I agree, why on earth do not more manufacturers fit the BRS Chute, I assume cost to modify the airframe
Because its a waste of fuel with correctly trained pilots.
And also its a huge weight penalty for traffic load.
I wouldn't pay for it for either the fuel or the reduced traffic load.
If some talent limited pilots think its worth it crack on and fly with it but don't subject the rest of us to paying for that crap.
My personal risk assement for me is it doesn't reduce my risk to be worth it. In fact a bottle of diet coke on board would increase my flight safety more than a chute.
