Frequently asked questions
What is the runway length at KASH?
Boire Field, identified as KASH, has a single runway, 14/32, measuring 6,000 feet long and 100 feet wide with an asphalt surface. That length supports most business jet types operating into Nashua without payload restrictions tied to runway distance. The field elevation is 200 feet. The airport is towered, and lighting for the runway includes MALSR, REIL, PAPI, and HIRL systems that activate on CTAF when the tower is closed. Pilots should plan around a 44:1 approach slope to the displaced threshold on the runway noted in airport remarks.
Does KASH have on-field customs clearance?
Boire Field does not have onsite customs clearance for international arrivals. The nearest customs facility is at KMHT, Manchester-Boston Regional, located 9.67 nautical miles away. Crews arriving from abroad need to coordinate clearance through that airport rather than Nashua directly. This distance is short enough that many operators treat it as a quick repositioning leg rather than a major routing detour. Dispatchers should confirm current customs procedures and hours directly with KMHT before planning an international arrival into the Nashua area.
What are the wingspan restrictions on the ramp at KASH?
Boire Field restricts a specific ramp area to smaller aircraft: the ramp between Taxiway D and Taxiway E is closed to aircraft with a wingspan greater than 48 feet unless authorized by the airport traffic control tower. Operators of larger business jets planning to use that ramp area should contact the tower in advance for authorization. This restriction applies specifically to that taxiway segment and does not affect the runway itself, which is 6,000 feet long. Crews flying wide-span aircraft into KASH should factor this into ground handling and parking planning.
When is Boire Field attended and what fuel is available?
Boire Field, KASH, is attended daily from 0700 to 2100 local time. Fuel available on the field includes 100LL avgas and Jet A, listed in airport data as A1+. The airport is towered, so operations outside published attended hours should account for tower closure and reliance on CTAF for lighting activation. Crews planning arrivals near the edges of the attendance window should verify current fuel service hours directly, since attendance and fuel availability can differ in practice. Nashua's field elevation is 200 feet.
How busy is Boire Field with business aviation traffic, and does it vary by season?
Boire Field, KASH, recorded 2,082 business aviation operations in 2025 out of 3,399 total annual operations, according to FAA TFMSC data. Traffic is not evenly distributed across the year: monthly business aviation operations ranged from a low of 118 in February to a peak of 237 in July, with the summer months of June through August consistently higher than the winter months. This pattern means dispatchers scheduling summer trips into Nashua should expect a busier operational environment than in January or February. The airport sits 135.24 nautical miles from the nearest major metro reference point.
