What should be done if the visibility reported is below standard during an approach?

When visibility reported is below standard during an approach, aborting the approach is the correct course of action. This prioritizes safety, as visibility below minimums indicates that the pilot may not be able to see the runway or other important visual references necessary for a safe landing.

The approach criteria are designed to ensure that pilots have sufficient visual information to make a safe landing. If visibility falls below these established minimums, attempting to continue would increase the risk of an accident due to insufficient visual cues.

Choosing to abort the approach allows the pilot to reassess the situation, possibly diverting to an alternate airport where visibility meets the required standards. This decision aligns with the principles of safety and operational risk management, ensuring that pilots operate within safe limits.

The other options may pose unnecessary risks or do not adhere to standard flying protocols.
