Question About 767-300ER

Fri Sep 03, 2004 11:08 am

To major airplane guru's this might seem dumb. But my question is, what are the differences between the 767-322 and the 767-336? I noticed it seems like only BA ans Qantas use the 767-336, as they are the only airlines in the system for it. Also, some 763's have 2 doors, while some have 4 doors. Is one longer than the other? Any help? Just wondering what the differences are in this model.

Boeing issues a customer code number. It is just the same model but with different last 3 digit numbers

It's Boeing's customer code. You will notice that, abliet a few exceptions, no two customers share the last two digits of an aircraft's type...

Boeing 767-3XX (fill in customer code)

United Airlines is 767-322ER for example. Since different customers have different configurations, there are some slight differences

To answer your question, BA and Qantas operate the 767-336 aircraft. -36 is Boeing's customer code for British Airways. All Boeing aircraft have a two digit or combo number/letter code as part of Boeing's aircraft identificatioin system.

Qantas operates -336 aircraft as they leased/bought some of the B767's from BA after BA began reducing the type.

In terms of the door, the 767-300 is available with a number of configurations depending on airline preference. For example, the three configurations I know of:

X= Main/Large Entry Door
Y= Smaller emergency exit door
Z= Overwing emergency exit

1) XXYX
2) XXZX
3) XZZX


Hope that helps/makes sense.

Would more doors equal less room for seats, if the aircraft is the same length w/ four types of configuarations?

Just to clarify, the customer code remains with the aircraft even if it changes hands, as in the example of the ex-BA planes that migrated to Qantas. One can, thereby, determine the original owner of the aircraft.

Type "Boeing customer codes" into a search engine; several enthusiasts have posted extensive lists online.

I have noticed that on say the 762, the overwing exits differ dependent on the number of pax it carries, ie AA762, one overwing, and BY have 2 overwing as they carry 290Y. The same goes for BY 763's they have 3 main pax entry doors and a 757 type emergency exit aft of the wing, which is permanently armed. The 3 main doors are all used for boarding/deplaning with BY and this speeds up the turnaround process. Carriers such as UA, who have only 2 main doors and 2 overwing exits instead, do not need this major time advantage as they carry fewer pax in a 2 or 3 class config and have a bigger time window for turnarounds on routes like JFK-LHR than say BY on a LGW-SFB route. Just a thought.

If one carrier has two different versions of a plane ex. domestic vs trans-atlantic do they get different customer codes?

can someone confirm CO's orders for the 763's are the ones that were delivered elsewhere, and are noticeable as to which ones by having the R2 & L2 doors?

Nope, but in these cases differences tend to be minor (seat arrangement for example) since the carrier wants the option of switching planes between missions.

Ba is the only airline to have ordered 767-300 models with RR RB211 engines. Some of those were leased/sold to Qantas. They carry the -36 customer suffix. I also think Brittania and BA were the only airlines ordering the Collins autopilot with switches to engage the center, left or right channel, instead of the push-buttons. However, Qantas switched the controls to push buttons after receiving the A/C from BA.
Also, BA never switched the ADI's displays from original mode to the newer dispalys with speed scales...any ideas why?

I would speculate that this is to allow pilots to fly other types at the same time. Maybe the L-1011.

IIRC, SAS disables the altitude tape on the MD-8X PFD (SAS only has glass cockpits) in order to ensure pilots could fly both the DC-9 and the MD-80. Or at least that's how a pilot explained it to me.

The reason BA did not change them is probably the same as why WN had Boeing program their 73Gs to read out like the steam gauges on the 732s, 733s and 735s so that they could keep the pilots on an "any plane, any time" system. Keeping older style readouts makes it easier for pilots to switch

Hmmm... poor Blake, he's new--- just saw that.



Guess I'll go ahead and be a softy:

China Eastern (Yunnan) also ordered the RB211 on their 767s  Big grin

I stand corrected on BA being the only airline having ordered for RB211 powered 767-300's, thanks for the update.

Do Chinese airlines just like the more rare engine/airframe combinations? If I'm not wrong this time, China Airlines was one of the few airlines choosing P&W engines on their A300B's.

On the cockpit CRT displays: BA could have changed to the newer version for it's complete fleet of 767's, 757's en 737 Classics, keeping fleet commonality.
I rather think it has something to do with ergonomics. I know they insisted on classic engine instruments for their own 737-400's after the British Midland crash of a 737-400 equipped with solid state engine instruments...
