Flight Tests Scheduled For Tuesday

WILMINGTON, OH - July 1, 2004 -- On Tuesday, July 6, 2004, people in the vicinity of the Wilmington airport may see a DC-9 aircraft flying lower and at higher speeds than normal. This is a specific requirement for a test flight being conducted by ABX Air, Inc., to verify the accuracy of newly installed aircraft equipment.

The series of flight tests will involve multiple passes back and forth over the airport as low as 400 feet off either end of the runway and at speeds between 220 and 415 miles per hour. These passes will extend as far as 10 miles from the airport along the centerlines of the runways.

The flight test will be accomplished by an ABX Flight Crew and Flight Test Engineers from ABX Air and Aeromech Inc. of Seattle, Wash., and should lead to FAA approval of the aircraft to fly in more compacted airspace in the near future.

Residents also might see a small drogue cone being towed about 150 feet behind the tail of the aircraft. The cone is tethered to the aircraft, and its purpose is to gather static air pressure data during the test flight.

If bad weather should prevent the test flights on Tuesday, they may occur on Wednesday, July 7.

The FAA has approved the planned test flights, and the flight crew will be coordinating closely with air traffic control facilities at Wilmington and Dayton.
