed Vari-EZ – an airplane that serves as a technology demonstrator for products that hint at possibilities for improving the efficiency of the GA fleet.
Savier’s personal airplane gets 50 miles per gallon at 190 ktas, and close to 100 mpg at max range. Sure, it’s a one-of-a-kind creation. But Savier says the GA fleet could get an immediate 20 percent efficiency increase by switching to electronic fuel injection and ignition systems. Will the GA industry ever see the kinds of radical improvements in efficiency and reliability that have come to other forms of transportation? Share your thoughts here.
