DataRefs

Data references or "DataRefs" are the way a plugin reads X-Plane's internal variables, or exchanges data with another plugin.
Datarefs are identified by verbose string names (sim/flightmodel/position/latitude).

• Current listing of X-Plane DataRefs in HTML .
• Current listing of X-Plane DataRefs in plain text.
• Some complex datarefs have more information on the wiki - see Category:DataRefs for more info.

DataRefs can be accessed (read/write) via the XPLMDataAccess API.
