What must visual observers do upon detecting conflicting air traffic?

Visual observers play a crucial role in ensuring the safety and awareness of aircraft operations, particularly when it comes to detecting conflicting air traffic. Upon identifying another aircraft in proximity, the primary responsibility of the visual observer is to promptly communicate this information to the pilot. Timely communication is essential because it allows the pilot to make informed decisions about their flight path or take evasive action if necessary.

Failure to relay this information can lead to dangerous situations, including potential mid-air collisions, especially if the conflicting aircraft is moving closer or poses a threat. The nature of aviation requires constant vigilance, and part of that vigilance includes ensuring that all relevant parties are aware of any potential hazards in their vicinity. Thus, effective communication between visual observers and pilots is vital for maintaining safe operations in the airspace.

In contrast, ignoring distant aircraft, waiting for the pilot to notice on their own, or only reporting critical conflicts could significantly increase the risk of accidents and defeat the purpose of having visual observers in the first place. The emphasis on timely reporting aligns with standard operating procedures aimed at heightening situational awareness and promoting proactive safety measures.
