Subject: [Aus-soaring] Coping strategies
for colour blindness
Stuart (and others who might be interested).
I
guess the "coping strategies" used by we "colour blind" people use
depend
on the degree of colour blindness. I can only speak from my own
experiences.
I don't recall the exact name of my "affliction", but mine
is realtively
mild. Red and green are the usual problem colours. I have
problems generally
with the finer shades of red and green. I actually had
no idea I had a
problem until about 2nd of 3rd year high school when a guy
came around doing
vocational guidance testing and I had all sorts of
problems with the
"Ishahara (?)Test" - the book where the pages have
numbers made up of
coloured dots. It was then I realised why I sometimes
said something was
light green when it was light grey, or dark brown
instead of dark red. I do,
though, still see most variations of red and
green as somthing that I
identify as red and green, but clearly I don't see
it the same as you
"normal" people do, either as colour or as
intensity.
If you are wearing a red or green shirt I know you are. And
I love red cars.
I see red or green traffic signals - if you turned the
lamp set upside down
I would know it so I don't go by the "top" and
"bottom" light to decide if I
go through the intersection!
In the
garden I'll see a red rose but I have to look for it - it doesn't
jump out
at me the way a yellow or white one does.
In terms of coping
strategies, the conscious ones at least are pretty
simple. If I play golf I
will never use a red tee because it will be a
"single use" job! I'll never
find it again - so I use yellow or white.
If I'm choosing clothes
or anything to do with colours (and I hate shopping
with a passion) I seek
the advice of my very colour wise wife.
The biggest major coping
strategy though was to have to forget my lifelong
ambition to be an airline
pilot. The first strategy then was a change of
career and I became a civil
engineer. When my first posting with the (then)
DMR in NSW took me to
Wentworth, and the resident works engineer turned out
to the president of
the Sunraysia Gliding Club, the second major strategy
was to take him up on
his invitation to go gliding, so flying became my
recreation. And, in one
of those life-numbers that you don't want to work on
too often, I see from
my logbook that on 18th December it will be 40 years
since that day that
changed my life for the better!
Other than that, it's not something I
really think about, nor am overtly
conscious of most of the time. As I sit
here looking out my window across
the lovely green garden into the clear
blue sky it all looks great -
whatever colour it really is!

Mark,
Back in the 60's and 70's you could get a CPL while colour blind, you
just
could not hold any form of instrument rating including the Class 4,
now
known as the NVFR rating. Then some time in the 70's or early 80's they
made
it a requirement of a CPL to hold a Class 4 instrument rating. However
you
could not hold a CPL or higher if you had any form of vision
correction
until 1977 or 1978.
Not being colour blind I do not
understand the coping strategies colour
blind people must be using every
day - however back in the late 70's I was
doing a night arrival into Perth
and I had a friend with me board who was
one of these colour blind CPL
holders - there were some red displaced
threshold warning lights (in those
days both ends of the runways were lit
green) and this did cause him some
problems understanding what he was
seeing. One example I know, and not
scientifically based, but I felt worth
sharing.
As far as FLARM is
concerned (I have not used one yet) aren't the green
displays the outer
circle and the red the inner circle? That alone would
resolve the
colour issue, along with variable tones.
SDF
PS - have you ever
considered how hard it would be for the audio impaired to
become involved
in gliding?

Subject: RE:
[Aus-soaring] FLARM @ KEEPIT
I feel I have to add my views on the
comments
flying around about colour vision and flying.
I am a glider
pilot and a light aircraft pilot
and I also fail miserably any colour
vision
perception test (and I was a guinea pig for the
University of NSW
over this enduring many of
their weird tests in the name of science) and
yes
its a red/green issue however I have never ever
had a problem with
colour perception whilst
flying over many years. Nor has any
instructor
ever commented that I had a problem. In practice
none of the
"experts" in this area have ever been
able to show that a pilot with a
colour
perception issue was somehow unsafe or incapable
of flying an
aircraft in day or night conditions
to the same level of safety as colour
"normal" pilots.
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 and with no scientific
evidence to support their case which is why
CASA
lost. Dr Pape in his extensive research could
find no evidence
anywhere of any
accident/incident being attributed to colour
perception
issues and this was not refuted by CASA.
The only restriction imposed
by CASA now is you
cannot gain an APTL (airline licence) and this
is
more to do with international bodies not agreeing
on the standard
that should apply then any
problem with flying for the airlines. Pilots
with
colour perception issues can fly around at night,
in the thickest
cloud etc all in a standard
aircraft without CASA or anyone else imposing
any
restrictions or requiring "modified" instruments.
Ironically now
of course modern light aircraft
are making ever increasing use of
colour
instrumentation, GPS etc and complete glass
instrumentation is
becoming more common. No
manufacturer that I know of feels they have
to
make special versions available for pilots who
fail standard colour
vision tests or issue
warnings or limit some pilots from flying
these
aircraft. You can get a Cessna 172 now with full
glass
instrumentation just like the airlines fly!
I fly a GPS equipped C182 and
its colourful
screen is a joy to use not a problem for me.
To the
point finally for those who have read
through this, if there any problems
with the
readability of the displays on the FLARM it will
apply to all
pilots not just the ones with a colour perception issue.
And lastly its
such a pity so many pilots my age
were stopped from pursing an aviation
career in
the seventies and earlier because of the misguided actions of
CASA in the
past.
