what a load of blinkered nonsense all this colour discrimination is.
why is it that the accident safety investigators have never once thought to recommended changing the bloody colours!!!!
for
why white and red lights? why not white and magenta? yellow and blue?
aviation regulators must be some of the blindly stupidest people on the face of this earth.
"standards" - fix the actual problem.
after all it actually only involves changing the colour filters in front of the red lights.
T-vasis didnt need any colours.
it is perhaps just an accident of history but on our airfield if you were to name all the really good pilots among the 200 and something of us I guarantee you that most of the people named are colour blind in at least red green.
a more valid screening would be to knock out the lowest 30% of the population on intelligence. that after all would exclude all the cretins populating CASA.
