Notes: Top 5 Mistakes Pilots Make (AOPA seminar Feb 21 2008)

83% of accidents are due to pilot-related factors

  • ‘inevitability’ mindset
    • “everyone is bound to have an accident eventually”
    • accidents are not inevitable.
    • fly the airplane and give yourself options
  • ‘get-there-itis’ causes obvious problems

AOPA resources

  • mountain flying
  • better way to escape imc

#1: Maneuvering flight (33% of total)

  • Pilots who put on impromptu airshows or barnstorm
    • reckless operation at low altitude
  • Traffic pattern
    • high power settings
    • low altitude
  • Low-altitude jobs like crop dusting, photography, pipeline patrol
  • It’s difficult to see obstacles at low altitudes
    • wire strikes involve 4 times more aircraft than helicopters
    • unlit towers – listen to notams!
  • Most stall/spin accidents occur on takeoff, not the base-to-final turn
    • high power setting and AoA
    • lots of rudder to offset turning tendencies
    • low altitude
    • attempts to return to runway

#2: Weather (14% of total)

  • Inadvertent IMC, often due to scud running, causes more than half of wx accidents
    • however, 43% of accidents involve IFR pilots.
    • 25% break up in flight, prior to impact!
  • First priority on encountering poor weather: LAND
  • On encountering IMC, use the autopilot to control the aircraft
    • 180° turn with heading bug!
    • at the least, wings level and full power!
  • Know limitations – yours, the aircraft’s, the equipment’s!
    • set personal minimums and do not break them
    • fly with a CFII in marginal weather to determine comfort level
  • DO NOT FLY IN:
    • thunderstorms!
    • ice!
    • heavy turbulence!
    • any weather below personal minumums!
  • If the weather is bad, there are two choices:
    1. Don’t take off! If you have,
    2. Land, anywhere that is available.
  • Consider teaching private students to fly a gps approach
    • downside: altitudes aren’t included in the hardware
    • plates can be confusing in sitting at a desk

#3: Takeoff & climbout

  • Highest workload and demand on aircraft occurs during takeoff
    • high AoA
    • low speed
    • high power
    • lots of rudder (to deal with latter)
  • Priority: keep it flying
    • use rudder for limited directional control
    • pitch for speed
    • stop the roll if not airborne
    • land straight ahead (on runway if distance remains) until at least 700 agl
  • Do runway length calculations
    • leading cause of takeoff accidents is a lack of performance
    • add 50% to distances – performance numbers are not gospel
    • if runway length <2,500 ft or altitude >2,500 MSL, figure for density altitude

#4: Descent & approach

  • Cancel IFR or close VFR flight plans on the ground at the destination
    • don’t blindly cancel when ATC asks you to report visual
  • Practice instrument approaches all the way to the runway
    • consider diverting if you go missed in actual
  • Practice crosswind landings
    • many accidents occur during the landing roll
  • Need more than 30° of bank in the traffic pattern? Go around!

#5: Fuel

  • 3 GA pilots a week run out of gas
  • plan to land with 1 hr of gas
  • if marginal weather, land or divert
