Scenario...

IFR aircraft was at 3000' direct to the IAF RNAV 36 approach, the aircraft was going straight in at the IAF and not to do the published holding pattern that the approach has. The crossing altitude for the IAF is AT OR ABOVE 2300.

The aircraft was just over an obstruction that was 3000....so once he is flying away from that obstruction you can descend the guy to 2300 and clear him for the approach.

Now...if the aircraft is still over the 3000' obstruction and you want to clear him for the approach, can you tell the aircraft to cross the IAF AT OR ABOVE 2300, cleared RNAV RWY 36 approach?

You didn't assign an altitude below the MVA because you said at or above...?!?

I'm guessing this is a gray area at best and probably better technique would be to tell the aircraft to cross the IAF at 3000 cleared RNAV.

Thoughts?
