What must a pilot do if they wish to use the FMS for approaching a non-EGPWS airport?

When using the Flight Management System (FMS) for approaching a non-EGPWS (Enhanced Ground Proximity Warning System) airport, confirming the database accuracy or waypoint verification is crucial. The FMS relies on a database that contains information about airports, navigation aids, waypoints, and procedures. If the database is outdated or inaccurate, it could lead to navigation errors, especially in unfamiliar or non-EGPWS environments where the pilot may not have the additional safety net provided by EGPWS.

By verifying the waypoint data, which includes confirming that the waypoints and approaches listed in the FMS align accurately with current aeronautical charts and the operational status of the airport, the pilot ensures that the navigation system is reliable. This step minimizes risks and promotes safe operations, particularly in situations where standard reference points and automated guidance (like those offered by EGPWS) are not available.

The other options have merit in their contexts, but they do not directly address the necessity of ensuring the FMS database's reliability for approaching non-EGPWS airports. While using updated charts is always a good practice, without confirming the data's integrity within the FMS itself, relying solely on charts could lead to potential conflicts during navigation. Similarly, standard navigation techniques provide
