Aviation Glossary

**Term:** ADS-B

**Category:** Airline Operations & Navigation

## How It Is Used in Flight Operations

ADS-B is used within dispatch, flight planning, crew procedures, aircraft approvals or air traffic operations depending on the subject. Operators must apply the version and approval basis recognized by the relevant aviation authority.

## Operational Effect

Mandates and equipment standards differ by airspace, so operators must check regional requirements for ADS-B Out and related capabilities.

## Approval and Dispatch Considerations

Equipment capability alone may not be sufficient. Operator approval, crew qualification, maintenance status, database currency, route authorization and company procedures can all affect whether the capability may be used on a specific flight.
