How can the pilot receive the latest NOTAMs for the TUS LAX flight?

The correct approach for the pilot to receive the latest NOTAMs for the TUS to LAX flight is to utilize the appropriate frequency designated for this purpose. Generally, 123.9 is a common frequency used for general aviation and can include information such as NOTAMs, advisories, and other flight-related information communicated between pilots and ATC (Air Traffic Control) or other aviation services.

Using a frequency like 123.9 allows the pilot to access timely information directly and facilitates communication with other aircraft in the vicinity, which is crucial for situational awareness and safety. This method is especially relevant for flights operating in terminal airspace or nearby uncontrolled airspace where continual updates may be crucial.

While contacting ASOS or using a flight services station are also valid methods to obtain NOTAMs, they may not provide the real-time updates that can be exchanged over the designated frequency. The certain frequency directly connects pilots with essential flight information, making it an efficient choice for staying informed about NOTAMs during the flight.
