What does DFS stand for?

Explanation:
Departure From Specification is the term used to denote a deviation from the approved design or mission parameters. In re-entry operations, the vehicle must stay within a defined envelope of limits for parameters like trajectory, angles, velocity, and thermal loads. A DFS indicates that one or more of these parameters have strayed outside the specified limits, signaling that corrective actions or abort procedures may be required. This concept is about detecting when the system is no longer operating as planned, so controllers can respond promptly. The other options don’t reflect a standard term for a deviation from approved performance; Data From Specification, Division For Specification, and Dynamic System Failure do not convey leaving the established spec in the way DFS does.
