A321 Landing Gear Question

Thu Dec 16, 2004 10:06 am

I was curious as to why the A321 doesn't have a tandem axel main gear like the 757. The MTOW of the A321 is 205,000lbs and the MTOW of the 757-200 is 255,000 lbs. Is the difference of 50,000 lbs the reason, or does the A321 have a stronger landing gear to support the extra weight on a single axil?

Any landing you can walk away from is a good landing! It's a bonus if you can fly the plane again!!

50k lbs is a good reason. Fewer wheels= fewer parts that can break down, have to be maintained, etc.

The B727-200Adv is even heavier than the A321 and still only has single axle landing gear.

A321's main wheel assy is appreciably larger than the 319's and 320's.

Anyone know why Indian airlines chose this option?

EDIT: I just realized this is an A320 and the question was regarding A321, but still somewhat relevant...

This is your captain speaking. I’ve turned off the no-smokin’ sign. Hell, if the plane is smokin' why can't you?

I read in a book that Indian Airlines chose the 4 wheel main bogies as a lot of the airports the 320 flies to don't have very strong pavement / apron areas.

The 4 wheel bogie spreads the weight over a greater area, making it less likely to break through the apron surface.

This probably is the most asked question on A.Net.

Do a search.You'll find a lot of Answers.

In the present senerio its not serving any purpose.Although at that time it was chosen for IA because of Not to perfect Runways in the country.
I may not win often, but I damn well never lose!!! ;)
