In 2014, the Neighborhood of Affordable Housing’s Environmental Youth Crew conducted a study on sleep interruptions after the FAA canceled ‘Head to Head’ operations at Logan. At Logan Head to Head operations were a noise abetment procedure that Massport and the Community Advisory Committee (CAC) worked on and the FAA agreed to over a decade ago. The study found reported sleep interruption of 36 percent in central Chelsea–also directly under the flight path but further away– and 24 percent, 22 percent and 18 percent respectively, in central Eagle Hill, Orient Heights and Maverick study areas adjacent to the flight path.
