I've never been a fan of the S92 cabin from an evacuation point of view, but accept that it is a much more passenger friendly environment. Not quite as good as the S61 however!
The best suggestion so far was the one from SASless to go back to amphibious helicopters!
If we took the 61 airframe, added 92 Avionics, 53 running gear and engines....put in a plug to stretch her a few feet....would we have a winner?

Fit in the HMSD and Pilot sight unit of Tiger, ready is your perfect SAR Bird.
I am surprised SK did not try to put out a civilianized CH-53D with some modern technology and updated engines.
For that matter....why did the 101 never take hold in the civvies market?

Seeing there are "underwater emergency breathing apparatus"on sale why don't all passengers carry them.
First read about them on tuna boat flying and someone carried one with him in case he went for an unexpected swim.
Seems they are good for 30 breaths or a couple of minutes.

For A, they would have to re-certify the thing against FAR-29 (too expensive)
For B, most probably competing models were more apealing to the investors. Three donks suck a lot.

The S-92 "rig approach" goes around automatically if the pilot does not intervene to carry out a landing. The original concept was, if it all starts to go wrong, just let go and the aircraft will perform a GA at the pre determined pilot selected minimum. The original paper resulted from the BLUN accident in 2006. The final approach speed is GS predicated if I remember.

Apologies for not reading every post as this may have been asked already but has it been reported if any of the pax deployed rebreather and if it was effective or was the whole thing just to quick with there being no brace warning given, point raised is has the rebreather actually been used in anger ?? , personally I hated it on every foet I've done and found it so bloody diddly I'd likely take my chances without it

CH53D
SASLESS
Prior to the introduction of the Chinook on the North Sea, the idea of a civilian CH53 was mooted. Sikorsky apparently said that if 25 were ordered they would undertake the work necessary for civil certification. We never heard anything officially but Jock Cameron, BAH boss toured the worlds operators trying to drum up the orders but there were insufficient takers. I spoke to a Sikorsky rep in ABZ, late seventies, and he said that the CH53 was the best aircraft they had ever built. Shortly after the Chinook deal was done. Great aircraft, I flew it for three years.
For what thats all worth.

Heard a piece on iPM (Radio 4) about a pilot who had an encounter with a waterspout in a SuperPuma - G-TIGB. This happened in 2003, the helicopter returned to service and left for Oz in 2007.

SASLess - the main reason the CH-53 and the 101 haven't made it is cost & complexity. The -53 is a great helicopter but it hasn't even sold to many airforces.
There are issues about having to upgrade the helidecks on rigs etc and you'd need a much longer contract than is usual to make economic sense. Range rather carrying capacity would be the main attraction - if people get way out (say the southern end of S Falklands Basin) then they would be attractive - but if you are only drilling 3-4 wells.................

From Sunday Times
John Taylor, from Unite union, said workers were concerned about helicopter design. “They’re worried about seating, particularly at the rear where the windows are smaller. The concern is that the further back you are, the more difficult it can be to exit quickly.”
As we appear to be onto hypothetical helicopters now; for ultimate passenger safety, if a helicopter such as an S-64 Skycrane was used, and passengers travelled in a purpose-made detachable freefall lifeboat suspended underneath, then the hazards of passenger evacuation, risk of drowning/hypothermia, need for immersion suits/liferafts etc. would all be avoided.
Possibly not the most comfortable way to travel, but probably safer than trying to float a helicopter in the North Sea with the weight of engines, gearboxes and rotors above one's head.

G-TIGB ex G-BJXC S/N 2023 was the first Bristow 332L "Tiger" Its first client was Britoil and its regular run was the Thistle A using the Murchison as an alternate. It was one of the aircraft which had the short lived toilet on board, oh joy when that got used!
Now in Australia as VH BWJ with 36000+ hours and soon heading to the scrappy.

You've probably just come up with the safest offshore helicopter of all time. The "suspended" lifeboat could also have a parachute an fulfill the safety concern of someone earlier on who asked if there was a way to slow down helicopter descent in case of emergency!Probe to compare UK safety record in North Sea with other countries
Statistics uncovered by the Sunday Herald show Norwegian and UK offshore helicopters had similar fatality rates between the 1960s and 1990s. But in the last decade, the UK's record has worsened while Norway's has greatly improved.

I can remember too clearly some of the Helicopter Services S-61's winning Spindle Throwing contests.....was airborne in the Ekofisk when one of them happened....but that was in the mid-70's.
