SimVars are “simulation variables” and they are the way that third party APIs and add-ons can get information about the current state of the simulation. In general these variables are used to control aircraft behaviors by permitting you to retrieve data about things like weather conditions, position, or aircraft status, and in many cases they can also be used to modify something within the simulation, in particular aircraft instruments and controls - although they can also have many other purposes within any add-on package.
