Which mode is identified as the mission number and ID of individual Aircraft by specific tail number?

The mode that is primarily used to identify an aircraft by its specific tail number is known as Mode 2. This mode is designed for the transmission of individual aircraft information, such as the mission number and identification linked to the specific tail number.

Understanding the functionality of the different modes is crucial. Mode 1 typically transmits a basic information code that does not include the specific tail number. Mode 3 is commonly used for air traffic control identification, allowing for a broader range of operations, including responses that help identify aircraft in a general area but not specific to their unique tail number. Mode C is utilized for altitude reporting in addition to identification but does not provide the specific tail number context either.

Therefore, Mode 2 is the accurate mode associated with indicating the mission number and ID of aircraft tied specifically to their tail number.
