Several vessels are at an anchorage. You wish to communicate with the vessel bearing 046°T from you but do not know the vessels call letters. Which flag hoist should NOT be used to establish communications?
Official USCG Answer & Rule Citation
Correct Answer: Option C — RQ A046
International Code of Signals procedures dictate that signaling a specific bearing alongside an identity or call sign utilizes designated prefix groups; however, combining 'RQ' (meaning 'I should like to communicate with...') with a relative bearing 'A046' is improper syntax for flag hoists.
