What is the phraseology for the callsign AAL52?

In aviation communication, the standard phraseology for referring to airline callsigns is critical for clarity and efficiency. The correct phraseology for the callsign AAL52 is "American fifty-two." This follows the convention of using the airline's name alongside the flight number. This practice helps avoid confusion, especially in environments where multiple flights are being coordinated simultaneously, as it clearly identifies the airline operator.

Using the full name of the airline, "American," ensures that all parties involved—air traffic controllers, pilots, and other personnel—understand exactly which airline is being referenced, reducing the risk of miscommunication.

Other options do not adhere to this practice of clarity. For example, "AAL fifty two" might be too vague since it uses the IATA code without the airline name, which could be less familiar to some individuals in the communication chain. Similarly, "American Airlines fifty two" is not the preferred phraseology as it adds unnecessary words that are not typically used in aviation communication. "AAL five two" also simplifies the callsign too much, which can lead to confusion. Thus, "American fifty-two" is the correct and preferred standard.
