What should a pilot do if ATC informs them that minimums are below the required for the approach while they are inbound on the final approach segment?

When ATC informs the pilot that minimums are below the required levels for the approach while inbound on the final approach segment, the appropriate action is to continue the approach. This is based on the understanding that as long as the pilot has the necessary situational awareness and is able to keep the aircraft stabilized, they can decide to proceed. The pilot may have already determined that conditions up ahead are safe for landing or may have visual references to continue the approach.

Continuing the approach is also consistent with standard operating procedures, provided the pilot assesses that they are still within safe operational limits, thus making it a viable choice. They can ensure that they are adequately prepared for the situation should the visibility or weather conditions materially change before touchdown.

Choosing to cancel the approach and divert or climb to a holding altitude would be unnecessary reactions if the pilot feels able to continue safely. Similarly, requesting to circle to land is not applicable if the visibility or minimums do not support such a maneuver. The decision to continue the approach requires the pilot to exercise their judgment based on the current conditions and operational proficiency.
