If a waypoint is not recognized by the database, how will it be displayed?

When a waypoint is not recognized by the navigation database, it is represented by a specific format that indicates the waypoint is not valid or cannot be found. The correct representation of such a waypoint is shown as “?VKA.” This format helps pilots and navigators quickly identify that the waypoint they are trying to use is not included in their flight management system's database.

The prefix "?" indicates that the waypoint is not recognized, while the subsequent characters represent the name of the waypoint. This allows for identifying which waypoint is in question, even if it is not recognized. Using this format, pilots can take appropriate action, such as verifying the waypoint details or making necessary adjustments to their flight plan.

In contrast, options like “???” and “XXX” generally indicate an entirely unknown or invalid entry, but they do not specify the intended name of the waypoint. The single question mark “?” is less informative than “?VKA,” as it does not provide any identifier.
