🔍 Key Concepts

• Purpose of distress signals – what they are meant to communicate and to whom • Conservation of pyrotechnics – limited number of flares and rockets on board • Timing and visibility – day/night, weather, and presence of potential rescuers

💭 Think About

• In a real emergency, would you want to fire all your signals on a fixed schedule, or at a time that maximizes the chance someone sees them? • Think about what happens if you use up your flares before any ship or aircraft is near enough to see them. • Which option best matches how a good lookout would time the use of a signal so it is most effective?

✅ Before You Answer

• Check which choices talk about fixed time intervals versus actual rescue opportunity. • Consider that distress pyrotechnics are limited resources that cannot be replaced at sea. • Ask yourself: In poor visibility or with no vessels/aircraft nearby, would it be smart to use up flares on a clock?
