Hey Commo,
I've just gone through this very recently, so here is my experience. I applied for AC Op, which is an air factor 4.
ECG - Hook up many sensors to get a very clear picture of your heart. They print off a couple samples of your heart beat, which is sent off to see if you have a normal heartbeat.
Blood Tests - They'll take about 5 or 6 viles of blood to test for a myriad of things.
Eye Test - You go through an extremely thorough eye exam, including eye drops which keep your pupils dialated for the purpose of testing your eye sight versus testing with no eye drops.
Just came home tonite and there was a msg from the MIR (as I am doing a component transfer) asking for my family doctor's fax number. Don't know what its about, but hopefully just to have them sign off on something minor.
I think thats it for AC Op, though who knows.

Good luck,
