Airport, Prodded by FAA, Bars Liftoffs Toward East

Times Staff Writer

At the insistence of the Federal Aviation Administration, Burbank Airport authorities Wednesday barred airline pilots from taking off toward the east, a policy an airport spokesman warned will sometimes force airlines to remove passengers from departing jetliners.

Under Santa Ana wind conditions, if some runways cannot be used, jetliners loaded with fuel for long flights may be too heavy to take off on the remaining available runways, which slope uphill, and so will have to lighten their loads by reducing the number of passengers, airport spokesman Victor Gill said.

Even with the eastbound takeoff option still available Tuesday, American Airlines had to cancel the reservations of 30 passengers on a 145-seat jetliner bound for Chicago, Gill said, because of wind conditions. With easterly takeoffs banned, the problem will grow worse, he forecast.

Location the Problem

The problem has its roots in the location of the 55-year-old airport terminal. It is only 313 feet from a runway at some points, less than half the safety zone of 750 feet required by modern safety regulations. The FAA has been waiting several years for the Burbank-Glendale-Pasadena Airport Authority to replace it.

After the airport authority's plans for a new terminal collapsed in December, however, the federal agency began insisting on immediate changes in the airport layout and procedures until a new terminal is built. It is expected to be several years before one is ready.

The president of the airport authority, Robert W. Garcin, has warned that the financial burden of meeting the FAA's demands and adverse court rulings on noise-nuisance lawsuits may push the airport to extinction.

A private meeting held at the airport Wednesday was attended by three members of the airport authority, five FAA officials and all four people on a committee representing airlines that fly out of the airport.

At the meeting, the FAA officials demanded an immediate ban on eastbound takeoffs, Gill said.

The ban went into effect at 4 p.m. Wednesday afternoon, within minutes of the end of the meeting.

The rule will not please anti-noise protesters. San Fernando Valley homeowner groups and the City of Los Angeles have been trying to encourage takeoffs toward the east to reduce jetliner noise over the Valley by routing more flights over Glendale and Pasadena.

Ban Requested Previously

The FAA first requested such a ban in February, on the basis that planes taking off toward the east come too close to the terminal and reach takeoff speed just as they pass an area where parked jetliners load and unload passengers between the runway and the building.

The authority contended that, in the past, the FAA took sole charge of such aircraft traffic rules, limiting airport operators' authority to ground facilities.

On March 13, the manager of the airports division of the FAA's western regional office, Herman C. Bliss, wrote to the authority, again asking it to enact such a rule, and demanding that the authority come up with specific plans within 30 days to implement other requested changes.

Those include converting 1,457 auto parking spaces into aircraft parking space to move jetliners farther from the runways. The parking spaces generated $1.7 million in fees last year, one of the chief financial supports for the airfield.

As far as the airport authority is concerned, Gill said, it is not acting on its own in forbidding takeoffs to the east, but is enforcing an FAA request "pending forthcoming rule making by the FAA on this subject."

The rule applies to all multi-engine planes weighing more than 12,500 pounds, a category that covers all commercial airliners and some private business jets. It is expected to remain in force until the existing terminal is razed. No site has yet been chosen for a new building.

The ban will cause problems for some flights during periods of Santa Ana winds, Gill said, forcing airlines to remove passengers from flights or to forbid them to board.

The airport has two runways. One runs roughly from north to south; the southern end is slightly lower. The other, which is 828 feet shorter, runs east and west, and the eastern end is lower.

Normally, the wind blows from the west or southwest. Pilots try to take off into the wind, or with the wind from the side, to increase the lift on the wings. A wind from the rear decreases lift.

Consequently, airline pilots--who make the final decision--take off from north to south about 90% of the time at Burbank, preferring the longer runway with the downhill slope, running into the wind or at right angles to it.

However, Gill pointed out, Santa Ana winds, blowing down from the north, make that choice undesirable. The usual alternative is to take off toward the east. Although that runway is shorter, the pilot could utilize the downhill slope to reach takeoff speed.

Since the FAA has prohibited that alternative, pilots will be required during Santa Ana conditions either to take off toward the north or the west, he said.

In both cases, the runway slopes uphill.

At times, the only way to take off safely will be to lighten the plane, and that means eliminating passengers, he said.

The problem is expected to be especially severe for large aircraft loaded with fuel for long flights, Gill said. Although commuter flights to California cities dominate traffic at Burbank, there also are many flights to cities east of the Rockies.

The U.S. Weather Service said statistics are not available on how many days a year Santa Ana winds blow. In the past, Gill said, airline pilots have chosen to take off toward the east, because of Santa Anas or other reasons, about 5% of the time.

Talks will continue on the other changes the FAA requested, Gill said.

"The airlines expressed unhappiness at all of their options," he said, adding: "They don't want to lose parking spaces for their aircraft; they don't want their customers to lose convenient places to park their cars at this airport, and they don't want to pay the money that would be necessary to replace the revenues from the lost parking spaces." BURBANK RUNWAYS In normal wind, most airliners take off from north to south--downhill and into the wind for maximum lift. Santa Ana winds reverse the possible directions, with pilots preferring west-to-east takeoffs, downhill and with the wind from the side. With takeoffs to the east now banned because of the proximity of the terminal to the runway, Santa Anas will mean mostly south-to-north takeoffs--uphill. As a result, some planes may have to be lightened on short notice by reducing the number of passengers.
