Definition
A commercial company that compiles, formats, and distributes the navigation data used by aircraft avionics. The provider gathers official source information — such as airport, navaid, airway, approach, and airspace data published by aviation authorities like the FAA and ICAO — converts it into the proprietary format required by a specific avionics manufacturer, and issues regular updates (typically on the 28-day AIRAC cycle) to pilots and operators.
Plain English
The company that builds and supplies the navigation database your GPS or FMS uses, and sends out the updates you load every 28 days.
Context Anchor
Seen when discussing airborne navigation databases, GPS updates, flight management systems, and the source of the data loaded into cockpit navigation equipment.
Why Pilots Care
Outdated or incorrect data from a provider can lead to navigation errors during instrument procedures.
Analogy
A database provider is like a map publisher for your aircraft’s navigation equipment. The provider does not fly the airplane for you, but it supplies the information the equipment displays.
Intuition Check
Do not assume “database provider” means the FAA itself or the pilot entering points by hand. In this context, it means the organization that packages and supplies aviation navigation data for the aircraft system.
Example Sentence 1
Before the flight, the pilot confirmed the navigation database from the provider was current for the 28-day cycle.
Example Sentence 2
Database providers issue regular updates to keep approach procedures current in the aircraft systems.
