PKIERZKOWSKI_070328_FGZCP_CDG Air France Flight 447 (Event Sequence (Plane…

- - - - Inconsistent to the level of experience
  - - - All at a risk
  - - - Tripped the plane out of autopilot
      - Sever environmental constraints outside of specified and certification parameter (BEA 2009)
    - - Technical factors
        
        Pilots received false readings lead to their confusion of the stall (BEA 2009)
  - - - Experience
- - - - They captain's choice of putting the least experienced pilot in charge
        
        Allowed for a series of inappropriate actions performed by their less experienced decision making skills within the situation (BEA 2009)
      - Stall alarm was ignored
    - - Reliance on autopilot
- - - - Passengers
    - - Proper material used for the aircraft to stay in the air
  - - - Airspeed
      - Radio communications
      - Altitude readings
      - Computer system
      - Autopilot
        
        Dependant on pitot sensors function
    - - Engine
    - - Pilot sleep cabin secluded
    - - Required to lift off and flight a large number of passengers
      - Able to withstand normal weather conditions
        
        Storm made it difficult for the aircraft to navigate in severe weather conditions (BEA 2009)
  - - - Worn down pitot
  - - - Pitot
  - - - Withstand design lifecycle
      - Usability of systems
      - People
- - - - Cumulonimbus clusters formed
      - Significant electrical activity at the flight level
        
        Effects computer readings
        
        Pilots chose to believe the incorrect computer readings hence ignored the alarms that signalled there was a stall according (BEA 2009)
      - St elmo's fire releases heavily charged ice pallets
      - Electrical disturbances and unusual smells in the cockpit
- - - - Crews confusion led to the failure of diagnosing the stall situation for the correct action to be made
    - - Lack of communication
        
        De-structuring of crew cooperation
  - - - Did not communicate appropriate action to recover from the stall until it was too late
        
        Did not immediate return from his break when he was called
        
        Confusion obstructed his ability to comprehend the aircraft readings and situation in time
        
        Lee (2007) describes the human- machine relationship as one that is complex and requires adequate management
      - Chose to put the least experience co- pilot in charge of the plane
      - The captain decided to keep Flight 447 on it's original course through oncoming cumulonimbus thunderstorm clouds instead of diverting around
    - - Failed to take the place of his least experienced co- pilot Bonin
      - Could not comprehend the situation and help recover from the stall
        
        Allowed for Bonin to ascend the plane which was consequently the worst course of action
    - - Incomprehension of the situation when the autopilot disconnection occurred and he had to take over manual control
        
        False reading from the frozen pitot lead him to apply the wrong action
        
        Tries to ascend pulling the control stick back causing the plane to lose speed
        
        Believes the speed is too fast hence presses down on the break
        
        Scharre (2015) states factors that affect the dimensions of autonomy and the information inputs that are necessary to achieve the desired function is heavily relied on in human - machine relationships
      - Emotional factor in his decision making
