When flying a STAR, what must pilots do if the SIDON VORTAC visibility is limited?

Following the Standard Terminal Arrival Route (STAR) while maintaining situational awareness is crucial when visibility at a navigational aid like the SIDON VORTAC is limited. Pilots are trained to navigate under a variety of conditions and must be able to adapt their procedures in response to changing visibility.

Maintaining situational awareness means staying informed about the aircraft's location, the surrounding airspace, and any relevant weather conditions. This allows pilots to execute the STAR safely while remaining prepared to make necessary adjustments based on visibility and other factors. For instance, they may be able to rely on other navigational aids or visual references to navigate safely to their destination.

In this scenario, it's important for pilots to remain flexible and prepared to decide on alternative approaches or procedures while complying with air traffic control instructions. This approach balances safety and compliance with current visibility conditions, making it the most appropriate response to limited visibility rather than making drastic maneuvers or holding indefinitely.
