From the final:
The CVR data indicate a change in the emotional state of the PIC on account of the aircraft adverse condition, to which he had to respond with an operational procedure that was different from the one for a normal flight situation.
The copilot, in turn, in his communications, gives the impression of being highly tense on account of the emergency situation.
This became clear with the delay of the copilot in retracting the landing gear, and in the PIC’s initiative to “feather” the propellers that had already been feathered by the copilot, after an order given by the very PIC.
The evident anxiety identified in the cockpit is reflected in the barriers and filters that influenced the process of communication between the two pilots, sensitively affecting the PIC’s situational awareness.
Moreover, it is a known fact that non-routine situations can cause a rise in one’s level of anxiety, but such alteration of the emotional state may be intensified when one does not have enough knowledge to manage the circumstance, and this interferes in the analysis of the scenario and adoption of appropriate measures.
