Birth of the Airbus Family: The A310

The Airbus A310 prototype takes flight on 3 April 1982.
In the days following the start of the 1973 Yom Kippur War in Middle East in October that year, the oil producing nations of the Middle East responded to American materiel support of Israel with an oil embargo that sparked a worldwide economic crisis as the price of oil abruptly shot upwards from $3/barrel to over $12/barrel in a short period of time. As a result, the airline industry worldwide embraced fuel efficiency as the new driver for future aircraft designs. While there were high-bypass ratio turbofans that powered the new widebody designs that were entering service (Boeing 747, Douglas DC-10, and Lockheed L-1011 Tristar), turbojets and low-bypass ratio turbofans were still commonplace in the short to medium-haul fleets worldwide. Many airlines indicated to the major manufacturers that there was a market need for a fuel-efficient aircraft in the 150-200 seat range over short to medium haul ranges. Of the big three manufacturers in the United States who dominated the world commercial airliner market, Boeing's plans were the most ambitious with the launch of not just one aircraft, but two aircraft with a common cockpit with the Boeing 757 and 767. It was in many ways the biggest gamble Boeing had ever undertaken, bigger than building the Dash 80 demonstrator that led to the 707 and even bigger than the launch of the 747 ten years earlier. News of Boeing's plans put pressure on Airbus Industrie to respond as all it had produced by that point was the A300. While there were a range of A300 variants with varying engines, payload and fuel capacities, they were all still essentially the same aircraft and hardly a family of aircraft. Two of the primary founders of Airbus and their heads, Roger Béteille (technical director) and Henri Ziegler (general manager), strongly believed that Airbus needed to emulate Boeing's strategy of building a whole family of different aircraft for different markets if the whole enterprise was to have a future beyond the A300. Boeing's idea for commonality with the 757 and 767 designs resonated with the Airbus team who was commonality among varied designs as a way of proving value to the airline customers, not to mention it would be a strong incentive for an Airbus customer to stay loyal to Airbus in the future.

Part of the problem Béteille and Ziegler faced was that most of the Airbus consortium partners saw the A300 as the end result of cooperation instead of the starting point for future cooperation. A lot of that was driven by the atmosphere of fiscal austerity of the 1970s in the wake of the 1973 oil crisis- Airbus' partner nations were hesitant of putting up more money into the venture, particularly when Airbus was still a bit player on the world market despite the success of the A300. In 1978, for example, Airbus delivered 15 aircraft, all of them A300s. That same year Boeing delivered 203 aircraft across three product lines- the 727, 737, and 747. In fact, it wouldn't be until 2003 that Airbus would deliver more aircraft in a single year than Boeing. When Boeing launched the 757 and 767 programs, they were also capitalizing on market vulnerabilities experienced by McDonnell Douglas and Lockheed in the wake of their trijet programs- Airbus wasn't really on Boeing's radar screen at the time. Despite the market effects on McDonnell Douglas and Lockheed, they were still delivering aircraft as well which were entering service on top of Boeing's numbers. You can imagine what a tall order it was for Béteille and Ziegler to convince the Airbus consortium partners that there was value and potential for the long haul beyond the A300 at a time when they were only building less than 5% of the world's commercial jetliners. It wasn't until mid-1975 that the board of Airbus Industrie endorsed the plan for a family of aircraft- and that endorsement is a testament to the persuasive powers of Roger Béteille and Henri Ziegler. In his book Close to the Sun: How Airbus Challenged America's Dominance of the Skies, author Stephen Aris calls that 1975 decision as the most critical decision in Airbus' history. If Airbus failed, then it was only one aircraft, the A300, that failed. But if they became successful, then that one aircraft wouldn't be enough. The leadership of Airbus Industrie by that point had proven themselves remarkably adept in getting the A300 into production and to market while balancing the interests of the partner nations in the consortium. 

Winning a Swissair order was a strategic priority for Airbus
With the backing of the consortium to expand the Airbus product line beyond the A300, the next task at hand was to determine the configuration of the new addition. The first iteration dated back to the oil crisis of 1973 when A300 sales were near dormant (only four A300s were delivered in 1974). In response to what was seen as an evolving market for something smaller than the A300, what was designated the B10 was a minimum-change variant of the A300 that had a shorter fuselage but the same wing and empennage as the larger aircraft. However, the B10 proposal created a significant amount of discord at all levels of Airbus as the consortium partners argued whether it was needed or not. Lufthansa in particular was keen for a smaller A300 derivative and this had gotten the support of Swissair. In those days, Swissair was one of those flagship customers every commercial airframe builder wanted as a customer. They were a tough customer known to be one of the most difficult airlines to negotiate with- but a Swissair order was badge of prestige for any commercial aircraft design and with Swissair now allying with Lufthansa on interest for a smaller A300 derivative, winning Swissair as a launch customer soon became one of Airbus' primary strategic goals. 

By the time the two airlines were briefed on the B10 proposal, Boeing was well on its way to launching the 757/767 program and compared to those aircraft, the B10 had no fans with either Lufthansa or Swissair. Their objections of the proposal stemmed from two points- the first one was that by the time of proposed service entry, the B10 design would be based on technology and a design that was at least a decade old and more importantly, it had a worse payload fraction than the A300. The payload fraction is one way of measuring an aircraft's efficiency- how much payload can it carry compared to its weight. Since the B10 design had a shorter fuselage married to the A300's wings, it had less passengers (therefore less revenue) to offset the costs of carrying a heavier wing structure. This is one of the reasons why shrinks of commercial airframes tend to not do well in the market- like the A318, 737-500, or 747SP, for example. If the B10 proposal was ever going to get off the drawing board, it needed a lighter wing and whole host of improvements over the A300 to win over the airlines who were being offered the latest in technology with the 757/767. In an unusual twist of history, the prospect of trans-Atlantic cooperation offered an potential answer to Airbus' dilemma. Why not combine Airbus' growing widebody fuselage expertise with the technology and industrial muscle of the United States? The first feelers on such an idea came from McDonnell Douglas in the spring of 1975 for a joint venture for a 200-seat design called the DC-X-200. McDonnell Douglas had long been considering a twin-engine version of the DC-10 and the DC-X-200 was the latest iteration along those lines. However, once discussions moved beyond engineering to management, the talks quickly collapsed. That summer another offer came from Boeing who thought there would be some synergies with the B10 proposal and the 767 program. Whether Boeing was serious or just trying to distract Airbus is still a source of debate to this day, but the proposal would have consisted of the A300-based fuselage and 767 wings and empennage. At the end of the day, however, Airbus lost interest as it became apparent that they would end up a Boeing subcontractor in the joint venture. 

Lufthansa was an early A300 customer who drove the design of the A310.
Still keen to win over Lufthansa and Swissair, Airbus decided to follow as Boeing had done with the 757/767 and go with a two-crew flight deck and CRT displays. That would prove to be a relatively easy step to take but it still provoked the ire of the pilots' unions of several European carriers. The need for a new wing, however proved to continue to be problematic. I had posted previously that it had taken the personal intervention of a German politician, Franz Josef Strauss, to fund the A300's wing development and construction by Hawker Siddeley as a result of the British government's withdrawal from the Airbus consortium. Hawker was still the center of the most advanced wing design work in Europe and was in the process of merging with several other entities to form British Aerospace (BAe). With British Aerospace being majority owned by the government, there was considerable anguish at Airbus as to whether or not BAe would participate in the B10 project given the British pull out of the Airbus consortium in 1969.  When Hawker elected to remain an Airbus participant despite the pullout, they had absorbed a portion of the costs of wing development. Now that Hawker was part of BAe, no one was sure that the new entity was willing to front such costs again for the B10 project. Airbus decided at that point to turn to its partners for a wing design- Aerospatiale and VFW-Fokker each submitted wing designs and Roger Béteille was sure that whoever was chosen, it would be the end of Airbus as the other partner would feel jilted. As it turned out, neither was chosen- the German design was aerodynamically superior but the French design was structurally superior. A joint-wing design center was established to combine their efforts and word of this got back to BAe quite quickly that their replacement was in the works. 

The exact political machinations in the UK that resulted will be the subject of a future blog article, but they were contentious with pro-Airbus factions in the British government and those who favored a joint-venture with Boeing on the 757. At the end of the day, however, BAe did end up designing and fabricating the wing which was not only lighter, but was of supercritical section which made it not only more aerodynamically efficient but also offset the smaller size with a deeper airfoil section which offered more fuel capacity. Getting the wing also meant that the British eventually rejoined the Airbus consortium with a 20% share. On 9 June 1978, Lufthansa and Swissair issued a joint specification for the new aircraft and within a month announced intentions of placing orders for what was launched as the Airbus A310. On 15 March 1979, Swissair announced its launch order for 10 aircraft and 10 options with plans to use the A310 as a replacement for its legacy DC-9 fleet on its major intra-European routes. Lufthansa quickly followed with an order for 10 aircraft and soon after Air France and Iberia also placed orders, assuring the production and success of the A310. When the A310 prototype flew, it would later wear Swissair's colors on the right side and Lufthansa's colors on the left side. Many of the advances of the A310 were later incorporated into an upgrade of the A300, the A300-600.

The Early Days of Airbus Industrie and How the A300 Got Its Name


Roger Béteille, father of Airbus Industrie
The roots of the formation of Airbus Industrie are tied more to the abilities of one man more than any other individual in the early history of the Airbus consortium- Roger Béteille. A graduate of the prestigious École Polytechnique, he was the technical director of Sud-Aviation in the mid-1960s. Sud-Aviation produced the Caravelle and it was Béteille who was the director of the jet's flight test program. In postwar Europe prior to the formation of Airbus, the Caravelle was only one of two commercial aircraft programs to make money (the other being the BAC One-Eleven). He also worked closely with Hawker Siddeley on the Concorde program- this was an experience that unique among the French technocrats of the time, gave him a close working relationship and mutual respect of the British aerospace establishment. In the aerospace industry of France in those days, someone of Béteille's skills was unique given his flawless English, the respect afforded by the British engineering staff at Hawker, and his political skills in working with several European nations in the course of his career at Sud-Aviation. 

In the summer of 1966 there were three proposed commercial aviation projects that were commanding the attention of the European industry. The first one was the BAC Two-Eleven, a successor to the successful BAC One-Eleven. That summer BAC was riding high on the success of the One-Eleven which at the time was one of Britain's most successful and profitable aerospace programs. But it was already facing significant competition from the Douglas DC-9 and the Boeing 737 and BAC had been lobbying the British government for support to launch the Two-Eleven which would have been powered by a new engine Rolls-Royce was developing, the RB.211, that would also go to the Lockheed Tristar. The Two-Eleven was a larger development of the One-Eleven that for the most part, was intended to get British European Airways (BEA) to drop its interest in the Boeing 727-200. The problem with BAC was that it was heavily committed to the Concorde program and had little financial resources to devote to the further developing the Two-Eleven which is why they were keen on approximately $100 million in launch funding from the British government. 

Hawker-Breguet-Nord HBN 100
In the previous year (1965), the head of Breguet Aviation, Henri Ziegler (who later became Airbus's first president) had inked an agreement with fellow French firm Nord Aviation and Hawker Siddeley in the UK to jointly work on a widebody twin called the HBN 100 that was largely the product of Hawker's engineers at their Hatfield facility. The HBN 100 was to have two variants, one with a passenger capacity for 225 and a stretched one with a capacity for 260. The planned engines were to be either the Pratt & Whitney JT9D that was under development at the time for the Boeing 747 or the Rolls Royce RB.178 which was a three-shaft demonstrator engine called the "Super Conway" that eventually led to the RB.211. At the same time as the HBN 100, Sud-Aviation (Roger Béteille's firm) was working the Galion which was very similar in layout, appearance and size to the HBN 100. The Sud-Aviation Galion evolved from what had started out as an enlarged Caravelle. 

Sud Aviation Galion
In 1966 Béteille invited his friends from Hawker Siddeley to Sud Aviation's facility in Toulouse to see if the design work on the HBN 100 and the Galion might be aligned towards a common joint project. That invitation for Arthur Howes, who headed the Hawker team, to come to Toulouse is what gave birth to the Airbus. It soon become a joint program with engineers from all the involved companies shuttling down to Toulouse as needed as the designs of the Galion and the HBN 100 were more closely aligned. That December at a meeting in London, France, Great Britain, and West Germany- I'll soon get to how the Germans entered the picture- decided that a single consortium would build a widebody twin. At time time, Concorde had two production lines- one in France and one in the UK, and on top of the financial costs of the program, the duplication of effort was something Roger Béteille wished to avoid so that an attractively priced aircraft could be offered to the world's airlines. It was agreed that in exchange for Rolls Royce developing a new engine for their design, the Sud Aviation Galion would form the baseline design to work from with the HBN 100 being sidelined. 

It was obvious at the time that any joint effort would be spearheaded by Britain and France, the only Western European nations at the time that had the industrial capacity for large commercial aircraft design and production. But the West Germans were keeping an eye on the developments and the use of the name "Airbus" in reference to the nascent project actually came from them. Even though it was twenty years after the end of World War II, the German aircraft industry was still in shambles. Many legendary names like Messerschmitt and Dornier were still around, but even those entities were hollow shells of their former selves. What engineering staff hadn't left Germany after the war debated the future of their industry and decided the future lay in collaboration on a civil aircraft project. The year before Roger Béteille invited the British to meet in Toulouse, seven German aircraft companies (ATG Siebelwerke, Bolkow, Dornier, Flugzeug-union Sud, Hamburger Flugzeugbau, Messerschimitt and VFW) formed Studiengruppe Airbus (the Airbus Study Group) to determine what sort of aircraft the future airline market would need. It was this grouping of German companies that contributed the Airbus name to the young enterprise. It was at the following year's Farnborough Air Show that German participation was formalized. Up to that point, the Germans had been working on their own but it was decided that what the French and British had come up with baselined off the Sud Aviation Galion was a suitable candidate for their contribution to the effort. Officially becoming Airbus, each nation decided that one company from each nation would take the lead for that nation's contribution. Hawker Siddeley would lead the British contribution, Sud Aviation would lead the French contribution and the German Airbus Study Group was reorganized into a formal consortium of their own, Airbus AG, to lead the German contribution. 

But what to name this aircraft? Arthur Howes of Hawker Siddeley was partial to the name "Obelix" which was the giant in the Asterix series of comic books popular in those days. It was apparent, though, that the name had to be something that was essentially neutral to British, French and German interests. One evening at a dinner in Sud Aviation's Paris headquarters the upper level of management at Sud Aviation asked why a name for the aircraft hadn't been found yet. Different ideas were punted about before Howes himself spoke up as a joke and said "I propose we call it the HSA 300" and the room laughed as "HSA" was the initials of Hawker Siddeley Aviation. But Howes continued "H- Hawker Siddeley, S- Sud Aviation, A- Airbus, and 300 because it's a nice round number." As everyone enjoyed Howes' joke, it suddenly donned on him- why don't we call it the A300? 300 is still a nice round number closest to the proposed design's seating capacity and if "A" was used, the aircraft would always appear before Boeing in any alphabetical listing. Howes idea proved popular and the nascent enterprise's new design would be marketed as the Airbus A300.
