Say I know someone who is about to start instrument training who I want to split plane time with. For both of us to get pic time one of us needs to be under the hood. Is he allowed to wear the hood and log simulated instrument even though he's not instrument rated? I ask because I don't think he'd want to split time if i'm always the one flying under the hood. He'd get the time but he would be bored out of his mind. Also, the answer is probably no but if the plane is not legal ifr can one of us still go under the hood and log the time for things like level flight, turns, etc? I obviously wouldn't file ifr or shoot an approach but I thought i'd ask.
