Does the PMU provide engine protection during airstarts according to the provided information?

The correct answer states that the PMU does not provide engine protection during airstarts. This is an important aspect of the PMU's (Power Management Unit) operational capabilities. During an airstart, the primary function of the PMU is to control the engine's fuel flow and ignition in a way that allows for a successful restart in flight. However, it does not incorporate protection features that it typically would during normal engine operations for situations such as preventing damage caused by over-temp or over-speed conditions.

In normal operations outside of airstarts, the PMU actively manages and protects the engine to ensure that it operates within safe parameters, adjusting power output and fuel flow as necessary. However, in the airstart process, the focus shifts to simply achieving a successful restart, and the protective functions that the PMU provides during standard engine operation are not engaged.

This understanding is crucial for pilots, as it highlights the need for caution during airstarts, knowing that while the PMU will assist in restarting the engine, it will not safeguard against potential engine stressors that could arise during this unconventional operation.
