You guys are certainly talking the talk. I'm liking what I hear. Yes I agree there probably is a point at which a colour defective becomes unsafe to pilot an aircraft. However I think the time has come to give the current testing methods and standards a complete review.
As I said before I failed both the plates and the Farnsworth. CASA have designed a "last chance lantern test" which can be sat at the Melbourne university of optometry. I sat this and passed. I had no idea I had passed until they told me as it seemed no different to the Farnsworth. The difference was of course that it only tested red and green as these ar the only colours having significance to an aircraft in flight.
I will try and find out where this test is at these days as it was around 5 years ago when I gave it a try. I'll get back but it may be a while. In the mean time you should seriously try and get hold of Pape. I guess the standard is not really cr@p just not relevent in its current form. <img src="cool.gif" border="0">
