With this native iPhone app you can create ICAO flightplans and file them with the authorities. Flightplans can also be saved as a template, so that you can later on create a new flightplan based on the template. The app is part of the AeroPlus software solution offered to flightschools and aeroclubs, so you need an AeroPlus account in order to use this app.
