Not much.
From what I understand, none.
Last year when I was 7 hours short I asked Camielle Ence the same thing and she said sorry but it has to be actual or simulated instrument FLIGHT time.
I was very sad.
I just had a friend go out and buy 15 hours under the hood: not exactly cheap or pleasant, and argueably somewhat questionable, but the mins are time in an A/C only.
Sorry...
