Statistics
You cannot a avoid the statistics of the group to which you belong , but you can vary where you are on the probability curve.

"Most people use statistics like a drunk uses a streetlight! For support instead of illumination!"
Cheers! :-)

1947 general aviation accidents totaled 9253.
1990s general aviation accidents ranged from 1700 to 1900 per year.
Half of multi-pilots would not survive an actual engine failure on takeoff using their current emergency procedures.

Only 6% of the U.S. women are pilots.

Women pilots threaten some men's macho identity. Some men think that they are losing status by sharing the skies with mere women. I have found the women pilots I have taught to be better, over all, than the men.

Statistics as of Oct 2001
--If you are rushed for time you are eleven times more likely to make a mistake than if you have ample time.
--Safe travel by airline vs. car favors the car for short distances but beyond 200 miles airplanes are safer.
--The backswept wing reduces drag because it is aerodynamically a thinner wing.
--The air flow over a backswept wing causes the airflow to travel a greater distance.
--The thinner the wing can fly faster with the actual airflow slower over the wing.
--Vacuum failure causes average of two fatal accidents per year.
--NTSB recommends FAA treat all vacuum failures as emergencies.

--There are always times when a single engine failure has some potential for a serious problem
--Light singles have better safety record than single retractables or light twins.
--Half of mid-airs happen below 500 feet
--Mid-airs usually count only half of aircraft involved.

--75 percent occur below 3000 feet.
--75-percent of mid-airs occurred at combination of formation flying and uncontrolled airports.
--81 percent of 'incursions' are essentially non-events.
--Engine loses 3 percent of power for every 1000 feet of altitude
--In four year period ending with 2000 over 1300 incursions were reported with three minor accidents.
--By the age sixty you will need three times the light to see by as you did at 20.
--Average of 17 IFR aircraft fly into terrain every year. 50-percent of them at night.
--IFR controlled flight into terrain usually occurs on approach after radar service has been terminated.
--Visual illusions or disorientation cause 21 percent of IFR approach and landing accidents
--1975 ten percent of fatalities had alcohol as factor
--Late 1990s it was 7.3 percent
--Illegal drug use now runs at 5 percent
--DUI and DWI investigation program requires pilots disclose any actions when applying for medicals.
--Antidepressants are not permitted in airmen..
--Civil Aviation Security Compliance and Enforcement Branch must also be informed of DUI/DWI actions.
--A passenger on a commercial airplane could fly every day for 29,000 years before becoming a statistic.
--Facts have nothing to do with fears.
The chance of someone on the ground being injured in a general aviation accident is one is in 50 million.  Less than the chance of being hit by lightning.
--Less that 15% of general aviation accidents are from mechanical failure.
--Most general aviation incursions are not classed as serious and with little risk of causing an accident.
--Public use airports are closing at a rate of two a month.= 24 per year.
--There are more than 2000 current pilots over 80; 30 pilots are over 90; oldest is 99
--Based on this information I can expect to fly twenty more years....Gene at 79
---Slightly more than half of GA accidents are takeoff/landing related.
---SEL fixed gear aircraft have 37% of the landing accidents rare fatalities.
---2-3% of accidents were VFR into IFR but fatalities over 80% in these situations.
---VFR into IFR with complex aircraft have 90% fatality rate.
---Proportion of fuel related accidents still high
---2/3 of accidents during takeoff, maneuvers, landing
---Two-percent of VFR into IFR basis for total accidents.
---Weather accidents highest fatality probability
---Accidents not skill related as much as judgment related.

Stall Spin
-- Nearly 20 percent of Tomahawk accidents derive from the stall/spin;
--14 percent from PA-28 140
--10 percent from C-150 with the C-172 only slightly lower.
-- The C-182 and Piper Warrior are a fraction over 4 percent.
--1975 ten percent of fatalities had alcohol as factor
--Late 1990s it was 7.3 percent
--Illegal drug use now runs at 5 percent
--DUI and DWI investigation program requires pilots disclose any actions when applying for medical.
--Civil Aviation Security Compliance and Enforcement Branch must also be informed of DUI/DWI actions.

1998
--Greater use of autopsy gave more 'pilot incapacitation' as factor
--Half of engine failure fatal accidents were mechanical with 40% of them twins. (Skewing of statistics)
--Of retractables 43 percent of fatal accidents were twins.
--Homebuilts had more fatal accidents that all retractables.
--There is no basis for deciding the better engine between Lycoming and Continental.
--A turbo engine will last longer the lower it flies.
--Leaning is more likely to damage a turbo engine than a normally aspirated engine.
--Driving is seven times safer than flying.

2000 Statistics
Year 2000
Fatal accident rate was the lowest since recorded history began in 1938. According to the data, the fatal
accident rate at 1.11 accidents per 100,000 hours flown during 1982 made a 44-percent improvement over the 1982 of the 591 fatals compared with 341 in 2000.
--90-percent decrease in rate per 100,000 hours of flying since 1938
--Weather-judgment error accidents dropped nearly 50-percent from '98 to '99.
--18-percent of flying was flight instruction with only 5-percent of the fatalities.

10% of IFR accidents occur to non-IFR pilots.
VFR to IFR is the #1 pilot killer
Make one IFR approach and proceed to alternate for best risk reduction.

--The second most frequent cause of death for airline pilots before 60 is a G.A. accident
--Pilot population peaked at 827,000 in 1980 and is now down to 635,000 now but rising with nearly 6% women.
--Half of all accidents happen to pilots with less than 100 hours in type.
--More than half of mid-air accidents involve pilots with less than 100 hours in type.
--One in ten accidents of all causes happened to pilots with less than 50 hours in type.
--The average total time of pilots involved in icing accidents is over 3000 hours.
--Icing accidents of experienced pilots occur at airports and are usually survived.
--Icing accidents of inexperienced pilots are usually off-airport and fatal.
--Fatal accidents due to power situations result 15% of the time at night
--Fatal accidents due to power situations result 19% of the time in daylight
--25% of the dayling accidents were in homebuilts and warbirds.
--Twins were in a high percentage of the night accidents.
--If you have fuel and good maintenance, engine failure at night is a small risk.
