I was looking at flights at ORD on flightaware.com and noticed a UA 744 departing from ORD to LGA.

The link:
http://flightaware.com/live/flight/UAL836

According to flightware UA 836 does PVG-ORD-LGA. I'm sure this is just an error by flightaware but I wanted to be sure. Can LGA even handle a 744?

Edit: Its an error since now its showing UA 836 as a 752 and 744 departing at the same time.

No. This is a continuation flight. The 744 runs PVG-ORD, and then a different airplane flies ORD-LGA.

It is a Flightaware error.

LGA could not possibly handle a 744 landing. The runway piers would collapse......

For the sake of argument, why not ? The weight bearing capacity for dual tandem landing gear aircraft is listed as 360,000 lbs. for both runways at LGA. While logistically it may be a bit challenging with regard to gates and wingspan taxiway limitations, if a 747-400 was light enough, why wouldn't it be able to ?

On flightaware you can often find these a/c errors for flights that are continuation with a/c change en route. Another example that often comes up is the UA flight LGA-IAD that continues to EZE (UA847 shows 767-300 but the domestic segment is usually a 757 - at least when I've taken it).

Why not, because even if technically a 747 could land there, the Port Authority, who runs LGA would not allow it.

Could you even imagine the uproar from the community around LGA if the PA allowed this, the politicians would go ape$hit and the person who okayed it would definitely be out of a job.

The wings would clip the terminals upon taking off...lol  Big grin I beleive AA flew a A300 as a replacement aircraft last year. There are marking on some jet bridges at AA for the A300.

The runways are only 7000' long, whats the takeoff distance of a 744? I suppose you may be able to land one there but would you be able to get it off the ground again?

That idea reminds me of the 707 that landed at OSU and they had to strip the plane of all the seats and such to get it off the ground again on such a short runway.

The 747 can probably use a 7000 ft. runway at low weights. For that matter I think that the VC-25s have used shorter runways. I bigger concern would be taxiway/ramp/gate space I think.

Agreed, I was just curious if it would be able to lift off with such short runways

Not to mention the correct flight/aircraft is listed right below... 752

Yes the 747 can use a rwy of 7000ft or alittle less. Obviously it cant be that heavy though. Ive seen them land in RFD for a diversion, have 90k lbs of fuel on board, all the pax and cargo from NRT and take off on the 8200ft runway.

In JVL (janesville, WI) i believe there longest rwy is 7200ft and a VC-25 has been in there once or twice.

Ive seen an empty Polar 744 take off out of RFD and head to ORD in lesss then 3500ft of rwy...it was amazing.

Possibly because a 747-400 weighs just shy of 395,000lbs. Empty.  Smile

Also, 747s don't have dual tandem landing gear. They have double dual tandem gear.

It's called "change of gauge", same flight number, but change of type of aircraft, happens all of time.

I believe that the Jepp diagram has a note stating that B744 aircraft cannot taxi at a speed greater than 10kts...

They'd get no complaint from me! The only reason I'd be pissed is if I missed it flying over my house on the approach to 04.

No problem. Though that isn't to say that a 747 can't land at LGA. You can land above the published weight limits as long as you clear it with the airport management first. They have the pavement data, and they know what the runway can actually handle (more than what's published).

But with JFK and EWR so close by, and the size restrictions of LGA, flying a 747 in there would be a lot of extra hassle for marginal benefit.
