Telling The Difference Between, 767, 300, 310, 330

Thu Oct 19, 2006 12:24 pm

I was spotting in a very nice area of Newark today if you can believe that, the Ironbound, and I was able to distinguish the 777, 340, the 757 and the 737. I did have problems with the 767 and the other large airbus aircraft. One I couldnt tell was a LOT jet. Also, I had trouble identifying an TAP aircraft. Any clues on this differentiation? How about the differences between 319, 320 and 321. Thanks all.

The 767 and 310's have the main gear tilting forward...the 310 has a wing fence versus a wing tip.

The A300 has a wing fence versus the tip and the 330 has the tip.

I believe a wing fence is a small triangular end piece of the wing. A winglet is the mini wing that extends from the wing straight up kind of a mini wing at the end of the wing but extends up to the sky.

767s: The fuselage at the tail area is curved (in a cone shape)
310s: The fuselage at the tail area is straight, -300s have wing fences or a triangular shaped ending at both wings
300s: The fuselage at the tail area is straight, -600s have wing fences or a triangular shaped ending at both wings (although of different shape than those of the A310-300s)
There are many other differences and I couldn't be mistaken unless standing really far from the object. You'll get the experience.

It is hard to describe all the differences maybe it would be the best to look at pictures of all the aircraft you have trouble to identify.
For me the best way to distinguish the 767 from the Airbus widebodies is the nose section. Look at some pictures and you will know the difference. Also the Airbus widebodies have a wider fuselage than the 767.
The A300 and A310 are much shorter than the A330 have a shorter wingspan and lack the huge winglets.
The A310 is more stubby than the A300 because it is a shortened version.
The A319, A320, A321 are basically the same aircraft with different sizes.
The A321 is easily to identify because it is a very slim and long aircraft the A319 is the shortest (okay there is the even shorter A318 but this is only uses by very few airlines in America you will find it only with Frontier and Mexicana).
Also the A32x family can be identified by the number of exists but I never bothered to count them because I think it is easy to say be the size and proportions of the aircraft.

A319 has one small over wing exit (except Squeezyjet who has two, due to larger number of seats), A320 has 2 small overwing exits and A321 has no overwing exits, but two sets of large normal size doors behind/in front of wings.

From a Layman point of view.
The B767 has the Tail section Tapered Below & Above,unlike the A300 which only Tapers from Below.
The A330 has Winglets.
The A310 is much smaller than the other three.

Thu Oct 19, 2006 8:00 pm

Well, first off, I cannot tell the differences between each types of 767s, 777s, A340s, A330s. That takes very good eyes and a lot of knowledge.

On the other hand, here is the way I distinguish them:
777: the 3-wheels side view of the main landing gears usually gives it away.
767: 2-wheels side view of the main gear, fuselage resembles a smaller version of the 777.
757: 2-wheels side view of the main gear, fuselage a little sleeker and thinner than its cousins the 767 and the 777.

A330: Twin-engines, 2-wheels side view, sometimes hard to distinguish from the 767, but I've always found the 330 to be a little "sleeker", oh yes, a lot of them have winglets, which you do not find on the 767 (I don't think).

A340: Only single-level four engined plane

A319/A320/A321: I have no idea.

Sometimes, just by recognizing the airline gives you some clue as to what it is as well. I.e., UAL doesn't fly the A330, so if you're confused between A330 and the 767, it's probably a 767.  Smile

Fri Oct 20, 2006 1:49 am

Easiest way to tell the 319/320/321 apart is simple: The 319 has only 1 overwing exit, the 320 has 2, and the 321 is about the length of a 757, so if you cant figure that one out youre plain blind.

The 767/300/310 is fairly simple as well. On the 767, there are no wing tips of any sort, except on the -400 whoch has "raked" wing tips. The 300 and 310 both have the afore mentioned "Fences". The easiest way I have found, though, is on all airbus wide bodys (300/310/330/340), the last 8-10 windows start to slant up. Supposedly this is to keep the passenger compartment located in the widest part of the aircraft, but any way you look at it it makes spotting easier. Also, if you are close enough, the 300/310 is odd in the fact that there is no "belly bulge" under the aircraft where the wing "attaches" to the plane. This is the only large commercial aircraft that I have seen this on. The wing just kind of dissapears into the fuselage.

Hope this helps.

Quoting NYCFlyer (Reply 13):

The "Mains" alwasy refer to the gear under the wing. The nose gear is pretty much just for balance and steering no matter what aircraft type we are talking about, fron Cessnas to 777's. Someone please correct me if I am wrong, but I have been told that about 90% of the weight on a 737 rests on the mains.

Quoting NYCFlyer (Reply 13):

They're the back wheels. I think they're called the "main wheels" because without them, it'd be really really hard (if not impossible) for an airplane to land without them (some planes have landed with disfunctional nose gears). And as someone stated up there, the majority of the airplane's weight lies on those wheels.

Not "a lot". All 330/340 have winglets. Also the wing has significant "gulling". In general, Airbi have gulled wings (like a seagull) and Boeings have straight wings.

No. Older 300s do not have fences. Only the 300B4-600.

The fuse taper shape at the tail makes it easy to tell Airbus widebodies from Boeing ones. All Airbus widebodies except the 380 have a straight line top of the fuse all the way to the tail. Boeings do not.

It doesn't matter. They sell better than their Airbus counterparts!  Wink

(sorry, I couldn't resist that one... and yes, I'm only joking.)

773's of all types are longer than 772 and have an additional passenger door.

772LR's have raked wingtips, 772A and ER do not.
773ER have raked wingtips, 773A do not.

Can't really tell difference between 772A and ER externally.

Quoting PA110 (Reply 21):

Yeah... the only way you would be able to tell is:
1. The airline requested the model number be painted on the outside (many do). Thai's new 772ER's only have "777" on them where as many list "777-200ER" or "777-300ER" (like SQ)
2. Could like inside the wings and compare the drastically different sized fuel tanks.  Wink
3. Could get close enough to read the model number of the motors. (when listed on them like the frame model number).

They are identical aircraft from the outside.

You can tell a 772ER SOMETIMES because of the extra beefy gear option that Boeing sells. Airlines can order the -300ER gear on the -200ER and there is a beefier look to the gear.

Actually, the A318 DOES have a taller and "pointier" vertical fin than the A319/320/321 (it's not just an optical illusion). It's because, without the taller fin, there wouldn't be enough of a moment generated to balance/control the plane. That's also why the 747SP has a taller vertical fin than the standard length 747s.

Close but not correct, doors 2L/R and 3L/R are emergency exits and they are smaller than doors 1L/R and 4L/R. I work with them quite often at work here in the hangar.

Quoting SWACLE (Reply 15):
the 321 is about the length of a 757, so if you cant figure that one out youre plain blind.

Again close but not correct. The B757 is just over 9 ft (3m) longer than the A321. That is at least an 18 seat difference (3 rows of 3 x 3).

We can squeeze two A32X easily side by side in the hangar here at work. We can fit a B757 and an A32X side by side. We cannot fit two B757s side by side (wingspan and length wont permit it).

I didn't see it mentioned the 1st check if you are unsure if it's a Airbus or a Boeing aircraft is to check the flight deck windows. Boeing Airplanes have an almost 90 degree upper edge of the last flight deck window and the Airbus planes sport a tapered angle on the same window.

Then you can start looking at specific parts of the plane for what type it is.

To me the harderst to tell apart is the A320 series (A319 vs A320) and the 787 NG series (737-400 vs 500/700 vs 800). To me the widebodies are easy to identify with the number of differences in number of wheels and type of winglet or wing fence ect...

Just my .02 cents.

Hi folks. You talk about the difference between these planes. What about the 737-3xx and above series. I have more trouble with them than any. The 757 is the easiest plane to spot. Thanks for the info on the 318/319/320/321. Have a good day.

There are two ways to tell an A300 from an A310: One is by the number of passenger doors. The A300 has 4 doors on each side: The A310 only has three. Also different is the number of flap "canoes" under each wing. A300 has 5 on each wing; A310 has 4.

The A310 also has a quite noticeable dihedral (upward angle) between the engine and where the wing trailing edge meets the fuselage.

The A330 looks like a stretched A300 with a fuselage fairing between the wings and winglets extending upwards from each wingtip

Easiest way to tell a 767 from a 777 is by the landing gear. As before mentioned, the 767 has four wheels on each bogie which tilt forward. The 777 has 6 wheels on each bogie which tilt backwards. And that's if you can't tell by the size difference, as the 777 is basically a 767 on steroids.

Quoting BrightCedars (Reply 6):
767s: The fuselage at the tail area is curved (in a cone shape)
310s: The fuselage at the tail area is straight,
300s: The fuselage at the tail area is straight,
There are many other differences and I couldn't be mistaken unless standing really far from the object. You'll get the experience.

Indeed this is the best and possibly the only way to distinguish between those planes. Of course, the wing tips make a big difference, but not all A300 or A310 are equipped with them.

The 777 and 767 share the same nose section. The noticeable difference is the tail. the 767 one is round (conical) , the 777 has that amazing cool flat tail.

Plane-spotting - always a great joy to do! Generally speaking it takes some time to recognize the different models. Here are some tips though:

A318, 319, 320, 321 - A318 is the shortest and has a taller fin than the others (all of which have the same size of fin) and is also the least common of the 4. A319 and A320 can be easily confused, especially if viewed from below (eg on take-off) but side views will indicate the longer fuselage and twin window exits of the A320 versus the one window exit on the A319. Note though that U2's A319s have twin window exits to facilitate a higher passenger capacity. Then again, U2 does not fly A320s... Some Indian Airlines A320s have twin main landing gear - it was the only airline to purchase this option from Airbus. It is purchasing newer A320s which will not have this option. 18 A320s flown by AF (13) and BA (5) do not have the wingtip fences that all other A320 family planes sport - these are the earlier and lighter model 100s. The A321 is much longer and has four exits on each side, none of which are overwing.

Boeing 737 variants - the 100 is virtually extinct now. The 200 has the long, slim Pratt & Whitney JT8D engines slung underwing while all other models have the wider but shorter CFM56 engines which are suspended below the wings on pylons. To tell the NG models from the Classics can be quite tricky. The easiest way to tell if you are observant is the location of the pitot tubes on the fore fuselage. The Classics have 2 tubes located below the third of the cockpit windows on each side, the NGs have 1 per side located below the second window. New NGs are delivered without eyebrow windows but enough have been delivered with them to ensure that this feature is insufficient on its own to distinguish them all. The tailfins of the NGs are also taller and slimmer than those of the Classics but this distinction tends to require practice to become apparent. Many NGs are being delivered with tall winglets but winglets are being developed for the Classics.

Thus, the 737-500 and -600 can be distinguished in these ways, as can the -300 and -700. The -800 is longer than the -400 in addition to the above. The -900 is even longer and the stretch is quite apparent. The new -900ER will have an additional aft exit per side, enabling distinction from all other NG models.

A300, A310, A330 and 767 models - can be tricky initially. The 767 has a narrower fuselage and the cockpit window arrangement is the characteristic Boeing pattern also seen in the 757 and 777. The Airbus pattern, common to all models, is somewhat different. Many exit arrangements have been used on the 767s (especially 300s) so this is of little use. The A300 is longer than the 767-200 and is comparable to the -300; additionally the A300B models have an aft dorsal fairing housing a VHF aerial. This feature was deleted on the A300-600 models, which also feature wingtip fences. The A300s also have larger tailfins than the 767s. The A310 is much shorter than the A300 (it is effectively a chopped version); only the -300 models have wingtip fences (not -200s). No 767 has winglets but the -400, which is the longest model, has raked (angulated) wingtips.

The A330 is a totally new model from the A300/310 (not merely a revision, as some erroneously believe) developed in tandem with the A340. The A330-300 is longer than the A300 and has large winglets (not small fences). The -200 is shorter than the -300 and has a taller tailfin but the winglets are retained.

Hope this helps.

The easiest way to tell if it is an Airbus or a Boeing is to look at the window line. If it is straight all the way from the front to the back its a Boeing aircraft. If the last half a dozen window angle up its an Airbus aircraft.

Another way to easily identify if that twin engined widebodied jet that just took off is an A330 is to look at the trailing edge of the wings, which feature a stunning taper down and into the fuselage - one of the most graceful features of any airliner around. The A340 also has this taper but four engines give it away more easily.

I also think of Boeings as having sharper vertical stabilizers, more angular. Airbus vert. stabs are generally more rounded.

The 767's nose section looks different from the Airbuses - it's a little stubby and short, whereas the Airbuses have a sleeker nose section. That and of course the tailcone and the forward-tilting main gear would give the 767 away.

You can also identify the 757 by looking at the nose section alone, it has a slight downward angle and the fuselage is much thinner than its widebody cousin.

You can tell A330s from A300s by the longer wingspan. The A310 is similar to the A300 except that it is shorter.

773s are much longer than 772s - that way you can easily tell tham apart, just like the A346s are much longer than the A345s.

Yeah the A.net quiz really helps!!  Smile

Quoting Hamster (Reply 3):
I believe a wing fence is a small triangular end piece of the wing.

Just a point, a fence is plate usually mounted on the forward edge of the wing, on airliners generally they are mounted approximately 1/3 to 1/2 the length of the wing from the fuselage this is to improve stability. The Thing on the end of the wing of the A-300/310 is know as a vortex dissipator and is designed to do much the same job as the winglets or longhorn tips and that is to reduce the amount of pressure bleed off the wing ends.

Quoting Pdxcof9 (Reply 17):
The only way for me to tell the difference on F9's 318 and 319 is to read the number on the plane

The 318 is in fact 4.5 frames shorter than the 319.
The wings are the same on the whole 320 family except for the addition of an extra track on the back flap of the 321 which can be seen by the extra fairings at the back of the wing

I can usually tell the difference between Boeing and Airbus by the shape of the windows. Also the curvature of the nose. The 777 and 767 are easy to id by the size and scale of the tail compared to the fuselage. The 777 tail is smaller.

The flap tracks (aka canoes) on the back are slightly different. Classics engine pylon tapers back into a canoe(i think its called that?)
Some see lines, others see between the lines.

The 767 and 310's have the main gear tilting forward...

The forward tilt of the mains on the 310 is not as pronounced as the 767. The 330's mains tilt rearward (same as the 340). I tend to look at the 330 as a 340 with two engines instead of four.

One way I have always been able to identify an A300 vs a 767, which was one of my biggest confusions when I first started to get to know about airplanes, is the wing on the A300. If you look at the A300/10 wing it has several large pontoon fairings. Whenever I would go plane spotting in AA terminals at JFK, MIA, or LHR, back when they flew the A300 there, I would always look for those 5 or 6 pontoon fairings sticking out the back. I actually flew on an AA A300 once from ORY, on a temporary substitution once, complete with 3 classes of service. Fine bird, I guess, but I prefer the 763.
A318/19/20/21, A300, A332/3, A343/6, A388, L1011, DC-9, DC-10, MD-11, MD-80, B722, B732/3/4/5/7/8/9, B743/4/4M, B752/3, B762/3/4, B772/E/W, B788/9, F-100, CRJ-200/700/900, ERJ-135/145/175, DH-8, ATR-72, DO-328, BAE-146

Quoting Starlionblue (Reply 18):
The fuse taper shape at the tail makes it easy to tell Airbus widebodies from Boeing ones. All Airbus widebodies except the 380 have a straight line top of the fuse all the way to the tail. Boeings do not.

The 747 rear fuselage top is straight, with the bottom sweeping up. But you don't need to look at fine points like that to recognize a 747. The 707's rear top fuselage is pretty straight too, but they don't come around much any more.

From some angles, the transition of the bottom line of the fuselage from straight to tapered looks almost jarringly abrupt on the 767 and 777, whereas the Airbii have a more gradual transition. The A350 renderings look like it will have a sharp transition to a bi-tapered cone like the Boeings.

The 777's APU exhaust also noticeably comes out on a chamfer on the left side of the screwdriver rear end.

The flap tracks (aka canoes) on the back are slightly different. Classics engine pylon tapers back into a canoe(i think its called that?)

That's the best way to ID 737 Classic vs. NG when you are sitting in one looking out. Also, the Classic's non-engine flap track canoes are small and pointed, whereas the NG's canoes are bigger and rounded at the rear. The NG's flaps run uninterrupted behind the engines. The Classic's engine pylon has a squared off leading edge, while the NG's pylon is more bullet-nosed. If you see blended winglets, it is an NG.

From below, the NG is distinguished from the Classic by its longer wing span.
