Which description best matches the role of confirmation in cockpit operations?

• A. It is a post-flight record review.
• B. It is verifying the data only if time allows.
• C. It is verifying information before execution and requiring discipline to follow SOPs before activating what is loaded into the computer.
• D. It is an informal check with the captain's word.

Answer: (D)

Confirmation is a formal, disciplined cross-check done before taking any action that affects the aircraft’s systems. It ensures that inputs, data, and plans are correct and agreed by the crew before activation of automation or loading into the computer.

The description that best fits this concept emphasizes verifying information before execution and requiring adherence to SOPs before you activate what will run in the computer. This captures the proactive, standardized process that prevents misinputs and ensures everyone is on the same page before committing to an action.

Post-flight review is retrospective and not about pre-action checks. Verifying data only if time allows contradicts the safety mindset of always confirming critical information. An informal check based on the captain’s word lacks the formal cross-check, documentation, and discipline that confirmatory procedures require.
