A recent conversation with a PHI Captain confirmed no mention was made to the pilots re a reduced Vne for plastic wind screens.
That Captain also stated the real motivation for replacing the glass wind screens was not weight but rather costs. The Glass screens were prone to cracking if nicked by FOD kicked up by rotor wash.
Also a quick google visit shows a Red Tailed Hawk weighs from just below two pounds up to almost four pounds. That would on the order of almost twice the testing parameters used by Sikorsky.
Anyone care to calculate the impact force of four pounds at 140 knots?
Also heard is PHI is rapidly replacing plastic with glass for some reason.
One passenger's family has filed suit against PHI and I hear (rumour only at this point) one of the pilot's families have also filed suit against PHI.
