TelBoy,
Good points....
Something is already changing in FAA land, under inputs from the NTSB the FAA is reviewing and reevaluating colour vision testing, however they are talking about "grandfathering" all the already issued SODA (tower signal test).....
Do You think something similar will happen with the CAD and EASA?
I do not think they will retest people and may be cancel, until then valid, first class....
Ani inputs?
Later guys.
