I hold the SODA for "defective color vision".
I'm a 747 Capt for an ACMI carrier.
Years ago I did need to complete a flight test with a Fed (at night) in order to "demonstrate" my "ability".
That was almost 30 years ago, but I cannot imagine it's changed much. This is the FAA we're talking about.
It was just a matter of pointing out various colors on charts, aircraft instrumentation and airport lighting.
The SODA has had zero effect on my "career", if you want to call it that.
