hi there,
Ok the facts on colour vision for a JAA class one medical, this may change when EASA becomes the new regulator.
The ishihara test, JAA standards for the plates, 24 plate edition, 15/15, Ishihara instruction pass recommendation 13/15..
The lantern tests are no longer accepted by AMC Gatwick, as the CAD test has replaced them,
The CAD test is only available at city univeristy and AMC Gatwick, if you fail the plates, you will need to pay another £120 for the CAD test, and you might need to test on a different day as they run the cad on specific days, that might be subject to change...
