Obstacle databases are sold in combination with a license and published once or twice per year. They are valid until the expiration date specified on the applicable webshop page, which is around one year from when they were published. The expiration date of the installed obstacle database is also shown on the connected FLARM Compatible display.
Latest on the expiration date, the obstacle database has to be renewed by purchasing a new obstacle database license in the webshop.
For larger customers, we are also offering obstacle database updates every 2 or 4 weeks according to the AIRAC-system.
