It is a fairly inexpensive place to rent airplanes, as the starting rate is $75/hour for a two-seater Cessna 150. The airport has lots of parking spaces out in the sun or in hangars. The Sterling Airport closes its runways in October when the Sterling Fair is up and running at the airport, during which time, all the aircraft tied down on the field must be flown elsewhere. Even the glider trailers are moved off-field. But after the fair, the airport opens for normal operations once again.
Sterling Airport is also the home of the Greater Boston Soaring Club.
Sterling Airport covers an area of 100 acres (40 ha) at an elevation of 459 feet (140 m) above mean sea level. It has one runway designated 16/34 with an asphalt surface measuring 3,086 by 40 feet (941 x 12 m) and one helipad designated H1 which is 50 by 50 feet (15 x 15 m).
