The best of these new tech­nolo­gies is that they have in­ter­op­er­abil­ity of sys­tems, elec­tronic flight bag, con­nec­tiv­ity and data an­a­lyt­ics that will help air­lines in air traf­fic management, fuel management and dayto-day op­er­a­tions

THE AVI­A­TION IN­DUS­TRY IS poised for a pe­riod of un­prece­dented tech­no­log­i­cal change, pro­vid­ing sig­nif­i­cant op­por­tu­ni­ties and chal­lenges for air­lines and sup­pli­ers alike. Air­lin­ers are al­ready go­ing seis­mic tech­no­log­i­cal changes as to help air­lines im­prove per­for­mance, fuel ef­fi­ciency and pas­sen­ger com­fort. There is go­ing to be an ac­cel­er­a­tor ef­fect of these tech­nolo­gies on the bot­tom line of air­lines and new tech­nol­ogy air­craft will inevitably chal­lenge the com­pet­i­tive land­scape of the in­dus­try. These new tech­nolo­gies are cen­tred around oper­a­tional ef­fi­ciency which will fa­cil­i­tate im­proved schedule re­li­a­bil­ity and pas­sen­ger ser­vices. The best of these new tech­nolo­gies is that they have in­ter­op­er­abil­ity of sys­tems, elec­tronic flight bag, con­nec­tiv­ity and data an­a­lyt­ics that will help air­lines in air traf­fic management, fuel management and day-to-day op­er­a­tions. We look at some of the new tech­nolo­gies in up­com­ing air­craft from dif­fer­ent air­framers and how they are go­ing to make a dif­fer­ence to the bot­tom­line of an op­er­a­tor.

BOE­ING 737 MAX FAM­ILY LEADS SIN­GLE-AISLE MARKET WITH TECH­NOL­OGY

The Boe­ing 737 MAX fam­ily of air­craft is al­ready chang­ing the face of the sin­gle-aisle market. Ev­ery air­plane will fea­ture the new Boe­ing Sky In­te­rior, high­lighted by mod­ern sculpted side­walls and win­dow re­veals, LED light­ing that en­hances the sense of spa­cious­ness and larger piv­ot­ing over­head stowage bins. The 737 MAX fam­ily is de­signed to of­fer the great­est flex­i­bil­ity, re­li­a­bil­ity and ef­fi­ciency in the sin­gle-aisle market.

The 737 MAX in­cor­po­rates the lat­est tech­nol­ogy CFM In­ter­na­tional LEAP-1B en­gines, ad­vanced tech­nol­ogy winglets and

other im­prove­ments to de­liver the high­est ef­fi­ciency, re­li­a­bil­ity and pas­sen­ger com­fort in the sin­gle-aisle market.

The 737 MAX 8 re­duces fuel use and CO2 emis­sions by an ad­di­tional 14 per cent over to­day's most fuel-ef­fi­cient sin­gle-aisle air­planes. The 737 MAX 9 is the sec­ond mem­ber of Boe­ing’s in­dus­try lead­ing 737 MAX fam­ily, with a max­i­mum ca­pac­ity of 220 pas­sen­gers and a range of 3,515 nau­ti­cal miles. The 737 MAX 9 is sched­uled to en­ter service in 2018. The 737 MAX 8 is on track to de­liver to cus­tomers in the sec­ond quar­ter of 2017.

AIR­BUS A320­NEO FAM­ILY INNOVATION AT ITS BEST

The market-lead­ing A320­neo ( new en­gine op­tion) Fam­ily is the world’s best-sell­ing sin­gle-aisle air­craft prod­uct line – pro­vid­ing un­beat­able ef­fi­ciency and com­fort to its global cus­tomer base. As a ref­er­ence for tra­di­tional air­lines and low-cost car­ri­ers alike, NEO air­craft ben­e­fit from Air­bus’ rep­u­ta­tion for con­tin­u­ous innovation. Among the en­hance­ments in­cor­po­rated on A320­neo Fam­ily jet­lin­ers – which com­prise the A319­neo, A320­neo and A321­neo – are two lat­est-gen­er­a­tion pow­er­plant choices (Pratt & Whit­ney’s PurePower PW1100G-JM and the CFM In­ter­na­tional LEAP-1A), the in­cor­po­ra­tion of sharklets wingtip de­vices and ad­di­tional cabin op­ti­mi­sa­tion. These im­prove­ments will re­sult in 20 per cent fuel sav­ings per seat com­pared with cur­rent en­gine op­tion (CEO) air­craft by 2020, along with two tonnes more pay­load, up to 500 nau­ti­cal miles ad­di­tional range, lower op­er­at­ing costs, and reductions in en­gine noise and emis­sions.

In Jan­uary 2016, this new era in sin­gle-aisle ef­fi­ciency of­fi­cially opened with the de­liv­ery of the first A320­neo fam­ily air­craft – and A320­neo equipped with Pratt & Whit­ney PurePower Geared Tur­bo­fan en­gines – to launch op­er­a­tor Lufthansa. As of March 2017, the A320­neo Fam­ily had re­ceived more than 5,000 or­ders from over 90 cus­tomers.

The A320­neos boast the very lat­est en­gines, large wingtip de­vices (sharklets) and an in­no­va­tive cabin and con­tinue to go from strength-to-strength as the most com­fort­able, fuel-ef­fi­cient and en­vi­ron­ment-friendly sin­gle-aisle air­craft.

Air­bus re­mains at the cut­ting edge of the avi­a­tion in­dus­try; lead­ing the way in terms of innovation and progress. The de­sire to con­tin­u­ously im­prove tech­nol­ogy is em­bed­ded within the heart of the com­pany, which allows Air­bus to con­stantly de­liver proven new tech­no­log­i­cal ad­vance­ments that push the boundaries of what is pos­si­ble. This means that all stake­hold­ers can ben­e­fit from proven high qual­ity im­prove­ments in de­sign, man­u­fac­tur­ing, op­er­a­tions and main­te­nance. Such ad­vances in­clude the in­tro­duc­tion of full fly-by-wire flight con­trols tech­nol­ogy, em­ploy­ing mod­ern ma­te­ri­als in its air­frames, and de­vel­op­ing cock­pit de­signs that im­prove pi­lot work­load and ef­fi­ciency.

A350 XWB GO­ING THAT EX­TRA MILE

The A350 XWB flight deck fea­tures max­i­mum com­mon­al­ity with Air­bus’ com­pre­hen­sive market-lead­ing prod­uct line. In the A350 XWB’s ‘front of­fice’, its flight deck has been up­dated – built around an ar­range­ment of six iden­ti­cal, in­ter­change­able large dis­plays. This is a con­tin­u­a­tion of Air­bus’ phi­los­o­phy for cre­at­ing er­gonomic flight decks that com­bine com­mon­al­ity and innovation.

Pro­vid­ing max­i­mum com­mon­al­ity with Air­bus’ other jet­liner fam­i­lies, this flight deck con­fig­u­ra­tion is fully aligned with the com­pany’s unique Cross Crew Qual­i­fi­ca­tion con­cept – which gives pi­lots the pos­si­bil­ity of tran­si­tion­ing from one Air­bus air­craft type us­ing dig­i­tal fly-by-wire con­trols to an­other via dif­fer­ence train­ing in­stead of full type rat­ing train­ing. In ad­di­tion, the con­cept allows for full in­ter­change­abil­ity of the A350 XWB flight deck’s large dis­plays in cases of fail­ure.

With its state-of-the-art Rolls-Royce Trent XWB en­gines, the A350 XWB is able to out­per­form com­peti­tors in terms of fuel econ­omy, emis­sions and over­all ef­fi­ciency. These light­weight, three-shaft pow­er­plants – the lat­est in Rolls-Royce's Trent fam­ily – is pro­duced us­ing ad­vanced man­u­fac­tur­ing tech­niques for a lighter, more ca­pa­ble and highly ef­fi­cient en­gine. It fea­tures high-tech ma­te­ri­als, coat­ings, en­gine ar­chi­tec­ture, and cool­ing tech­nolo­gies – in­clud­ing a third-gen­er­a­tion low-speed fan and con­tra-ro­ta­tion op­er­a­tion.

With a sin­gle en­gine type for the com­plete A350 XWB jet­liner fam­ily, the Trent XWB pro­vides com­mon­al­ity across the prod­uct line – at thrust ratings of up to 97,000 lb. Ad­di­tional ben­e­fits in­clude mo­d­ule weight sav­ings of 15 per cent, along with aero­dy­namic ef­fi­ciency im­prove­ments through the use of com­pres­sor blisk (bladed disk) tech­nol­ogy.

REV­O­LU­TION­ARY DIG­I­TAL MOCK-UP

The A350 XWB's rev­o­lu­tion­ary dig­i­tal mock-up is a ‘gamechanger’. Air­bus has cre­ated a bridge be­tween the vir­tual and real worlds with its A350 XWB dig­i­tal mock-up, which pro­vides a high-def­i­ni­tion rep­re­sen­ta­tion of the air­craft — right down to the smallest parts — on com­puter screens. It also re­in­forces Air­bus’ role as an in­te­gra­tor, and cap­i­talises on the com­pany’s decades of ex­pe­ri­ence from pre­vi­ous pro­grammes. This very re­al­is­tic dig­i­tal ver­sion of the A350 XWB has lit­er­ally changed the way air­craft are con­ceived, as it allows an ac­cu­rate vi­su­al­i­sa­tion of where sys­tems are lo­cated dur­ing de­sign, how they are in­stalled in pro­duc­tion and what ac­cess is avail­able for main­te­nance dur­ing the jet­liner’s oper­a­tional lifetime.

EM­BRAER E-JETS E2 TRULY IN­NO­VA­TIVE

The Em­braer E-Jet E2 fam­ily is a fam­ily of three nar­row-body medium- range twin-en­gine jet air­lin­ers de­vel­oped by Bra-

THE NEW TECH­NOLO­GIES ARE CEN­TRED AROUND OPER­A­TIONAL EF­FI­CIENCY WHICH WILL FA­CIL­I­TATE IM­PROVED SCHEDULE RE­LI­A­BIL­ITY AND PAS­SEN­GER SER­VICES

zil­ian aero­space com­pany Em­braer, re­plac­ing the pre­de­ces­sor Em­braer E-Jet fam­ily. The three vari­ants share the same fuse­lage cross sec­tions with dif­fer­ent lengths and three dif­fer­ent new wings, Pratt & Whit­ney PW1000G geared tur­bo­fans in two sizes, fly-by-wire con­trols with new avion­ics, and an up­dated cabin with 40 per cent en­larged bag­gage bins. An­nounced im­prove­ments per seat are 16 to 24 per cent lower fuel burn and 15–25 per cent lower main­te­nance costs. The E2 fea­tures a closed loop fly-by-wire con­trol, which – ac­cord­ing to Em­braer – re­duces weight, in­creases fuel ef­fi­ciency, en­hances con­trol and in­creases safety by full en­ve­lope pro­tec­tion in all flight phases.

An­a­lysts ac­count the fuel sav­ings of the now closed loop fly-by-wire con­trol at 1.5 per cent be­cause of de­sign changes pos­si­ble due to the en­hanced flight sta­bil­ity and the re­sult­ing in­creased lift (lower tail down­ward force) and weight sav­ings and drag reductions re­lated to the 26 per cent re­duc­tion in the hor­i­zon­tal tail size.

The E2 fam­ily has a new wing and land- ing gear In the E190-E2, of the 16 per cent better fuel burn, 11 per cent comes from the geared tur­bo­fan, 3.5 per cent from the im­proved aero­dy­nam­ics of the new high as­pect ra­tio wing and 1.5 per cent from the fly-by-wire, en­abling a 250 ft hor­i­zon­tal sta­biliser from 280 ft on the E190/ E195.

The E2 fam­ily has AHEAD-PRO, which is a com­pu­ta­tional web-based plat­form to con­tin­u­ously mon­i­tor the health of the fleet, pro­vid­ing timely main­te­nance in­for­ma­tion in a friendly and straight­for­ward way. With AHEAD-PRO air­craft sys­tems health con­di­tion is sys­tem­at­i­cally as­sessed and un­planned main­te­nance of mon­i­tored sys­tems is avoided by means of fail­ures oc­cur­rence pre­dic­tion. More­over the ac­tiv­i­ties of fault iden­ti­fi­ca­tion, trou­bleshoot­ing and re­sources plan­ning oc­cur be­fore the air­craft lands its des­ti­na­tion, op­ti­miz­ing air­line turn­around-time be­tween flights. AHEAD-PRO of­fers func­tion­al­i­ties to op­ti­mize all steps to ex­e­cute Health Mon­i­tor­ing process in the air­line, from data ac­qui­si­tion to time-to-fail­ure prog­no­sis.

E2’s ad­vanced in­te­grated avion­ics sys­tem pro­vides ex­cep­tional sit­u­a­tional aware­ness en­hanced by large land­scape dis­plays and re­duced pi­lot work­load. In­no­va­tive tech­nolo­gies such as syn­thetic vi­sion and ad­vanced flight management sup­port more fuel-ef­fi­cient di­rect ap­proaches to air­ports. Cock­pit com­mon­al­ity with cur­rent-gen­er­a­tion E-Jets allows for a smooth tran­si­tion to the new E2 plat­form. The new fea­tures are wire­less con­nec­tiv­ity; en­hanced central main­te­nance com­puter; SmartView; im­proved nav­i­ga­tion; next gen­er­a­tion FMS; im­proved sit­u­a­tional aware­ness (cock­pit dis­play of traf­fic); In­tuVue 3D weather radar; SmartRun­way and SmartLand­ing.

The wing and en­gine com­bi­na­tion for the E175-E2 and a com­mon larger wing and en­gine for the E190-E2/E195-E2 are op­ti­mised to de­liver max­i­mum per­for­mance. Pratt & Whit­ney PurePower Geared Tur­bo­fan En­gine E2’s new GTF en­gines — the PW1700G (E175-E2) and PW1900G (E190-E2 and E195-E2) — have an ad­vanced gear sys­tem that allows the en­gine’s fan to op­er­ate at a dif­fer­ent speed than the low-pres­sure com­pres­sor and tur­bine. They work in com­bi­na­tion with new aero­dy­nam­i­cally ad­vanced wings and other ad­vanced con­trols and sys­tems to cre­ate dou­ble digit im­prove­ments in fuel burn, main­te­nance costs, emis­sions, and ex­ter­nal noise.

THE WORLD’S LEANEST AIR­CRAFT FROM BOM­BARDIER

The Bom­bardier CSeries is a pur­pose-de­signed and built from the ground up. The CSeries air­craft’s cut­ting-edge de­sign, cou­pled with the Pratt & Whit­ney PurePower PW1500G en­gine, cre­ates an air­craft that is the per­fect bal­ance of proven meth­ods, ma­te­ri­als and lead­ing edge tech­nol­ogy.

The air­craft are ul­tra-mod­ern, from en­gines to en­gi­neer­ing, en­sur­ing that op­er­a­tors en­joy value to­day and growth to­mor­row. The air­craft is equipped with an ad­vanced flight deck, flyby-wire con­trols, ad­vanced ma­te­ri­als, and air­craft health management sys­tem (AHMS). The C Series AHMS has the power to change how air­line main­te­nance crews man­age their ac­tiv­i­ties, re­sult­ing in fewer me­chan­i­cal de­lays and su­pe­rior dis­patch re­li­a­bil­ity. The cut­ting-edge flight deck in­cludes large LCD dis­plays as well as dual flight management sys­tems with op­ti­mized con­trol and dis­play func­tions, dual cur­sor con­trol de­vices, datalink, Cat IIIa au­toland and side­stick con­trols as base­line. The re­sult is an in­te­grated avion­ics ex­pe­ri­ence that in­creases pi­lot sit­u­a­tional aware­ness and re­duces work­load.
