Answer to W8;
Re helmets, suits etc;
Gyroplane accidents broadly speaking fall into two categories;
1. Not survivable no matter what you are wearing.( loss of control at height).
2. Little or no injuries, again more or less regardless of protective gear. (Landing and takeoff accidents, rollovers, etc, which, while very spectacular,
wreck the machine but not the pilot.)
There is a third category emerging recently, of accidents in the initial climb,
due to inadequate climb speed, (poor training or poor understanding of the
power-required curve) where moderate injuries are likely.
In these accidents, protective gear is probably helpful, particularly helmets.
The first category is declining with the advent of pitch-stable machines.
The second seems fairly static.
The third has been to some degree recognised by the CAA, and hopefully
by the training organisations.
Being by nature a cautious person, I wear an inner layer of cotton clothing,
a four-point seat-belt, and a helmet.
I am sitting on the fuel-tank, after all.
Gyros are more complex than they look, but great fun.
