Just a small posting to bring this to the top again.
Has anyone looked into whether there is any conflict with disability discrimination laws in their respective countries. With the work of Dr. Pape and the ambigousness (spelling?) of the JAA rulebook combined with the saftey record of CVD pilots?
I personally always fail the Isihara. I have tried the HW lantern at CAA LGW. They were very friendly but I found the test confusing especially after the 30-40th time of seeing the lights. A normal colour visioned person would have difficulty especially as they alter the hues. When in real life do they alter hues of Red/Green navigation lights?
