Pretty much do what everyone else said. Slow it down and focus on it more than you need to.
Your "blackout" or whatever is normal. Air awareness doesn't mean you visually know where you are in the air. It means you can feel where you are in the air. If you had like insanely excellent air awareness, you would be able to close your eyes and still know where you are in the air. It's something that you can't really teach. You naturally learn it. Seriously, the best thing you can do is the same trick over and over again.
To spot for a 3 I would recommend when you feel like you're at about 270 you look over your leading shoulder and look at the landing. There ya go, you spotted your landing.
Just do this over and over and over again. You'll get used to bringing your eyes around faster than your spin so you have that extra second to spot it. Then after a while you won't need as much time to spot it.
