The Boeing 757

I

Increased demand on existing roads Boeing 727, often eclipsed the capacity of even the secular version, -200 Series, as the technology dictated the need for which is a variant of the venerable three-jet or a completely new design.

The first attempt, by adopting the above approach, offered a fuselage large enough to accommodate 189 passengers and three refanned greater capacity Pratt & Whitney JT8D-217 engines each developing 20,000 pounds of thrust. Designated by the 727-300B, which first appeared in the 1975 Paris Air Show as that model. Despite the initial interest in United Airlines, the company saw the need for more quiet, power the most advanced.

A radical overhaul, keeping the nose of 727, the forward fuselage, and T-tail, and designated "7N7", a new section of the fuselage and a wing of the new technology, cross, much smaller 737, two engines mounted on the tower, including Pratt & Whitney JT10D-4, Rolls Royce RB.211-535, and General Electric CF6-32 was then considered. Although expected, like its counterpart inceptional for one-stop sectors Transcontinental contained sufficient volume of fuel tank wing and, finally, long-term deployment.

Because the comfort of widebody has been well received by passengers on intercontinental routes, iteration had explored briefly increased the fuselage cross-section of twin-aisle 180-passenger reception. The concept has served two purposes: 1). Should offer more convenience, and hence be more competitive with the then outstanding A-300 Airbus Industrie on industries relatively short domestic USA, and 2). Would have avoided the excessively long fuselage needed to meet any increased capacity in the future, eliminating the requirement for Landing Gear Struts longer sufficient to maintain the angles of rotation at takeoff.

The width provided, however, was too a reward for these benefits, as shown in the interest of small aircraft because weight and resistance associated with a second row and only one seat was both impractical and his section, much larger than the 7N7 was too narrow to accept the standard LD-3 containers baggage and cargo.

Returning to his studies of narrow-body Boeing has proposed an advanced section 727 of large capacity, in February 1978, had offered his nose, cockpit and fuselage, but introduced a new wing and two turboprops complement of 170 passengers, using much of the community develop simultaneously, two lanes 7X7 design. Renamed "757", which would be the fifth line of Boeing commercial aircraft, leading to lead the seven-dash model of seven numbers in order after the 707, 727, 737 and 747, all except the last which was narrow body.

In comparison with 727 that had been intended to replace, had offered a lower consumption of 15 percent fuel, however, its surface Wing inherently promoted significant weight, reach and increases the ability of all future derivatives.

To reduce development costs associated with their 767, the jumbo jet, the twin-aisle, twin-engine counterpart originally intended also to a one-stop intercontinental routes, Boeing, where is possible, incorporated in common that both types of aircraft and the two share the same sections of the nose in front, the windshield, four main wheel landing a gear, avionics systems and flight deck. In fact, the two planes, forming a new generation of advanced twin engine narrow and widebody aircraft, provide a common type rating, increasing the mixed fleet flying companies operating both types, and even initially planned 727-T-style tail was removed for the 767 classic, low-wing configuration at the end of the design phase, resulting greater consistency with 767 of 727, which are intended to replace.

Launch orders for 21 firm and 24 options and 18 firms and 19 options, respectively, were placed by Eastern Airlines and British Airways, August 13, 1978, Rolls Royce RB.211-535C-powered aircraft. Offering a capacity of 196 passengers within six per day, 34-seat configuration inches in height, the 757, with 220,000 pounds of gross weight, is optimized for 2000 nm sector, while an optional £ 230,000 weight increase the range of 2,500 miles.

Reductions in structural mass, which lowered the seat-mile were made with the construction Peak and consists of an aluminum alloy, the first plastic composite reinforced with carbon fiber used in the engine cowlings, flaps, spoilers, elevators and rudder, and reinforced Kevlar, plastics used in the engine cowl and around the fin and stabilizer tip fairing. Copper and zinc alloys, aluminum has been used in skin-wing, spars, and lower beams Spar. The alloy, providing a strength increased from five to 13 per cent, in combination with compounds, weight reduction in the structure and £ 2000 has resulted in an average fuel economy per year per unit of 30,000 U.S. gallons based on a utilization rate for 1400 of 1,000 nautical miles sectors.

The aircraft in its initial version, 757-200, presented a total length of 155.3 meters.

The alloy of aluminum, two spar wing, including the section Permanent Central through the fuselage, offered a period of 124.10 meters, an area of 1994 square meters, and five per cent of dihedral, and shared a high degree coincidence with the 767 he designed for his profile back-loaded drag rise Mach delay. But it was thinner in its enclosure with the root of the fuselage and offered 25 versus 32.5 per cent of the arrow. Its strength has always been offset by the increase of their mission profiles expected that Because of their short duration implies higher rates of rise and decline cycles. He had a ratio of 7.82 point, or the ratio of length and width.

Elevator was increased by five full-section slats and double slotted flaps behind the tip, while the roll control was provided by Al-speed lateral fins themselves assisted by five-fold section. They could be deployed in the alternative flight or a dump truck airbrakes on the ground where the two panels Interior spoiler could also be used.

Power pole provided by two propellers mounted high ratio of diversion to the bottom edge of the wing, and the diameter would not have been possible with the 727 rear fuselage facility agreement, resulted in flexion of relief.

The Rolls Royce RB.211-535C, the shortened version of the range of 42,000 pounds thrust RB.211-22B developed for the Lockheed L-1011, compounds pod construction worker to reduce weight and the 757 was first published on January 23, 1982. The three axles, 37.400 pounds of thrust engine was chosen by the launch customer Eastern and British Airways.

The RB.211 535E4 advanced, incorporating fan blades variety of agreements, the high pressures increase the exhaust module and a common for the fan and the general public, offers a reduction of eight per cent of fuel in cruise mode and has increased by four point pressure ratio of 23:1 to 27:1, on its previous version-535C. 40.100 pounds of thrust engine was certified November 30, 1983 and the first flight of the 757 in February next.

The Pratt & Whitney PW2037, as specified by American Airlines and Delta, was the second plane, and one other powertrain. JT10D initially appointed, the two shaft turbofan inceptionally designed as an engine thrust £ 26,700 when the program began in February 1972, had become the trend of 37,000 books, including the double-flow high pressure compressor efficiency has been improved with a small compressor, with speeds higher rotational basis. First prototype flight in 757, in March 1984, certified that 37,600 pounds of thrust at takeoff and had a bypass ratio of 5.8:1. The production version providing a capacity of 38.200 pounds of thrust, while the gross weight of the lead plane, otherwise, could be powered by £ 41,700 to PW2040s thrust.

Fuel was carried in two wing tanks full and a central part, with the one stored in external tanks burned past to maintain the reduction of bending of the wing. The capacity was 11.253 gallons U.S..

The conventional stabilizer wing low, adopted late in the development of the Boeing 757 program, gave a reduction of the total length of 18 feet, however, resulted in a longer cabin than the 727 it replaces and improves the soil treatment. The variable incidence tail horizontal equipped, fully built in arch, two cans of light alloy, has an area of 542 square feet, while the vertical structure consisting of three mast cell double lightbox pair alloy, covered 370 square feet.

The tricycle landing gear is a double wheel, front leg retraction and two to four wheel discs shrink laterally compound Dunlop Goodrich or wheels, carbon brakes and tires.

The crew standard cabin included two of the operation and the observer's seat while the cab, 118.5 meters long, 11.7 meters wide and two meters tall, wearing a look with large wide-body, Kevlar, individually sealed compartments, overhead storage, a carved ceiling, recessed, hand shape, and the seats is not fattening. Cooking, cleaning, clothing and the number and location varies depending on customer preference, but can be installed at the front and the back or middle.

Great class, tone and density distribution of seats, depending on customer choice were available. A 178 passengers to fill out, for example, covers 16 seats in first class four day, two and two, in a configuration of 38 inches and 162 economy class seats on a six-day, three and three, an agreement for the 34-inch pitch,, While 208 passengers could be accommodated in a top 12 class and 196 economy class configuration, the last in a field of 32 inches. single class of high density, and included visits / densities Charter, at least 29 inches of rotation, included 214, 220, 234 and 239 passengers, it is superior to 727-200 maximum of 50 passengers and undermine 767-200 WideBody equal numbers.

Access to the cabin was provided by one of three service doors lead / and two exits on the wings of each side or above four passenger doors and service sides.

The two cargo holds, access to starboard, under the doors of the bridge, which offers 700 cubic feet of space at the front and 1090 cubic meters to the rear.

Boeing 757 engine systems including Honeywell-Vickers Pumps hydraulic and hydropower ABEX four bombs. An Allied-Signal GTCP331-200 auxiliary power unit (APU) provides Ground Power for air conditioning, lighting and the engine starts.

The approval of a comprehensive program was received in March 1979 and end the Assembly, as all previous Narrow-body aircraft, occurred in Renton, Washington, with the first metal cut for December 10 and the Assembly first major place 13 months later, in January 1981.

First deployment, January 13, 1982, five months after its widebody 767 return and take the plane to first time February 19, 757-200 prototype (N757A) was driven by pilot John Armstrong and propelled by £ 37,400 of RB.211 thrust turbofan 535C, complete the hours, outlet opening 31 minutes, during which he had reached 250 knots indicated airspeed (IAS), before landing at Paine Field Boeing 'Flight Test Center in Everett. Despite having introduced the first CRT display device equipped crew of two, was the first Boeing has started drawing a type of foreign motor proved easy handling characteristics.

The five devices in the test program flight finally revealed that, compared to 1979 the original design specifications, which had a weight of less than £ 3,650 for operating a 200-mile Boat carrying capacity above and burned three percent less fuel.

Certified by the FAA December 21, 1982, the 757-200, Boeing longer single-aisle twin engine, entered regular passenger service with Eastern Airlines on January 1 following in Atlanta to Tampa and Atlanta, roads Miami, while British Airways, the configuration of their first 12 aircraft and 174 seats in economy class, has taken delivery of such January 25 and was inaugurated in service February 9, London-Heathrow and Belfast, Northern Ireland.

The Pratt & Whitney PW2037 variant of the first power, the first flight March 14, 1984 have been delivered to the launch of Delta Air Lines customers seven months later, in October, the month when it was his first example of improved engine, equipped with RB .211-535E4.

So aircraft engines, with 186 mixed-class passengers, had a maximum of 220,000 pounds and a weight maximum gross £ 198,000 settlement, which offers a match of the 2820 mile range capability, although the midrange versions had a £ 230,000 Weight classification of examples of a long movement of gross weight of 250,000 pounds, in which case 3820 miles sectors could be blown.

Although maturation DC-9, 727, and 737 roads conceptionally had dictated the need for the 757, its gross weight and therefore increases the capacity range, allowing him more time, and trans - deploy intercontinental sector, partly in reaction to rising fuel prices, and is used often, if not replaced, 767-200 services, in addition, before to usurp its dual counterpart aisle. Delta and Eastern, for example, operated segments Transcontinental consolidated its Atlanta, while this pattern imitated USAir in Los Angeles and San Francisco from its base in Pittsburgh similar flight. Ladeco operated service Intercontinental Santiago, Chile, Miami and New York, and Canada 3000, Icelandair and Air 2000, all scheduled and charter operates transatlantic services. The type that occur between Tel Aviv and many of its destinations European.

Apart from the initial version of 757-200 passengers, Boeing has offered a number using sub-variants of the same length fuselage and wings, although these products are sold in limited quantities.

The first of these, the 757-200pF Package Freighter, was developed for United Parcel Service (UPS) while 20 companies had placed orders and 15 options for the Pratt & Whitney PW2037-Powered Aircraft December 31, 1985. These Featured a 134 - by 86-inch upwards, opening the hydraulically operated main gate of the station before the cargo, left, a smaller, 22 - by 55-inch door crew access, cargo systems, a solid barrier, sliding doors installed between the cabin and the main deck Bay office, and removal of all passengers from the windows, kitchens and toilets. First delivery for UPS September 16, 1987, the twin-engine, with £ 240,000 maximum weight loss, gave 6680 cubic feet to cubic meters in 1830 and principal of the lower deck, which allows up 15 pallets to be carried into space for the passenger before.

A modified version, the 757-200M Combi passenger facilities selected the -200 and the elements of loading and loading of 200pF, which allows three pallets and 150 passengers at a time housed in the main bridge. Although been available with 250,000 pounds of high gross weight, one in the case had been ordered by the Royal Nepal Airlines.

A conversion program developed by Pemco Aeroplex in 1992 allowed companies to change the passengers of the plane begins to merge, change fast, or all variations of the load, with a capacity of 11.276 gallons of U.S. fuel and the weight-200pF.

The only military version, the C-32A was ordered by the Air Force the U.S. to replace their thirst for fuel, outdated, four VC-137S engine, and had offered a 45-passenger interior. Renton first flight on 11 February 1998, the aircraft, ultimately, a fleet comprising four had been operated by the 89th Airlift Wing at Andrews Air Force Base in Maryland.

One representative, 757-200 transatlantic flight, operated by Icelandair from New York-JFK to Reykjavik, Iceland, forthcomingly shown.

The aircraft scheduled to operate daily, leaving the night Iceland, registered TI-FIH, was expelled £ 40,100 of thrust RB.211 535E4 Rolls Royce turboprops configured for 22 and four per day, two by two, Saga business class, with wings and footrests equipped with six seats, and 167 per day, three and three seats in economy class, covered with soft upholstery, blue. The 250,000 pounds, high aircraft gross weight, with an average capacity load of 8800 pounds, offers a range of 3,900 miles.

A rear door 21 of the existing building, JFK International Arrivals per day in 2050 a massive Korean Air 747-400 after a sweltering 90 degrees, early summer the blue-trimmed, long fuselage 757-200, in a manner reminiscent of the DC-8-63S has been replaced, but with only half the number of power plants, it was an autonomous entity after disconnection of the couplings in the dark dark highlighted by the glow of the location of clouds on the western horizon.

The two people, clocks cabin technology transition include both traditional analog and six advanced cathode ray tube (CRT) The first consists an airspeed indicator, altimeter, vertical speed indicator, a clock, and the flight instruments of relief, while the second part of the system of instruments electronic flight (EFIS), electronic two attitudes and direction indicator (EADI), and two indications of engine and crew alert system (EICAS) it is in the central panel. The electronic flight instruments, grouped in the attitude director indicator (ADI) and the position indicator horizontal (HIS), the attitude of the aircraft provided and positioning information through the CRT in seven colors.

Director Indicator Trim specifically provided aircraft attitude and tone, and census data, and ground speed, autopilot, auto-throttle and the means to fight against the management, operation over the horizontal situation indicator, which was monitored by aircraft, speed and wind direction, the lateral and vertical variations, and reference to normal and could be used in four basic modes. The map display, the first weather radar returns generated at different scales, while the VOR mode whenever the relative position of the selected courses VOR the aircraft. Airplanes SLI mode over a relationship with the ILS Localizer and glide path, and how to plan, the last of four shows the part desired flight plan with north at the top of the screen.

Stabilizer leverage eight degrees, the nose wheel rotation to emerge, 757 separated from the concrete with its current generation of lift of the wings, retractable landing gear his tricycle, and participation of its mode of vertical launch since climbed to 200 feet by 175 nodes, 15-degree position.

The speed of temperature exhaust gas and a fan, respectively, recorded 157 and 917.

Continuing its standard instrument departure (SID), the wing plane shook head on a bench on the left on Belt Parkway at dusk, topping the gold, green, orange, and the patch of white light, like painting Iridescent versa on a black canvas, in Queens, contact Departure 126.8 in New York.

Climbing 500 feet, the autopilot engaged, to control Side Navigation and rate of climb, retract the flaps to double slit behind on the position of five degrees.

Ascending 3400 feet, yet it instructed to conduct a 060-degree position and climb and maintain 11,000 feet. Crossing Long Island on a diagonal path, which took more than 6,000 feet per minute climb at a speed of 220 knots, cabin, never in the wake of increasingly locked. The promotion list has been completed.

New instructions to download and maintain 17,000 feet, Flight 614 fell through a cloud of smoke to cover Connecticut, overcoming Misty 24,000 foot summit where the last trace of blue ice was temporarily lit by lightning.

Apparently trapped in a black, steam from the turbulence vacuum incubation, the slender, narrow body, driven by its large diameter, providing the engine of life, settled in their tray assigned flight level 350, evicted from his left wing by a blue line from the Arctic to Portland, Maine. The VNAV has been hired.

Dinner, detailed the saga of "Business Class Menu" and preceded by a selection of aperitifs and spirits, including "Pate Diplomatic and jumbo shrimp on a bed of lettuce with lemon and cocktail sauce, seafood with Pernod sauce with saffron or veal tenderloin roasted in Cream Sauce mushrooms served with tortellini, green beans and carrots, a selection of reds and whites, a basket of bread and butter of Iceland; Bel Paese cheese Italian soft cheese, slices of Gouda cheese, crackers, red grapes, and nuts, cheese cake with raspberry sauce topped with shavings of chocolate, coffee, a selection of spirits, hazelnut and French full of chocolates.

Caught in the black void, without reference continued its north-question Atlantic to the east, the Boeing 757 had made his way unseen Intercontinental in Saint John, New Brunswick, the Gulf of St. Lawrence, and Goose Bay, Labrador, before leaving for the North American continent on the oceanic feeling, the only light visible outside the cockpit feel today intermittent, in the correction of the fuselage on the port engine cover.

With the location of the northern hemisphere of the sun, However, the day is quickly appeared, time in Iceland in 0340 or 2340, New York time, as a thin, dull blue light, cold, separating the sky last night the black surface, indistinguishable from the ocean and smoke, the slab and lower layers of clouds. This line represents horizon. Somewhere beyond the left was the tip of Greenland and the north of it, Narssarssuaq. The blue line intensified.

Pale green glow of Dawn back, piercing the layers of clouds with fire intensity, the sky turned into a series of dark red and copper lines, the system Light snow cumulostratus Arctic cloud cover seems that now became visible below the wing media around the engine.

From automatic landing, aircraft installed TI-FIH to reduced power of 3,500 feet per minute descent, passage through 32.000 feet and speedometer has surpassed the 300-mark node. engine parameters, varying the engine includes an engine pressure ratio of 096, a speed of 390 fans, and temperature exhaust gas 307. landing weight after combustion of fuel along the way, has been calculated for 180,000 pounds well below its maximum.

Supported penetration of turbulence and white and gray clouds that produce tendrils at 16,000 feet, the Twin pierced in the dark ball with his nose, now assuming a rate of descent of 1,800 feet per minute. To adhere to the speed limit of 10,000 feet, speed is fixed at 250 knots and the altimeter at 2,000 feet.

The descent to 9000 meters from the surface, 500 feet per minute price, the commander cut the ILS approach chart for runway 20 Keflavik International Airport to the yoke control, set the automatic information service (ATIS) and noting the cloud cover, rain and a temperature more than nine degrees Celsius for our arrival.

Penetrating the density of gray in a 089-degree position, the aircraft descended through 2,900 feet when the light in which altitude warning on, indicating the arrival imminent series above-2 ,000-foot limitation. Indicated air speed (IAS), will now be done to 215 "," node mark.

Speed of flight expansion edge flap, as the cab displays, 240 knots indicated a degree, 220 for five degrees, 210 to 15, 195 20, 190 25, and 162 to 30.

Spread the darkness, at 2,000 feet, the 757 came in navy blue, gray, silver Atlantic stopping for a moment of his descent and mobilization on the right bank to a line of 141 degrees and the tip of Iceland. The indicated airspeed was composed the establishment number 180-node.

Extending fins dual slot position five degrees, served as air velocity trademark of nodes 200, Flight 614 maintains the focus end, a 201-degree departure.

Lever landing gear, down to 180 knots for reviewing the final list approach had been followed by the marginal eyelash extensions at 20 - and finally, 30 posts at the second, which coincides with knowledge, nose down attitude at a speed of 158 knots. Plagued by rain, the plane was approaching the red light and white threshold track, beyond which the contact line in the target could be seen through the pods of low clouds.

Passing through the moss green and brown gold, paved with lava fields and the colorful rooftops of Keflavik, fell into the 757-200 level of 1000 feet up a 500-per-minute rate, speed 143 nodes connected to VREF, and narrowed the gap to the track 20 in the midst of a gradual and automatic flashes altitude asked: "100 ... 50 ... 40 ... 30 ... 20 ... 10.

Deaf to the concrete with its quad-wheeled main units coated landing gear, the Twin rebowed to Earth until his front tire in contact with equal white light, centered on the tape, its reverse thrust and manages speedbrake and armed.

Low speed calls, imitating the show during the epidemic, there were "80 ... 70 ... 60 ... 50 ", when which the inverter mode and push off the concrete was moving just under the windows of the cab.

Turning off the runway, now with the help of Cane nose wheel, the body long and narrow double, have somehow mistakenly assumed the identity of an intercontinental aircraft, the door slid beside Icelandair IT-registered 737-400 FIB-like wand instructions Marshaller has increased in size until only a few inches nose, where the parking brake was engaged jetbridge accordion and spread to the second gate of the port.

Demand increased on the roads due to the 757, and the elasticity inherent in the design, led to the first type, version and only in different sizes, which provided the headquarters of ten per cent below-mile costs and increased its passenger capacity and cargo volume soil, respectively, 20 and 50 per cent.

First announced September 2, 1996, after Flugdienst German charter airline Condor has placed an order for 12 companies and an option on 12 aircraft, type, named "757-300", proposed a fuselage section of 23.4 meters, consisting of a ceiling 13.4 meters in front of the wing and a sheet of ten meters behind it, producing a new and 178.7 meters in total length. The most important the Twin single-engine boats, long overshadowed by the four-engine DC-8 Super 60 series, which could accommodate 289 single-class six passengers per day in a field of 29 inches, although a more typical mix of available standard class involves 12 first-class, four posts a day in a field of 36 inches and 231 classroom Economic six posts a day in a field of 32 inches, all on the long 141.9 meters long, wide bridge model for the Next Generation 737. Weak cover volume also increased to 1071 cubic feet in the forward cargo compartment and 1299 cubic feet in the aft compartment.

To resolve the tensions created by increasing the longer fuselage has been strengthened wings, a high lift device, the motor turns and landing gear and guaranteed protection for the tail skid rotation angles too.

Also powered by two Rolls Royce turbo RB.211-535E4 double flows, the aircraft had a maximum of 240,000 pounds takeoff weight and a range of 2.055 nautical miles with 243 passengers.

The prototype 757-300, NU701 and the 804th meeting series aircraft has been deployed in Renton, Washington, May 19, 1998, and began flying in the first three months later, August 2, completing a successful 2.5-hour flight which peaked at 250 knots indicated airspeed and 16,000 meters. used in maintaining airworthiness and the initial field of controllability core program of flight tests, explored flutter, stalls, stability and control, and demonstrated the need for the installation of vortex generators in the vanguard of the external door to improve the characteristics Position.

Two other cells, NU721 and NU722, has enabled the achievement program collectively 356 flights totaling 912 hours, and leads to certification FAA ETOPS for the 180 minute raid January 27, 1999 Operating shorter cycle from design to production of any previous Boeing, which spanned 27 months.

Condor inaugurated type Revenue Service two months later, on March 19.

Improvements to existing 757-200-300 has been concluded with Aviation Partners Boeing Blended Winglet Program modernization. fins with large radii and the chord changes smoothly in the transition points, avoiding concentrations producing vortex drag and provide optimal downforce, resulting in wingtips eddies smaller than any right wing or winglet systems with conventional angular transitions occur.

The reshuffle, which carried a weight of 1320 pounds, is an outer skin and replacing the coast, to tighten the bar tanks, the lowest responsible for the replacement of closure, leading edge flaps additions vortex generator and the position of the New and the fight against the installation of Anti-collision light.

The system, an increasing scope of 124.10 at a current ex 134.9 feet, she has presented numerous economic benefits and performance, as an average annual savings to fuel planes 300,000 U.S. gallons.

The first eight feet, two inches winglet equipped 757, a -200 series aircraft owned by Continental Airlines, performs its first flight March 9, 2005 in Everett, Washington, and now the program is considered a resounding success.

V

The October 18, 2004, the 1050 th and final Boeing 757, long original series -200, left the final assembly plant in Renton and was delivered company to Shanghai, China next year.

The device was designed as an increased capacity, twin-engine advanced for the 727, and as a capacity smaller narrow-body complement that developed simultaneously 767, for a one-stop transcontinental routes, are filled two markets, thus creating one of their final becoming both more capacity and long-range intercontinental variations. 1049 Aircraft delivered, 913 were 757-200s, 80 were 757-200pF, there was a 757-200M and 55 were 757-300.

The victim of the recession and reduction in post-9/11 air travel, the type has been largely usurped by the next generation of Boeing 737 and Airbus A-321 itself, because the small seating capacity of more suitable to the changing demands of the road. 787-8 While this may provide replacement capacity in limited areas high capacity of 757, not directly, the consideration of the design progress is expected, with high-end versions of the Boeing 737 itself may be considered as a possible replacement for his successor. However, the guy who represents the ultimate single-aisle aircraft, two aircraft engine development, payload and range parameters much higher than those traditionally associated with the configuration of this type.
