Final answer:
The operating limits of a propeller system include inspection, maintenance, startup, and shutdown.
Step-by-step explanation:

In a propeller system, an inspection should be performed before takeoff, after landing, or after engine shutdown.
This ensures that any potential issues or damage are identified and addressed before the aircraft is flown, minimizing the risk of accidents or malfunctions.
