The whole thing looks like a legal mine field. What about the achohol & drug Co's? they will go broke over night !
Can they come into a crew room not on airside & test crew at random?
Some very valid points in these posts, I guess somebody will be "guinea pig" some time soon & be put under the spot light lets just hope they are wealthy & can show CASA what stupidity they have yet again dreamed up to justify their jobs!
A friend of my family's who has been involved in aviation since the Wright Bros! said probably 99% of people airside have in the past been under the influence of something sometime during their careers but I don't recall too many planes falling from the sky because of it. So from now on we can exepect perfect people doing their duties perfectly under this perfect system, yeah right, like to see that!
