Six weeks ago I wrote that the gap between airline intent and airspace capability is where inefficiency lives.

Over the weeks since, I've tried to show you what closing that gap actually looks like — not as a concept, but as a working system with a track record.

AFOS, embodied in SMARTSlot® and developed with SMART Aviation Solutions Ireland, has already:
— Flown 655 live sorties across Europe and Asia-Pacific
— Saved up to 8.5 minutes per sector on the Dublin–Gatwick route
— Achieved sub-30-second arrival precision on 47% of Aer Lingus flights under heavy ATC intervention
— Modelled up to 60% CO₂ reduction in the approach phase
— Operated with 98%+ automated communication reliability across 310 JetStar Japan missions

That's not a pitch deck. That's a programme of work.

The Seamless Skies for All shortlist has been a platform. What comes next is the work that matters.

If you're an airline and want to understand where your systematic efficiency losses are occurring — and what a structured optimisation programme looks like — I'd welcome a conversation.

If you're an ANSP or network manager exploring how machine-readable airline intent could reduce tactical coordination burden — let's talk.

If you're an airport, investor, or technology partner interested in the commercial and environmental case for AFOS — Straten CSL and SASI are an active conversation.

The aviation system is extraordinarily good at what it does. AFOS is about making it better.

To be shortlisted for Seamless Skies for All is an honour. To see who we're listed alongside makes it even more meaningful.

The other shortlisted entries represent some of the most ambitious initiatives in global airspace management today:

NASA Air Traffic Management eXploration (ATM-X) — pushing the boundary of high-altitude traffic management and collaborative evaluation at a scale that only NASA can operate. The ambition is extraordinary.

DFS Deutsche Flugsicherung — developing the operational ATCO model for drone integration in controlled airspace. One of the most practically complex challenges facing European ANS right now.

EUROCONTROL — managing Europe's busiest summer through network collaboration. The data behind that initiative represents an operational achievement that the wider industry depends on but rarely sees.

ENAIRE — building an integrated digital ecosystem for airspace coordination. The kind of infrastructure investment that makes everything else possible.

And Straten CSL, with AFOS and the SASI SMARTSlot®: a practitioner-led, data-validated system that has already flown 655 live sorties across two continents — and proved that the missing layer between ATFM and A-CDM is not a theoretical concept.

What strikes me about this shortlist is the breadth of the challenge it addresses collectively. Infrastructure. Operations. Regulation. Efficiency. Each entry is a different lens on the same problem.

That problem is making the skies work better — seamlessly — for everyone who uses them.

Whatever the outcome, being part of this conversation is a privilege. The sector is moving. Straten CSL intends to move with it.

Which of these initiatives are you following most closely?

Anyone can model a theory. The question that matters is: what happens in the real sky, with real ATC, real weather, and real constraints?

We ran AFOS in the real sky. Twice.

Trial 1: Dublin – London Gatwick 105 live Aer Lingus flights.

97% of those flights experienced ATC-directed routing changes from their filed flight plan — demonstrating that we were testing the system under genuine operational pressure, not benign conditions.

Despite that, 47% of flights arrived within ±30 seconds of the SMARTSlot® Required Time of Arrival. 89% of randomly selected crews confirmed accuracy within ±1 minute.

The direct-routing time saving reached up to 8.5 minutes per sector. Fuel saving per A320 flight: €560. Annualised at 80% deployment across one-way services: €800,000.

Trial 2: Tokyo Narita – Fukuoka 550 JetStar Japan flights. Deployed on Oracle iCloud in real time.

Of 310 flights where the RTA was applied without ATC interference, average deviation was ≤15 seconds. Best-case performance: ≤10 seconds. Automated communication process reliability: 98%+.

These are not projections. They are validated outcomes from 655+ live flights, logged against airline records and verified with ADS-B data.

Arrival predictability improved by more than 80%. And we modelled up to 60% CO₂ reduction in the approach phase on the Japan trial.

AFOS works. The data says so.

What questions do you have about the trial methodology or results?

Following detailed engagement with the CAA's Safety & Airspace Regulation Group on the Windfarm project, Straten CSL has obtained formal written policy clarification from the CAA on the application of CAP 764 Edition 7 to wind energy safeguarding assessments.

The CAA's response — spanning 14 policy questions — confirms several principles that developers need to know:

✅ A binary "acceptable / unacceptable" ANSP response is not sufficient under CAP 764
✅ Technical effects alone cannot justify a safeguarding objection — operational significance must be demonstrated
✅ In low-density Class G airspace, the evidential burden on ANSPs is higher, not lower
✅ Developer-led traffic studies and operational assessments are formally recognised as valid evidence
✅ VRPs and VFR routes do not imply a requirement for continuous radar surveillance
✅ Where operational impact is low, CAP 764 supports light-touch or no mitigation — and non-objection

This clarification has material implications for how safeguarding objections can be challenged and how operational impact assessments should be structured.

If your wind energy project is facing disproportionate or inadequately evidenced aviation objections, we'd welcome a conversation about how Straten CSL can support your assessment.

Reactive operations are expensive. Every holding pattern, every late slot change, every fuel-heavy recovery manoeuvre represents a failure of anticipation.

AFOS was designed around a different principle: that if you give an airline continuous situational awareness and a real-time negotiation channel, it stops being a passenger in its own operation.

The mechanism is a four-stage closed loop we call PDNE:

1. Predict — AFOS continuously anticipates airspace, weather, and airport constraints using i6D trajectory modelling: six-dimensional flight data covering track, altitude, speed, time, weight, and weather simultaneously.

2. Decide — The system computes the most efficient slot and trajectory combinations in real time, not after a CTOT has already been issued.

3. Negotiate — Optimised flight intent is exchanged with ATFM and A-CDM systems via machine-readable protocols — SWIM, FF-ICE, DPI/FUM — so that the conversation with the network happens before the constraint becomes a problem.

4. Execute — The solution is applied operationally and monitored continuously. If deviation exceeds 30 seconds, the system dynamically recomputes. Post-flight, outcomes are validated against the model.

This cycle runs continuously, for every flight, throughout the entire lifecycle from departure planning to wheels-down.

No hardware on the aircraft. No ATC system changes. No software deployment at the airport. Cloud-native — stakeholders connect via URL.

The PDNE loop is what separates AFOS from a planning tool. It's an operating system for the flight itself.

What would continuous situational awareness across ATFM and A-CDM change for your operation?

Aviation has two world-class systems for managing flights. Neither of them belongs to the airline.

ATFM — Air Traffic Flow Management — regulates demand and capacity across the network. A-CDM — Airport Collaborative Decision Making — coordinates ground operations at the airport. Both are mature, proven, and essential.

But between the sky and the ground, there is a gap. Airlines sit at the centre of every operation yet remain the most reactive participant in the system — dependent on CTOT slots they didn't negotiate, holding patterns they can't anticipate, and ground delays they couldn't predict.

That gap has a name now: AFOS.

The Airline Flight Optimisation System is not a reinvention of ATFM or A-CDM. It is the bridge between them — an airline-centric intelligence layer that unifies trajectory intent, slot management, and real-time collaboration into one continuous loop.

Together, ATFM, A-CDM, and AFOS form what we call the Collaborative Operations Triad:
- ATFM manages the sky.
- A-CDM manages the ground.
- AFOS manages the flight between them.

Developed by SMART Aviation Solutions Ireland, AFOS is embodied in SMARTSlot® — the world's first operational AFOS platform.

Next week, I'll explain the engine that drives it: a four-stage closed loop that transforms reactive airline operations into predictive ones. Where do you see the biggest disconnect in today's airline–ANSP collaboration?

14/04/2026

Every day, thousands of tonnes of fuel are burned on routes that don't need to be flown.

Not because of weather. Not because of traffic. Because the systems connecting airline intent with airspace capability weren't designed to talk to each other in real time.

I spent 25 years as an operational air traffic controller — watching this disconnect from the inside. The controller sees the sky. The airline sees the schedule. The gap between those two views is where inefficiency lives.

AFOS — the Airline Flight Optimisation System — was built to close that gap.

It's not a theoretical framework. It's a practical, data-driven tool designed by people who understand what "operationally feasible" actually means at the sharp end of ATC.

Over the next six weeks, I'll be sharing what AFOS does, how it works, and why Straten CSL is proud to have it shortlisted for the Seamless Skies for All award — alongside NASA, EUROCONTROL, DFS, and ENAIRE.

The skies are full of potential. We're here to help unlock it. What inefficiency in airspace management frustrates you most? I'd welcome your perspective in the comments.

Today’s RenewableUK – Wind, Aviation & Defence event at the RAF Officers’ Club, London, was an extremely well-run and engaging forum, bringing together a broad mix of stakeholders from across renewables, aviation, and defence. The discussions were constructive and solution-focused, reflecting the growing maturity in how we collectively address the interface between wind energy and aviation/defence requirements.

It was also great to reconnect with many colleagues, clients, and industry peers.

And a special mention to the venue itself — the RAF Officers Club is an impressive setting. An amazing backdrop for an important industry conversation.
