Chapter 10: Aeronautical Decision-Making and Judgment  Figure 10-2.  The five hazardous attitudes identified through past and contemporary study. During each flight, the single pilot makes many decisions under hazardous conditions. To fly safely,  the pilot needs to assess the degree of risk and determine the best course of action to mitigate the  risk. For the single pilot, assessing risk is not as simple as it sounds. For example, the pilot acts as his or  her own quality control in making decisions. If a fatigued pilot who has flown 16 hours is asked if  he or she is too tired to continue flying, the answer may be “no.” Most pilots are goal oriented  and when asked to accept a flight, there is a tendency to deny personal limitations while adding  weight to issues not germane to the mission. For example, pilots of helicopter emergency  services (EMS) have been known (more than other groups) to make flight decisions that add  significant weight to the patient’s welfare. These pilots add weight to intangible factors (the  patient in this case) and fail to appropriately quantify actual hazards, such as fatigue or weather,  when making flight decisions. The single pilot who has no other crew member for consultation  must wrestle with the intangible factors that draw one into a hazardous position. Therefore, he  or she has a greater vulnerability than a full crew. Risk  Assessing Risk Remote Pilot – Small Unmanned Aircraft Systems Study Guide  54
