Question 1 of 27070

An icebreaker may use the code letter "K" to remind ships of their obligation to listen continuously on their radio. This signal may be made by any of the following EXCEPT __________.

🔍 Key Concepts

• International Code of Signals (ICS) methods of transmission (flags, lights, sound, radiotelephony) • What the code letter “K” represents in ICS and how it can be sent • Difference between visual signals and radio communications

💭 Think About

• List the standard ways an ICS letter signal (like “K”) can be transmitted between ships and see which option does not fit that pattern • Ask yourself whether “visual” is a broad category and how “light” and flags fit under it • Consider which option depends on actual radio equipment rather than line‑of‑sight signaling

✅ Before You Answer

• Verify which methods are explicitly recognized in the International Code of Signals for sending a single-letter signal like “K” • Check whether light signal and visual signal are essentially the same thing in this context or if one is redundant as a separate answer • Confirm whether radiotelephone is treated the same way as flags/lights/sound in ICS, or if it’s categorized differently from traditional code signals
