Obstacles 200 feet andhigher are included in the obstacle database. The rotorcraft databaseincludes all reported obstacles regardless of height. It is very important tonote that not all obstacles are necessarily charted and therefore may notbe contained in the obstacle database. This database is updated on a 56-day cycle. Obstacles will still be shown after the database has expired.Several obstacle database options are available. Obstacle databases createdfor GTN software version 5.10 or later include all power lines or only HOTlines depending on the type of obstacle database installed.
