Which result is expected when a catapult piston reaches end of stroke as detected by end-of-stroke switches?

Which result is expected when a catapult piston reaches end of stroke as detected by end-of-stroke switches?

• A. The system increases pressure to max
• B. The system logs a maintenance event only
• C. The control sequence safely terminates or transitions
• D. The piston reverses immediately with no change in control

Answer: (C)

End-of-stroke switches give the control system a definite confirmation that the piston has reached its physical limit. That signal tells the logic that the current motion phase is complete, so the control sequence should either stop that motion safely or transition to the next step in the cycle (such as initiating retraction, relieving pressure, or moving to a ready state). This keeps the system from pushing past the end limit and ensures a controlled, orderly progression of the launch sequence. It isn’t just about logging something, and it isn’t appropriate to keep applying pressure to the max or to reverse abruptly without a proper transition in the control logic.
