Ok i have been reading the EASA medical book, now im confused as to the wording of this, as we all know caa shows first 15 plates, ie no errors, but under the EASA guidliness as the below says,
to pass the ishihara test, nothing about the first 15 plates no errors.. to me that says to the standard of the ishihara test 13/15, CAA get a grip and stop arsing about, make this a fair standard...
