Which statement is true about the example mission's ID 0401?

• A. It represents the mission number for the example message
• B. It represents the primary control frequency
• C. It represents the geodetic datum
• D. It represents the departure airport code

Answer: (A)

Mission identification is used to uniquely reference a specific operation in planning and messaging. The ID 0401 functions as the mission number for the example message, giving you a concise handle to track and retrieve all related details in briefs, schedules, and data exchanges. It isn’t the primary control frequency, since frequencies are about radio communication settings. It isn’t a geodetic datum, which would define the map’s reference coordinates. It isn’t an airport code, which would identify a departure or arrival airport. So, the statement that 0401 represents the mission number for the example message is the correct interpretation.
