That knocking you hear in a piston engine is caused by detonation. Also called spark knock, detonation results when the air/fuel mixture explodes everywhere at once prior to spark ignition. When the fuel air/mixture is compressed, its temperature increases even as residual heat from the previous cycle is absorbed into the cooler mixture. If the fuel's flame point is exceeded, the mixture can explode all at once without waiting for a spark. The combustion pressure wave that meets the ascending piston is heard as a knock.
The association of Independent Contract Aviation Professionals (ICAP) is being formed to support independent contract pilots, flight attendants and maintenance technicians.

There's a new sheriff in town. John E. Thompson is resigning as chief pilot at Byerley Aviation in Peoria, Ill., to serve a four-year term as the newly elected sheriff of Bureau County, Ill. Bureau County lies due north of Peoria; so give a wag of your wings to John as you pass between Princeton and Spring Valley, Ill., on descent into PIA.
Everywhere I go, people say, `I know Showalter,''' says Jenny Showalter, a third-generation member of the family whose Florida FBO, Showalter Flying Service, is known far beyond its leasehold at Orlando Executive Airport.
A shortage of propylene glycol, the key ingredient of de-ice fluid, may make that often-vital substance scarce, or substantially more costly, this winter -- possibly both. Propylene glycol is brewed from isopropyl alcohol and glycerin, which are in turn processed from vegetable matter. While Dow Chemical's two processing plants at Freeport and Plaquemine in the Bahamas were shut down for scheduled maintenance, tropical storms damaged the source crops and the processing facilities could not be restarted before that vegetable material became unusable.
Air Nostrum of Spain won the gold medal and title of ``Airline of the Year'' at this year's European Regions Airline (ERA) Association General Assembly in Salzburg, Austria. Silver and bronze winners were the same as in 2001 with Norway's Wilderoe taking second place and Air Dolomiti of Italy in third. The winners were selected by an international panel of journalists who judged 15 submitted entries. The winning criteria included profitability, traffic growth and innovation.
Engine issues are slowing Eclipse 500 flight testing, though the program is advancing on other fronts. After the twinjet's first flight in August, the only two EJ-22 engines were removed from the aircraft and shipped to the manufacturer, Williams Research. Eclipse officials stated that the engines need to produce more thrust and that there are challenges fitting all the engine accessories into the available engine space. At press time, Eclipse did not have a projected date for when the 500 will fly again.
Hunt and Palmer and Air Partner, both British air charter operators, have announced significant increases in their businesses over the past 12 months.

Honeywell Primus Epic integrated avionics have been chosen to equip the PlaneView cockpit in the Gulfstream G500 and its SPZ-8400 avionics for the G300. The two aircraft are part of the expanded and renamed Gulfstream line of aircraft. The G500 is a 5,800-nm version of the GV-SP that is designed to compete against the Falcon 7X and Bombardier Global 5000. The GV-SP, newly designated the G550, also incorporates the PlaneView avionics. The G300 is a variant of the GIV-SP with less fuel capacity and range. The G400 is the equivalent of a fully loaded GIV-SP.

(Kelly) Ortberg has been appointed as vice president and general manager of air transport systems for the company's commercial systems business.
FAA officials plan to form an advisory committee, similar to the ETOPS ARAC (see above), to support its efforts to review and revise FAR Parts 135 and 125 (see Intelligence, November, page 17). Officials expect shortly to release the charter that will outline plans for the task. Kathy Perfetti, manager of the FAA's newly established Part 135 and Fractional Ownership Operations Branch, has been working with industry and already has received a number of expressions of interest from potential participants. The FAA wants to keep the committee relatively small in number.
As part of its continuing effort to trim costs, Bombardier Aircraft has eliminated several management positions, including two key posts and familiar names associated with product development. Peter Reynolds, vice president of the company's Wichita flight-test center, and John Taylor, vice president of product development in Montreal, were among those let go in late October. Reynolds is a well-known flight test pilot and received numerous industry awards during his three decades at Learjet and Bombardier. F.G.
The FAA is offering bird-strike data online in the hope of promoting more reporting, an FAA official told The Weekly of Business Aviation. Identification and tracking data of bird species involved in collisions with aircraft are compiled by the FAA and its partner, the Smithsonian Institution's Feather Identification Lab, which has more than 620,000 bird species in its 150-year-old collection. After bird strikes occur, airport operators send the remains -- which are often feathers -- to the lab for identification.
GAMA reports the 1,766 new aircraft units shipped worldwide in the first nine months of this year represented a decline of 16.6 percent over the same period in 2001. Of the total, 497 were business jets (down 12 percent), 170 were turboprops (down 40 percent) and 1,099 were piston-powered (down 13.4 percent). The combined value of the new aircraft was put at $8.4 billion.
A new regional airport, Niederrhein, 80 km north of Dusseldorf, Germany, on the Dutch border, is due to open to the airlines in February 2003. A 136,000-square-foot passenger terminal is being constructed to handle up to 1.5 million passengers per year. The airport's management hopes to attract scheduled airlines, low-fare carriers, and leisure and freight operators. Around $25 million has been spent on the project so far by its 99-percent-owned Dutch investment group. M.V.
FAA Administrator Marion C. Blakey has addressed a series of forums within the aviation community since her appointment. Speaking before the AOPA Expo in Palm Springs, Calif., Blakey acknowledged that the FAA's role is to be ``an advocate for commerce and the economic benefits of aviation'' and said, ``We will never overlook an opportunity to remind our colleagues in the security agencies of the importance of general aviation.'' But she added that the community must be its own best advocate before the Transportation Security Administration.

For all of us in the northern climes, the winter solstice is soon to be upon us, and for many, the season's ice and snow have already arrived. The flexibility of business helicopters in shuttling between airports, corporate headquarters , city heliports and off-field landing sites can really come to the fore when ground traffic snarls in frigid weather. But the months to come will also present special obstacles to rotary operations.
