  2. 3. Human Factors - Definition <ul><li>The study of how pilot performance is influenced by such issues as cockpit design, temperature, altitude, the organs of the body, the effects of emotions, and interaction with other members of the aviation community, such as crew members or ATC. </li></ul>
  3. 4. Pilot Error <ul><li>An action or decision of the pilot that if not caught and corrected, could contribute to the occurrence of an accident or incident. </li></ul><ul><li>Inaction or Indecision </li></ul>

  5. 6. Accident Profile <ul><li>The pilot most likely to have an accident is between 50 – 100 hours, after receiving a pilot license. </li></ul><ul><li>Then at 200 hours when the pilot receives an instrument rating. </li></ul><ul><li>Next is the pilot between 100 – 500 hours, when confidence exceeds their ability level. </li></ul>
  6. 7. Basic Decision Making Process <ul><li>Gather Information </li></ul><ul><li>Process Information </li></ul><ul><li>Make Decisions </li></ul><ul><li>Act on Decisions </li></ul>

  10. 11. Process Information <ul><li>Several errors can occur while processing info: </li></ul><ul><ul><li>Attention may be applied too heavily to one item, while neglecting others. </li></ul></ul><ul><ul><li>Or making an error and not validating info by crosschecking. </li></ul></ul>
  11. 12. Decision Making <ul><li>Our decision making process is affected by such things as emotional state, stress, pressures, or specific conditions such as lack of oxygen. </li></ul>
  12. 13. Implementing Decisions <ul><li>Even if a pilot makes correct decisions, problems can occur that detract from the pilots ability to react, such as debilitating effects from fatigue, drugs or hypoxia. </li></ul>
  13. 14. Dealing with Human Factors <ul><li>AWARENESS: Aware of the affects of hypoxia, drugs and alcohol and how they may affect your decisions. </li></ul><ul><li>Awareness of how to get the most out of the aviation community. </li></ul>
  14. 15. Attitude <ul><li>A safety conscious attitude, always thinking of how safety comes to play. </li></ul>

  38. 39. Fatigue <ul><li>Often a contributing factor in aviation accidents. </li></ul><ul><li>Acute fatigue is caused by intense physical or mental activity over a short time. </li></ul><ul><li>Chronic fatigue results from many situations of acute fatigue, along with stress. </li></ul><ul><li>Both types diminish pilot performance, problem solving skills and lack of concentration. </li></ul>
  39. 40. Pilot Fatigue <ul><li>On the day of the accident, the pilot had been flying the aircraft at low level for most of the day, with minimal rest periods. He had only recently qualified for his private pilot licence and a significant portion of his total flying hours had been accumulated in the 9 days before the accident.

  43. 44. Anesthetics <ul><li>Local Anesthetics </li></ul><ul><ul><li>For minor operations such as dental work, flying is acceptable after 8 hours. </li></ul></ul>
  44. 45. Medications <ul><li>Generally, taking medication is an indication of not being well enough to fly. </li></ul><ul><li>An aviation medical examiner should be consulted regarding possible side effects and time to clear. </li></ul>
  45. 46. Medications 48 hours Sulfa Drugs 12 hours Barbituates 4 weeks Tranquilizer 30 hours Increased blood pressure Phenylpropanola-mine 30 hours Increased heart rate Anithistamine 15 hours Decongestant, stimulant Ephedrine 15 hours Pain Killer, may mask real problem Acetaminophen 2 hours Pain Killer, may mask real problem Aspirin Varies Stimulant, induces anxiety Caffeine Time To Clear Effects Chemical
  46. 47. Substance Abuse <ul><li>Over the past 10 years about 10% of fatal aviation accidents were related to alcohol. </li></ul><ul><li>Alcohol impairs memory, thinking, PDM, vision, hearing and coordination. </li></ul>

  51. 52. Hyperthermia / Heat Stroke <ul><li>In high temperatures heat stroke may occur as a result of the body not being able to dissipate heat through sweating. </li></ul><ul><li>Be prepared for hot/cold conditions. </li></ul>
  52. 53. Noise/ Vibration <ul><li>Exposure to noise or vibration for many hours may: </li></ul><ul><ul><li>Hamper crew communications </li></ul></ul><ul><ul><li>Cause hearing damage </li></ul></ul><ul><ul><li>Cause fatigue </li></ul></ul><ul><ul><li>Cause stress </li></ul></ul>
