What a great scheme this appears to be! Gutted I won't be able to apply as you would need to get an IAA Class 1 medical who don't have the CAD colour vision test.
Unfortunate for people like me who fail the Ishihara colour test and lantern test but can get a CAA Class 1 after passing the new(ish) CAD test at Gatwick!
May be worth bearing in mind for folks in a similar position.
