That was near my work, up on a mountain a bit south and east of alamogordo, the b4uflyapp said that one when there, and I couldn't see the restriction anywhere on the sectional. See attached with the red dot.
I thought the b4ufly app was published by the FAA? It seemed like the app contradicted the sectionals. Reading the sectionals isn't too difficult, though I don't do it enough to make it second nature. I was pretty stumped since there was no notes on the above flight areas that I saw and...
I have my b4ufly app, and it says entire towns near me not to fly. Though I double check the sectionals and it is special use defined by the following codes:
R-5109A
R-5017F
R-5107G
But other R- numbers are on sectionals but not the above ones?
The areas are on here...
