What is the status of the PMU during a prohibited spin?

During a prohibited spin, the status of the PMU (Power Management Unit) is off because its primary role is to manage engine operations and maintain control under normal circumstances. In the event of a prohibited spin, which can endanger the aircraft's systems, disabling the PMU is a safety measure. This prevents the PMU from attempting to intervene or make adjustments that could exacerbate the situation, allowing the pilot to have direct control over the engine's parameters.

It's important to remember that in scenarios where normal operations are compromised, such as a spin, the PMU’s role needs to be suspended to avoid unwanted reactions from the engine, promoting safer handling by the pilot. This reflects the essential precaution taken in handling potentially hazardous aircraft maneuvers to ensure safety and control.
