The Mercure has just been rolled-out
of the Bordeaur-Mérigr.rac
æ
factory only 23 rnonths after the green light on production. For Dassault, it is "not a cause for festivities, but a family affair, when
one of its aircraft is towed out ol the hangar by a tractor, and if any ol the few persons present were expecting a party, they must have been sorely disappointed. On the contrary, the event turned out to be a serious rvork session. Dasshult even scheduled the roll-out for
Sunday,
to avoid disturbing
the
regular development program, and as an additional guarantee ofprivacy.
Nevertheless, although the event waS in no \\'ay publicized, it was indeed an important date for Das-
sault Management.
First of all, because it showed o.nce argain, that program planning is a Dassault stron,epoint . Just as'the full size model rvas readv in time
lor the 1969 Air Shorv at Le Bourser. the Mercure 0l is right on time for its April l97l rendez-vous^ and there is every reason to expect that this ability for efficient research and production planning will be repeated in the luture: for the maiden flight, rvhich will be imminent, by the time these lines appear, and for certification, scheduled for the end of March i973. Aside fron-r the successful deadline performance, the April 1, l97l roll-out wAS inrportant in n)any other respects, .,rs many system checks rvere made, especially involving the hydraulic and electric systems.
The Auxiliary Power Unit reacted beautifully to testing (start-Llp, regulation, etc.), but it was perhaps its low noise level that proved the greatest source of satisfaction.
All
specialists present, agreed that the APU noise level was e\ceptionally low. This victory is the direct outcome of close teamrvork betrveen Garrett. FIAT and Dassault.

The direct approach
At
Dassault, customers deal with men, not with titles. Dassault does not want its customers to get tangled up in the red tape that impersonal offices and departments invariably create. Instead, problems are settled directly, with a real flesh and blood person, holding power of decision.
This method saves much time and effort. The man on the other side of the desk will not brush questions aside, or try to escape commitment, but will give a pertinent answer to any question... and right away!
Export oriented When setting-up its programs, Dassault has always kept an eye on the needs of other countries. In fact, exports account for nearly two thirds of the Company's total turn-
over figure. Dassault military aircraft are flown by 15 different countries, and civil aircraft have been sold to no less than 25 countries. The "Falcon 20" successfully won over the North
American market,
a
traditionally
hard nut to crack, for foreign contenders, and the 'oFalcon 10" is well on the way to collecting the same honors. But one of the underlying secrets of this success is that Dassault carefully
of its programs with an efficient service support organization that can guarantee implements each
availability to customers... long after the sale has been made. For the Mercure, Dassault is planning new support facilities, on a vast scale, tailored to the program itself. It is a fact, that although the first
Mercure prototype is now being groomed for its maiden flight, Dassault has been working quietly in the background, for over 4 years, to prepare the kind of service support that this aircraft deserves.

The importance of this aspect of aircraft management cannot be overestimated. Although it involves care-
fully planned activity which goes on quietly, behind the scenes, a smooth provisioning organization is essential for keeping an aircraft aloft.

an airline must have its own stock of spares on hand, for all forseeable repairs, as soon as its first aircraft enters service.

Aircraft availability has always been a special point of honor with Dassault. Dassault wants to see its aircraft in the sky, not grounded, because of repair problems.
Special arrangements have been made with carrier companies and customs authorities, to cut-down on red tape, and accelerate arrival
of the required part.

Aircraft familiarization courses will be organized for mechanics and flight personnel, at Istres, near Marseilles, where the production aircraft are to be assembled. This is also where customers will take possession of their Mercure. All instructors are highly qualified engineers or pilots, assigned by Dassault, the engine manufacturer

answer to a customer call for lightening support, Dassault can also send out emergency squads. This is the procedure in the case of technical investigations, appraisals, or far-reaching modifications to the aircraft.
At the last Air
Show,
in
1969,
Dassault exhibited full-scale models of two new aircraft : the Mercure and the Falcon 10. In only two years time, both these aircraîl have become realities. By the time the l97l Air Show opens its doors at Le Bourget, the Falcon l0 will have been flying for 6 months,
and the Mercure will have logged its maiden flight. Regular Show visitors will certainly
be impressed by Dassault's ability to turn ideas into reality so quickly, and perhaps even more, by the ease with which the Company has been able to move into the civil area.
It is largely due to the determination of each member of the Firm, that so much ground could be covered in only a few months. Happy landing at the Bourget Air Showl
