Which description best matches how confirmation is exercised in cockpit procedures?

• A. It only applies to flight planning
• B. It is unnecessary during normal operations
• C. It is verifying the data after it is loaded
• D. It is verifying information before execution and requires discipline to follow SOPs before activating what is loaded into the computer

Answer: (D)

In cockpit procedures, confirmation is the step of verifying critical data and settings before you take action, acting as a safeguard against acting on incorrect inputs. The best description is that this involves checking information before execution and following standard operating procedures with discipline before activating anything that the aircraft’s computers will use.

Think about loading routes, performance data, altitudes, speeds, or navigation parameters into systems like the FMS. You verify that what’s loaded matches the plan and the clearance, then only proceed to activate it. This pre-execution check helps catch errors early, so the automation behaves exactly as intended.

This isn’t limited to flight planning, and it isn’t something you skip during normal operations. It’s essential throughout all phases to prevent misprogramme or misinput from driving the aircraft’s systems. Verifying after data is loaded is too late—the action has already been set in motion, so the critical safety step is to confirm before activation.
