On a clear day, the smoke from the MK124 flare can be seen up to how many nautical miles?

The MK124 flare is specifically designed to function as a signaling device, commonly used by mariners and aviators in distress situations. On a clear day, the smoke emitted from the MK124 flare can typically be seen up to 5 nautical miles. This visibility range makes it an effective tool for attracting attention from rescuers or nearby vessels.

This capability is crucial in emergency situations where timely detection can significantly impact the chances of rescue. The clarity of the day, along with the contrasting color of the smoke against the sky and surroundings, contributes to this visibility range.
