Which of the following is NOT a function of NOTAMs?

NOTAMs, or Notices to Airmen, serve specific purposes in the aviation industry, primarily focused on the operational conditions affecting flight safety. They are designed to provide timely information that can impact flight operations, but do not typically cover standard operating procedures.

Instead, NOTAMs are used to communicate updates on runway conditions, inform pilots about temporary flight restrictions, and notify about changes in navigational aids. Each of these functions is crucial for ensuring that pilots and air traffic controllers have the necessary information to make informed decisions and maintain safety. The lack of coverage for outlining standard operating procedures in NOTAMs reflects the distinction between operational alerts and the established protocols and procedures that aviation organizations follow as part of their routine operations. Thus, the correct response highlights this limitation of NOTAMs, emphasizing their specific purpose in aviation communication.
