What communication action is implied by saying "Read back"?

The phrase "read back" in communication typically implies a confirmation of understanding between parties. This action requires the listener to repeat or recapitulate what was communicated to ensure that the details were accurately understood and acknowledged. It serves as a method of verifying that both individuals are on the same page, reducing the likelihood of miscommunication. By encouraging the recipient to articulate the information, it confirms that the message was received correctly and allows for clarification if there are any discrepancies in the transmitted information. This practice is especially important in scenarios where clarity is essential, such as in aviation or emergency services, where precise communication is critical.
