How can you verify that the rampers left the steering disconnect switch on the ground service panel in the down and guarded position?

• A. During the after-start check the Captain presses on the tiller; if the STEER OFF EICAS extinguishes, the rampers switch is down and guarded
• B. The STEER OFF EICAS display remains on continuously
• C. The Captain should cycle the switch twice and watch for a steady light
• D. A ground crew member must confirm with a hand signal

Answer: (A)

The test is about using the cockpit indication to confirm the steering-disconnect safety position on the ground panel. In the required configuration, the rampers have left the steering disconnect switch in the down and guarded position, which is verified through the after-start check. When you command steering by pressing on the tiller after engine start, the system should clear the STEER OFF indication on the EICAS. If the STEER OFF message goes out, it shows that the steering circuit is no longer in the off/disconnected state and the switch is indeed down and guarded, meaning the steering path is correctly enabled for normal ground handling operations.

This works because the STEER OFF EICAS indicator is tied to the state of the steering disconnect switch. If the switch were not in the down and guarded position, the STEER OFF indication would remain, alerting you that the steering disconnection protection isn’t engaged as required. The other options aren’t the standard in-flight verification: they either rely on a continuous warning that should not be present, involve unnecessary cycling of the switch, or depend on a ground crew signal rather than cockpit indicators.
