What purpose do figures serve in radio communication?

The purpose of using figures in radio communication is primarily to distinguish numerals from letters or words, ensuring clarity in conveying numerical information. This distinction is crucial because many words can sound similar over radio frequencies, which may lead to misunderstandings. By specifying figures, operators confirm that they are communicating numeric data accurately, which is vital for tasks like reporting coordinates, quantities, or operational details.

In radio communication, ensuring that messages are understood with precision is key, especially in situations where miscommunication can lead to operational errors or safety issues. This technique is part of standard procedures to promote effective communication in a clear and unambiguous manner.
