Passengers, airline and airport staff see IT moving at warp speed on the ground. So when will we see more of it onboard aircraft?

Aircraft have been connected and digitalized for decades. They’ve had to be, to fulfill safety and regulatory requirements.

To do the job, SITA’s solutions have been developed over time to support airline operations, air traffic services and government needs.  

Passenger demands

Now, the recent acceleration towards aircraft digitalization comes with the ambition of airlines. For one thing, they’re eager to respond to passenger demand and ever growing requirements for connectivity.

That’s because passengers increasingly expect access to data wherever they are. With most people checking their mobile phone 150 times a day, it’s hardly surprising.

On top of that nearly a quarter of Facebook’s 1.15 billion or so users check their accounts more than five times daily. And over four billion people now access social media sites using their mobile devices.

Operational drivers

But it’s not just the passenger focus that’s driving aircraft digitalization. It’s also the industry’s ambition to optimize aircraft related operational processes, and to reduce maintenance costs.

Air framers and OEMs (original equipment manufacturers) are playing a part, as they strive to reinforce their presence in the service segment and the provision of ‘fly-by-the-hour’ type programs.

The point is, ubiquitous aircraft connectivity en-route and on the ground has generated high expectations. So why has digital technology been slower to make inroads onboard?

‘Nose-to-tail’

The answer is simple. Complexity. The talk in air transport today is about ‘nose-to-tail, air-to-ground aircraft data exchange’.

That involves everything from connections in the cockpit and cabin, to communications for ground crew, pilots, MROs (maintenance and repair operations) and passengers – along with multiple stakeholders such as Air Traffic Control and airline operational control centers, to name a few.

“The future of ‘connected aircraft everywhere’ is inevitable,” says Gregory Ouillon, who heads up SITA’s e-Aircraft program.  

“But airlines putting into place an aircraft digitalization strategy need to make some critical decisions.

“On top of the choices, there’s the need to achieve the right cost-benefit ratios to justify the business case for e-enablement.

“The transformation is happening, though the reality is that it will take time for widespread adoption of the fully connected aircraft,” he adds.

Right application?

Those critical decisions involve choosing the right aircraft communications, applications and services so that airlines can protect current aircraft digitalization investments.

Airlines with mixed fleets, for instance, need to bear in mind that new generation aircraft designs restrict choices in the implementation of Electronic Flight Bags (EFBs) and broadband communications. That prevents a common approach.

Another factor is whether to wait for higher capacity next-generation systems. The industry buzz is around GlobalXpress – Inmarsat’s new Ka-band 12 megabits per second solution.

December 2013 saw the first satellite launched, with others to follow. It’s the first time cockpit and cabin communications have come together in a single technology.  

“Everything passengers can do on the ground with their tablets and smartphones, they will want to do in the air,” says Ian Dawkins, CEO of OnAir, which is one of only a few Inmarsat licensed distributors for the new Ka-band solution.

“We’re finding that today’s passengers want more than just in-flight entertainment (IFE). They want a completely connected travel experience: pre-flight, in-flight and post-flight.

“In-flight passenger GSM and Wi-Fi connectivity are here to stay,” he says.

Right mobile path?

Then there’s the choice of mobile platform for cabin crew and ground staff. Apple iPads, Google Android devices or Microsoft Surface?

They each have different approaches to ‘app stores’ and mobile networks, as well as to remote device management for airline staff applications.

And each is fighting hard for traction in the air transport industry (see ‘Tablet choices – which way is your airline heading?’).

Charting the course

So how can an airline that would like to engage or accelerate an aircraft digitalization strategy chart the right course?

“Based on lessons we’ve learned with airline customers,” says Ouillon, “our recommendations would be to look at all the capabilities needed, paying close attention to the ability to integrate solutions and to achieve secure data distribution.

“Our own experience with customers has led us to create a new e-Aircraft Program as well as release an evolving portfolio of e-Aircraft services that aims to eliminate the risks associated with aircraft e-enablement.”

“This is part of SITA’s mandate is to support the air transport industry’s aircraft digitalization while maintaining complete neutrality,” he says.

‘e-Aircraft portfolio’

The e-Aircraft portfolio will address requirements in-flight en-route (flight deck, cabin and aircraft health monitoring), as well as on the ground, providing value-added and secure aircraft data management and total aircraft connectivity.

The program supports a number of airline digitalization requests, with the first modules including CrewTablet, Electronic Flight Bag (EFB) and e-enablement solutions.

This will help airlines, air framers and OEMs to introduce e-aircraft services through a simpler, more reliable and cost effective technical and service framework en-route and at airport/in hangars.

One-stop

“Created around four families of services – passenger, crew management, flight operations, and aircraft health and maintenance – the initiative brings together previously distinct service areas into a consistent and modular portfolio,” says Ouillon.

That allows a ‘one stop shop’ approach for e-enabling any aircraft type – whether line-fit or retro-fit – for any aircraft related process/functional domain both en route and at the airport.

Modularity

Aircraft digitalization demands flexibility in integrating solutions. That’s because whatever airlines already have in place, further building blocks of their aircraft digitalization strategy will need to be integrated in order to transition their processes.

It also demands in–depth knowledge across the range of services. “Having the know-how in place to design mobile communications solutions for the cabin, while also e-enabling the cockpit, is essential,” Ouillon adds.

EFB implementation requires a study of all nose-tail processes fed by paper, followed by the deployment of devices using modules to make that paper redundant.

Devices such as EFBs in the cockpit and tablets in the cabin can begin by loading data such as charts and passenger lists before flights. To generate maximum benefit they must use industrialized application interfaces to connect, in-flight to back-office systems, with fast and reliable synchronization.

This allows for automation of processes such as technical logs that indicate any needs for repairs of aircraft facilities such a seats. The crew tablets can automatically update duty free inventory and access real time credit card authorization.

Secure data

New generation aircraft generate vast amounts of data, from the aircraft to the ground and to applications. They are driving demand for secure and fast high bandwidth connectivity at the gate, to capture data from EFBs, cabin crew tablets, IFE and flight operations.

These aircraft promise cost-effective data capture and processing in real-time, with new processes and new ways of working.

“The data they generate needs to be captured, stored securely, and then accessed and manipulated rapidly to be used in real-time, for engine maintenance, analysis of fuel burn and much more,” says Ouillon.

The aircraft digitalization process must ensure the secure distribution of that data. “Thanks to the ability to connect to aircraft, to airlines and to the VPNs of the manufacturers, the secure distribution of data is integral to SITA’s approach,” says Ouillon.

Big impact

As next generation aircraft take to the skies, SITA is also facilitating ground connectivity throughout airports worldwide, leveraging established communication infrastructures, such as Airport Hub and the Air Transport Industry (ATI) Cloud.

Both are seeing rising interest as new aircraft are introduced.  (See ‘A revolution at the gate’.)

The next step is to put into place the big data brokerage and business intelligence capabilities to distribute and process data securely across the entire ecosystem – for engines as much as for In-Flight Entertainment (IFE).

In the meantime, as increased travel drives collaborative flying, the demand for automation and connectivity will rise. Fast access to big data will be critical to airlines and air traffic control as they collaborate to determine guaranteed flight plans, accuracy and connections.


Cost-benefit

The process of aircraft e-enablement is throwing a spotlight on cost-benefit ratios. The promised benefits of deploying cockpit and cabin connectivity must offset the costs of changing from legacy operations and systems.

OnAir’s Dawkins is on record as saying the inevitability of connectivity on-board is not just because of its potential as a revenue earner.

“On-board connectivity has massive potential value as an essential tool for crew, maintenance and engine manufacturers, as well as for the airline and all those connected with the aircraft, to ensure it operates effectively and efficiently.”

He likens the scenario to a Formula One car, connected from every race track in the world via hundreds of sensors to the company's factory, as well as to the engine manufacturer and other key partners.

“Total, constant monitoring – with real-time visibility and control – offers significant scope for saving money and for driving up customer service, increasing operational efficiency and enhancing aircraft maintenance,” he says. “This alone should help airlines justify adoption of onboard connectivity.”

No going back

Boeing and Airbus predict a huge rise in next generation connected aircraft over the next 10 years, as the trends drive the industry towards inevitable onboard connectivity.

And whether it’s for better flight safety, increased uptime, fuel savings, improved maintenance and operations or an enhanced passenger experience – the benefits are clearly there to be realized.

But there’s no doubt that progressing along the e-enablement path involves a complex transition, one which is well beyond most airlines’ comfort zones.

“While no one can claim to have all the answers today, expert insight is needed into all the processes and sophisticated technologies that enable nose-to-tail connectivity,” says Ouillon.  

“For SITA’s part, with a mandate to offer neutrality in aircraft e-enablement, we’ll be working with the air transport industry to reap the benefits of an automated aircraft ecosystem.”

e-Aircraft program

To release a portfolio of e-aircraft services for the industry, SITA and OnAir have jointly created an ‘e-Aircraft Program ’.

 

The program is focused on the flight deck, cabin and cockpit en-route – as well as activities on the ground, while providing value-added aircraft data management and total aircraft connectivity.

 

The initiative marks a first in the industry by bringing into a consistent and modular portfolio services for passengers, crew management, flight operations and aircraft maintenance.

The portfolio will help airlines, air framers and OEMs to introduce e-aircraft services through a simpler, more reliable and cost effective technical and service framework en-route and at airport/in hangars.

 

First modules

The first e-Aircraft portfolio modules were released in 2013. They included CrewTablet (see page X) and Electronic Flight Bag (EFB) solutions. The program has supported a number of airline requests for the e-enablement of next generation aircraft – including B-787 and A-350 – which is part of the priority roadmap for 2014.

 

E-enablement securely links next generation aircraft at the gate with cloud-hosted applications globally through different communication methods – serving airline flight operations and performance, aircraft maintenance, and in-flight entertainment globally.

Air framers are also seeking help from the program in building the technical and operational framework supporting next generation aircraft global customer service strategies, both en-route and at the airport.

 

Opportunities

The program reflects opportunities arising from the coming together of different areas of activity – where airlines, air framers and OEMs can connect passengers and systems, optimize aircraft processes and save costs – while promoting SITA’s spare parts management and Software-as-a-Service (SaaS)-based maintenance planning solutions.

 

Next in the program is the development of value-added solutions further leveraging cabin and cockpit data, based on close collaboration with airlines, air framers, OEMs and industry third parties.
