Windows on the CEV will certainly be used for docking maneuvers. As such,
you need an unobstructed view forward, but that doesn't require a
particularly big window, nor many windows. Because their roles are similar,
what worked for the Apollo CSM will work for CEV as well.

There's a confident simplicity to simply looking out the window and
seeing your target, but it's not the only way to do it. You could
probably do better with radar far out and a closed circuit TV sighting
system concentric to the hatch close in.

Really it seems that docking is a problem with two potential solutions:
one is to use measuring schemes that can give you high precision
distances (and derivatives) and ultimately feed into an automatic
control system, the other is to train in a simulator to hand fly it.
Safety and tradition seem to dictate doing both. Composite methods are
possible - hand flying with input from instruments, TV camera, etc, but
then looking out the window fits with simple, low chance of system
failure philosophy of manual control.
