safe is not the equivalent of risk free

• If safe meant freedom from the possibility of
  harm, few human activities would meet the
  standard. In fact, the only way to eliminate risk
  from any activity is to avoid participating in
  it. While risk does not guarantee injury or make
  an activity unsafe, it should not be ignored. By
  analyzing mishaps, we can learn about potential
  risks and take proactive steps to control them.

Statistics Dont Lie

• While Riding the Subway
• 4.3 Million riders per day
• Average time on the train 22 min. one way
• That equals 4.3m x 22 x 2 / 60
• 189,200,000 lifetime minutes each day!

4

• I will live to be 100 years old.
• That is exactly
• 100 x 365 x 24 x 60
• 52,560,000 lifetime minutes

5
Natural Conclusion

• Get off the Subway FAST

Or I may be on of the 3.6 people spending their
entire lives in the subway today!

Statistics Dont lie

• Their interpretation may
• If they show a trend believe it!
• If they are inconclusive keep looking.

• GA facilities do not have all the resources ILS
  etc.
• Crop dusting banner towing have special risks
• More takeoffs and landings the highest risk
  flight
• Less resources on the ground dispatchers,
  mechanics, loadmasters, etc.

Weather Related

• While weather-related accidents dropped
• slightly in 1999, they continue to have the
  highest
• probability of fatalities.
• In single-engine fixed-gear airplanes, 65 percent
  (13 of 20) of weather-related accidents were
  fatal.
• In single-engine retractable-gear airplanes, 88.9
  percent (eight of nine) weather-related accidents
  were fatal
• In multiengine airplanes 85.7 percent (six of
  seven) of weather-related accidents resulted in
  fatal injuries.

Contributing Factors

• Weather
• 12.4 all fatal accidents
• Night
• 61.5 of fatal Instrument approach accidents

Will I ever Fly Again?

22
Absolutely

• The pilot-aircraft environment equation
• is the key to controlling risk. A capable
• pilot in a well maintained aircraft with
• proper consideration for flight conditions is
• one of the safer forms of transportation.
• Disregard any part of the equation and the
• risk will rise accordingly, as it does in any
• other performance activity.
