I can speak to TAV / KLM 737-700/800s Galley2 around 1998. It was very memorable to me because I worked the structure design for the customer intro. TAV was owned by KLM, and KLM wanted to be able to swap planes between the fleets. KLM's 737-800s were ordered with Galley 2a units, that extended past the section 41/43 break. When the TAV customer intro package came down it specified a Galley 2 configuration, galley 2 stayed fwd of the sectio 41/43 break. I worked section 43 structure, so no impact to our group, or so we thought. A couple of weeks before we were due to start building the fuselage for TAV #1 in Wichita, I got a call from the galley group in Seattle asking where the clevis was being installed for TAV. Since it was a Galley 2 configuration, my reply was there is no clevis is section 43. The reply from the Galley guy was that the customer intro called for a Galley 2 with a G2A footprint. GD sales engineers - unless you fully read the description in the config document, and not just the option header, there was no way to discern a new custom galley configuration for the -700. G2As had been installed on the -600 and -800, but not the -700 at that time. So we copied the -600 design over to the -700 stringers and frames, and made some calls to Auburn for a quick run of 2 ship-sets of the new design stringers.

KLM wanted the bigger galley foot print to install G2A modules into the TAV -700s when they swapped the planes so they could carry more duty free.

Which at the time was “European standard “ so not really just for TWA (Two Worlds Apart).

Not a big deal but NWA had blue flap(?) lights in their 747’s prior to -400’s.

Air France on their 727’s had the FE panel in French IIRC - we had to use an overlay prior to delivery.

Australian/Ansett 737-200’s and -300’s had all the overhead panels the same color where Boeing standard had 3-4 panels with slightly different coloring.

What switch configuration is standard now? You refer to TWA as Two Worlds Apart. Out of nothing but shear curiosity are there any other strange things they ordered on their aircraft? Sorry for so many questions but you’ve intrigued me :)

That’s what all the old guys used to say TWA stood for back in 1980+\-. Even when they got 767’s they went their own way on some of their cockpit selections (too far back for me to remember exactly) but as with many airlines it related what their senior captains had a cozy warm feeling about from the days of the DC-3.

European or American standard isn’t such a big deal anymore since we’ve gone from fore/aft switches to push buttons on most new airplanes but still crops up with the light switches. Most airlines except for a few are American standard - forward is on.

Didn't the Ansett 767s built new for them include 3 man cockpits (even though 2 man cockpits were the standard) due to Australian aviation laws of the time requiring a flight engineer? Remember reading that somewhere.

My understanding is that the FE on Ansett's 767s was a labour relations issue within Ansett only, as QF took delivery of 762s with two-crew decks at a similar time.

The SFP (Short Field Performance) modifications Boeing developed with G3 to allow 738s to operate at SDU (and CGH?) come to mind. Though I’m not sure if those are mere software enhancements or something more.

Is it possible for a second hand operator to have this reversed if they would like or are they stuck with whatever was ordered from the factory?

They were certainly the first at Air Canada. Years later, with the merge with Canadian, the like fleets of 767s, 747s and A320s showed that Canadian's were imperial while Air Canada's were metric. I am not sure about the rest of the world. Air Canada's first 767 was delivered in October 1982 ... were there any else in the world operating in metric at that time? I am guessing that in the USSR or China, likely there were.

Airbus basically custom-made the A350-900ULR for SQ after they requested it.


The A350-900ULR isn't really a "custom" airframe, however. The A350-900 had more physical fuel volume than usable and the ULR modifies the software and some of the ancillary hardware like tank inerting and sensors to allow more of that physical volume to become usable volume.


OA940 wrote:
Pretty sure the 787-3 was basically custom-made for the Japanese, like the 747-100SR and 747-400D.


It ended up being a "Japanese-only" model, but Boeing did actively market it to other carriers - there was just no interest.


OA940 wrote:
Also with the A350, I think PAL's extra weight version is a special request.


Airbus determined that the A350-900's undercarriage could support higher operating weights than originally offered and made them available. So the 278,000kg MTOW PA is using is actually a de-rate from the 280,000kg offered in WV010 and WV013 (as well as the A350-900ULR).

I remember when KLM used to bring their 747-300M and -400M into MSP back in the 90s.

Don't know how common this was, but Hawaiian Airlines used to operate DC-8 Combi freighters, as well. I flew on one of those from Clark Air Base in the Philippines to Diego Garcia back in 1987.

As Air Canada flies in FIRs that are predominantly Imperial, altimeters and airspeed indicators are in Imperial. The imperial/metric conversion for altimetry and speed are cumbersome at best.

All weights, not just fuel, but performance and weight & balance are in metric as well. As are engine temperature gauges (but this is more common).
Just because I stopped arguing, doesn't mean I think you are right. It just means I gave up!

This wasn't unique to Indian Airlines in terms of a custom modification for the airline. It was a valid option that Airbus offered on the A320 series for many years after launch. Indian was the only carrier that took up the option. These are no longer available to order on the A320 series and hasn't been for about 10 year.

One airline that had custom mods by Boeing was Ansett who had fully customised 767 cockpits that included a Flight Engineer panel for a three man crew. The 5 aircraft delivered were the only ones like it in the world and stemmed from a union dispute that forced Boeing to create an FE panel despite the design of the aircraft only being for a two person crew.

I imagine it could be done by just swapping out the panels - might be a paperwork nightmare unless somebody has already done it.

As for Ansett and their 767’s, Boeing initially designed the 767 as a 3 crew airplane and IIRC the first few built which were used for certification were 3 crew and later modified to 2 crew prior to delivery. So realistically any airline could have ordered 3 crew if they wanted to - Boeing didn’t take a 2 crew airplane and redesign it for Ansett, it was designed that way to begin with.

Surprised nobody has mentioned the classic 707-138 built for Qantas (later the 707-138B). The shortest bodied 707 built, but with huge range as a payoff for QF and their long stretches.

Despite the extra cost of hauling less passengers these proved popular on the secondhand market after QF upgraded to the Intercontinental 300 series. Notable users were Laker Airways for charter work.

The 2 SP’s Saudia had we’re actually VIP birds, not used by the airline. IIRC RR engines were required because the Pratt engined SP’s didn’t have the range to get from Saudi Arabia to Cleveland(?) where the King’s heart doctor was located. RR became an available option so Qantas ordered a couple.

The CFM-engine for the A318 was only offered by special request from Air France, although many airlines switched to the CFM-engine after their initial PW-engine order, as the PW-engine hat trouble meeting the promised specifications.

BWIA had a larger rudder on their L-1011s from all of the other airlines. It can be seen in the different shape of the sweeping curve between the #2 engine exhaust and bottom of the rudder.

Pan Am had a larger C-2 cargo compartment on their L-1011-500s by eliminating the bulk C-3 compartment. Thus, PA L-1011s had no C-3 cargo door.

The modifications for missile protection by LY are done by LY itself, regardless of whether the aircraft is owned or leased.

Also, Saudi Arabia's Boeing 747-300, HZ-HM1A, has lower-deck doors R2, R3, L2, and L3 deleted and not even a plug there. This bird has only 8 doors instead of 12.

Later in their careers, IINM, Kalitta Air had Boeing 747-200s with full glass cockpits.

I would also ask...do WOW air's A321ceos (or most of them) have extra fuel tanks on them?

And while on the subject of SQ, Singapore Airlines actually requested a higher MTOW on the A340-300 to fly to some European destinations too small for a 747, to replace the canceled MD-11 order which couldn't do missions such as to CDG, AMS, and MXP. Airbus bumped the A343 MTOW to 275t.

I think the first guy was right. The 707-138 was a shortened version of the 707-120 built for Qantas. It was like the 707 version of the 747SP.

Each successive Boeing Model has fewer customization. The 767 has a lot. For example, American took theirs without Flight Deck carpet and with a custom Altitude Alert system. Those kinds of things are not offered as much on the 777 and 787.

Are you referring to the rudder or the fairing between the bottom of the rudder and the #2 exhaust on the BWIA L1011 ?


Can’t imagine Lockheed would install a larger rudder for one customer.

I think the first guy was right. The 707-138 was a shortened version of the 707-120 built for Qantas. It was like the 707 version of the 747SP.

Qantas ended up being the only taker, but the original spec was for it to be the same length as the KC-135, i.e. 128 feet fuselage length. Pan Am and American successfully lobbied for the standard 100 to be 10 feet longer, which became the build standard. The article I quoted, as well as Robert Serling's book "Legend and Legacy" both corroborate this. What's really weird about it is that the 138, although the same length as the KC-135, has different proportions: the wing is one frame further aft in the 138 relative to the 135.

That's actually quite common for A319s especially in China (same goes to 73G). Quite a few airlines have these A320 engines installed to fly into high altitude airports since these airports require a higher engine performance to lift off the same amount of payload.

The UK ARB refused to certify the 707-436 bound for BOAC until modifications were made to improve engine out directional stability (ventral fin and powered rudder). For a brief time the BOAC 707's were unique (also Conway not P&W powered).

Boeing then rolled out the BOAC mod free of charge to other operators and the ARB mods provided a foundation to rectify the 707's woeful directional stability

If memory serves me, didn't BA also have a "Lite" version of the 744, with reduced MTOW and no crew rest?

One more. Dan-Air's 727-100's received UK certification only because a stick-shaker was installed at the request of DP Davies, the CAA's Chief Test Pilot (author of Handling the Big Jets). He discovered the deep stall tendency of the aircraft, which was known by Boeing but not fully explored or rectified. As Dan Air was the only UK 727-100 operator, this was a unique customer mod. Interestingly when the 727-200 was wanted by Dan Air, the CAA took a different route and relied on the 727-200 stall incident rate in sevice.The shaker was not put on the -200, much to Davies distain, and it was indeed removed from the -100's

A couple I can think of:

The Trident 1C was built at BEA's request.

ANA's 777-200s had a 6ft fuselage stretch.

* The Douglas DC-8-55 was made especially after a request from SAS

* The Douglas DC-8-62 was tailormade for SAS, wich was the launch customer, but it eventually was also sold to other Airlines

* The McDonnell Douglas DC-9-41 was made after SAS specifications and again SAS was the launch customer. It was eventully also ordered by one another airline: TOA Domestic

* McDonnell Douglas DC-9-21 especially made for SAS. The airline was the only operator of the variant.

* Airbus A300 B2-320 had a unique hybrid combination made for SAS.

* Not sure, but I think perhaps the Boeing 737-600 was made after SAS specifications. Atleast SAS was the laucn customer.

The now defunct Norwegian airline Busy Bee had a special Boeing 737-2R4C.

The aircraft was designed to be able to operate out from gravel runways and was also as the only 737 certified to be used for parachuting

Airbus modified the MLG on the A300B for Eastern, increasing the spacing between the wheel pairs to lower the ACN to allow operations into LGA.

Although not purely Airbus but Air New Zealand is having ATR develop and certify RNP navigation system for their ATR planes to increase operational reliability in and out of Queenstown (ZQN) airport. If I recall this should be completed development in 2018. I do know that this is being developed completely by request of Air New Zealand according to an information session they did in Queenstown a year and a half ago.

Each successive Boeing Model has fewer customization. The 767 has a lot. For example, American took theirs without Flight Deck carpet and with a custom Altitude Alert system. Those kinds of things are not offered as much on the 777 and 787.


Why did American not have carpet in their 767 flight deck and what was the custom altitude alert system?
Anyone who has never made a mistake has never tried anything new.

6ft stretch? I can't find anything about this anywhere - do you have any more evidence or information?

When Trans-Canada Air Lines was negotiating with Vickers Armstrongs for purchase of the Viscount, the cockpit design came under scrutiny. At the time, it was a three man crew. TCA and Vickers designed a two man crew, which became the export standard starting with the 724.

TCA did the same thing with the Vanguard. And while there were only two original purchasers of the Vanguard, BEA's had a three man crew while TCA's were two man. (A navigator was carried though when flying outer Caribbean flights).

TCA tried the same thing with the DC-8!!! Douglas was able to design the DC-8 cockpit with only two pilots. The F/O's seat was on rails that went back abeam the F/E's panel. Some gauges and controls were placed under the flying instruments on the Captain's and F/O's panel. Transport Canada (DOT at the time) though would not approve of such an arrangement.

However, construction had continued to a point that a lot of the cockpit controls could not be changed. As a result, all of the original TCA and Air Canada DC-8s had unique cockpits that made them difficult to sell when the time came. They only ever flew with 3 pilots though, or 4 when a navigator was carried.
Just because I stopped arguing, doesn't mean I think you are right. It just means I gave up!
