0' Grid at Edge of Airport Radius

[Parkerjh]

I assumed this was a glitch in Airmap but same data showing in Aloft.
This is Worcester, MA airport (Class D, yellow arrow)
At almost the entirely of the edge around the perimeter of the altitude restricted areas are 0' grids.
There's a very small few that aren't. But makes no sense to go from 100, 200, 300, 400' and then back to 0' furthest away from airport.

Any thoughts on why this is or if indeed a glitch of some sort?

I just looked on the ArcGIS website at the UAS Facilities map and it shows the same information. I think this is a screw up in the data when they converted to the quarter sections in a recent update of the Facilities Map. The old sections were halved vertically and horizontally giving 1/4 sections now.

Yes - the entire circumference; that has to be an error. A cursory look didn't reveal any other airports with that issue.

Reach out to [email protected] and they can steer you in the right direction. You can also try calling the ATC manager and ask why the entire UASFM is ringed by 0 grids.

Thank you for the suggestion @Vic Moss

So now I am more confused than ever on why that exists like that.
I have no idea how to contact the local and regional airspace manager to ask what is going on.

Those are absurdly poor answers from the help desk, which is rather unusual. It appears he just couldn't be bothered. You could try calling to see if you get a more reasonable answer, or try your local FSDO.

Please forward that email to me. I'll reach out to my contacts at the UAS office. [email protected]

His answer is obviously incorrect. I've never seen another UASFM ringed with 0 grids. But he may mean that the airport is. It looks like he misunderstood the question.

It looks like he first misunderstood the question, then got it but couldn't be bothered to investigate what is obviously a mistake.
