live map →12 overflights/day (88%) · typically 2,800 ft
Marsfield lies near the 16R arrival corridor's outer reaches, with south-flow arrivals descending overhead at low-to-moderate altitude. The stream runs in multi-day south-flow stretches and largely disappears in north-flow, so quiet and busy periods alternate with the weather.
Helicopters & other light aircraft
2 overflights/day (12%) · typically 2,600 ft
Around 2 low overflights a day come from aircraft not operating at a tracked airport — helicopters, seaplanes and light aircraft transiting the area. Light-aircraft counts are tracked overflights only — many training and private aircraft carry no ADS-B transponder, so true numbers are higher.
