What is the function of the red guarded steering switch on the forward ramp panel?

• A. Disengages nosewheel steering and enables engagement of nosewheel steering
• B. Engages nosewheel steering
• C. Powers hydraulic system 2
• D. Switches the steering mode to automatic

Answer: (A)

This red guarded switch is a safety interlock for nosewheel steering used during ground operations. When you operate it, you deliberately disengage the nosewheel steering from the normal control path, preventing any steering input from being applied unintentionally during towing or maintenance. It’s designed so you can only disable or re-enable steering with a conscious, purposeful action, which is why the switch is guarded and colored red. Once disengaged, the system is in a state where nosewheel steering can be re-engaged through the appropriate controls when you’re ready. This function is specific to steering control and is not about powering hydraulic system two or switching to automatic mode.
