S76 OGE OEI perf
Looking at the lists of perfomance charts on the RFM (Section IV on both Part 1 and Part 2), there is no such data. You only will find charts for Hover Out of Ground Effect at Take Off Power AEO and Forward Climb Performance OEI (Sec IV, Part 1) and Hover Out of Ground Effect Endurance AEO (Sec IV, Part 2).
Sometimes military manuals have more specific performance data, but I have never heard about a military S-76. Glad to be corrected (and informed about engines and specs) if wrong.

They operated the S76 in the SAR role in Hong Kong years ago. They then moved on to the AS 332L which gave you a chance at +30C over the water.
I operated the S76+ there for a time and it was enough trouble hovering with both going let alone one.

Both dogs, and as SAR machines heavy dogs. We got a “good deal” on an ex-HK C+, then hopelessly tried to get it light enough to give customers some payload. Was always the first machine released. OEI HOGE was a new performance requirement for commercial SAR that had to comply with rules meant for passenger transport. Even with the (relatively) mighty AW139 we couldn’t train SAR in peak heat summer months (over 35C) because we’d be over the OEI HOGE weight of 5200 kg.

It is also what I'm thinking, so I'll try to find "the right people" at Sikorsky and ask about.

No, they were actually "A++" versions. The C's (or "B-" as they were sometimes scathingly called) were not SAR equipped.
The old SkyShuttle C+'s didn't go to GFS....GFS had converted A-models with Arriel engines (the tail is a give-away it was once an A, the engine cowl is a give-away it has an Arriel). They also might have had a C for a while, but I'm reasonably sure they never operated a C+.
