737_A320NEO_E175Perf

Three jetliner manufacturers, Airbus, Boeing and Embraer, in alphabetical order, rolled out single aisle firsts in March this year.

It started on March 12th, when Embraer rolled out the first production E175 with fuel burn improvements. New winglets, and fuselage wide aerodynamic “cleanups”, and system optimizations have bettered fuel consumption by 6.4%: a good 1.4% better than the technical team had expected to see in fuel savings, on a “typical flight”, which, according to The Flying Engineer estimates, are in the 500-1000NM region. This 6.4% fuel burn reduction is close to double the figure Airbus achieved with its A320 when it strapped on the winglets it calls Sharklets: between 3-4%, and more than 3 times what Boeing achieved with its 737NG when it rolled out the 737 Performance Improvement Package (PIP) in 2012: 2%.

On March 17th, Airbus announced the final assembly of its A320NEO: the next landmark in mainline single aisle airplanes. The A320NEO will be the first single aisle airplane in its class to enter service, with a new type of engine in this thrust class: the Geared Turbofan Engine. The GTF is expected to set the A320NEO apart from the 737MAX; the latter is expected to fly with the CFM LEAP-1B engine that runs hotter, leaving little room for any engine growth in the future.

On March 20, Boeing rolled out the first Boeing 737NG at increased production rate: 42 airplanes a month, matching what Airbus had achieved almost a year ago: which then was the highest commercial aircraft monthly production rate ever. The interesting feat here is that Boeing achieves this at a single facility, while Airbus gets its 42 airplanes a month at its three final assembly lines: Toulouse, Hamburg, and Tianjin.

As for Bombardier, which is going through a very difficult period, the First CS300: the only aircraft variant in the CSeries program that is relevant today and has garnered much attention from customers, almost twice the firm orders as the shorter variant, the CS100, is in final assembly and the systems are being installed. First flight of the CS300 is expected soon, and the entry into service of the CS300 is expected 6 months after the CS100, the latter slated for the second half of 2015, with the hope that no further program delays are announced.

Airbus A320NEO Enters FAL (MSN6101)

A320 MSN 6101 FAL

Airbus’ first A320NEO, MSN 6101 (A320-271N) has entered the final assembly line (FAL) at Toulouse, marking yet another milestone in the A320NEO program. The forward fuselage, which arrived from St. Nazaire in France, and the aft fuselage, which arrived from Hamburg in Germany, were mated at the FAL, marking the start of the final assembly.

The next stage is the joining of the wing to the fuselage. Overall, it takes about one month to complete the final assembly of an A320 Family aircraft.

The A320 program crossed a major milestone in November 2013, when the assembly of the first major component- the engine pylon- took place.

First flight is expected in the Autumn of 2014, almost 4 years after the program was launched in December 2010. Airbus took the landmark decision of re-engining the A320 Family after sensing imminent competition from Bombardier’s C-Series airplanes.

Airbus will retain 95% airframe commonality with the present A320, offering the benefit of high dispatch reliability associated with a mature airframe. Airbus has also effected incremental changes to its traditional Airbus A320, thereby eliminating the risks associated with too many modifications in one shot.

In the November of 2011, Airbus flew the first A320 with the version of the sharklets that are now seen on all new production Airbus A320 airplanes, first sharklet-equipped A320 being MSN 5428 delivered in December 2012. The sharklets, which will feature on the A320NEO as well, introduce fuel savings of upto 4% on long flights. Preliminary wing strengthening to handle the aerodynamic loads introduced by the sharklets, and airplane-wide weight reduction to offset the weight due to the strengthening have already been effected.

NEO’s difference from today’s in-production A320 aircraft is the further strengthening of the wing and fuselage to handle the loads associated with the heavier and larger New Engine Option (NEO): The Pratt and Whitney PW1100G and the CFM LEAP-1A. The new more efficient engine together with the sharklets realize a 15% fuel savings on 800nm route lengths, and up to 16%+ on the longer routes, compared to non-sharklet fitted Airbus A320 aircraft.

The Pratt and Whitney Geared Turbofan Engine PW1100G series for the A320, took to the skies in May 2013, on a Pratt and Whitney Boeing 747SP flying test bed.

Changes to the A320 are minimal and the least among other airplanes which are being re-engined and  modified to a larger extent, such as the Boeing 737MAX and the Embraer Second Generation E-Jets E2. Historically, all new airplane programs have been met with significant dispatch reliability issues related to technical or maintenance issues associated with an immature airframe. The A320NEO program has the least changes, followed by the MAX and E2 program. The all-new Bombardier C-Series introduces many firsts for Bombardier, making it the program that may likely have the most number of issues, initially atleast: a reason which explains the low number of firm orders: 201, despite having 3 flying airplanes in the test campaign.

 In contrast, the Embraer E-Jet E2 program, which airplanes are still “paper” (conceptual), has 200 firm orders. The Boeing 737MAX has 1,807 firm orders and the Airbus A320NEO program has firm orders for 2,667 airplanes.

Least changes with benefits where it matters to an already proven and mature airframe, incremental modifications, early introduction into service (Q4 2015), a dual engine source (all other new/re-engine programs have only one engine supplier), keeping up program development schedule, and the smallest training impact have contributed in large to the sales success of the program.

IndiGo has an order for 180 Airbus A320NEO Family aircraft, which include the A320NEO and A321 NEO. Go Air has 72 airplanes on order, and Air Asia 264 A320NEOs on order. Both IndiGo and GoAir’s A320NEOs will be powered by the Pratt & Whitney PW1100G. IndiGo operates the IAE engines, of which Pratt and Whitney is a part. Go Air which flies CFM powered A320 aircraft, has switched engine suppliers, to Pratt and Whitney. The PW1100G engines offer two advantages: Room for growth, and availability sooner than the CFM LEAP-1A Engines. Air Asia, which flies CFM powered A320s, has opted for the CFM LEAP-1A to power its NEOs.

Switching Fleets: More Boeing to Airbus than the other way around

This piece covers Boeing’s slipping grip on the low-cost airline market, with a focus on Asia: how, why, and where.

Air Asia, and EasyJet, operators of Airbus A320 airplanes, were once Boeing 737 operators. Airbus has been on a “rampage”, trying to trespass Boeing’s narrowbody territory, and plant what is today the world’s best selling airplane family.

Air Asia, which until as recently as 2010 operated Boeing 737-300 aircraft, is now an all Airbus A320 operator: operating 73 of them. Air Asia Indonesia, which also operated Boeing 737-300s, now flies 30 Airbus A320 airplanes. Lion Air of Indonesia, which operates 99 Boeing 737 aircraft, most of which are 737NG airplanes, placed a firm order for 234 Airbus A320 aircraft, including 60 Airbus A320 classic engine option airplanes. Garuda Citilink, established in 2001 as a low-cost subsidiary of Garuda Indonesia, which operated an all Boeing 737-300 and 400 fleet, now flies 24, more efficient Airbus A320s with the callsign “Supergreen”.

Jet Airways has evaluated Airbus A320NEOs, and Neil Mills, the then CEO of SpiceJet, publicly announced the evaluation of a fleet switch to the A320NEO.

Boeing’s comeback: an order of 54 Boeing 737s, comprising 23 737-800s and 31 737 Max 8s from SilkAir, the regional wing of Singapore Airlines, which welcomed its first Boeing 737-800 (9V-MGA) at the Singapore Airshow 2014, marking the start of SilkAir’s transition to an all-Boeing fleet, from the existing fleet of 24 Airbus aircraft, comprising 6 A319s and 18 A320s. (see photo on top)

After SilkAir, Boeing is now trying to sway TigerAir to adopt its airplanes.

How: Airbus’s Successes.

Said Dinesh Keshkar, vice president, Asia-Pacific & India Sales for Boeing Commercial Airplanes, in February 2013, after Spicejet and Jet Airways performed financially better, (after the demise of Kingfisher), “Can they sustain these yields, which I think they can because of the balance of capacity in the market. They will continue to do well and aviation will continue to grow profitably. The Indian commercial aviation market is improving with higher yields and stability in fuel charges”.

The same Keshkar in February 2014 admitted that Indian carriers are “not doing well” due to the decline in the rupee, high fuel costs, and high capital costs and taxes in India. “Certainly the Indian market is not for the faint-hearted. It’s hard to make money there. Nevertheless, everybody realizes that it’s a great market and that’s why more and more people are trying to get into that market.”

Said Kiran Rao, executive vice president for strategy at Airbus, in January 2013, “It’s quite understandable that with the high fuel prices and the Indian taxes, the neo really works in India,” he says. “Jet Airways and Spicejet are predominately Boeing airlines today, but we will give it a good shot.”

Two things make the Airbus A320NEO attractive: Great operating economics, and its availability atleast 2 years before the Boeing 737MAX. That gives operators the chance to start reaping the benefits of an economical airplane two years before its competition, and that amounts to saving big money.

To put things in perspective, final assembly for the first Airbus A320NEO will start in March 2014, for the planned maiden flight in autumn, kicking off a flight-test campaign with 8 Airbus A320NEO airplanes, all flying with PW1100G Geared Turbofan Engines. In contrast, the engine that will power the 737MAX, the GE-SNECMA CFM LEAP-1B variant may not take to the skies this year, as the engine manufacturer plans to begin flight tests of the A320NEO’s alternate engine, LEAP-1A, on GE’s Boeing 747 flying testbed in September 2014.

The A320NEO is expected to enter service in late 2015, while the Boeing 737MAX is expected to enter service in late 2017.

“In a high fuel cost environment, it only makes sense to consider all of the available options. We must look at the aircraft that will have the lowest operating costs and see how it fits into our fleet,” said Neil Mills in March 2013, talking about the possible switch to the Airbus A30NEO, to meet medium term fleet requirements.”We will switch from one aircraft type to another if needed. I was with Easyjet when we switched from Boeing to Airbus and we can do the same here.”

The Boeing 737-800, which compares & competes directly with the Airbus A320, burns more fuel for the same payload. The Boeing 737-800 with winglets burns as much fuel as the A320 for the same range, payload, and cruise altitude. The A320 with “sharklets”, however, beats the Boeing 737-800W, and the A320NEO, goes unmatched.

But getting efficient airplanes two years earlier isn’t everything.

A continuing fight in the World Trade Organization is between the U.S. and the European Union over government support to Boeing and Airbus. The U.S. charges that European government subsidies have allowed Airbus to undercut Boeing prices, giving Airbus an unfair advantage in the marketplace and harming the U.S. aerospace industry: Boeing has significantly streamlined its 737 production during the past two years, but company officials said their cost improvements still don’t enable them to break even at the prices Airbus is quoting for the A320.

Although Keskar says that he is “not even going to try” reaching out to AirAsia because of the large number of A320s the carrier has on its order books, Boeing apparently hasn’t stopped trying to sway the airline in its favour. However, Boeing isn’t willing to sell at any price, even though Airbus is charging far less than Boeing is willing to accept. Boeing marketing Vice President Randy Baseler said “the only standard Airbus is setting is with price” on the 2004 Air Berlin deal, in which the German carrier ordered 70 Airbus A320 aircraft . “If you cut your prices enough, anybody will take them,” he said.

Few analysts feel Airbus offers a discount of as much as 60% to sway orders in their favour, while Airbus plays down the discount.

The matter only worsens with the projected 737MAX development costs expected at twice that for the A320NEO. The 737MAX is undergoing far more changes than the famous Airbus narrowbody family.

The territories.

Boeing has lost out the no-frills, low cost airline segment to Airbus. Boeing once had monopolized this segment, especially with Southwest operating 588 Boeing 737 airplanes, and RyanAir operating 298 airplanes. Now, almost all start up low cost airlines fly the Airbus A320.

India’s “model” airline, IndiGo, and other start-ups: Air Deccan, Go Air, and Kingfisher Airlines (which eventually added the low cost arm Kingfisher RED) either fly or flew Airbus A320s. New airlines on the Indian horizon, whether credible or not, plan an A320 fleet: Skyjet Airways, and Volk Air.

TATA-SIA, the most talked about airline, will have an A320 fleet of 20, all leased, and AirAsia India, in line with the other AirAsias, will also fly with Airbus A320 aircraft.

SilkAir, with a brand that is not low cost but rather full service, will feature a cabin layout of 12 Business Class and 150 Economy class seats, representing an eight percent increase on SilkAir’s current seating capacity on the dual class A320s.

The only advantage in switching to a 737NG, for SilkAir, is increasing capacity without compromising on comfort through seat pitch. But it takes a lot to convince an airline to switch; especially when they could have flown more economical with the A320 sharklets, and saved on fleet transition costs. The real reason lies behind closed, motionless lips.

Stating a SilkAir press release, “A full-service carrier that is committed to creating enjoyable and reliable travel experiences, enhancements that customers can look forward to on the new aircraft include features such as the Boeing Sky Interior, which highlights new modern sculpted sidewalls and window reveals, LED lighting that enhances the sense of spaciousness, larger pivoting overhead stowage bins as well as in-seat audio and power supply for added convenience.”

Then why was Spicejet, a low cost, missed by Airbus? SpiceJet began services in May 2005, when Air Asia was still flying an all Boeing 737 fleet, and just one year after EasyJet began transitioning to a predominantly Airbus A319 fleet. It was only in the December of 2005 that AirAsia received its first Airbus A320.

Said Kiran Rao, “We should have won the SpiceJet order the first time around, but it is just that at the time we had so many orders and took our eye off the ball,”.

But TATA-SIA, a full service carrier, should have been the target of Boeing. Dinesh Keshkar said that with the huge backlog for the 737, it was not able to provide narrowbodies to Tata SIA in line with its target to start operations in 2014.

The Indian MAX announcement that never came

Boeing in late 2012 had hoped to take its first order for the 737 MAX from an Indian airline. This hope was rekindled when Boeing had mentioned revealing a “sizable order” for the MAX from an Indian carrier, during the 2014 Singapore Airshow.

Twice, Boeing’s announcements never came, although media reports Jet and SpiceJet have signed for Boeing 737MAX airplanes, in the double digit range.

This is in sharp contrast to Airbus A320NEO orders placed by IndiGo and GoAir. Further widening the Airbus-Boeing gap are reports of the likelihood of IndiGo placing an order for 200-250 “more” aircraft.

Recording the largest aviation growth, Asia is where all airplane manufacturers have trained their guns. But Asia is a cost conscious market, where the likes of low cost airlines sprout often and thrive. That makes, statistically, a great market for Airbus, and a bleak outlook for Boeing, for now atleast. Few orders for Boeing 737 airplanes are overshadowed by Airbus’ wins.

Is Boeing going?

When SpiceJet can expect its 737 MAXs, and what the 42 airplane order speaks

-8, 42, 737, Boeing, Investor, MAX, Orders, Spicejet

VT-SPW-KarthikThough not officially acknowledged by the airline, SpiceJet has reportedly placed an order for 42 Boeing 737 MAX Aircraft. Considering the airline’s fleet to be comprised mostly of Boeing 737-800s, the order may very well be entirely made of Boeing 737 MAX 8 airplanes.

The Boeing 737 MAX 8 is expected to enter service in the third quarter of 2017, almost 4 years from now. With already 1,763 orders for the 737 MAX airplanes, it may be easily close to 2-3 years after the 737 MAX 8 enters service that SpiceJet receives its first 737 MAX, assuming that Boeing will up the production rate of the 737 jets to 47 a month, or higher to 60, from the present 42.

SpiceJet is now one of 298 yet “Unidentified” Customers who have ordered 737 MAX airplanes. The airline is yet to receive 18 Boeing 737-800 airplanes from the US airplane manufacturer. In 2013, SpiceJet received 10 Boeing 737NG airplanes, its highest ever in a calendar year.

This order that speaks of an airline poised for growth 5 years down the road, is a precursor to “something” big in the airline. Note the 737NG delivery trend for SpcieJet, below, and you’ll notice that 2013 was a very happening year, for an airline about to make a big announcement in 2014: the news of the much awaited investor.

737 Production Ramp Up, and how it compares with the A320’s

Boeing737_ProductionJust when the 747-8’s production rate was ramped down at its Everett facility (state of Washington), Boeing announced that the 737’s production rate will be ramped up at its Renton, Washington facility , from its existing 38 airplanes per month, to 42 per month in the first half of 2014, and next 47 airplanes per month in 2017, the highest rate ever for its best-selling airliner. Boeing currently has more than 3,400 unfilled orders across the 737 family, which includes the 737Max.

Airbus, in contrast, has 4,223 unfilled orders across the Airbus A320 family, which includes the A320NEO. Across its global production facilities, Airbus already produces 42 airplanes a month since 2012, the highest-ever rate for any commercial aircraft, and has no immediate plans for a production ramp up over concerns of supply chain fragility.

The A320 Family is produced on two Airbus assembly lines in Europe: Toulouse, France and Hamburg, Germany; which have been complemented by an additional facility in China.  Toulouse is home to the initial assembly line, building A320s; Hamburg has responsibility for the A318, A319 and A321; while Tianjin assembles A319s and A320s.

Tianjin is Airbus’ first assembly facility located outside of Europe, resulting from a joint venture involving Airbus with a Chinese consortium comprising the Tianjin Free Trade Zone (TJFTZ) and China Aviation Industry Corporation (AVIC).

Joining this network will be a new A320 Family production facility in Mobile, Alabama USA, which is to build A319, A320 and A321 jetliners beginning in 2015.

Boeing, however, produces the Boeing 737 only at its Renton facility.

There is a buzz about the PW1100G  Geared Turbofan Engine from Pratt and Whitney, that will power the first A320NEO. The PW1100G is a family of ultra-high bypass engines, part of the PW1000 series. The Flying Engineer welcomes you to enjoy the most technical take on the engine, that will leave you either educated, or snoring on your chair. Grab that coffee, and appreciate the next big thing in jet transport as we know today: Geared Turbofan Engines.

In this article, we explore, at a high level, the design of the PW1100G family, how it compares with existing A320 engines, the differences, on a high level, of this family with the competitor’s offering: the LEAP 1A, why the Boeing 737MAX family doesn’t need such a large turbofan engine, and finally, before concluding, the pros and cons of such an engine.
