Is it true that the A318 stands higher than the A319/20/21s.If so why.

A320- 11.76 m
A321- 11.76 m
It is only about 1m, so Im not too sure why

Hope this helps,

Taller vert stab. Needs to be bigger to allow for engine out stability. Since the fues is shorter, the vert stab is clsoer to the engines and has a shorter arm.

(see also 737-600)



When in doubt, one B pump off

... and A330-200, I'm trying to think of other shrinks that have this feature, but thats all I'm getting. Pretty sure L-1011-500, 735, And A340-200 all kept their original tails. Any other shrinks I'm missing?

737-600 has a bigger vert. stab, too. The 737-600 looks like a football with wings  airplane

Ah! the SP. THe dimesnions don't do it justice. Becuase the fues slopes down rather strangely, you get much more than surface area than those 2 feet of height would suggest.

It is only about 1m, so Im not too sure why

So the difference in height is mainly by the taller Vertical stablizer.Is the MLG height the same for the entire family.

I would guess that it is the same since the wing is the same and it would be a lot of trouble to change the gear for one version, especially a niche version.

Usually shorter aircrafts have to have larger vertical stabilizers. The 318 is higher than the 319/320/321. The 737-600 is higher than the -700/800/900. The 747SP is higher than the -100/200/300/400. The 380 has is also quite high in comparison to its length (the -900 will probably have a smaller rudder). I think this has to do with the leverage.

HAWK21M, Doug_Or,

The 321 wing has in fact a deeper chord than the 320, giving it a marginally bigger wing area.
The interesting bit is that the increased wing surface is not for heavier weight reasons (as Doug said,that is taken care of by the new, more lift producing flap system ) but for handling reasons i.e. the risk of tail strike on takeoff rotation.

Regards

As Doug_Or and Pihero point out, the wing is basically the same, so same span. - - Slightly deeper chord (didn't know about that!)
- Addition of double slotted flaps allows for the same low speed performance.

Exactly. The torque is proportional to the length of the lever and the size of the force. Larger rudder=larger force to compensate for the shorter lever. Of course, the plane does get heavier with length, which explains why the 340-500/600 has the larger fin/rudder from the 330 despite being longer.
