Thousands of area residents, overwhelmingly opposed to the controversial test of the aircraft scatter plan for takeoffs from National Airport, continued yesterday to jam the switchboards of the Federal Aviation Administration, local governments and legislators to protest the plan.

FAA spokesman David Hess said that as of 1 p.m. yesterday the agency had received 1,099 calls against the plan and 227 for it since the test -- aimed at a more equitable distribution of aircraft noise around the area -- started on Monday.

Hess said the FAA's telephone comment line (557-2081) had been jammed with calls and that extra lines were to be set up last night.

Unlike in Virginia, local governments and members of Congress in Maryland and the District of Columbia reported getting only a few calls, most of them complaints.

In Arlington County, where the County Board and county manager's offices have received more than 110 calls opposing the plan and none in favor, board clerk Jean Julian said, "There's never been a response like this. We've had just three people constantly answering the phones."

Alexandria's citizens assistance office reported receiving about a dozen calls against the plan, many of them from Arlington residents. In Fairfax County, Board of Supervisors Chairman Jack Herrity plans to ask the board on Monday to establish a formal system to monitor opinion on the test, a spokeswoman said.

A spokesman for Rep. Frank R. Wolf (R-Va.), whose 10th District includes the airport and many residents affected by the plan, said his office had received 125 calls against the plan and one in favor. Rep. Stanford E. Parris (R-Va.) has received about 20 calls, most in opposition, a spokeswoman said.

Sen. John W. Warner (R-Va.) has received about 100 calls, mostly from opponents of the plan, a spokesman said. Virginia's other senator, Republican Paul S. Trible, has been averaging about 60 calls a day from opponents, with no calls from plan supporters, a spokeswoman said.

The Metropolitan Washington Council of Governments, which requested the scatter-plan test, has received only a handful of calls, a spokesman said.
