have 4 instead of 2 weels on the main landing gear?
is it because of higher MTOW, i know for sure that this is the only one in the world like this.

This question pops up fairly regularly here. IC is unique in having ordered A320s with 4-wheel landing gear. It was done to handle landing on rough fields in India.

I don't think all their A320s have it, and I understand they are not going to buy any more like that. I think the standard 2-wheel gear has proven to be good enough to cope.

A thread discussing this is at Indian Airlines A320's Main Gear Have 4 Tires (by United777 Apr 25 2003 in Tech Ops) , with multiple other threads linked from there.

Basically, it lowers the pavement loading for use on runways that would otherwise not stand up to repeated A320 landings.

Thats interesting. I never knew there had been a handful made with that landing gear config. Thanks for the link to the other thread.

And had the bogie version is better marketed, Airbus would have made a few more sales in some parts of the world (where PCN is a HUGE problem)...

I'm surprised that the only version ever fitted with this option was the A320 rather than the heavier A321. What's the wheel load of an A321 compared to a 777?

And were large modifications needed to the wheel bay?

Higher of course, but nowhere near the 727-200 for example, which interestingly has operated from dirt strips. It's a niche market. I don't know how many more 321s they would have sold. If you think about it, the backlog is filled anyway.

A321 is roughly 20 tons per wheel. 777 is about 29 tons per wheel (for a 300ER) but it's a much bigger wheel. Actual pressure over the contact area is probably higher for the A321.

Indian Airlines only recently started getting A321's and I believe they've addressed the runway strength problems where they fly. The A320's have been around for a long time.

Exactly how many of these did Airbus produce in this landing gear format? That is really a surprising sight!

To clarify, the 320-100 had no gates. However very few were produced (less than 20) before the -200 came out with the gates (they're not really called winglets).

You are correct. I had a brainfart. It was very late.  Wink

I meant for the entire A320's family history (From the start until now) regardless of operator. I'm assuming they only built a very small few like what Boeing did with the 737-100 which was about 30.

Fewer than 20 IIRC. But the aircraft remained the same internally if you will. No stretch or anything major like on the 737-200.

Nope. It was a special order if you will. Since no one else wanted it it was discontinued, much like the folding 777 wings.

But I'm sure if you pay enough.  Wink

Pardon me for sidetracking the thread, but Boeing.com states 30 731's were built and delivered. This was also pointed out in another thread not too long ago.

So only 4 were built in that config. Thanks, Hawk.

Thats Incorrect....There were more than just four.Should have been 30+.I stated the number of Wheels on each MLG.

25 AirframeAS : Totally my bad. I misunderstood you. I apologize. I stand corrected!
