I feel I have to add my views on the comments flying around about colour
vision and flying.
CASA as it now is, years ago lost the fight to stop pilots with so
called colour perception issues from flying at night thanks to the court
action taken by Dr Pape. See www.aopa.com.au for his excellent paper on
the history of the so called colour vision standard and his fight for
fair play by CASA. The view of CASA up till then was that somehow it was
unsafe for pilots who failed the colour perception test to fly at night
but safe for them to fly around during the day or in thick cloud. You
could be flying through the thickest cloud imaginable during day time
but as soon as last light hit it was unsafe somehow? bizarre to say the
least
Maybe not as bizarre as you think, if you cannot see past the
windscreen, correct colour vision is hardly of much importance. On the
other hand, not being able to see if the plane beyond your windscreen is
coming or going just might. I have missed out on an Air Traffic control
job in the early seventies due to the red-green colour blindness. In
the end it was not the inability to read the colour charts, but rather
the inability to distinguish between pin sources of white, red and green
light. Whether or not such caution was justified is another issue.
Kind regards
Paul
