Hello guys.
I have a question about the FAA CVD standards.
Ishihara pseudoisochromatic plates: Concise 14-plate edition: six or more errors on plates 1-11; the 24-plate edition: seven or more errors on plates 1-15; the 38-plate edition: nine or more errors on plates 1-21.
Do they really follow those procedures? Will I be considered color vision safe if I fail 5 plates(official 14 plates test) or the doctor can disqualify me even with this score ?
I'm asking this question because I read cases of pilots in the US that weren't tested with the official Ishihara plates but with a shorter version with just 8 or 9 plates and no errors were allowed.
