Hard to answer that as most don't say anything about their runs. Mine was
always in drag racing and in front engine cars. We lile others had oil downs
and flash fires and reaching for a chute release could have been a problem.
Being in aerospace hydraulics it was easy for me to have information and being
able to build my own stuff. I also try to learn from the other guys
experience. Back then the strips were short in the stopping area and we drove
into the chute by pulling it as we entered the traps.
I used the same system at the lakes and drove into the chute by habit. It
always worked for me. Others like to decell first and pull the chute . it's a
matter of choice. I think it has saved a lot of cars and would have saved
others from spinning.
The main thing is knowing where the release is and not having to look for it.
It has to be something that is normal each run. I know others that don't use
their chutes at the lakes and bonneville as they have a lot more room to stop.
I just liked the security of using it first and the brakes second.

Based on your experience, what percentage of mishaps have occurred right at
the final timing line where reaching for the chute release may have played a
part in the mishap?

I tried an electric pull solenoid before I made my air operated system.
The
problem I found with the electric was the short pull. With air I could get
a longer stroke to assure the release cable pulled free of the chute flap
loop. I used a Clippard small bore cyl and air switch and a 1 qt. storage
bottle. As I recall the stroke was 2 to 3 inches. Air pressuer was about
50
psi. I also could over ride the cylinder as the cyl was inside a tube and
would slide manually in case the air system didn't work. However it asways
worked.
Nice part abo! ut it is you can keep your hands on the wheel and not reach
for
the release like most do.
