Flew a while ago, couldn't pass all the plates and doctors would use the Giles Archer Lantern and such like.
With old lanterns, greens look very clean (almost white) and whites dirty (almost beige); if I kept this in mind (and remained calm) I could pass no problem, obtained both class III & class II medicals.
Reckon I'm technically weak on green and white, tho' watching tennis/cricket matches or green & white lights is not a problem at all in real life.
Like to start flying again; but if I go to Gatwick for a Beynes and fail have I closed the door on myself or should I explore some other avenue first?
Such as going off to Germany/Europe/Australia?
