Boston Logan Airspace Map

Protecting Boston Logan’s Airspace

Massport has a Composite of Critical Airspace Surfaces Map (the Critical Airspace Map) which defines the critical airspace around Boston Logan International Airport (Logan Airport). The Critical Airspace Map was created to protect Logan Airport’s flight corridors and inform developers on building height limits around Logan Airport.  Failure to protect Logan’s airspace will result in a reduction in safety, loss of airport efficiency, and impact runway utilization potentially shifting flights from one community to another.

Height limits captured by the Critical Airspace Map incorporate the highest points of a structure including roof-top mechanical and HVAC units, signs, antennae, lighting, solar panels, etc. Massport requires developers coordinate with Massport for specific analysis of projects before filing the FAA Form 7460-1.

Developers are also asked to review the use of construction cranes with Massport which will also need to be filed separately with the FAA Form 7460-1.  Cranes are considered temporary but it is important that developers work with Massport and the FAA to minimize the extent and duration of the impact on Logan’s airspace.

Once a project is complete, developers must file with the FAA Form 7460-2 which is based on as-built survey with 1A accuracy.  The 7460-2 confirms the final height of the building/project to Massport and the FAA for incorporation into the FAA’s national airspace database.

Installing solar arrays

If solar panels are being planned, the proponent must contact Massport at Depending on the location and type of installation, the proponent may need to undertake a solar glare study pursuant to FAA guidance.

Aircraft Noise

Projects directly under flight paths and closer to the airport may also be impacted by overflight noise.  Boston Logan operates 24 hours per day and 365 days a year.  Flight paths are primarily determined by wind and weather and the FAA’s selection of specific runways.
