ocvt is an occupation colour vision test, basically its a real world ability test to discriminate colour tasks, like reading maps and pointing out different areas like airspace that have colour rings, victor and jet airways.. also telling the difference of shades, ie the hight of hills in mountain areas
mft is the practicle flying element, telling the difference on an airspeed indication, random colour based questions, colour of taxi ways lights, runway and so forth,
i think this type of testing is what we need in europe, because its fair..
