1. Can a person with Dichromat - Deuternanopia become a pilot? This means that the person is moderatley severe and one of the basic mechanism is absent. In this case because it is Deutermanopia, it is the Green pigment which is absent/missing.
It all depends on how well they do on the tests, but generally I'd say it's no go. I have Deuteranopia and I was refused a Class 1 Medical.
2. Can a person be Dichromat - and at the same time be part Deuteranopia and part Deuteronomaly ?
I don't think so... it is my understanding that Deuteranopia means the absence of a cone that reacts to green wavelengths of light, while Deuteranomaly is just the impairment of that cone. I suppose it's possible to have say Deuteranopia and Propanomaly, but that would be bizarrely rare.
