Navies still train navigators to use charts and dead reckoning because satellite systems can fail. A functioning electronic console can conceal a gap in the bridge team's ability to navigate without it. A guest recalls hearing about a US Navy chief petty officer who asked a bridge crew how they would navigate after their console went down and received a blank response. The recollection is uncertain about the vessel type, but connects the incident with the return of pen-and-paper navigation training.

Why navigators still need charts and dead reckoning
Manual navigation keeps a ship moving when satellites or electronic consoles fail, but crews must practise those skills before an emergency.
