Final answer:
Flight crews may accept a visual approach if they have the airport or preceding traffic in sight, can maintain safe separation and descent, and the weather allows for clear visibility and satisfies regulated minimums.
Step-by-step explanation:
Flight crews may accept a visual approach provided certain conditions are met. These include having either the airport or the preceding aircraft in sight, and being able to maintain safe separation and continuous safe descent to landing. Additionally, weather conditions must allow for clear visibility and the flight crew must be able to navigate without relying solely on instruments, meaning that the ceiling and visibility must be at or above the minimums prescribed by the regulations or the operator's procedures. When a visual approach is accepted, it is the pilots' responsibility to avoid all other traffic and to stay clear of clouds while maneuvering the aircraft to land.
