Wild Blue Wonders: Light Flight's Spark in Young Readers

NASA has a history of reaching out to young people. It’s a part of their charter. That’s one of the reasons the agency wanted to produce an informational book about aviation for middle school-aged kids, what it perceives as an underserved demographic.

To that end, the nation’s space agency joined forces with EAA and approached Flying Magazine West Coast Editor Lane Wallace (one of the best in the business) to write the book. The result, Wild Blue Wonders: Exploring the Magic of Flight, has been a steady seller since it first became available at AirVenture Oshkosh 2001 in July, and is currently available on-line through the EAA Web Store or at the AirVenture Museum store Aeronautica.

Shuttle Launch
Reset for Dec. 4; New NOTAMs Issued
Shuttle managers have targeted Tuesday, Dec. 4, for the next launch attempt of the Shuttle Endeavour. The FAA has issued new NOTAMs (FDC 1/2844 and 1/2845)effective immediately until further notice, to protect the airspace surrounding the Kennedy Space Center and Cape Canaveral. As always, pilots are urged call Flight Service for the latest information before taking off.

There’s much to like about Memphis Class B NPRM ... but there's room for improvement as well
EAA’s preliminary review of the Memphis Class B airspace Notice of Proposed Rulemaking (NPRM) shows it is generally friendly towards general aviation. With a little tweaking by the FAA however, it could be even more accommodating to GA.
FAA Order 7400.2D sets the basic design of Class B airspace as a circular configuration centered on the primary airport with circular rings set at 10, 20, and 30 nm - all designed to protect the published instrument procedures of the primary airport. This is exactly the design of the Memphis Class B airspace, except for ease of IFR navigation, the FAA modified the rings to be centered on the Memphis VORTAC - and EAA applauds the FAA for this design change.

EAA Urges Members to Support GA Relief Legislation Bill
Bill Provides up to $7.5 Billion in Loans and Grants For GA Businesses
On Tuesday, Nov. 27, Congressman John Mica (R-Fla.) introduced the “General Aviation Industry Reparations Act of 2001,” (HR 3347) and EAA is urging members to contact their congressional representatives and ask them to co-sponsor this vital legislation. This is the long-awaited relief package to help GA businesses that incurred—and continue to incur—severe economic losses due to the airspace closure and lingering restrictions related to the Sept. 11 terrorist attacks.

An Update for Sport Pilot Enthusiasts
In recent weeks EAA has been receiving an increasing number of telephone and e-mail inquiries wondering about the status of the sport pilot/light-sport aircraft proposal. Obviously, the events of September 11 have changed the priorities of many facets of our society. Realistically, the DOT, FAA, and others have rightly focused their attention on returning U.S. airspace to near normal operations and making air travel safer. EAA applauds those efforts and has been an active participant in those discussions. At the same time, DOT and FAA have given no indication that their support of the sport pilot/light-sport aircraft proposal has wavered.

The Meigs Field Roller Coaster Continues
The Friends of Meigs Field in Chicago reported in a Friday news alert that on Thursday, Nov. 29, the beleaguered lakefront airport went from a "permanent" assured life of 25 or more years to being the scapegoat for a possible failed O'Hare deal. In short, nothing is settled yet as negotiations continue between Chicago Mayor Richard Daley and Illinois Governor George Ryan. A key point of debate was apparently the refusal of the state to commit to a $4 million annual funding plan to cover the annual Meigs deficit. However, the most recent financial figures available to the FOM (1998) indicate that the annual Meigs deficit is less than $150,000 on an operating budget of less than $1 million. For more information, visit the FOM website at www.friendsofmeigs.org.

EAA, Centennial of Flight Commission Form Alliance

EAA and the U.S. Centennial of Flight Commission (COFC) have signed an agreement to jointly publicize the celebration of the 100th anniversary of the Wright brothers' first powered flight in 2003. COFC will provide national outreach support for EAA's Countdown to Kitty Hawk initiative, and EAA will help promote the commission's national celebration called "Centennial of Flight: Born of Dreams. Inspired by Freedom."
"The Wright Brothers represent innovation, dedication, and a sense of adventure -- the same qualities that lie at the heart of EAA and its members," said EAA President Tom Poberezny, who is also an appointed COFC member. "We look forward to bringing that historic moment back to life on Dec. 17, 2003, from the sands of Kitty Hawk."

Flyin’ Tiger’s Record Flight at Sun ’n Fun Confirmed
The Federation Aeronautique has finally confirmed Bruce Bohannon and the Exxon Flyin’ Tiger as the new world record holder for “Altitude in Horizontal Flight, Class C-1.b: 35,497 feet. The previous record - 33,732 feet – was set in 1984 by West German Richard Floh in a turbocharged Mooney. “This one’s special,” says Bohannon, “because it’s a win for us and a win for our country.” Team Tiger was confident they had broken the record as pilot Bruce Bohannon completed the mission at Sun n’ Fun 2001 in Lakeland, Florida last June.
Bohannon had to not only reach his target altitude, but also hold it for 90 seconds without losing airspeed or altitude. The Tiger’s Mattituck Red/Gold engine never missed a beat, churning out the horsepower without the aid of turbos or nitrous oxide. Team Tiger now has its sites set breaking the absolute altitude record for class C-1.b, which now stands at 36,188 feet. To set a new world record, Bohannon will have to beat that by at least 3 percent, or 37,274 feet, but the goal is 40,000 feet.

Q & A:
Question of the Week
Question For EAA Aviation Information Services -  I'm in a Part 141 ground school, and in studying aircraft instruments and their purposes, I'm confused by the operation of the "manifold pressure" gauge. In a normally-aspirated four-stroke engine, isn't the intake manifold under a partial vacuum when the engine is running? What is the source of the pressure being measured?

Answer: You're correct in your understanding of the workings of the engine. The manifold pressure gage displays, in inches of mercury, the atmospheric pressure inside the intake manifold. Depending on engine design, this pressure can be above or below ambient atmospheric pressure when the engine is running. You'll notice that the manifold pressure gage reads ambient atmospheric pressure (around 30 inches of mercury) when the engine is stopped. When it's running, the "pressure" in the manifold of a normally aspirated engine is less than ambient pressure, and varies depending on throttle position. This is in fact a partial vacuum, as you've stated. Some engines are "supercharged" by either an exhaust-driven turbocharger or a mechanically driven supercharger. These engines are capable of producing manifold pressures in excess of ambient atmospheric pressure, which gives them the ability to produce rated power at higher altitudes.
