In a fixed waste gate system, the proportion of exhaust gas going through the turbine is ______.

Explanation:
At the heart of a wastegate is the goal to control turbo boost by diverting some exhaust away from the turbine. In a fixed wastegate system, the amount of exhaust that bypasses the turbine is determined by a fixed, ground-calibrated setting—a spring-loaded valve that is adjusted and locked in place during ground maintenance. That setting determines how much exhaust goes through the turbine versus bypassed around it, and it does not respond to in-flight changes or pilot input. So the proportion of exhaust gas going through the turbine is effectively fixed by the ground calibration and remains constant during flight, aside from normal changes in overall engine exhaust flow.
