JimL is right, but I use the same logic on this thread that I did when my young son asked me where the knives were kept. I asked him, "Why do you want to know?"
SASless, please understand that my questioning here has NOTHING to do with the performance of ANY aircraft. I am not the S-92, I am a person. I have opinions and ideas that I share here that do not infer ANYTHING about ANY helicopter. I believe the S-92 has the best OEI performance of any aircraft in its class.
I contend that we are channeled by our training from the first flight to think of engines as safety, and this creates an automatic response that hurts us.
More engines, More OEI performance, More safety. This builds in our minds the belief that no other investment in our machines will pay bigger benifits. Our regulators grow from our pilot pool, they are part of our self-hypnosis, so the safety rules grow from this same delusion.
I ask anyone to show the data to prove this wrong-
For twins that have basic OEI capability:
The safety of those aircraft will NOT be increased in any measurable way by adding full OEI performance. If we invest in full OEI performance, we will FAIL to make our aircraft safer, we will just make sure an aircraft with bigger engines crashes in the same way it now does, with all engines running happily while the real cause has been ignored.
