Dear PCav,
I suggest you to learn more about JAR regulations, you can browse them in the
www.jaa.nl site, particularly focusing on JAR-FCL 3.225(a) and its appendixes.
You can learn that you can be tested with several other tests other than Ishihara and Holmes Wright lanterntest.
For example the least JAR discriminatory test is the Nagel Anomaloscope, or the Beyne Lanter test. You should find some clinic which can test you with those and determine if you are JAR compliant or not.
For example for the Nagel Anomaloscope the doctor should measure your matching range, and if that is within the four scale unit limit, you are considered JAR compliant.
Hope this helps,
Bye.
