Not sure why I never thought of this before but it just entered my head this evening.
As most people know the typical angle of the fuselage of an airliner in cruise is anywhere from 1-4 degrees up depending on lots of things, but always slightly up.
Do "lie flat" business class seats actually have a couple degrees of forward slant in them when they are fully flat to compensate for the deck angle of the jet in cruise?
I know it is generally such a small angle that it wouldn't really be noticeable but then again, sometimes in the plane I fly if we're heavy, high, and flying slightly slower than usual due to a speed restriction, we can be up around 3 degrees and if I walk to the lav when it's like that, I notice it immediately.
Anyone know if this is considered?
