Fits in with the 2035 period as they are common now. Would allow enhanced observation and allow the copilot to actually be useful by feeding contact information. Should have Day/night camera, NV camera, and black/white thermal.
This mod is close but I think it should be in vanilla:

it should also be visible by the pilot in free look as it could be useful for landing or if the copilot is down.
