No not much happening.
Here's a few topics of interest:
1. A few aviation doctors I have talked to in UK
and Oz admit that during class 1 medical renewals
where the Ishihara cards are shown to
existing commercial pilots they will make
the odd mistake too - but they overlook it
because it is a demanding test and colour
normal people will make the odd mistake.
2. A UK perception scientist Dr Beau Lotto
admits that in some circumstances a
colour can appear as another colour. Search for
him on YouTube. It's very interesting.
3. An appeal court case is in progress in Australia. See CVDPA
