What defines CASE 2 flight operations?

CASE 2 flight operations are characterized by specific meteorological conditions that allow for safe flight but require certain precautions due to reduced visibility. This involves overcast skies with visibility limited to up to 5 nautical miles and cloud ceilings ranging from 1,000 to 3,000 feet.

In these conditions, pilots can operate but must remain vigilant, adhering to standard operating procedures that are designed to ensure safety in less-than-ideal weather. This level of flight operation requires more precise planning and awareness compared to clear, unrestricted conditions, as the potential for obstacles and challenges in navigation is heightened.

In contrast, the other options describe either clearer conditions (like clear skies or partly cloudy weather) which would fall under different CASE levels, or poor visibility conditions (like foggy conditions) that would indicate even more restrictive flight operations. Understanding these operational cases is critical for mission planning and ensuring the safety of flight operations under varying weather conditions.
