Frequently asked questions
Is there customs available at KACK?
No customs office operates onsite at Nantucket Memorial Airport. The nearest customs facility is at KHYA, located approximately 26.87 nautical miles away. Operators arriving from international origins need to plan a stop at KHYA or another designated port of entry before proceeding to Nantucket. This distance should be factored into routing and fuel planning for any international arrival. Dispatchers should confirm current customs procedures directly with the receiving facility, since KACK itself does not provide this service.
What runway options are available at Nantucket Memorial Airport?
Nantucket Memorial Airport has two paved asphalt runways. Runway 06/24 is the longer of the two at 6,303 feet with a width of 150 feet, suitable for larger business jets. Runway 15/33 measures 4,500 feet long and 100 feet wide, offering a crosswind alternative. Both runways are hard-surfaced and support the airport's mix of piston and turbine traffic. The airport is towered, and PAPI lighting on runways 06, 24, and 33 operates continuously.
Are there any taxiway restrictions at KACK?
Yes, Nantucket Memorial Airport has two specific taxiway restrictions. Taxiway F is restricted to small aircraft weighing 12,500 pounds or less. Separately, the section of taxiway F between taxiway B and taxiway H is closed to aircraft with a wingspan greater than 79 feet. Operators of larger business aircraft should review these restrictions carefully when planning ground movements at KACK, since they affect routing options on the airfield.
When is business aviation traffic busiest at KACK?
Business aviation traffic at Nantucket Memorial Airport peaks sharply in summer. July sees the highest monthly volume at 7,588 operations, followed by August at 6,721, according to FAA TFMSC data for 2025. By contrast, winter months such as January and February each record around 500 to 560 operations. This seasonal swing reflects Nantucket's status as a summer destination, and operators should expect denser traffic patterns and ramp congestion at KACK during the peak months.
What wildlife and military traffic hazards should pilots know about at KACK?
Pilots operating at Nantucket Memorial Airport should be aware of deer and birds on and in the vicinity of the airport, which pose a strike hazard during approach and departure. Additionally, high-speed military jet and heavy helicopter traffic operates in the vicinity due to the nearby Air Station Cape Cod. These factors combine to create an environment where extra vigilance is warranted during all phases of flight near KACK. Crews should brief for both wildlife and military traffic before operating in the area.
