- Low-time pilots assigned to advanced technology aircraft may
not acquire manual flying skills, which are still required. (pc7)
- Pilots are reluctant to assume control from automation. When
automation may be malfunctioning, this could lead to unsafe
conditions. (pc26)
- Automation presents little or no feedback, or the feedback is
inappropriate or misleading. As a result, pilots may be unaware
of the mode (state) and behavior of the automation. (pc51)
- In some situations flight control is difficult after transition from
automated to manual flight. (pc55)
- Automation increases pilot workload at high workload times and
reduces pilot workload at low workload times, resulting in excess
workload and boredom. (pc79)
- Pilots accept or approve automation recommendations and
actions without critical, resulting in errors. (pc90)
- Automation design is not guided by a philosophy that gives
adequate attention to the proper role and function of the human
and to human capabilities and limitations. This compromises
system effectiveness and safety. (pc100)
- Pilots' understanding of automation is inadequate for the
performance of their duties. (pc105)
- Automation performs in ways that are unacceptable,
unexpected, and unexplainable by pilots, creating confusion,
increasing pilot workload to compensate, and sometimes
leading to unsafe conditions. (pc108)
- Training and checking requirements do not necessarily take into
account new flightdeck automation capabilities and, as some
pilots do not get the necessary training, they lack necessary
knowledge and skills. (pc113)
- Reliance on automation reduces pilots' awareness of the present
and projected state of the aircraft and its environment, resulting
in incorrect decisions and actions. (pc114)
- The fundamental reasons for the increasing use of automation
are to decrease the cost of flight operations. If these
considerations receive excessive emphasis in the aircraft design
process, safety may be compromised. (pc127)
- Pilots inadvertently select the wrong automation mode for
unknown reasons, causing the automation to behave in ways
different than intended or expected. (pc145)
