The New York Times reports that Park Slope residents complain about aircraft noise:

EVERYONE agrees that Park Slope is no Flushing or Howard Beach, not one of those neighborhoods where the whine of descending jets is as familiar as birdsong. But ever since 2000, its residents have complained of an increase in noise from low-flying jets bound for La Guardia Airport.
The battle has been fought on many fronts. A neighborhood group, the Park Slope Quality of Life Committee, posts pictures of low-flying planes on its Web site, along with a petition asking the Federal Aviation Administration to limit air traffic to La Guardia and vary the approaching flight patterns.

Good grief. Suffice to say I am not sympathetic to the stroller-set’s complaints.
Normal arrivals to LGA take one of three vectors:

1. The Runway 22 approach which aircraft generally proceed up the west side of Manhattan for a series of right-hand turns over the Bronx to land north-to-south.
2. The Runway 4 which takes aircraft over Brooklyn (Park Slope and my home of Greenpoint) landing south-to-north.
3. The Runway 13 approach is used when the wind shifts and vectors aircraft over the northern tip of Manhattan to land west-to-east.¹

All of this illustrates how immensely crowded New York Airspace has become, with arriving and departing aircraft from La Guardia, Kennedy, and Newark and from numerous regional airports throughout the region. You just can’t up and change approach vectors due to the stroller-set noise complaints. In fact the FAA is attempting to redesign the regional airspace, which you can read about here: New York/New Jersey/Philadelphia Airspace Redesign.
But what of aircraft noise? On approach to Runway 4, aircraft descend from 2700 ft to 1700 ft over Park Slope – which is higher than the Empire State Building. La Guardia handles regional traffic (flights less than 1,500 miles)² with airlines generally using smaller Regional Jets or MD-80’s.
If the Park Slope Quality of Life Committee really wants to reduce aircraft noise, petitioning the FAA is a non-starter, and they should put their energy into supporting regional high speed rail initiatives which will take more planes out of the sky. Initiatives such as California’s High Speed Rail creating regional high speed rail is exactly the correct policy which will reduce aircraft flying over their delicate heads.
Or, they can get over themselves. You live in New York City. It is loud here and aircraft noise should be the least of your noise complaints.

1. Incidentally, out of all the trips in and out of LGA, I’ve only actually landed this way once. ↩
2. Due to the Port Authority banning flights longer than 1,500 miles in order to shift transatlantic and transamerican flights ↩
