It amazes me that CASA are being so regressive. Colour vision restrictions were regulated way back in the 40's and 50's when they actually had some context. With the technological advances of today I can't think of a single application that is affected by colour vision. My bet is CASA will be playing the international standards card.
I am happy to make a donation to this fight but I agree with Frank, I doubt that the Pilot fraternity as a whole will raise the required funds. Surely there are CVD Pilots out there who are members of the AFAP or other unions. If so, and their jobs are threatened by this (as they will be), then the their union must have an obligation to protect them.
The AFAP in fact offer substantial Loss of License insurance to their members. My guess is they would have a financial interest in this as well as an obligation.
