Why Is The 777-300ER Called The 77W?

Mon May 14, 2007 4:58 am

Does anybody know what the W is supposed to stand for? I find it odd because both the 762ER and 763ER are coded as 762 and 763 respectively. Same with the 772 and 772ER, so why the change in this standardization with the 773?

The 77L and 77W are physically different than their precesessors, unlike the 762 and 763. They're about 14 feet wider, if I'm not mistaken, so classifying them differently could be valuable to ground controllers as well as the company employees on the ground.

The worldliner is the 777-200LR, which is abbreviated 77L.

14 feet wider? That can't be true, and the different 772 and 773 models have the same respective lengths. The only difference I could find is that the longer range 777's (77L and 77W) have a slightly larger wingspan (60.9 vs. 64.8 meters).

Would the difference in wingspan be enough to have the plane classified as a different code?

Yes, as it can affect ground ops. So the (almost) 14 foot wider wingspan of the 772LR and 773ER would mean they might not be able to as easily squeeze through an opening compared to the 772, 772ER or 773. So it would be helpful for Ground and the Tower to know they're dealing with a wider (via wingspan) plane.

So most carriers seem to use '77W' for the 773ER but it seems NH doesn't abide by these rules and uses the generic code 777 for all of its int'l 777 ops.
On domestic schedules, '772' is used despite the fact that most flights are not 772ERs and 777-381s are '773.'

Yes. The original 777s were "200 foot" planes, fitting in just a hair under 200 feet width.

The 777 longer range aircraft (77F, 77L, 77W) have the same wingspan (roughly) as the 744.

200 feet width or 200 feet length?

I'm guessing everyone is talking about wingspan and/or fuselage length.

737-400 = 734
737-500 = 735
737-700 = 73G

They probably chose 73G for the -700, because "737" already means 737 - all series, and the G is the seventh letter of the alphabet. FYI, 737-800 = 738, and in the same logic as 73G, the wingletted 737-800 is known as 73H.

As I understand it, though, the "200" in 777-200 does not refer to the width / wingspan of the aircraft, it refers to the passenger capacity. Thus, 772's (ER & LR ) can carry 200+ passengers while 773's and 77W's can carry 300+ passengers.

That is where the numbering designation originates, correct?

Dont think so. Following that logic, the 747-8 can only carry 8 passengers and the 747-100 can carry 100 passengers?

-100, -200, -300, -400 is simply a way to differentiate between models. When there are varying versions of specific models (like 777-200, 200ER, 200LR) they user letters (ie 77L). Most airline configuration gets even more specific, for example some of Qantas's 747s are 747-438. For handling purposes it will be refereed to as a 744, but internally it is a 747-438.

Adding to Oraka's explanation, after the 747, Boeing skipped the -100 series as these were seen as the less efficient versions with toothing problems. Now it's all messed up even more, that both Airbus and Boeing start their newest models A350, A-380 and 787 with -8 or -800 versions instead as 8 seems a lucky number.

Boeing doesn't determine this. The determination is made by IATA who publish an annual "Coding Directory" that incorporates all of this and more.

The "W" and "L" in the 77W and 77L don't stand for anything particular. Similarly the "H" in 73H or numerous other examples. These were selected by a committee who probably used similar logic to what was mentioned here when coming up with them, but officially are just random selections.

I guess I should have better explained my point. . . I realize that my comments don't make sense when applied to the entire Boeing and Airbus fleets. But I was not saying that Boeing relied on passenger numbers when designating all aircraft like the 747-8 or 737-9 -- obviously the 739 doesn't carry 900+ passengers. My comments were limited only to 777 designations. I recall reading that Boeing decided to use aircraft capacity when designating the 772 and 773.

The -100 models for the 757, 767 and 777 were reserved for future shrinks of the "baseline" -200 configuration, but the economics never worked out so they never were formally developed. In the case of the 777, the 777-100 would have been a shrink designed for ULR missions and this role was taken by the 777-200LR.

Well, in this precise case, it only means that it is a 744 initially delivered and configured for QF by Boeing. If QF gets a second-hand 744 from, let's say, BA, it will be called a 747-436, and that number will follow the aircraft until the end of its life, whoever operates it.
Ironically, this system does not even tells apart engine types: BA has two subfleets of 772ER, one with GE engines, one with RR engines, and they are both called 777-236ER..., while GE-equipped AF's 772ER (identical to BA's) are named 777-228ER, or SQ's RR-powered are 777-212ER.

Airbus uses the engine maker and engine generation for the code, and 2 airlines with identical engines will share a same code (eg 380-841, 4 standing for RR, and 1 for 1st generation of the RR engine -implicitely the A380 RR engine-)

Uh, no. Has nothing to do with either of those.

The "2" is used because the initial plans for a 777-100 were scrapped, and "00" is Boeing's production code. Thus, an undelivered (or generic name for the) aircraft is 777-200.

Once the aircraft is completely outfitted for delivery, the "00" becomes the code of the company whose specifications it was built for. Delta's code, for example, is 32. So a 777-200ER built for them, would eventually be delivered and operated as a 777-232ER.




.....keep in mind this only applies to Boeings. Airbus' code specifies the derivative type, the engine type, and the production version number.
