No “Magic Bullet” to Replace 100LL
After 19 years of work to find a lead-free substi- tute for 100 low-lead aviation fuel (100LL), there is no solution that offers a seamless transition
from leaded to unleaded fuel for high-performance aircraft engines.
AirVenture’s Aviation Learning Center, supported by
Chevron Global, hosted a panel of representatives from
the Environmental Protection Agency, FAA, GAMA, Coordinating Research Council, and FAA Technical Center
who collectively have conducted or coordinated much of
the fuel research to date.
“We are no longer seeking a ‘transparent’ or ‘drop-in’
replacement for 100LL—one that wouldn’t require modifications to the aircraft or FAA approval for each aircraft,”
said Walt Desrosier, a vice president of GAMA.
Alternatives under study include low- or medium-oc-
tane unleaded avgas, high-octane synthetic fuels (mainly
biofuels), and new blended fuels. The solution has to be a
worldwide standard, panel members agreed, and it has to
be a long-term solution.
High-performance aircraft engines—powering about 30
percent of the U.S. general aviation fleet—are designed to
use leaded fuel to control engine detonation.
Any potential alternative to 100LL will require extensive testing to determine its effects on the engine and fuel
system, aircraft systems and performance, as well as engine cooling and weight. In addition, researchers will have
to identify certification issues and the costs of the fuel, as
well as needed aircraft modifications.
States will need to meet the new lead air quality standard by 2016 or 2017, and aviation gasoline may need to
be part of the solution.
Gathering of Eagles
This year’s Gathering of Eagles gala during AirVenture proved once again the aviation community is stead- fast in its support of aviation’s future. More than
1, 100 people attended and raised $1.97 million, which will
help support programs and experiences that inspire and
motivate kids to pursue their aviation dreams.
The donations will help build the Young Eagles First
Flight and Next Step programs that engage kids in aviation-related activities.
The event’s signature item—the AirVenture Xperimental
2010 Mustang (AV-X10) Dearborn Doll built exclusively for
the event by Ford Motor Company—brought the night’s
highest single bid of $250,000.
The Windsock Challenge totaled $300,000, silent auction items raised $100,000, and the Sean Tucker Experience, which includes lunch with Bob Hoover and Harrison
Ford, sold for $50,000.
Jeff Skiles offered the flight jacket and shoes he wore
the day he and Chesley “Sully” Sullenberger were forced to
ditch Flight 1549 into the Hudson River in January 2009.
Those items alone brought in $38,000, an amount that was
doubled by Airbus.
WomenVenture a Success
Hundreds of women gathered on AeroShell Square July 31 to celebrate women’s success in aviation and to encourage other women to follow their
dreams of flight.
The second annual WomenVenture day at AirVenture
brought an estimated 600 women to AeroShell Square
for the photo, including Women Airforce Service Pilots;
air show performers Debby Rihn-Harvey, Julie Clark,
and Jill Long; the Misty Blues; and others.
Peggy Chabrian, president of Women in Aviation
International, said there are two reasons events like
WomenVenture are important. “It’s the camaraderie,
meeting other women pilots and interacting,” she said.
“But as these women are walking around wearing their
WomenVenture T-shirts, hopefully other women and
children will talk to them about flying. Hopefully this
event will spark interest in aviation for women. It tells
them it’s okay to be involved.”
