Class D airspace cannot be changed by NOTAM action; such changes require a formal regulatory rulemaking process. NOTAMs are for temporary changes, while permanent alterations to airspace classifications undergo a more official procedure.
The question regards airspace classification and the regulatory processes that govern changes to that classification. Continuously active surface areas, such as Class D airspace, cannot be changed by NOTAM (Notice to Airmen) action, but only through regulatory rulemaking processes. NOTAMs are designed to inform aircraft pilots of temporary changes, such as hazards or temporary restrictions, but not for permanent or long-standing rules or definitions of airspace.
Airspace classifications are established for various reasons, such as the level of air traffic control service or air traffic patterns, and changes to such classifications involve a more formal process that includes assessments, stakeholder engagements, and official amendments to regulatory documents.
