Definition
A navigation database stored in an aircraft's GPS or flight management system that contains navigation data — airports, runways, navaids, waypoints, airways, and instrument procedures — for the entire world rather than a single region. Because it covers every region, it consumes more memory than a regional database and may exceed the storage capacity of older receivers.
Plain English
It's the version of the navigation database loaded into the GPS that covers the whole planet, not just one part of it.
Context Anchor
Seen in discussions of navigation equipment, especially when explaining how much airport, route, and procedure information a unit can store.
Derivation
“Worldwide” means spread across the world. “Database” combines “data,” meaning stored information, with “base,” meaning a place it is kept and organized. Together, the term points to stored aviation information organized for use across a very large area.
Why Pilots Care
Some older or lower-capacity GPS units cannot fit a worldwide database in memory, so operators must choose a regional database instead. Flying outside the loaded coverage area means the navigation system won't have the procedures, waypoints, or airports needed for the flight, which can prevent legal IFR use of the equipment in that area.
Intuition Check
Do not assume “worldwide database” means every airport and procedure in the world is available and current in your unit. In this context, it means broad coverage, still limited by storage capacity, selected coverage area, and updates.
Example Sentence 1
Because the operator flies internationally, they pay for the worldwide database update cycle rather than the North American one.
Example Sentence 2
Storage limitations on older units may prevent loading the entire worldwide database at once.
