Yeah, I know ... been there, done that !

Back to the question of buffett margin. It has been awhile for me, but I thought that the CRJ-200 did have a very small envelope (20-30K) at 410. I know the first pic is of a 900, but someone claims the 200 margin is also 80K ?

I'm so old it could be blurred, but when I had initial training on the CRJ-200 in Montreal, the sim instructor made a lasting impression on me by climbing the sim to 410 and "demonstrating" the balancing on a pinhead design. Has my recollection of this event become blurred with age ?
