Depending on the weather, Belmont, Watertown and Brighton may experience a greater frequency of audible overflights from Logan in late May and June.
Massport will be doing necessary safety maintenance on some of its runways during the coming construction season, as explained in this press release.
Dave Carlon, the Chair of the Massport Citizens Advisory Committee passed on this additional information about the impact on individual communities.
The closure of Runway 4R/22L, from May 15, 2017 to late June, and follow on daily work is to accommodate the R4R/22L safety rehabilitation project and may result in changes in runway use. Certain communities may experience changes in overflights. The primary driver of runway use will still be wind and weather. When winds are strong from the Northeast, the FAA has approved for use an RNAV to R4L (this will provide positive guidance to the aircraft, recall R4L is a VFR runway with no positive procedural guidance today) and an RNAV to R4R side-step to R4L. When winds are from the Southwest, the runways available will be R22R for departures (and some arrivals) and R27 for arrivals. When winds are light from the Northwest runways available will be R33L, R33R, R27 while if winds are strong from the Northwest R32 will also be available. When winds are from the Southeast R15R and 9 will be available. The longest runway available for will be R15R/33L. Subject to wind and weather and air carrier preferences, R15R/33L runway (along with R9/27) may see increase in use during more marginal wind conditions when the FAA tower may have more flexibility to utilize this configuration. Finally, the only CAT II/III runway (lowest visibility conditions) available will be R33L from May 15th to the beginning of September. After the initial closure period through late June, it is anticipated R4R/22L will be available for use during the busiest afternoon/evening period (about 2PM to 10PM).
Runway 33L is the runway that generates overflights in Belmont, Watertown and Brighton. To the extent that the weather favors 33L while the runways 4R and 22L are closed, we will experience more noise.
Long term efforts continue to develop strategies for abating this noise as explained in other posts in this thread.
