What must the visibility be for the SIC to conduct takeoffs and landings after 100 hours in type?

For a Second-in-Command (SIC) to conduct takeoffs and landings after completing 100 hours in type, the visibility requirement is that it must be greater than 1 statute mile. This regulation is established to ensure safety and operational competency, as visibility plays a critical role in the SIC's ability to effectively manage takeoffs and landings, especially in varying weather conditions.

Conducting operations with visibility less than or equal to 1 statute mile limits the available visual reference points, which can increase the risk of incidents during critical phases of flight. By requiring that visibility be greater than 1 statute mile, safety protocols ensure that the SIC has ample opportunity to visually identify and react to necessary cues during these critical maneuvers. This regulation is in place to protect both the crew and passengers by enhancing situational awareness.
