## How the Term Is Used in Aviation

Terrain Awareness and Warning System, or TAWS, uses aircraft position, terrain databases and other inputs to warn crews of potentially hazardous terrain proximity.

Aviation Glossary

**Term:** TAWS

**Category:** Airline Operations & Navigation

## How It Is Used in Flight Operations

TAWS 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

It is designed to reduce controlled-flight-into-terrain risk and includes predictive functions beyond earlier basic ground-proximity systems.

## 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.
