What is the Prop RPM Red display maximum range with the associated "Left or right engine" aural cue?

The maximum range for the Prop RPM Red display with the associated "Left or right engine" aural cue is accurately identified in the context of maintaining optimal engine performance and ensuring safety during flight operations. The specified range of 2000-2040 RPM with a duration greater than 7 minutes indicates that while the engine is operating within this RPM range, this behavior may be permissible for a longer duration without significant risk.

This range is critical because operating an aircraft engine within certain RPM thresholds minimizes wear and tear, optimizes fuel efficiency, and ensures that the engine does not approach conditions that could cause damage or failure. The 7-minute duration signifies that the engine can remain in this range safely for an extended period, which is essential for operational considerations when planning missions or functions that involve prolonged engine use.

The alternative choices either present incorrect RPM limits or suggest durations that are longer or shorter than what is considered safe for the specified RPM range, which are less desirable in managing the engine's performance effectively.
