Last summer I failed the Isahara plate test, and got the dreaded night flying restrictions put on my 3rd class medical. Im in the process of trying to get it cleared up, so I gave Aopa medical services a call. The lady made it sound like the Farnsworth is on the way out, and to try and find someone who uses the Dvorine test. Anybody have any luck with with this test, how is it compared to the Isahara? I'm located in Northeastern Ohio if anybody can point me in the right direction.
