Hi all,
This topic and the previous one re training, lead me to the
following question.
What is the accident/incident rate for low hour post solo pilots?
What is the acc/inc rate on breakdown form? ie number of hours flown
v number of accident/incidentss.
Anyone know this info?

When I first began work as a Sport Aviation Inspector at what is now
CASA, I did an extensive survey of gliding accident and incident
statistics, which was published in a special edition of what was then
the Aviation Safety Digest that was published to coincide with the
1987 World Gliding Championships.
I do not have a copy immediately to hand, but there are likely to be
a number of copies stashed away in gliding clubs and individuals'
collections of magazines. The particular issue was green and gold
with a photo of Harry Schneider's Platypus on the cover. All kinds
of statistics about phase of flight, length of flight since take-off,
total pilot experience, age and gender of pilot, were all recorded.
It is very unlikely that there have been any gross changes in the
distribution of accidents over the 20 years or so since I wrote the
article - though overall accident rates have decreased by almost
every possible means of measuring them. One significant change,
however, is that midair collisions have tended over the past 15 years
to be more likely to have a fatal outcome to at least one of the
parties involved, because of the increased energy involved in the
collision due to more efficient glider performance - so less energy
losses, higher speeds between thermals and more energy when pulling
up - so less chance to take avoiding action once the other party is sighted.
This, of course, is one of the major drivers of developing proximity
warning and prediction systems, e.g. Flarm.
Also, with increased emphasis on training and especially post-solo
and advanced training, low-hours pilots are likely to be better
trained (and training/checking better able to identify and rectify
training deficiencies).
