No.... as said above... they do not have a high enough floor height. Don't hold me to this... I want to say it's 5 or 6 feet.
It's 6 feet, but it's measured differently for Type I and II
exits than for Type III (I don't know all the details). FWIW, the reason that CR7s and CR9s sit nose down on the ground (more so than CR2s) is so that the forward doors are within 6 feet of the ground.
146s/ARJs do as well.
