I actually passed the Titmus test as well... The ishihara plates I have the same issue with... I'd be willing to bet that I can pass the 24 (or whatever the high number) plate version tho, because they allow you to get approx 1/2 of them wrong and consider that or better as a passing score... I mostly see the 9 or so plate verson tho, and not the longer test...
The titmus, I got 6 out of 8 right on the page that has the E's where you need to determine the direction that those E's are pointing. (He said even people with no color problems can't see those 2 plates most of the time either tho) The page with the number plates I couldn't pass tho. Not sure which one is the required one, because the FAA doesn't specify, but the AME said I would have passed. The thing that worries me is that the FAA says that it requires you to be able to get all plates with "No errors in the 6 plates" The page with the E's has 8 plates, so I'm not sure. I mean I could always take the long drive and use him as my AME, but what if he retires one day? Know what I mean?
Here's what the FAA says about the Titmus:
An applicant does not meet the color vision standard if testing reveals:
Any errors in the six plates of the Titmus Vision Tester, Titmus II Vision Tester, Titmus 2 Vision Tester, Titmus i400, OPTEC 2000 Vision Tester, OPTEC 900 Vision Tester, Keystone Orthoscope, or Keystone Telebinocular.
Now of course the Titmus they showed me 2 pages, and the one I remember passing has 8 plates, not 6...
Here's what they say about the Ishihara:
An applicant does not meet the color vision standard if testing reveals:
Six or more errors on plates 1-11 of the concise 14-plate edition of the Ishihara pseudoisochromatic plates. Seven or more errors on plates 1-15 of the 24-plate edition of Ishihara pseudoisochromatic plates. Nine or more errors on plates 1-21 of the 38-plate edition of Ishihara pseudoisochromatic plates.
I'm about borderline on the Ishihara. I really wish I only had to take the test once like in the days of old to get my LOE. The FAA screwed me on that one. Because I did take it before the change date... They sent me a letter saying that the FALANT was not accepted. (By "Mistake".) Then after arguing with them, they say OHH you are right, then they conveniently send me my corrected medical cert with a letter stating that they don't issue LOE's anymore unless you jump thru their hoops with the MFT/OCVT. Yet they still will accept old LOE's. Yea, this is about safety alright... Anyways, they basically jerked me off, because they knew the policy was changing...
