•

Valid terrain/obstacle database

FEATURE LIMITATIONS

•

Alerting functions are dependent upon the configured terrain alerting
options

•

Terrain Alerting functions do not provide aural alerts

5.14 Terrain Configurations

Terrain Alerting adds Forward Looking Terrain Alert (FLTA) and Premature Descent
Alert (PDA) functions. These include visual alerts when the aircraft flies below an
