Plan Transitional Field Stress Factors was a technical manual. In this manual, an engineer was taught the methodology for planning ahead and implementing a plan wherein the field stress compensators adjust to the variable nature of the subspace warp field. A copy of this manual was stored in the Subspace Warp Field Overview, a folder in the Engineering Systems Database, aboard the USS Enterprise-D in 2366. (TNG: "Booby Trap" , okudagram)
