 On November 16, 2009, the FAA announced that the new rules for the Hudson River corridor would go into effect on November 19, 2009, at 4 p.m. The FAA elaborated on the new rules from their previous announcement. In the clarifications, they said that three air traffic zones for different purposes would be instituted. Under 1,000 feet (300 m), planes and helicopters for sightseeing and lingering would be allowed. From 1,000 to 1,300 feet (300 to 400 m), aircraft would be allowed to fly without air traffic control handling. Above 1,300 feet (400 m), aircraft would be allowed to traverse the corridor under the handling of air traffic control.
