question.
Yes I believe you can overfly clouds BUT you should always be able to see the ground.
What it means is even though you'll fly over one cloud then you should be able see the ground beneath you in some way. Looking to your far left to see the ground or to your right etc..
*If you fly over clouds and cannot see any ground feature at all then you are illegal since you can no longer tell where you are. *
Flying over scattered fog for example, you fly over a cloud and still you are legal, why? Because you can see the ground through the holes.
The IR bit, I cannot believe that you could possible go IFR if you don't have an IR since the IR is there to enable an IFR.
You can file IFR in any type of weather since you might be wanting to fly very high (12000 feet over clouds etc.). But don't believe me on this one.
