Heliports and Airports that do not contain a runway of greater than 5000 feet will be excluded from the Worldwide Navigation Database. All associated data with excluded airports (communication frequencies, approaches, runways, etc.) will also be excluded.

Beginning with Cycle 1911 (effective October 10, 2019):

Garmin will discontinue the Worldwide Navigation Database for the affected products listed above. The Transatlantic Database will be offered in place of the Worldwide Database.
