Then in this example every plane that has poor rear views,has a gunner, and labeled '-bomber/attack' should be F3 capable?
Yes.
If I understand the reason for the existence of the F3 view, this argument is not valid.
As I understand it, F3 is available to simulate the SA available from the entire crew. Now, I am NOT in favor of giving any fighter F3 views, but logically, any aircraft with a crew on board should have the same capability. Where I think the simplified every-bomber-gets-F3 solution loses its applicability is on the planes with only 1 other crewman, i.e. the dorsal gunner. Why would a SBD have better SA than a 110, a Boulton Paul Defiant, or a Fokker G1 (if they got added)? They have the same, or in the case of the Fokker, more crew than a SBD, D3A, Il-2, etc etc.
Again, I'm not in favor of giving any fighter an F3 view, but I think something besides the generic F3 view should be applied to planes with only a dorsal gunner.
