The FAA has proposed significant new precautions for air traffic control around California's Long Beach Airport. The agency wants to see Long Beach designated as Class C airspace, which would require more frequent communications by pilots and a higher level of monitoring by controllers. Officials say the changes are necessary because of the high number of collision-avoidance alarms triggered during Long Beach operations. An FAA spokesman says the change is relatively minor. "It's not going to change air routes. It won't ban anyone from airspace, and it will not eliminate flight training areas." But some general aviation pilots contend the Class C designation would lead to new problems without significantly boosting safety.
