What confirmation is necessary for the GPS during a cockpit check?

• A. Ensure the GPS is charging properly
• B. Confirm database is not expired and set
• C. Check the GPS is receiving signals
• D. Validate the backup GPS is functional

Answer: (B)

The necessary confirmation during a cockpit check for the GPS is to confirm that the database is not expired and set. This is crucial because the GPS relies on updated data to provide accurate navigation information. An expired database could lead to errors in navigation, as it might not reflect current airspace changes, new obstacles, or updated procedures. Pilots must ensure that their navigation databases are current and properly loaded to ensure the reliability and safety of their navigation system during the flight. While it is important to check that the GPS is charging, receiving signals, and that any backup GPS systems are functional, these aspects do not directly assess the critical data accuracy that the navigation database provides. The primary concern for safe navigation is ensuring that the information used by the GPS is the most current, making the confirmation of the database status essential before flight.
