VFRnav can be downloaded and tested for free.
During the 60-day trial period, all features are fully available.
After the trial period has ended, the app can be permanently licensed. The purchase of the usage licence includes 12 months of free access (update period) to all existing map sets and their updates, retrieval of weather and route information, and all other online services. After the update period, this can be extended by a further 12 months. VFRnav itself, however, remains fully operational regardless.
Note:
VFRnav does not include any automatic subscriptions. An extension only occurs at the user’s express request.
