The settings page which provides a set of configurable parameters for the application.

On the iPhone and iPod this menu is located just right of the data source selection panel.

The unit fields are self explanatory; you can change the units of different types of variables. Any changes on this screen will reflect throughout the app so if you change the time to local, ETA times in the FMC will be given as local, and if you change speed to km/h the ground speed indicators will report in these.

The heading selector controls what source to use for heading for location services, if the direction of travelling (course) or the direction of pointing (compass).

The Air Traffic selector controls what source of traffic is used for the MFD TCA mode; VATSIM will show all aircrafts flying around you. In order to use this option your device needs to be connected to the Internet as the surrounding aircrafts have to be downloaded.

On the iPad the settings are joint together with the source selector:

The Navigation Data

By default AirTrack comes with an old / out of date AIRAC data cycle.

If you want the latest and most up-to-date navigation data for your FMC and flight sim experience, you can subscribe to Navdata from Navigraph and have access to the latest 28 day AIRAC cycle. AirTrack allows you to login to your account from within the app and download it onto the device for use in the FMC and EFIS / Navigation Display sections.

Please note that the data is for flight simulation only and must never be used in real flights. The data, even if current, may differ from the officially published data.

In addition and alternatively to this you can also download the FAA CIFP (Coded Instrument Flight Procedures) for free, although these only cover the United States.
