Automation Philosophy
Introduction
Automation is the replacement of the human function, either manipulative or
cognitive, with a machine function. The sole purpose of automation is to aid flight crew in doing their job.

Flight crew are the most complex, capable and flexible components of the air
transport system, and are best suited to determine the optimal use of resources in any given situation. They must be proficient in operating their aircraft in all levels of automation, and must have the skills needed to move from one level of automation to another.

Automation must be used at the level most appropriate to enhance the priorities of safety, passenger comfort, public relations, schedule and economy.

Use of Automation
The following guidelines will assist flight crew in determining and using the
appropriate level of automation:
• Programming actions and changes to automation status should be
verbalised and acknowledged.
• Flight crew should consider that all automated systems are dumb, dutiful,
and inflexible. Pilots must continually evaluate the automatics and what
they are doing. Be prepared to make changes.
• Timely and efficient use of the appropriate level of automation will allow
other matters requiring attention to be dealt with more effectively.
• Pilots should ensure that all operating crew members are aware of the
current status of automated systems as well as any changes made to their
use.
• Should a pilot feel uncomfortable with the level or use of automation,
either more information is necessary or something is wrong. The pilot in
this situation shall ask for additional information or propose an alternative
plan.
• Flight crew should plan ahead, using the low-workload periods of flight
effectively, and avoid programming during departures and arrivals.
• The programming of autoflight systems during high workload periods
may compromise the crew’s ability to maintain situational awareness
and/or flight path control. In these circumstances, the crew should be
prepared to use a more basic mode of automation.

• Automation occasionally fails. Periodically hand-fly the aircraft to
maintain basic flying skills.


• Use of automated systems can possibly create conflict. Communication
skills assume even greater importance under automation, where
traditional forms of feedback are reduced.
• Remember, when using any level of automation, pilots always have the
capability to:
• ask the other operating crew for help
• revert to a lower level
• disengage
• reactivate.
