Interior Communications (IC) A School Test 3 Practice

Prowords are standardized short words or phrases used in radiocommunications to convey complex instructions quickly and unambiguously. They streamline verbal exchanges so a single term can indicate reception, understanding, or a requested action, which helps prevent miscommunication on noisy or busy radio channels. For example, Roger means the message was received; Wilco means you will comply; Over signals that you’ve finished transmitting and are awaiting a reply. This idea matches the description because it focuses on concise, agreed-upon language to communicate clearly. The other options describe a station identifier for encrypted channels, a weather term, or equipment used to encode signals—none of which define a proword.
