At what angle should a handheld flare be fired?

The correct angle for firing a handheld flare is 60 degrees above the horizon. This angle is optimal for maximizing the visibility of the flare while ensuring that it travels high enough to be seen over a significant distance. When fired at this angle, the flare ascends to a peak height where it can be observed by potential rescuers from various distances and directions.

Firing the flare at 60 degrees allows it to stay in the air longer, creating a more effective signal for help. The angle strikes a balance between altitude and range, making it less likely to be obscured by obstacles, such as the ship’s superstructure or the surrounding terrain if fired from a land-based location.

In contrast, alternative angles such as 30 or 45 degrees would not achieve the same optimum height or visibility. A higher angle like 90 degrees may cause the flare to fall back to earth quickly, reducing the distance it can be seen and diminishing its effectiveness as a distress signal. Therefore, 60 degrees is the best practice for ensuring the flare serves its purpose effectively.
