Aviat Aircraft’s Stu Horn brought an aircraft to AirVenture 2013 that burns traditional aviation fuel (100LL) and can also fly on compressed natural gas. Horn says the first 20 hours of flight testing have started to show that natural gas burns cleaner in the engine, offers more power, and is arguably safer to store than traditional liquid fuels. Horn believes the lower cost of natural gas could become a compelling argument for flight schools and budget-conscious aviators. He also believes that technological advances will quickly result in lighter storage tanks, making the fuel an even more efficient option.
