Red line

Red line is a term used to describe the maximum safe output a set of engines can produce when used on a certain ship. While most engines are designed to exceed their posted redline slightly and for a limited amount of time, it's recommended to only be done in an emergency, and for those engines be thoroughly examined prior to being used again.

United Stars Military personnel who exceed the redline limits of their vehicle unless in active combat or another emergency, would be subject to facing a hearing to see if that action was justified.
