During the operational test, what is the maximum duration permitted for the aerial stick?

• A. 180 seconds
• B. 150 seconds
• C. 110 seconds
• D. 120 seconds

Answer: (D)

The test uses a time limit to gauge how the aerial stick performs under a realistic, short-duration operation while ensuring safety and reliability. Setting the maximum duration at 120 seconds gives enough opportunity to extend, retract, and position the stick and verify control, responsiveness, and stability without allowing extended operation that could lead to overheating, excessive wear, or control drift. This two-minute window is a practical balance: long enough to complete typical maneuver sequences, but short enough to flag potential issues early. Longer times could mask intermittent problems, and shorter times might not capture the necessary behavior.
