C Automation is now so reliable that the human input is no longer necessary D No over-ride facility is available on auto-flight selection as there are enough levels of redundancy to cope with any system failure. Explanation: This is allowing the machine to take over the total operation of the aircraft without monitoring or input from the crew. Question 916: What role should automation play with respect to flight safety? A Automation should be used as an aid to the pilot and not as an end in itself.
