Which subsystems are involved in navigation and flight guidance on the 737?

Explanation:
In normal operation, navigation and flight guidance are driven by two active subsystems: the Flight Management System and the Autopilot with Flight Director. The FMS handles route plan, navigation data processing, and performance; it builds the guidance cues that describe how the aircraft should fly the selected path. The Autopilot with Flight Director uses those cues to actually steer the aircraft or to provide the pilot with visual guidance commands. Displays like MFDs/EFIS show the data but don’t perform guidance themselves, while VOR/ADF receivers supply raw navigation signals that feed the system rather than provide direct guidance. Standby instruments are backups, not part of normal navigation and guidance. So the best choice is the combination of FMS and Autopilot with Flight Director.
