It’s engaged for DFCS IBIT. DFCS IBIT disengages it as part of its test (not modeled). So it is off for takeoff. 

 

This is according to NATOPS and I believe it's also stated in Hearblur's F-14A/B Checklist.

Same goes for for AFCS aircraft. OBC checks the pitch parallel auctuator, AP master switch has to be on for that.
