Data format

All data exchanged with the aviowiki API, both as part of a request’s body or of a reply’s body, are formatted using JSON.

You can find full details on individual objects in the Data Models section.

Units of measure

Aviowiki mostly uses the International System of Units for data served via the API.

The main deviation from this is the use of Celsius Degrees in place of Kelvin, for temperatures. This minor variation reflects the more operational use of our data, as compared to the scientific focus of the ISU.

As a general overview, these are the units of measurement used for different use cases:

Measure	Unit
Length	Metres
Mass	Kilos
Temperature	Celsius degrees
Coordinates	Decimal degrees
Horizontal Speed	Metres/Second
Vertical Speed	Metres/Second
