When firing a pyrotechnic distress signal, what is the proper direction to aim it?

The correct answer focuses on the need for the pyrotechnic distress signal to be fired in a direction that maximizes visibility and effectiveness for rescuers. Aiming the signal at an angle greater than 60 degrees above the horizon, and preferably into the wind, ensures that the signal's light and smoke can be seen from a distance and are not obscured by the marine environment.

Firing the signal upwards helps it ascend high enough into the atmosphere, where it can achieve a broader visibility range. The preference for aiming into the wind aids in ensuring that any smoke, if applicable, is carried away from the source, allowing the signal to be more conspicuous and to avoid being blown back towards the launching position. This angle and direction also mitigate the risk of the signal coming down near the vessel or causing concern among crew members who may be mistakenly alerted to a danger that doesn’t correspond with distress.

Addressing the other options, firing directly into the water would not provide any visibility to rescuers and could render the signal ineffective. Aiming level with the horizon could limit the signal's reach and visibility, especially if obstacles block the line of sight. Similarly, firing downwind of the ship doesn't maximize the signal's visibility and may not keep the signal clear
