What that verdict means here
Pilots are asked, not ordered, to avoid this area. There is nothing to apply for; the request is the whole of it.
⚠️ § 107.41, the ATC-authorization rule quoted on the Class B, C, D and E-surface pages, is not the rule that governs this symbol, which is why it is not quoted here.
