1. LOSING CONTROL of a Perfectly Good Airplane Janeen Kochan

2. Loss of Control  Why the topic?  The perfectly good airplane part  Who loses control?  Why do pilots lose control?  What is being done  What can be done?  Why not you?

3. Why the Topic?

4. Who Loses Control? (Commercial Jet Airplanes Worldwide1994-2003)

5. Who Loses Control? (General Aviation Accidents, 2000 - NTSB) RankOccurrence # Accidents 1Loss of Control In-Flight175 2In-Flight Collision with Terrain 88 3In-Flight Collision with Object 85 4Hard Landing 52 5Loss of Control on Ground/Water 47 (Collision with Object) 6Loss of Control on Ground/Water 46 (Encounter with Terrain/Water) 9Loss of Control on Ground/Water 39 10Loss of Control on Ground/Water 29 (nose over)

8. Who Loses Control?

11. What Can Happen?

12. Why Pilots Lose Control Unexpected Events and Surprise  Surprise due to unexpected event  Nature of surprise  Insidious  Subtle  Cues most often available  Not necessarily highly unusual or novel  The process of surprise

13. Why Pilots Lose Control Unexpected Events and Surprise  Expectations inconsistent with ongoing situation  Lack of cues and/or improper interpretation of cues  Erroneous probability estimations  Decision making becomes impaired and/or delayed  Focus on event leads to an interruption of ongoing activities  Interruption of ongoing activities can lead to…

14. Why Pilots Lose Control Aircraft Upsets Unintentional:  Aircraft pitch greater than 25 o nose up  Aircraft pitch greater than 10 o nose down  Aircraft bank angle greater than 45 o  Airspeeds inappropriate for the conditions of flight To include: Any other aircraft state that is not intended by the pilot

15. What is Being Done Formal Requirements - Practical Test Standards  Recovery from unusual flight attitudes  Exhibits knowledge of the elements related to attitude instrument flying during unusual attitudes  Recognizes unusual flight attitudes solely by reference to instruments; recovers promptly to a stabilized level flight attitude  Using proper instrument cross-check and interpretation and smooth, coordinated control application in the correct sequence

16. What is Being Done Formal Recommendations  FITS (FAA/Industry Training Standard) – for technically advanced piston or light jet aircraft  NBAA Training Guidelines for Single Pilot Operations of Very Light Jets and Technically Advanced Aircraft  Industry Airplane Upset Training Aid, Rev. 1 – training curriculum for air carrier operations

17. What Can Be Done?  Awareness  Training  Academics  In-Flight  Simulator  Practice to maintain basic flying skills  Advanced airmanship attitude  ‘Aeronautical sportsmanship’ David Robson – “Skydancing; Aerobatic Flight Techniques”
