If I do a NOTAM search for a given airport (I'll use KMMK in Connecticut) on the FAA website I find a whole list of issues to be mindful of concerning work on the facility proper.

That same search on Skydeamon for a route direct to that same airport pulls up none of this information. All I seem to get is ATS Route closures, which as a low flying VFR pilot, I have no real use for.

Where is Skydeamon pulling this information from and can it do a better job?

Thanks

The other navigation software you refer to is probably designed for the US market, so includes support for US peculiarities. SkyDemon does not; we only have basic support for US operations.
