If KAAN was optionally unmanned I reckon certification process would go faster.Instead of designing it optionally manned i would rather go for an unmanned version by removing the cockpit and life support systems.
I asked this question because we need the usual processes to be faster however possible.
Also, even if it isn't optionally unmanned, I reckon it would be easy to make it so. I remember Temel Kotil saying that KAAN will be able to RTB on its own when the pilot lost consciousness.
