What action signals that a memorandum has been read by the crew member?

• A. Clicking on the confirmation link
• B. Signing a receipt
• C. Replying to the memo
• D. Noting in Altitudes

Answer: (A)

The main idea is that a memo is officially considered read when the recipient provides a direct, system-recorded acknowledgment. Clicking the confirmation link creates a timestamped read receipt tied to that crew member, giving an auditable proof the memo was opened and read. This is preferred because it provides clear accountability within the digital distribution system, which is essential for safety and compliance in aviation.

Signing a receipt is more manual and less integrated with digital memos, so it isn’t as reliable for proving the memo was read. Replying to the memo might show engagement or raise questions, but it doesn’t guarantee that everyone has read the content. Noting in Altitudes depends on a separate log and may not serve as a formal read acknowledgment.
