Data Set Output Table

The following table provides a brief description of the fields present in X‑Plane 10’s Data Set screen. Note that this list is current as of X‑Plane 10.30.

In this table, note that each group of data fields is labeled as it would be in the Data Input & Output window. For instance, to see the values of the “f-act” or “frame time” variables, you would consult the table and see that those variables are under the frame rate label. Simply check the frame rate box in the Data Input & Output to see those variables. Alternately, if you know you want frame
rate-related variables, you could consult the portion of the table under the frame rate heading to find out what data is available. Where the meaning of a label in the Data Input & Output window is not immediately obvious, a longer version of the label is given—for instance, “Simulator statistics (sim stats).”
