I am a protanope defective. Back in the mid 90's I did a modified lantern test at the Vic school of optometry after being refered to them by the CASA, this test is still available. To my surprise I passed and as such was issued an unrestricted class one and an ATPL. AP sure made a big difference and I plan on providing support for the cause going forward. Anyway I couldn't find in your posts that you have done that modified lantern test. If you havent I would certainly recommend you give it a go.
