When advising pilots of hazardous weather, controllers must provide information for conditions that affect operations within what distance?

When advising pilots of hazardous weather, controllers are required to provide information on conditions that affect operations within a distance of 150 nautical miles from the affected area. This range is critical as it allows pilots to make informed decisions regarding flight paths, altitude adjustments, or potential diversions to ensure safety.

The 150 nautical miles threshold is based on operational standards that recognize the need for timely and relevant weather updates, enabling pilots to navigate effectively around hazardous weather conditions. By adhering to this guideline, air traffic controllers ensure that pilots are adequately informed of any significant weather phenomena—such as thunderstorms, turbulence, or icing—that could impact their flights well before entering these zones.

This distance allows for a proactive approach to flight safety, encouraging effective communication and ensuring that pilots have access to necessary information as they plan their flight routes. The other distances provided in the options exceed the operationally required range, which may lead to unnecessary alarm or congestion in communication without enhancing safety protocols.
