Are pilots required to notify the tower when they are flying "under the hood" for IFR training? I was reading a question about flying under the hood for Instrument Flight Rules (IFR) training when this question popped to mind.  Are pilots flying under the hood required to notify the tower?  Does it change the towers approach to that plane at all (especially in VMC conditions)?
No, because the responsibilities aren't any different. And, with a safety pilot on board, the capabilities really shouldn't be either.
