splodge said it all! "The best thing we can teach students is when to say NO."
There is NO comparison between real-world helo flying and real-world airplane flying, because anyone who can spell "H" can make a heliport, while airplanes live in a world tailored for them. Every runway 27 is the same, everywhere on the planet, because airplanes insist that they be that way. There is no 747 pilot on earth who would take passengers to a rig, because all his alarm bells would be ringing as he landed.
Teaching everything to helo pilots is impossible, because we do everything, and every day is different. The most important thing we can teach people is when to say "Stop!" and "No!" which are functions of the limitations of the crew, machine and environment.
