Question 1047Deck Safety70% to pass
Dual electro-hydraulic steering units usually operate _______________.
AI Explanation
The correct answer is B) with one pump on standby.
In a dual electro-hydraulic steering system, the two hydraulic pumps are typically configured so that one pump is the primary unit, operating to provide steering, while the other pump is on standby. This redundant setup ensures that if the primary pump fails, the standby pump can immediately take over and maintain steering control. Having one pump on standby, rather than both pumps operating simultaneously, is the standard configuration to provide a backup in case of a pump failure.
The other answer choices are incorrect because: A) the follow-up gear is typically connected in a dual electro-hydraulic system, not disconnected; C) both pumps would not normally operate at the same time under normal conditions; and D) the system is not dependent on the rudder position being amidships.
