Which approach control frequency is indicated for the TNP-DOWNE4 Arrival with LAX as the destination?

The TNP-DOWNE4 Arrival is a specific Standard Terminal Arrival Route (STAR) used for aircraft approaching Los Angeles International Airport (LAX). The correct approach control frequency for this arrival procedure is crucial for coordinating the descent and approach of the aircraft as it transitions from en route airspace to terminal airspace.

In this case, the frequency of 124.05 MHz is designated for approach control services managing traffic arriving at LAX, providing the necessary communication for pilots to receive instructions related to their descent, approach, and landing. This frequency is specifically assigned for the operation and management of arrivals into LAX, making it the appropriate choice for pilots and dispatchers to use when planning this particular STAR.

Selecting the proper frequency is a fundamental aspect of ensuring safe and efficient flight operations, as it allows for coordination among multiple aircraft arriving at a busy airport like LAX. The other frequencies listed in the choices are associated with different sectors or types of operations and are not suitable for this specific arrival procedure. Thus, understanding the correct frequency reinforces the importance of communication and situational awareness in air traffic management.
