Final answer:
A certified GPS for VFR should be used only to confirm a current map and should not be relied upon as the sole means of navigation.
Step-by-step explanation:
When using a certified GPS for VFR (Visual Flight Rules) navigation, the correct approach is to utilise it B) Only to confirm with a current map. Pilots should use their GPS in conjunction with traditional navigation techniques, cross-checking their GPS readings against up-to-date aeronautical charts. Relying solely on GPS for navigation can be risky since electronic systems can fail or lose signal. Therefore, it is important to maintain proficiency in map reading and pilotage to ensure safety during VFR flights.
