What should a pilot do when contacting the tower for traffic pattern entry?

When contacting the tower for traffic pattern entry, it is crucial for the pilot to mention the ATIS (Automatic Terminal Information Service) information they have received. This is important because ATIS provides essential updates about the airport, including weather conditions, runway information, and any pertinent notices that could affect air traffic. By confirming that they have the latest ATIS information, the pilot demonstrates awareness of the current conditions and compliance with standard procedures.

Providing this information helps the tower controller manage overall traffic more effectively, as they can make better-informed decisions regarding runway assignments and potential traffic conflicts. Additionally, it allows the controller to know that the pilot is familiar with the necessary details that have been broadcast, which contributes to safety and situational awareness in the busy environment of an airport.
