GA pilots in Australia are fed up with the way their airspace system is being run, and some of them are planning to demonstrate their viewpoint in a "National Day of Action" on Nov. 27 -- the day new airspace rules take effect. "A handful of union pilots in the airlines, flying less than 200 Australian aircraft, are intent on closing the skies to over 12,000 Australian aircraft owners -- this is unacceptable," said Ron Bertram, president of the Aircraft Owners and Pilots Association of Australia. A Web site, bindook.com, is credited with spreading the plan for the Day of Action, in which GA pilots would refuse to turn on their transponders or communicate with air traffic control while flying in airspace in which positive control is required. Yeeha. The rule changes, which will roll back reforms that opened the airspace to GA aircraft, are "tantamount to being told you can't pull out of your driveway because a bus is expected to pass by in the next few hours," Bertram said.
