Greetings fellow earth dweller!
Sorry I should have specified... I am a CFII, and I occasionally will have students who need to do some air work on days when the weather is less than marginal VFR down towards the ground. My buddy would take his students and file then take them up above the deck and do his training flight up there and then shoot the ILS back into the main airport. I was pretty much confused as heck, as to exactly how he went about this. I didn't know if he got up on top where the vis was greater than 3SM and maintained 1,000 cloud clearance at all times, and did the training. I mean if the tops are at 3,000 this should be no problem. Then just picked up a clearance in the air and dropped back down and shot the ILS in...
