  • Experienced a hard landing?
  • ex‎ecuted a go-around after encountering brown-out or white-out conditions during the last portion of your approach to landing? *
  • Made a zero-visibility take-off in which you immediately lost visual contact with the ground while pulling pitch because of brown-out or white-out? *
  • Came close to hitting terrain or some other obstacle after inadvertently entering instrument meteorological conditions?
  • Narrowly avoided a wire-strike? *
  • Followed an instruction meant for another aircraft because of confusion over call signs?
  • Became so fatigued while flying that you had difficulty remaining alert and performing your duties? *
  • Were asked by a ranking passenger to perform an action that you believed was contrary to the safety of flight? *
  • Became so ill during a flight that you could not perform your duties?
  • Struck a large bird while in flight? *
  • Experienced much worse weather reroute or at your destination than was forecast? *
  • Made a significant navigation error that could have taken you into rising terrain‚ an enemy controlled area‚ or otherwise seriously jeopardized the aircraft/mission?
  • Experienced a failure of your night vision device during a critical phase of flight (for example‚ while on approach to an LZ or while maneuvering low-level)? *
  • Had a significant dispute with the other pilot regarding what course of action should be taken? *
  • Found that you and the other pilot had a very different mental picture of what was going on in or around the aircraft (for example‚ your position relative to friendly and enemy forces‚ the location of the next navigation fix)? *
  • Flown with a pilot‚ outside of a training situation‚ who did not seem to have the skills needed to fly the aircraft and accomplish your mission? *
  • Encountered turbulence so severe that you had significant difficulty maintaining control of the aircraft?
  • Discovered after a flight that some important part of the aircraft had been damaged without your being aware of it?
  • Had a weapon accidentally disch‎arge in your aircraft?
  • Had the other pilot perform some action that was completely unexpected and might have jeopardized the safety of your flight? *
  • Been forced to perform a go-around because of dust/brownout in the landing area?
  • Experienced a wire strike?
  • Had a radio communications failure that jeopardized the safety of your flight? *
  • Discovered during a flight that you did not have the correct frequencies and/or call signs required for communication with ground personnel? *
  • Lost communications with another member of the crew during some critical phase of flight? *
  • Realized afterward that you had followed the wrong procedure for an emergency or near emergency situation?
  • Discovered that neither you nor the other pilot had the controls?
  • Misinterpreted some statement or request by the other pilot or a crewmember leading to an unsafe condition? *
  • Exceeded the airspeed‚ power‚ or RPM limitations of your aircraft?
  • Had the other pilot misunderstand some statement or request that you made‚ leading to an unsafe condition? *
  • Noticed that the other pilot or a crewmember was doing something wrong‚ but did not correct them?
  • Experienced a lightning strike on the aircraft during flight?
  • Discovered during a flight that you did not have the correct maps for your route and/or destination?
  • Experienced a smoke or fire indicator that was not a false alarm?
  • Allowed a non-rated person to fly the aircraft?
  • Had a hard landing resulting in a maintenance inspection before flight could continue?
  • Taken off without checking the weather and/or NOTAMS?

  • Inadvertently moved the control (cyclic‚ collective‚ or control wheel) when you were not the pilot flying the aircraft? *
  • Had a flight control bind or stick?
  • Performed more than two unsuccessful approaches to landing at the same location during a single mission?
  • Performed unauthorized aerobatics‚ return to target maneuvers‚ or buzzed ground vehicles? *
