Yup, like the man said, the AH64A doesn't have a radar or MFDs, the AH64D does.
If ED goes through with this I think they should model the AH64A and the Ka50N.
The AH64A:
Doesn't have either an A2G radar nor MFDs, so there would be no issue with their modeling.
The Ka50n has a FLIR just like the Ah64A
And it doesn't have any MFDs either, just an HDD for the FLIR.
I think it would be a fair match-up.
Modeling the AH64D and the Ka52 would intail modeling A2G radars as well as MFDs. I know that the Ah64A has two crew, so you'd think the Ka52 as a match-up, but the Ka52 has really crappy pilot visibility, but more importantly, it has A2G radar and four MFDs, so it is far more capable than the Ah64A.
Just my 2c
