In a bid to cut traffic at Teterboro Airport, N.J., airport operator The Port Authority of New York and New Jersey is proposing a four-pronged assault that would ban Stage 2 aircraft, ban the Federal Reserve from flying checks at night, ban aircraft with an mtow of more than 80,000 pounds (20,000 less than the current limit) and raise landing fees. The move comes hot on the heels of victory in the U.S. Court of Appeals by the Naples (Fla.) Airport Authority, upholding its ban on Stage 2 jets. A weight limit of 80,000 pounds at TEB would prevent Global Express and Gulfstream V/G550 operations at the busy airport not far from New York City. The FAA is expected to challenge one or more of these proposals, but PANY&NJ chairman William Coscia has said the Port Authority is prepared to take legal action if necessary to ban Stage 2 jets at Teterboro. Meanwhile, a study under way by the Los Angeles World Airport Authority (LAWA) does not yet contain an outright ban on Stage 2 aircraft at Los Angeles International and Van Nuys Airports as one of the implicit goals, but city officials have made it clear they are taking a close look at the Naples Airport case.
