Question 1 of 27070

With respect to automatic identification systems (AIS), which information is required to be broadcast every 1 to 10 seconds?

🔍 Key Concepts

• Dynamic AIS data vs static AIS data (what changes often vs what rarely changes) • Update rate for position-related information when a vessel is underway • Which items are tied to the ship’s identity vs its real‑time movement

💭 Think About

• Which of the listed pieces of information would logically need to be updated as often as every few seconds while a vessel is moving? • Which items are more ‘fixed’ identifiers that don’t need rapid, repeated transmission? • Look at which answer choices mix a permanent ID (like MMSI or call sign) with something that actually changes second‑to‑second.

✅ Before You Answer

• Identify which options include movement‑related data such as position, speed, or course. • Eliminate any options made up only of static identifiers (things that never or rarely change). • Remember that AIS frequently refreshes data that affects collision avoidance and situational awareness, not just who the ship is.
