🔍 Key Concepts

• Structure and use of the International Code of Signals (ICS) • How time, position (latitude/longitude), and courses/bearings are usually expressed in standard maritime notation • Meaning of the prefix letters (like 'SA') and RQ within ICS messages

💭 Think About

• Look at each part of the signal: 'SA', 'T1035', and 'RQ'. What does each part usually represent in the ICS, and how are they normally combined? • Compare how a latitude, a longitude, a time, and a true course are typically written in nautical communications. Which one best matches the pattern 'T1035'? • Think about what 'RQ' generally indicates in the International Code of Signals: does it usually turn a statement into a question, or does it change something else?

✅ Before You Answer

• Verify how times are usually written (e.g., 4 digits, with or without a leading letter) in ICS examples. • Check how latitude and longitude are normally formatted in ICS (degrees, minutes, N/S, E/W) and see if 'T1035' fits that pattern. • Confirm the general function of the RQ group in ICS — does it signal a request/question or something related to course or time changes?
