The Boeing 717
I
Monitoring has its origin in the DC-9, MD-80 and MD-90, Boeing 717, who had been appointed inceptionally the MD-95 the last plane had been purely "McDonnell-Douglas and the first and only transferred to Boeing for the continuous production.
Designed as an advanced, low-wing aircraft of 100 passengers with two aft-mounted, high-bypass ratio turbofans and a t-tail relies most on the MD-90, his immediate predecessor, design, intended for high frequency routes short and medium range, however, they had incorporated the development history of 40 years of his family for generations above. Having carried the three names of manufacturers of Douglas, McDonnell-Douglas and Boeing, the basic airframe was offered three major, three-motor nuclei the Pratt and Whitney JT8D, the International Aero Engine V2500, and BMW Rolls Royce BR715, a broad range of capabilities of thrust, from 12,000 to 25,000 pounds four denominations base DC-9, MD-80, MD-90, and MD-95/717, passenger capacity ranging between 90 and 180 under a single class, and eight lengths of fuselage as the DC-9- 10, the DC-9-30 the DC-9-40, DC-9-50, MD-80 MD-87 MD-90, and 717 of the.
Intended as a new generation of DC-9-30 replacement, the most popular numerical DC-9 with the 662 version have been sold, the initially-designated MD-95 has a total length of 124 feet, which is 1.7 feet shorter than the DC-9-40, allowing complement of 106 passengers in a four abreast, two-two, first-class cabin in a seat pitch of 36 inches and a current of five, two and three years, the economy cabin, a seat pitch of 32 inches. One hundred and seventeen, alternatively, can be accommodated in a single class, setting five a day. Two facilitate hold baggage, cargo and mail storage.
The state of the art, two cabin is equipped with six interchangeable liquid crystal display (LCD) units, an electronic instrument system (EIS), a dual management system (FMS), a control fault display system (CFDs) and advanced Honeywell VIA 2000 computer, and is capable of Category III landings, with the possibility of lower IIIB operations minimum.
Its all-metal wing two mast, like the earlier DC-9, MD-80 and MD-90, has the full period of two positions in five main sections edge slats, spoilers of two sections, three-section, double slot, trailing edge flaps, and manually operated ailerons operated wired differently in flight to the bench and the nominal control. The wings with a period of 93.4 feet, are sweptback 24 degrees for a maximum of Mach 0.82.
The t-tail, located well above the engines, the engine thrust eliminates interference with horizontal surfaces, which are connected by cable lifts and manually operated, while the vertical stabilizer rudder hydraulic is diverted to fly-by-wire cutting. The MD-95/717 's tail surfaces thick skins that use of any of the last MD-80 or MD-90.
Propelled two aft-mounted engines, BMW Rolls Royce BR715-A1-30 high bypass ratio turbofans, each rated at 18,500 pounds of thrust, the aircraft fully free installation of equipment in its wings, wing creates maximum lift for optimum performance. Based on single-core BR700 The BR715 has one of two-stage high pressure turbine, a fan chamber 58 inches; single crystal turbine blades, the largest combination blade and disk (blisk) ever the service of a commercial power plant, and is equipped with reverse thrust. The 19-foot long, 6155 lbs engine, the third basic type have powered the DC-9 family had been first on 28 April 1997, reaching nearly 26,000 pounds of thrust at this time. MD-95 is the single-engine.
The plane sits in tricycle landing gear on two-wheel-driven equipment.
order to launch initially appointed MD-95-30, consisting of 50 firm orders and 50 options had been placed on 19 October 1995 ValuJet, a DC-9 and MD-80 operators, and the prototype, a former Eastern Airlines DC-9-30 MD-95 modified for standard and registered N717XA, was released three years later, on June 10, 1998, first taking its first flight on 02 September. The plane, which reflects the acquisition preceding year of Boeing and McDonnell-Douglas scheme of 7-Dash-7 number, had been renamed "717", the common nomenclature own Boeing Stratotanker KC-135A, the military derivative of the 707.
The first production aircraft, registered N717XD, was first rolled out in January 23, 1999, and the guy had received joint certification from the FAA and the JAA nine months later, on September 01 after a flight test program of 2,000 hours which means 1900 outputs individual and fuselages of five years.
The first aircraft, N942AT, had surrendered to the new brand of AirTran Airways, so far a 737 operator that ValuJet intermittently had acquired on 23 September, and was inaugurated into service next month in Atlanta-Washington route.
The 717-200, the version first and only time, had offered with options for weight loss, the gross primary and secondary. The first, to 110,000 pounds, has an extensive nautical miles with a capacity 1430 of 24 609 U.S. of fuel per gallon, while the second, to 121,000 pounds, has a wide-2060 nautical miles with a capacity of 29,500 U.S. gallons of fuel, but reduces the space under the floor because of the additional tanks and requires updated 21.0000 pounds of thrust-BR715-C1-30 engine.
The plane of the maximum altitude certificates is 37,000 feet.

A flight triangular, tri-partite with AirTran Airways, from New York / LaGuardia to Akron, Ohio, Atlanta, Georgia, and back to New York, is indicative of the mission for which the 717 had been designed.
Following a Canadair and Embraer brigade "mini-jets" but reflects the long fuselage "big brother" American MD-82 and identical in Atlanta, AirTran 717-200 bound immediately ahead of it, the 717, which operates Flight 202 and registered as N926AT, crossed the track of arrivals, 4-22, before maneuvering to strip out the track 13. lightly loaded, with only 20 passengers on board, the two motors, T-tailed aircraft lifted its main wheels and trim the concrete itself a steep angle, initial climb, putting in its tricycle landing gear at 55 degrees, the spring air.
Overcoming geometries Queens home and close the gap to the opaque film location paper thin cloud, the flight 202 banked left aware of the Throgs Neck Bridge on the deep blue of Flushing Bay. Oppress up power, stationed to the left.
Island Manhattan, which appear beyond the left corner as a thumbnail and as floating between the Hudson and East rivers, successful projects its tall buildings, needle, into and through the low mist hangs on the ground as bastions of architectural victorious war of man. Beyond the Verrazano-Narrows Bridge, gateway to the Atlantic, the sun turned the water into a glass reflection of copper.
Now assuming a shallow angle of climb barely perceptible, the 717, the last evolution of the DC-9, crossed the eastern bank of the Allegheny Mountains, which appeared as black, charcoal-sketched below 35,000 feet waves.
Aided by the bare-faced, upper wing surface panels speed brake, twin-engine plane began a shallow descent about 40 minutes later under dirty white and gray cloud layers to January-indicative patterns of the farm in eastern Ohio, knocking over light chop.
Perpendicular runways the Akron-Canton Airport before it moved forward and to the left. Spreading its leading edge slats, which produced significant drift, the train completed its flight 202 trailing edge landing and sequencing of the flap, arcing in a bank-final approach course left. touching the bare, brown tree-lined farm patch engine settings offset drag, the 717-200 burned beyond the runway threshold and sideslipped in rough contact, crosswinds.
Shooting beyond the circular, brick Akron-Canton Terminal, in which four of United Express, U.S. Airways Express, Delta Connection and ERJ-135s and CRJ-200 had nose the plane, the largest in the ramp, starved its fuel aft mounted engines, which go down into silence tail replaced by the ringing of jetbridge extends to the future, the passenger left door.
Away from the door in 1215, 717 of AirTran, which now operates nonstop to Atlanta as Flight 202 began its taxi without obstacles in the Akron-Canton Regional Airport and was immediately taken clearance on the track 19. The deactivation of the same land, on the plane, a passenger important addition, retracted its landing gear with a light thud and climbed along the Ohio patchwork of agricultural land, which later gave the rolling hills. With altitude, these have been reduced completely to the dark indistinguishable.
Leaving white cloud covering on the undulating green West Virginia and Kentucky to 37,000 feet, the twin-engine T-tail plane parallel to the line of cottony nimbus which was attached along the east coast.
The chocolate brown ridges of the Great Smoky Mountains of North Carolina crested waves that had been frozen solid in their bills and had to descend back to Tues
The dorsal surface of the wing speed brakes 717 induced a rapid decline over Georgia into the swollen banks of snow white clusters, bullet nose through the darkness that surrounds boring as a missile penetration. Banking on its longitudinal axis planes began a series of separate arrival s-turn, swayed by the disturbing air of associated clouds, whereas the gas-maneuvers resulted in a series of periodic oscillations speed: airspeed as peeling, the engines were significantly queue, followed by a deterioration rate of speed, before the process was repeated.
The aircraft left the cloud of islands on a blanket of Georgia green and brown earth. The skyscrapers of Atlanta, but still in the form of miniature rose the view in front of the left.
Expansion of its tricycle landing gear in the wake and increase the camber of the wings' upper surface and the area of its maximum with full, final voyage external cover, the 717 made a left bank to the final runway 28 in the pure blue sky dotted with 68-degree suspension lint cotton candy. Parallel to the left, a 757-200 and a Delta ASA CRJ-100 is about 27 tracks left and right-tailed t-pure rush of crossing the threshold, the print queue for their engines for a final time, which profiles for a flare, and crouched on the concrete with its main landing gear "hind legs", which absorbs the least contact with the protest.
The return flight, operating non-stop, occurred before the night.
A flood of light points, representing the final approach to Hartsfield-Jackson Atlanta International Airport that dark January night, seemed to vie in competitive speed, for 27 tracks left and right ", at the AirTran 717-200, operating as flight 343, Gate C-12 to New York-La Guardia, now rolling. On the threshold of the right of the two parallel bands, is strangled in a roll acceleration pinnacling engine and swung in a corner of the nose high and their horizontal stabilizers, release generated enough to lift soil and submerged in Georgia surrounding low-lying clouds.
Its retractable landing gear, itself the dark hall. Thin, horizontal layers of fog made the background lights orange, an ethereal blur, an attempt to silence, only partial success to penetrate the veil of the "other side."
Departing of civilization, the twin engine sat in his independent plateau, 35,000 feet high, which could see but not touch the world in miniature below. Threading it to the East Coast, flying over Greenville / Spartanburg, South Carolina, Greensboro, North Carolina, and Richmond, Virginia, represented by their respective stains light background, "Spill" iridescent paint had been thrown into the land of black canvas without form or foresight.
Routed according with its flight plan, east of Washington and Philadelphia, Flight 343, an autonomous, enlightened the world pursuing his track invisible in the darkness of January, followed by the coast of New Jersey.
Leading edge slat extensions, allowing speed to purge, took place 40 miles from the airport. La Guardia approaches to runway 22, take the plane to the north before he could give a final lap.
Momentarily stuck in the black, referenceless gap between the High Bay New York and the night sky, the plane went right over the small Statue of Liberty and lighting, sculptures shining jewel of the island of Manhattan, from which the field of the track perpendicular to a rolling pattern of La Guardia.
Then, in the precision, the pattern of aircraft approach lights, the 717 banked left on the black reflective surface of Long Island Sound beyond the pale green collar hanging from the Throgs Neck and Whitestone Bridges.
Execution an approach to long end of the coast of Connecticut, a 132-knot speed, the twin engine broke its landing gear, and extracted the last amount of lift can get their wings swept fully behind the flap edge extensions, a move that created so much drag contradictory as it did lift and only truly offset by increased power.
Leaning Wash Bay, with its nose, it passed over the pier support runway 22 threshold and vanishes in the wind face, concrete re-booting with the main wheels and unleash their spoilers and thrust reversers in a simultaneous explosion. An American 737-800, that had preceded landing, had just turned to the parallel taxiway.

On May 23, 2006, during a ceremony attended by thousands, Boeing had shot the last two 717 sorted by Midwest and AirTran Airways, which marks the final delivery of the design, the end of the McDonnell Douglas aircraft, commercial and closure of its plant historical production of Long Beach.
Founded by Dr. Donald W. Douglas, the Douglas Aircraft Company had flown his first plane, the Cloudster "" in 1921, and had opened its Long Beach plant in 1941, on the eve of World War II, when demand had eclipsed the existing capacity of its Santa Monica and El Segundo, California, plant. The first commercial design Douglas, the DC-1, had been built and sold to Transcontinental and Western Air (TWA), becoming the precursor of a long line of increasingly advanced aircraft piston which had introduced the world to commercial flights.
The merger with the company McDonnell in 1967, the Douglas Aircraft Company had been renamed McDonnell-Douglas, their products which includes the commercial division of the new corporation, and 30 years later when Boeing had acquired McDonnell-Douglas, had become the Douglas Products Division. Ultimately, had been appointed to the Division of Long Beach of Boeing Commercial Airplanes.
During its history of more than 65 years, the Long Beach plant had produced about 10,000 military aircraft during the Second World War and 15,000 commercial and military aircraft, global design, while more than 65,000 airframes were produced by all of its locations.
Despite more efficient and profitable techniques final assembly developed by Boeing, the 717 had not been able to maintain its competitiveness, in part due to conflicts sales with its own 737-600. However, 156 717 produced, together with the previous generation 976 DC-9s, MD 1191 80 and 114 MD-90, had already almost half a century robust service, reliable and affordable worldwide, and seemed likely to do so for many years to come.
