KPax,
Bit hard for a VFR flight to be visual with an IFR flight that is in cloud. However, provided the VFR flight remains outside cloud then the IFR flight who is inside that cloud is separated (segregated) from the VFR flight........if they are both in VMC then see and avoid applies in Class D with traffic info from ATC to help.
If you are using radar of course the info provided to you via SSR is always referenced to 1013.2 Thus provided that you decide to put QFE or QNH into the processor, you will get the appropriate readout to judge separation by regardless of what we set on our altimeter!!!
If we have an uncomfortable experience (safety) in any airspace we report the matter and then next time expect a more comfortable experience!

Lord Seven,
Please advise QTH as I would love to come and do a speechless, compass and gyro U/S flameout descent.....haven't done one in decades!!!
In class D separation is only provided between IFR-IFR-Special VFR. VFR flights are not separated from anything and nothing is separated from VFR!!!.........Basically, the only thing that the mil gain from having class D is that it removes the option from the VFR flight to corss without bothering to call which can happen in a MATZ.
