The partners agreed that any biofuel program had to meet three criteria:
The two hour test flight reached a height of 35,000 feet and included several specific tests of the fuel at different altitudes. The test elements included a full thrust take off, a variety of climb power settings, engine acceleration tests, and in flight and ground shut down and restarting. The engine using the biofuel will be examined in detail and compared to the engines using petroleum-based fuel. The goal of the test was to confirm the new fuel’s specific gravity, efficiency, and economic value. Specific numbers and results have not been released at this time.
