If no flight plan is loaded, which block remains unpopulated?

Explanation:
Steering guidance is produced from a loaded flight plan. Without a flight plan, there’s no defined route for the autopilot or flight director to follow, so the steering cues can’t be generated and the Steering block remains empty. The NAV block can still show navigation data from the nav sources, the GPS block can continue to display position and satellite information, and the FMS can access its database and status even if no plan is loaded. In short, guidance requires a defined route, and that’s why the Steering block stays unpopulated.
