Should the steering bypass valve be returned to normal after towing?

The steering bypass valve should indeed be returned to normal after towing. This is because the normal setting of the steering system allows for the proper functioning of the aircraft's steering and control systems during flight operations. When the bypass valve is set to bypass, it disengages the normal steering mechanism, which is essential for towing the aircraft but is not suitable for standard operation while airborne.

Once the towing procedure is completed, it is crucial to return the steering bypass valve to its normal position to ensure that the pilots have the necessary control authority over the aircraft during taxi, takeoff, and landing. Operating with the bypass valve engaged on an aircraft that is not being towed could lead to compromised steering capabilities, which can affect safety and handling. Thus, confirming that the bypass valve is returned to normal is an important step in pre-flight checks after towing.
