Bamma,

He/she is not talking about doing a drill, or as I called it "emergency practice".

I also don't think the person asking this question would be of the level you are speaking about concerning NDL with an AL80. Of course it can be done, without too much difficulty, but what we are talking about is hitting your NDL TWO TIMES with 1000PSI to spare. I can't figure it out, even with unreasonablly low SAC rates.
