What the Aviation Industry's Avionics Shift Means for Airlines, Lessors and MROs
A conversation with Neil Day, General Manager of VHR Aircraft Technical Services
Something unusual happened at ISTAT Americas 2026. A conference traditionally dominated by lessors, financiers and aircraft appraisers, avionics took centre stage, not as a compliance issue, but as a primary driver of aircraft value and lease rates. The shift sparked significant discussion across the industry.
We sat down with Neil Day, Divisional Director of VHR Aircraft Technical Services, to break down what the ISTAT conversation actually means, what solutions are now being deployed, and what airlines, lessors and MROs should be thinking about right now.
The Question: For anyone who missed the ISTAT Americas coverage, what was the headline from a technical perspective?
The short version is that avionics has moved from being a compliance objective to being a commercial variable. For a long time, when you were valuing or leasing an aircraft, you looked at airframe hours, engine cycles, and maintenance status. The physical condition of the asset. What ISTAT 2026 spoke about is that digital capability, specifically whether an aircraft's avionics can be upgraded, integrated, and kept current with evolving airspace requirements, is now being priced into lease rates and residual values. That is a shift to consider thinking about, and from where I sit, dealing with modification programmes day to day, it makes complete sense. We've been seeing the demand for this work build for a while. ISTAT just pushed this further into the light.
What's driving it? Why now?
A few things are converging at once. First, OEM delivery backlogs are significant. Airlines that were expecting new aircraft on a certain timeline are now operating their existing fleets for longer than planned. So instead of getting a brand new, fully connected, open-architecture aircraft from the factory, they're looking at their current fleet and asking, how do we extract more value from what we have?
Secondly, engine maintenance queues are being stretched, as we know. There's real pressure on MRO capacity globally, and that's causing further delays in fleet transitions. So again, operators are holding the aircraft for longer.
When you're holding an aircraft for an extra three, four, or five years beyond your original plan, the economics of investing in an avionics upgrade change completely.
What previously might have seemed like an expensive modification with a long payback period suddenly becomes very sensible.
The ISTAT article talked specifically about open-architecture avionics systems and software-defined flight decks. Can you explain what that actually means in practical terms?
Historically, avionics systems were proprietary and closed. If you wanted to add a new capability, navigation, or different connectivity platform, you were often looking at a significant hardware replacement. That's costly, it takes the aircraft out of service, and it requires a full certification process for each change.
Open-architecture systems flip that model. The hardware is designed to accept software updates and new modules without a full rip-and-replace. It's closer to how you'd think about a smartphone; the underlying platform stays, the capability evolves through updates.
For an airline or a lessor, that changes the risk profile significantly. An aircraft with an open-architecture avionics suite isn't just valuable today. It has a credible pathway to staying current for five to ten years from now. That's what's getting priced into valuations.
What specific programmes and modifications are operators actually investing in right now?
Wi-Fi and connectivity installations are probably the most visible right now. I’ve done a significant amount of this work, A320, A330, B737, B777 installations, and the demand has been consistent and growing. Airlines understand that passenger connectivity is no longer a differentiator; it's becoming an expectation. But beyond the passenger experience angle, these installations also open up the aircraft's data environment. Once you have reliable connectivity, you can start pulling real-time operational data. Aspects like engine performance, fuel burn, and systems health into airline operations centres. That data has real value for maintenance planning and cost management.
IFE replacement is another active area, A330 and B777 in particular. Avionics upgrades on platforms like the Sikorsky S92, King Air Garmin upgrades, AWACS modifications on B777 and ATR 72-600, there's a broad spectrum of work. It's not just commercial widebodies. The demand is across platform types.
We can also look at NPAS incorporation on rotary wing, Loom and harness manufacture & Avionic component assembly. These aren't exactly the most glamorous programmes, but they're critical, and they require a very specific type of engineer to execute them correctly.
The ISTAT article mentioned the monetisation of operational data. Is that a real conversation operators are having, or is it more forward-looking?
It's both, to be honest. The infrastructure conversation is very real and happening now. You have to think about getting the aircraft connected & getting the data flowing & so on ... The full monetisation of that data is still maturing, but the direction is clear. Airlines that invest in connectivity infrastructure now will be in a position to exploit it as the analytical tools develop. Those that don't will find themselves retrofitting later, at greater cost, potentially under regulatory pressure, and with older assets that are harder to work with.
What I'd say to any operator is that the connectivity modification is the enabling step; everything else builds on it.
What about lessors? The ISTAT coverage suggested they're starting to treat avionics upgrades as capital improvements rather than maintenance costs. What does that mean operationally?
It means lessors are increasingly involved in the decision to modify, not just the decision to lease. If an aircraft without a clear upgrade pathway faces steeper residual value discounts, a lessor has a strong incentive to invest in that upgrade proactively, to protect the asset value before the aircraft goes back on the market.
Historically, the airline or the MRO was typically the commissioning party for modification work. Increasingly, lessors are coming into that conversation, sometimes funding modifications directly, sometimes specifying them as a condition of lease placement.
It's a positive development for the industry overall; it creates a stronger commercial incentive for keeping fleets current.
What does this mean for MROs? There's an opportunity here, but are they set up to take it?
The opportunity is real and the pipeline is building. But there's a very specific challenge that comes with avionics modification work that not every MRO facility is set up for.
This isn't generalist line maintenance. Avionics modification is STC-specific, certification-heavy, and deeply dependent on having the right engineers in the right positions. You can't put a B1 line technician who's spent their career on scheduled checks into a Wi-Fi installation programme on a B777 and expect it to run smoothly. The knowledge base is different, the documentation requirements are different, the interface with the design organisation is different.
The MROs that are winning this work are those who have built or can rapidly access specialist capability. Speed to resource matters, customers are operating on tight timelines, aircraft need to be back in service, and programme delays are expensive. The ability to bring in qualified, vetted, immediately productive avionics engineers is often the difference between winning a contract and losing it.
That's where VHR Aircraft Technical Services comes in. Can you talk about what the business actually does in this space?
VHR Aircraft Technical Services operates as a project solutions partner for airlines, MROs and manufacturing companies across the full spectrum of aircraft modification and manufacturing work. We're not a traditional staffing agency, we manage programmes, provide fixed-price solutions, and take accountability for delivery.
On the avionics and modification side specifically, we have real hands-on experience. A320, A330, B737, B777 Wi-Fi installations. IFE replacement programmes. Major avionics upgrades on rotary wing platforms, including the Sikorsky S92, CH47. NPAS incorporation on Airbus H135 and H145. AWACS modification and installation work. Avionic component assembly and loom manufacture.
We operate from offices across Europe, the Middle East and North America, UK among others, and we're structured to be compliant wherever we're working, whether that's FAA, EASA, or regional authority requirements.
What differentiates us is that our people come from aviation. The team leading this work has genuine engineering backgrounds. I came up through a MOD apprenticeship, worked across military and commercial platforms, and have spent the majority of my career in complex modification and repairs environments. That understanding of what good delivery looks like from a technical perspective runs through everything we do.
What would you say to an airline or MRO director reading this who's thinking about their modification pipeline for the next eighteen months?
Start the conversation now. The lead times on specialist avionics resources are longer than most people expect, particularly for programmes that require specific STC knowledge or regulatory approvals in certain jurisdictions. If you're planning a connectivity installation programme for later this year, you should be having conversations about resourcing today, not in Q3.
The market signal from ISTAT is clear: this work is accelerating. Airlines are investing, lessors are investing, and the pool of engineers with the right experience to execute it is not growing at the same pace. That imbalance will get more pronounced before it gets better.
The operators and MROs that move now will have an advantage, both in terms of securing the right talent and in terms of their aircraft being on the right side of the valuation gap that's opening up.
Last question, the ISTAT article ended with the line "that's a different kind of durability. It's not measured in cycles or hours. It's measured in code." Does that resonate with you?
It does. And I'd add one thing to it. Code needs people to write it, certify it, integrate it, and install the hardware that carries it. The physical work of putting these systems onto aircraft doesn't disappear because the value is digital. If anything, it becomes more demanding because the technical standard required to execute certified avionics modifications is high, and there is no tolerance for error.
Steel still matters. The people who work on it matter just as much.
