True or False: Crewmembers should stop using own-ship display when discrepancies greater than 30 meters are observed.

The statement is true because when crewmembers observe discrepancies greater than 30 meters between their own-ship display and other navigation data, it indicates a significant error in positioning information. Relying on compromised data could lead to confusion and potentially unsafe situations during flight operations. By stopping the use of the own-ship display, crew can seek to verify their position through alternative means or rectify the issue before continuing with navigation. This protocol ensures safety and helps maintain situational awareness in the aircraft's operations.
