I learned to fly at this Class D airport in the Mid-nineties back when Daniel Webster College ran a flight school at the field. At the time, it was one of the busiest small airports in the Northeast, maybe the country.
The airport is located in beautiful Southern New Hampshire, and Asobo definitely got the feel of the area right. It's a wonderful place to fly, located just south of Mt. Monadnock, centrally located between Cape Cod and the islands and the lakes region of New Hampshire and Maine, so there's lots of interesting places to fly and plenty of hamburgers and ice cream to be eaten at a wide variety of airports all around.
Locally there's some cool airports to check out, such as Silver Ranch (KAFN) over by Mt Monadnock, Brookline (NH16), Pepperell (26MA) (I'll probably redo this airport as it's the local sky diving location, (maybe figure out how to add that comment to the ATIS for the airport? "Be aware of Sky Diving operations at Pepperell"...)), Keene, Skyhaven, Hanscom, the Cape and Islands ( Nantucket (KACK), Provincetown (KPVC), Martha's Vineyard (KMVY) and more). A really nice flight is from KASH to the other airport I've released on Lake Winnipesaukee, Lakes Region Airport (69NH). It's a half hour flight with some decent geography, especially up in the Lakes Region/White Mountains. Alton Bay on the south end of Lake Winnipesaukee has ice operations in the winter time. For a longer flight, check out KRKD in Rockland on the shore of Maine, home of the Owl's head transportation museum. I used to volunteer there in the summer during their events driving people across the airport to the museum.
v2.2.1 12/6/2020 - Added a couple flattens to remove some new hills that were added under the hangars in a couple of locations. Modified a hangar on the south side of the field. Added the LWcfg file back in as Asobo fixed their bug.
v2.2.0 11/06/2020 - *MAJOR UPDATE* A bug was introduced in v10.7.0/10.8.0 with the living world config subsystem which causes a CTD if you start at an airport other than KASH pretty much anywhere in at least the Eastern US and Canada. Removing the section assocated with the KASH_LWcfg.xml file from the layout.json will stop the CTD. This release does that, so you can just delete the old install and replace it with this. Unfortunately, it means there will likely be vehicles that normally aren't on the airport driving around.
v2.1.1 10/18/2020 - Minor revision, edited and properly sized the taxiway signs (I forgot the brackets for the surround around the location), and fixed the signs over by 14 to match what is actually there. Added lighting over by the tower shining on the apron, added another vehicle parking space where fuel trucks typically park in front of the hangar next to the hangar with the restaurant. I haven't confirmed with the airport authorities, but I extended Taxiway Frank to connect with Charlie by passing along the taxiway in front of the tower. I extended Taxiway Charlie along the taxiway in front of the North Hangars all the way to Echo. Added most of the rest of fencing, including gates (which I don't imagine work). Added the windsock over the Midfield Cafe
v2.0 10/15/2020 - This is a major revision of my previous release. It's still the same buildings as rev 1, but I completely redid the runways, taxiways, and painted lines, I added all the parking spot on the tarmac as well as nearly 150 spots to spawn from/AI; replaced/added fuel stations and redid the runway, landing, and taxi lighting.. There hasn't been a VASI on 32 in maybe 10-15 years, they replaced it with PAPI when they redid the runways, fixed that. I added all the taxiway signs I'm aware of, I redid the ambient traffic and got rid of the pushbacks and vehicles that you'd never see at this airport, and greatly reduced the ambient traffic. I also added the current IFR Approaches which were for some reason forgotten for this airport, even though airports of similar size and traffic density in the immediate area have their approaches. I've added some fencing, there's more to be added. I'll be working on getting back into the air starting this Friday, so I'll have greater access to the grounds to get even more detail going forward. It's not finished to my own expectations, but it's many times over improved in my estimation over the default. Expect to see further improvements over time (maybe I'll figure out how to import Google Maps 3D assets?).
