Number 9....Nick is dead on the money on that one....he echoes my harrangue on that topic.
A large Arab oil company's part 91 operation ignored the reality of that concept....and bought 212's without SAS (.....SASLESS....to some!) and uses them for night offshore flights....defending their decision by saying...ah...but the weather is VMC. (despite no visible horizion). DF actually thought we believed that line I think?
