Final answer:
Changes in the operational hours of part-time surface areas at airports require a Distant NOTAM, with coordination on its issuance being the responsibility of the managing facility working in accordance with the US NOTAM Office as per FAA Order JO 7930.2.
Step-by-step explanation:
For facilities whose surface area is listed as part time in the Airport/Facility Directory (AFD), such as Class D at certain times and Class G at others, changes in the hours of operation of these surface areas require a Distant NOTAM (Notice to Airmen). The managing facility shall coordinate civil NOTAM issuance with the United States NOTAM Office (USNOF) in accordance with FAA Order JO 7930.2. This coordination ensures that all airmen have access to the latest and most accurate information concerning airspace classifications and hours of operation to maintain safety and efficiency in national airspace.
For facilities whose surface area is listed as part time in the Airport/Facility Directory (AFD) (e.g., Class D part of the time; Class G another), changes in the hours of operation of surface areas require a NOTAM. AFD shall coordinate civil NOTAM issuance with FAAO JO 7930.2.
