rotorrookie took a few liberties with reality with that picture! The cabin has every window available as a push-out, and 4 big emergency exits in each corner, as well as a 6 foot ramp at the end. Those troop seats are removed with one hand pull, and are individually placed where the cew wants them, not mounted fully across the cabin in the SAR birds, so they are not a big deal. But when he shows one picture, it looks awful. Nice try.
Regarding the safety difference between civil and military stroking seats, the differences are small relative to the less safe non-stroking seats in grandfathered helos. Military stroking seats protect up to 20 g's, civil are 18 g's, and non--stroking are 4 to 6 g's (with no back protection at all).
The reason why hc must establish this seat mythology is that the stresses that an 18 to 20 g seat put on the airframe are so large that the floor structure simply cannot take swapping seats, and so the job of adding stroking seats is a lot more complicated and costly than just buying a seat. The floor redesign is eye-watering, about a 1200 pound penalty for the 225. Why? Because the 18 g's is about 4 times the load that the floor can take, so the seat won't stroke, it will simply tear a patch of floor off and merrily let the pilot bounce around the cockpit still strapped to the disconnected seat. Thus you get their chief salesman telling you that "you don't really need them" instead of a clear call for safety for passengers and crews!
This bizarro thread really scares me. When ppruners begin to debate if the earth is flat, and if we should take safety feaures out of new machines like the 139 and 92. It is the victory of rampant ignorance like this that makes me cynical about our plight - if pilots don't call for safety changes, don't expect regulators and manufacturers to line up to make changes.
If Luddite pilots like helicomparitor win their points, we will sit in pools of spilled fuel, unconscious in our seats waiting for the fire to reach us, while military pilots can walk away and help rescuers treat the passengers. Sad story, guys. Keep it up, weaken safety features, and close our market further, maki it better for our real customers, the passengers, to want another way to get to their destinations, and stop those checks from coming in!
