On the sides they stick out at the bottom for example.

I mean, for example, the side windows of a 737 are not rectangular. Are they to help the pilots see something?

I don't get it. Whay does a trapezoid window make it more aerodynamic?
2006-09-24 08:07:19 · update #2
I still don't get the aerodynamics part.

They are put in between the structural frames of the nose section.
If you look at the rivet lines, you see that they line up with the window pillars. You can see it in this picture:

The shape of the structural members is designed for aerodynamics as well as pilot visibility and is usually a compromise between the two since you cannot compromise strength.
The reason for them sticking out the bottom at the sides is for better ground visibility and to provide a big enough opening for an escape hatch. The front windows are shorter to compensate for the instrument panel.

The many windows give the pilots a wide field of view, but the windows also have to fit into the aircraft's aerodynamic shape and be very strong so they are resistant to damaged caused by bird strikes and the high pressures of cabin pressureization and wind. This is why there are several smaller windows instead of one large window.

Tis a result of aerodynamics, strength, vision. All three mixed gives the roughly similar shape of windows in most aircraft.

On the 'side' of the plane the windows are shaped to provide maximum strengh to the fuselage during pressurization, back in the 1950's a British manufactured plane (the Comet) was grounded after it was discovered that a high number of them had crashed due to high levels of fuselage stress from the corners of the square windows.
The Windows at the front of the plane are designed to minimize parasitic drag on the aircraft.

the tip of the plane must have a curved shape for aerodynamic efficiency, so the cockpit windows have strange shapes to make the whole thing behave like a curved window

It's for aerodynamics. It's also to help with stand the enormous pressures on the outside of the plane when it's in flight.

First thing comes to mind might be structural integrity and wind resistance? Then again, might be just for looks!

To give the pilot a better view with less distortion.

i'm a pilot and it's for aerodynamics and vision

I guess I'll go ahead and answer the same thing... one word, aerodynamics.
