You were originally commenting on the two aircraft models, not the
seats. The CRJ has the same fuselage diameter as the Dash 8, so they
both take similar seats. The choice of the specific types of seats
and their spacing is up to the airlines.

Airlines have far less freedom in how they configure regional
aircraft. The seats can have different upholustering, and seat pitch,
but seat width is pretty much fixed by the manufacturer.

Yes, and with the same cabin width, the CRJ and the Dash 8 will have
about the same seat width. In fact, Contintental quotes the same width
in their seating charts.

Except for Comair, airlines using CRJ/Q400s don't have large enough
fleets to justify custom made seats that go through
approval/certification. Much easier to use the seats already certified
for that aircraft.

Yes, and there are at least two types that I can think of, one with
reclining seat backs, and one without.

The CRJ specs are 50 pax at 31" pitch in 13 rows. This uses 10.33m
with 2.01m taken up by door/etc. Door is 0.91m. Leaving 1.1m for the
rest.


The Q400 specs at 78 pax = unknown pitch.

Continental sets theirs up with 31/32 inch pitch - the same as their
CRJs.

Porter airlines has 70 seats at 34" seat pitch on its Q400s. 18 rows.
That takes up 15.69 metres of cabin length. That leaves 1.64m of
wasted space.

So we are back to the difference being the airlines, not the model of
aircraft. The original poster was commenting on the different models.
