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 2001 AIRAC data cycle. The data can be updated to a more recent cycle using the built-in Navigation Data manager page.

If you want the latest and most up-to-date AIRAC cycle for your FMC and flight sim experience, you can visit Navigraph, purchase an FMS Data set. Within the FMS Data Manager app there will be a pop-up which says "Show Access Code for ..."; select AirTrack and note down or copy-paste the token.

Then select "Navigation Data", submit your token and download the FMS data directly into your device or paste it to the Navigation Data section of this web site (after logging into your Air Account) to make it available on your device automatically.

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 official published data.

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