Without commenting one way or another on the judgement of the CFI, I rather doubt that any reasonably competent pilot, even with no time in the Cirrus, would have any trouble recovering from a 90 degree bank in VMC without a hood. The two critical items in the picture are altitude and airspeed; if you’ve got enough of the former and not too much of the latter, recovery is pretty straightforward (pull the power and level the wings and then start pulling.) At a 90 degree bank you will get a wicked descent rate, but the airspeed is going to take awhile to come up.
I’d interpret the “JFK” comment as a somewhat hamhanded way of letting you know what happens if you can’t recover from that attitude. But I wasn’t there; if the CFI seemed really rattled by the whole thing, then you probably don’t want to fly with that CFI.
One of the tough calls for any CFI is deciding how far to let you go to see if you’ll recover on your own, without killing you both. The further out you go, the more you learn. When I was working on my instrument rating, my Deeply Evil instructor (who I still work with) decided that I should go fly holds inside a relatively benign-looking California winter cumulus cloud (with 4000 feet of clear, warm air below.) The wing root seals on my 172 needed work, and so there were ice crystalsblowing through the cockpit and we were getting pretty hammered. At one point I got distracted while in the turn and then had the feeling that something was wrong–I heard the wind noise start to pick up and noticed that my bank was past 50 degrees and I was starting to lose altitude in a hurry. I did my unusual attitude recovery, swore at her, and she just cackled maniaclly as she usually does. Definitely got my heart beating, but I did do the right thing, a confidence point that gave me a boost.
