Frequently asked questions
Does KGON have customs available on-site?
Groton-New London Airport (KGON) has CBP inspection services available on-site, along with a USDA compliance agreement. This makes it a viable port of entry for arriving international general aviation traffic without a diversion to a separate customs airport. Crews should still coordinate arrival details in advance given standard CBP notification practice for general aviation. The airport is towered, and airport attendance runs daily from 0600 to 1400 local. Fuel after those hours requires advance notice, as noted in airport remarks.
What runways are available at Groton-New London Airport?
Groton-New London Airport (KGON) has two paved runways for fixed-wing operations. Runway 05/23 is 5,000 feet long and 150 feet wide, and Runway 15/33 is 4,000 feet long and 96 feet wide, both with asphalt surfaces. Both runway ends on 05/23 are equipped with an Engineered Materials Arresting System (EMAS), 130 feet by 162 feet at the Runway 05 departure end and 340 feet by 162 feet at the Runway 23 departure end. A third listed surface, H1, measures only 45 by 45 feet and serves helicopter operations rather than fixed-wing traffic.
Are there any operating restrictions on jet traffic at KGON?
Yes. At Groton-New London Airport (KGON), practice approaches, full-stop landings, and touch-and-go landings are prohibited for pure jet aircraft and for any aircraft weighing 12,500 pounds or more, except with written approval from the Connecticut Airport Authority. Separately, no touch-and-go operations of any kind are permitted between 2200 and 0600 local. Noise abatement procedures also apply on departure from each runway, involving specific turn headings maintained until reaching 1,000 feet before resuming course. Operators planning training or pattern work at KGON should account for these restrictions ahead of arrival.
What is the pavement strength rating for the main runway at KGON?
The pavement at Groton-New London Airport (KGON) carries a PCR value of 1750/F / A/X / T, as published in the airport's pavement classification data. This rating is used by operators and dispatchers to assess whether a given aircraft's gear configuration and weight are compatible with the runway pavement. The airport's primary runway, 05/23, is 5,000 feet long and 150 feet wide with an asphalt surface. Crews operating heavier business aircraft into KGON should cross-check this PCR figure against their aircraft's ACN before planning a landing.

Business aviation traffic at Groton-New London Airport (KGON) concentrates heavily in the summer months. July, August, and September each recorded well over 500 operations in 2025, with August peaking at 618, compared to figures in the low 200s during winter months, according to FAA TFMSC data. Total annual operations for 2025 reached 6,098, with business aviation accounting for 3,950 of those movements.
