Mars, all helo's are safe within their designed specs. Where all of these safety equipments part of their designed/Cat A specs at the time of certification? That is my question. Everytime we add something afterwards in the interest of safety are we not getting to the point where we are comprimising safety with all the extra safety equipment demanded and putting the original design under pressure? Take a 105. Certified plenty years ago, will it pass Cat A today with all these extra safety equipment regarding MAUW?
