Ferris,
You are right from the info that I have. From the ATC perspective Civil Air has written to HREOC (I think) to reject CASA's application for exemption from E&D laws.
There could be as many as 60 controllers who would be unable to pass the vision requirements of the Class 3 medical come 1 May 2003. (One wonders what that would do to the rosters!)
Airservices is convinced it won't be that many and has backed CASA's decision; by the way the submissiion made by CASA in it's application is to 'bring it into line' with international standards; which can only be assumed is ICAO; which recommends the Farnsworth Lantern test in the event that a person can't pass the Ishihara Plate test. Go figure.
