🔍 Key Concepts

• Morse flashing light procedure for sending numbers and dates • How dates are normally written** in navigational signaling (day–month vs month–day)** • Difference between signals used for position (longitude/latitude) and those used for dates or plain numbers

💭 Think About

• Ask yourself: in international maritime communication, when a four-character group starts with a letter like 'D' followed by four digits, what does that leading letter usually indicate? • Think about how months are represented in code: does '09' more commonly mean September (9th month) or a time of day? • Which of these options (date, distance, longitude) would most logically be sent as a simple coded group like 'D0910' without any additional symbols such as N, E, W, or units?

✅ Before You Answer

• Check how numeral/date groups are formatted in the International Code of Signals or flashing light procedures. • Verify whether position (longitude) reports normally include hemisphere (E/W) and degrees plus minutes, not just a bare four‑digit group with a single letter. • Confirm whether long distances in miles are usually sent with a unit indicator rather than only digits.
