Question 1040 Deck Safety

The correct answer is B) trick wheel. In an emergency, the electro-hydraulic steering units can be directly controlled by the trick wheel, which is a manual steering wheel that bypasses the normal steering system. This allows the operator to maintain steering control in the event of a failure in the primary steering system. The other options are incorrect because: A) the follow-up gear is part of the normal steering system, not an emergency backup; C) the rapson slide is a component of the steering gear, not a manual control; and D) the receiver unit is part of the electronic control system, not a manual backup.
