Great news!
John Obrien and the CVDPA have won the case against CASA !
John, a severely colour deficient DASH 8 copilot (protanope) who has been unable to pass any of the colour vision testing in Australia has won his right to exercise his ATPL qualifications and fly left seat as Captain.
Although the 1989 Denison test case ruling decided that deuteranopes posed no risk to aviation safety - CASA still forced us to undergo colour vision testing. A lot of us, even severe deuteranopes, passed the tower light gun test as it uses true aviation colours and not wavelengths on colour confusions lines for CVDs (like Ishihara, farnsworth, CAD and all the others). For 25 years we've flown without accident or incident passing all check flights and sim rides.
Those that failed that were not allowed to progress beyond copilot of airliners.
John was one of these poor critters but has now proven to a court that even protanopes pose no risk to safety.
