contained in the Obstacle Database.

Navigation Database

As explained in the "Premature Descent Alerting (PDA)" section (page 40), the Garmin TERRAIN pre-
mature descent alerting (PDA) algorithms utilize data contained in the Navigation Database. It is therefore
important to also have the latest Navigation Database installed to ensure correct TERRAIN alerting.
