Which color vision test is preferred?

My memory was telling me that Farnsworth Lantern test was preferred to get
a waiver. Since that no longer seems possible, I'm looking for options
here. I read today that a Dvorine or AOC test is preferred. Can anyone
confirm that? Recommend another? Are these tests hard to find? What's
available in the Dallas? Obviously, I'd like to try to shop around some
of these tests without involving the FAA, before I have to use the light
gun test as a last resort.

I do suffer from a mild form of deuteranopia. Is there any statistics on
the number of pilots with this type of color blindness which have
successfully obtained their waiver/exemption? I remember reading, over a
year ago, some document from the FAA which gave some statistics, but I no
longer remember the break out.

Actually, my local EAA chapter has had an AME speak a couple of times over
the years, and I recall that this subject has been addresses locally be
others as well. Some years ago, a friend had the same problem and had to
obtain a Statement of Demonstrated Ability (SODA).

To the best of my knowledge, the FAA's interest in this matter is limited to
your ability to distinguish between the Red, Green, and White of the control
tower light gun signals--no other shades or combinations of those or any
other colors are of interest for this purpose. Good sources of reliable
information should include AOPA, EAA, your friendly local AME and the Safety
Program Managers from your local FSDO--who can be reached informally at any
of the semenars which they host. Of course, the easiest of all might be to
have a local tower controlled shine his light gun your way.

If you are in Southeast Florida, I can refer you to a source. Otherwise,
start with AOPA or EAA (depending on your membership) or look for the next
nearby seminar on http://www.faasafety.gov/SPANS/events.aspx


I hope this helps.
