What action should a pilot take if they are unsure of their position?

When a pilot is unsure of their position, referring to navigation charts is the correct course of action because it allows the pilot to cross-reference their current flight data with established routes, waypoints, and landmarks. Navigation charts provide essential information on airspace structure, terrain, and airports, empowering the pilot to accurately determine their location based on visual cues or instrument data.

By using navigational charts, a pilot can also identify alternative routes if needed and prepare for safe navigation towards their intended destination. This practice aligns with standard aviation protocols that emphasize situational awareness and decision-making based on reliable sources of information.

The other options do not provide a reliable solution to the problem of position uncertainty. Continuing to fly while monitoring instruments may lead to further disorientation. Consulting a flight attendant yields no navigational expertise. Performing a descent without knowing the aircraft's position could introduce risk, especially if the area below is not suitable for such actions. Thus, utilizing navigation charts is the most effective and safest option in this scenario.
