SM, that's true, BUT the operators fly the helicopters that the Oil companies fancy. see AW139, was never designed for offshore flying. and is crumbling under the unexpected pressure that continuous offshore exposure has given it. being in the industry.
one ,at times, gets the idea that the only reason companies choose a certain type. relates to the big boys toys syndrome. everyone else has this shiny new helicopter so it must be fantastic. when the opposite is often the case. version 1.0 snags. lack of spares = low availability.
back to the issue at hand, havent been so (un)fortunate to have a flight in a S92 but have been in the cockpit when avionics is on. and its unbelievable loud.
and if the Oil companies are so interested in safety. they would focus of the working environment of the people that fly them back and forth as well as the safety equipment of the helicopter.
noisy environment = fatigue = faults = accidents.
