For years, the navigation databases for many FMSes (Flight Management Systems) were updated via floppy disks. In recent years, the updates have been stored on USB drives, and now vendors are transitioning to solid-state data loaders, USB devices, and wireless options.
Rockwell Collins and Honeywell, for instance, have done away with the unreliable and obsolete floppy disks. You’ll need a subscription to Honeywell, so an FBO can download the navigation database specific to your FMS.
A good time to update your navigation database is when your aircraft is down getting its FAA-mandated ADS-B (Automatic Dependent Surveillance-Broadcast) upgrade.
