Whats The Difference Between The 773 And 77W

Tue Oct 04, 2011 10:30 pm

Dont know if this is in the right forum, but here goes:

Can anyone tell me the major differences between the 773 and 77W. Does one type hold more passengers, fly further, or take more cargo.

Reminds me of the porsche 911, lots of different types but hard spot the differences.

Toughened up structures, more powerful engines, raked wingtips, and larger tanks characterize the 77W Vs. the earlier 773. The range went up by over 2000 nm, which is a pretty big jump, and the MTOW went up too - making the 77W a very useful aircraft. In comparison to the 77W, the 773 now seems almost like a short-range version. Consequently, once the 77W was introduced people stopped buying the 773. There are only 60 of them, Vs. ~300-and-growing for the 77W.

Many thanks for the information, can see why the 77W is the one to have with a 2000nm extra range.

There are some airlines, however, that make economic use of the 773 - CX and SQ are 2 in particular. Because they have lower weights, because floor space is the same, if range is not an issue (e.g. 8 hour mission from SIN-SYD), then it is usually more economical to send a 773 than a 77W assuming configuration is identical. In CX's case, its 773's are configured in a more economy heavy configuration than its 77W's and is mostly used for runs through SE Asia, Japan and South Korea - the added weight of the 77W costs more to haul around.

Different planes for different missions - the 773 suited airlines like SQ and CX who were replacing 742's and 743's for their 3-4 hour regional routes - the 77W is a plane designed for 744 type (and obviously longer) missions. The 77W is capable of a lot more but if you were running an airline that had no routes over 8 hours (like SIN-NRT), then I would query whether the 77W is the right aircraft. For CX and SQ who both use the 77W on shorter routes, their 77W's fly 12+ hour flights regularly so the "intelligent mis-use" (as CX calls it) of the 77W isn't a problem.
M88, 722, 732, 733, 734, 73G, 73H, 742, 743, 744, 752, 762, 763, 772, 773, 77W, 320, 332, 333, 345, 388, DH8, SF3 - want

Bigger fuel tanks, higher MTOW, stronger engines as well as everything else = more range.

The 773 was simply a stretch of the 772. The 77W was totally reworked to make it a proper long haul aircraft...

Yes, four of them. HL7532 (28371), HL7533 (27948), HL7534 (27950), and HL7573 (27952), all delivered in 1999/2000. Like CX, KE uses them with higher density interiors on routes around Asia. The interiors are configured F12 C28 Y336, where KE's 77W interiors are configured F8 C56 Y227.

The 77W's at both CX and SQ are in such high demand in their long haul divisions that there aren't many regional ops run using them. They only pop up where it makes sense for them to do so with regards to scheduling and aircraft utilisation (or when it goes onto a long haul leg, ie SQ on the way to SFO).

The 777-300 & the 777-300ER are planes of two different eras. When the 777 was new in the 1990's airlines wanted a longer plane so the -300(no ER) was born with the same engines as the 777-200ER. The 777-300ER entered service in 2004, as a derivative of the 777-200LR. IT is really a very different plane that has found a market as a 744 replacement, no wonder the 748 has sold so poorly.

The 77W has found it wings with Cathay Pacific, it ordered 60, flying all the way from Hong Kong to JFK and Toronto. Emirates also uses them, they have 100, from Dubai all the way to LAX and Sao Paulo. These 2 airlines have pushed the limits of the 77W's peerformace, can't wait to see what the 777NG does.

Sorry to nitpick, but technically the 77L is a derivative of the 77W -- the 300ER was developed first, then translated into the smaller frame.

I though they were closer to 60 77W's. Overall 777s probably still falls short of 100.

This has been the case-the A330 has decisively won the airlines where very long range is not required. As the A330 has been improved it has proved to be more economical than any version of the 777. However, the A330 does not have the range of the 77W, and so where extremely long range is needed there is no substitute for the 77W. As others have noted, having the long range capability has its penalties in that even when you are not carrying all of that fuel you are still carrying the structure it requires. This is why both the A330 and the 77W are selling well (at least until the 787 becomes readily available, at which point A330 sales will dry up) and the 77E is not selling.

This is true. The 77L was an offshoot of the 77W, and Boeing wasn't even going to develop it until a few airlines asked for it. It was a logical byproduct of the 77W, as it incorporated all of the changes with the shorter fuselage, but Boeing did not figure there was enough demand for it. That is why the 77W entered service over two years before the 77L. PIA was the launch customer for the 77L, but as I recall there were others that wanted it.

"current" being the key word here  
However when the 773 was bought by these airlines, for these missions, the A333 was no where near the quality plane that it is today. One also has to wonder if SQ would be flying A333's at all had it not been for the A380 delays. I don't mean to rehash this discussion but for so many years SQ denied interest in the A330 only to order a bunch at the exact same time that they were negotiation compensation for the A380 delays. It has to make you wonder.

B777-300 = B773
B777-200LR = B77L
B777-300ER = B77W

Must be somebody at Eurocontrol, bored, wanting to confuse people and then laugh at them  

These are the official ICAO abbreviations that appear on Flight Strips, and Digital Flight Strips in ATC units.

there are 6 variants total

777-300ER - 77W

777-200LRF (77F)

the 772A is used in select carriers in Asia and middle east as low-weight regional places, but even those are being gradually phased out (eg SQ). UA might have some 772A planes too doing TATL segments.

A copy & paste out of the latest ICAO DOC 8643 (2011) reveals the following:

Quote:

BOEING
===========================
777-200...........B772.......H........L2J
777-200ER.......B772.......H........L2J
777-200LR........B77L.......H.......L2J
777-300............B773.......H.......L2J
777-300ER........B77W.....H.......L2J
777-F.................B77L......H.......L2J


This means that the only official designators are B772, B773, B77L and B77W! Any other (invented/madeup) abbreviations for any 777 variants are simply industry jargon, and not ICAO, and therefore not worthy of differentiating between since ICAO only assigns new designators when a variant performs significantly differently.

What surprises me however is that they didn't assign the freighter with a separate designator as is usually the case with, say for example, the B74F   

EDIT: I take the last line back! The B747 Freighter is also not referred to as a B74F. I also looked up other freighters and these too didn't have the F suffix, so I am guessing the "F" is just industry jargon!

Which makes sense if you think about it - the aircraft performs the same way regardless of what it is transporting inside. A freight 777 does not handle any differently than a pax 777, nor does it require any special handling by ATC.
Public service announcement: "It's" = "it is". To indicate posession, write "its." Looks wrong, but it's correct grammar

There is no B77E ICAO code because the 777-200 ("A") and 777-200ER are identical for all ATC and airport purposes. ICAO describes both aircraft with the B772 code.

The 777-200LR and 777F have longer wings, so they need a separate code (B77L).

Watch out for dueling IATA vs. ICAO codes... three-character codes are IATA codes, typically used to describe equipment in airline systems, while four-character codes are ICAO codes, used by ATC, in flight plans, and often by airports.

77E is not an official IATA code but appears in a lot of airlines' proprietary code systems, which are usually based loosely on the IATA codes. B77E doesn't appear anywhere that I know of.

Then the 777-200LR was a shrink of the 77W, to make the 777 a proper ultra-long-haul aircraft, and a long-haul cargo aircraft (777-200F, a cargo version of the -200LR)

Quoting tullamarine (Reply 8):
CX and SQ are 2 airlines that show if you have routes under 8 hours, the current aircraft of choice is the A333.

Depends on capacity though. While the A333 is a clear winner over the formerly used 772A, the 773 is unique in the sense that it is much bigger than the 333, both in terms of cargo space and pax loads. The 773 never had any real equivalent at Airbus'. The A346 is identical capacity-wise but has been designed with long-haul missions in mind, and was the first true long-haul aircraft in that size category. Boeing answered to this with perfection however, with the more economical and even longer range 77W.
When I doubt... go running!

Nobody's mentioned the main gear forward strut, have they?
Forgive me as I'm by no means an expert, but the 77W has an extra semi-levered strut running from the main strut diagonally forwards and down to the main bogie. This, I believe 'stiffens' the wheel truck on rotation, causing the aircraft to rotate from a pivot point at the rear wheels rather than the centre wheels, which through some physical wizardry allows a greater MTOW.
Also doesn't the 77W have a more 'hands-on' (or 'computer-on') way of dealing with tail-strikes? If I remember correctly (bear with me, I read about all this in a dog-eared copy of Airliner World only last week!) if a tail-strike is imminent then the plane will automatically correct this before things start to spark and go bang. Although i guess this is not as generally visible as the strut, it's nonetheless another difference for you

RE: Whats The Difference Between The 773 And 77W

One also has to wonder if SQ would be flying A333's at all had it not been for the A380 delays. I don't mean to rehash this discussion but for so many years SQ denied interest in the A330 only to order a bunch at the exact same time that they were negotiation compensation for the A380 delays. It has to make you wonder.

There is no doubt that the best thing to ever happen to the A330 was the A380 delay. Airbus was handing 330's out as compensation to anyone who would take them and a lot of operators found them to be a great aircraft! I think in the end Airbus really was a big winner in that whole mess!

UA might have some 772A planes too doing TATL segments.

United does have 772A's and they fly a lot of domestic and Hawaii trips.

Quoting The Coachman (Reply 3):
The 77W is capable of a lot more but if you were running an airline that had no routes over 8 hours (like SIN-NRT), then I would query whether the 77W is the right aircraft

Dont forget cargo. EK for example heavily relies on cargo. HAM-DXB is just under 7 hours flight, but the 773 has very often been at the maximum payload limits. (It was once explained to me, because the flight was "full", although seats were free...)
The 77W would just laugh and cough that cargo over to DXB.

aren't EWR-BRU/ZRH flown with 772A's too ?

There is a 'soft limiter' in the FBW pitch control system.



If it senses, excessive pitch rate and or angle it will make it very difficult for the Pilot to keep increasing pitch, thus avoiding tail strikes.



Unlike Airbus, however this is not a hard limiting system, if, for example you needed to keep increasing pitch, even dragging the tail in the process, with a little more effort you can 'pull through the limiter'



This situation might occur, for example in a windshear situation during rotation where you might lose significant airspeed and the end of the runway is fast approaching.



With full power and a higher pitch angle you may be able to lift off safely despite dragging the tail.



Better to have a tailstrike than run off the end of the runway.
The best contribution to safety is a competent Pilot.

Thanks for greatly fleshing that out, Max Q! Very interesting, and by far the better system of the two for experienced pilots, i would've thought.

The semi-levered landing gear doesn't allow an increase in MTOW. By increasing the ground attitude for an airplane that is Vmu limited, it allows a shorter field length at a given TOW or a higher TOW from a given field length.

They do.

Quoting aerorobnz (Reply 32):

77E is only seems to be used when an airline operates both the early 'non ER' version as well, otherwise an ER is just a 772....

UA doesn't use 77E.

The sub-fleet of domestic configured 772As are indeed flown on domestic (Hawaii is domestic too, you know) trips. UA also has regular 3 class configured 772As, which operate IAD/ORD and now EWR-Europe runs.

Yes, during take off the angle between the vertical oleo, and the horizontal truck is maintained at 90 deg.
So when the aircraft rotates, it rotates about the axle of the rear wheels, not the bottom of the oleo. This generates more ground clearance.

The length of the flight has no bearing on an aircraft being 'full'.
We dispatch B767s from ARN to LHR at MZFW regularly. The aircraft cannot carry any more payload, but there is loads of space and weight left for fuel. The flight time is only 2 hours, but we could put in more fuel and fly it for 8 hours.

Could you clarify "unlike" what Airbus? And what would "hard" exactly be?
There was that incident of an EK A345 at MEL, where they punched in 2xx tons takeoff weight instead of 3xx tons, realised after V1 and took of with TOGA and screeching tails, just as you said, better tailstrike than crash the woods.

PMUA operated both -ER and non-ER variants of the 777-200. PMCO only operates -ER. Now I can't find anything where UA uses the code 77E.
