Can an aircraft operating under 14 CFR 135.223 begin an approach if the weather at the airport is below landing minimums?

An aircraft operating under 14 CFR 135.223 can indeed continue its approach if it is already on final approach, even if the weather conditions are below established landing minimums. This regulation allows pilots to complete their approach under certain circumstances, particularly when specific conditions are met, such as being in visual contact with the runway or having the necessary operational capabilities to land safely.

The concept of a final approach means that the aircraft is already committed to landing and is typically within a certain distance from the runway, where pilots can visually identify the runway environment. At this point, the situation allows for maneuvering decisions focused on safely completing the landing rather than the initial approach phase, where strict adherence to minimums is required.

In contrast, if the aircraft has not yet reached that final approach phase, pilots must wait until conditions improve to comply with regulatory requirements and maintain safety. This underscores the importance of maintaining awareness of weather conditions and regulatory standards throughout all phases of flight.
