Answer :
Final answer:
The instruction relates to aviation procedures where a pilot may proceed visually to land if the runway is in sight, but must perform a missed approach if they cannot maintain visual contact or for safety concerns. The correct option is c) Proceed visually and missed approach
Explanation:
The statement 'Proceed visually (if runway in sight has been called) or missed approach' pertains to the instructions given to a pilot during the final phase of the flight. When the runway is in sight, and the pilot is confident in the aircraft's position and the ability to land safely, they may continue to proceed visually towards landing. However, if the pilot cannot maintain visual contact with the runway, or if there are any other safety concerns, the pilot is expected to perform a missed approach, which involves following predefined procedures to climb and re-attempt the approach or divert to an alternate airport.
