Whats the source of that drawing? Does the author have a history of credibility?
Whaat are two thin lines in the middle of the big cabin window?
Also, does the small round window suggest cabin has been lenghtened compared to uh60 after all? If so, itd be no small feat, probably indicating quite a diffferent solution gearbox wise and tail rotor shaft wise.
thanks! having that in mind, it seems z20 may follow general seating layout of uh60 family. though, the small circular window suggest a bit of extra space at the back. but, unless there's even more space available in the back, behind the window, i can't really find a way to utilize that extra cabin room for a meaningful number of extra seats. perhaps wisest way to utilize such extra space would be just extra floor room, for carrying a wounded soldier or something like that.
