Class D Airspace Shrinks to 4.2 Miles
The FAA proposes to reduce the Groton-New London Airport Class D airspace from a 5-mile radius to a 4.2-mile radius, still excluding the 1-mile radius around Elizabeth Field. The Class D area would extend from the surface up to 2,500 feet MSL and the effective dates/times will be published in the Chart Supplement.
FAA Expects De Minimis Costs to Operators
The FAA says this proposed change is routine and is expected to cause, at most, de minimis costs from compliance or minor flight rerouting. The agency certified the proposal will not have a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act.
