Flugpants
There has been extensive discussions on colour deffects and the poss.of obtaining a Dutch class one.If you go back over the past 6 to 9 months on this forum you will find it.From what I recall the Holmes Wright is the same but nearer which helps.I also recall that the medical is valid over here but the CAA are informed of results.
Anyway,check back.The info.could even be on this thread.
Good Luck
