Predicts how your craft will behave during complex maneuvers like rolls or high-speed turns.

In "stock" KSP, breaking the sound barrier is just a matter of throttle. In FAR, it is an event. As you approach , drag spikes exponentially due to wave drag . Designing for this requires "Area Ruling"—shaping your fuselage to ensure the cross-sectional area changes smoothly—or your plane may simply refuse to go any faster, no matter how many engines you bolt on. 3.
