1-Circular cross section can resist Hoop's stress effectivelyas compared to other cross section.

2-Distribution of air is uniform.

3-Increases area of the fuselage.

Answer / lloyd

the elimination of corners ensures that the flow will not separate at moderate angles of attack

Answer / faiz ali

1.a circle has greatest cross sectional area per unit perimeter.
2.the fineness ratio,which is "length of fuselage/fuselage diameter",the drag for large fineness ratio is denominated by skin friction component which is relatively less.
3.low aerodynamic drag.
4.it resist the hoop's stess..

Answer / vijay. m

To maintain a constant pressure and temperature, without
any variation in the whole fuselage or ease of circulation
of constant pressure and temperature the fuselage is built
in circular cross section.

Answer / shikhar

the fuselage of the pressurized aircraft is made circular
because since fuselage is an aerofoil, it has a low pressure
area over the upper surface and high speed, and higher the
pressure at the lower surface. when the fluid flow through
an aerofoil. this creates a variance in temperature and
pressure inside the fuselage. So to minimize this effect
inside the fuselage, it is made of circular cross section.
