Cut taxi time.
Save the fuel.
Hand the events to ATOMS.

Airfield-movement optimisation. Fuses surface radar, MLAT, A-CDM, and the ATOMS turnaround stream. Surfaces congestion hot-spots, predicts taxi time per gate–runway pair, nudges TSAT 30–90s so the aircraft meets the gap, not the queue. 10–20% taxi-time reduction; fuel + CO₂ on the same dashboard.

◆ THE PROBLEM ECONOMY
TAXI-TIME IS THE FUEL LINE
NOBODY SEES THE WHOLE NETWORK

Narrow-body burns ~8–15 kg/min at taxi idle. A hub runs 1,000+ movements a day. The spread between best and worst cycle on the same route can be a sector's fuel bill. Taxi time is the cleanest fuel saving — invisible because nobody watches the network, only the single radio call.

◆ TYPICAL TAXI BURN
8–30kg/min
Fuel burn at taxi idle — narrow-body lower, widebody higher. Every minute saved compounds across every movement of the day.
◆ AVERAGE TAXI CYCLE
15–25min
Out plus in, per flight, on a busy hub. The variability between best and worst on the same route is often the optimisable spread.
◆ ACHIEVABLE REDUCTION
10–20%
Operating outcome NorthSky targets and characterises during the survey window — once the network has memory and the AI has a few weeks of priors.
◆ DAILY VALUE
hundredsof t CO₂
Tonnes of CO₂ avoided per day at a large hub, plus equivalent fuel cost — surfaced on the same operating screen the tower runs.

◆ OPERATIONAL CHANGE
WHAT THE TOWER GAINS
WHAT THE AIRLINE GAINS
◆ TODAY · STATE-OF-PRACTICE
A single radio call. No network view.
  • Pushback on gate's schedule, not what the taxi network can absorb.
  • Aircraft idle at the holding point — fuel burning, crew clock ticking.
  • Congestion hot-spots known to controllers, unknown to the airline.
  • Sustainability uses fleet-wide average, not per-flight measurement.
◆ WITH AEROTAXI
A network. Predicted. Nudged.
  • TSAT advised — pushback nudged 30–90s so aircraft meets the gap, not the queue.
  • Per-flight VTT published to airline before pushback.
  • Hot-spot heatmap — duty controller sees where the network is bleeding minutes.
  • Events streamed into ATOMS — gate-to-gate record continuous.

◆ THE THREE LAYERS
INTAKE · INFERENCE · ACTION
LAYER 01 · INTAKE

We collect.

Every signal that touches the surface

SMR for position; MLAT for tail attribution; A-CDM for intent; ATOMS for the pushback event; weather, schedule, runway config — all time-aligned on one clock.

LAYER 02 · INFERENCE

The AI learns.

Models that get better every shift

Congestion model learns where the network bleeds time. VTT predictor publishes expected taxi duration per gate–runway pair. TSAT advisor nudges pushback so the holding point is met at the gap.

LAYER 03 · ACTION

We emit events.

Into the operating record

Each inference is a structured event on the ATOMS bus. Tower sees the advisory. Airline sees per-flight VTT before pushback. Sustainability officer sees per-movement fuel + CO₂ saved.

◆ OUTCOMES
AIRPORT · AIRLINE · ENVIRONMENT
◆ THE AIRPORT GAINS
Throughput, without concrete.

Every minute pulled out of the average cycle is a minute back on a slot, every shift.

  • 10–20% taxi-time reduction on the average cycle.
  • Hot-spot visibility the duty controller did not have before.
  • Sustainability evidence — per-movement, audit-ready.
◆ THE AIRLINE GAINS
Fuel saved. Per tail. Every day.

One of the cleanest sustainability wins in the airline P&L — no new aircraft, no new SAF.

  • Per-flight fuel saved attributed to each tail.
  • Per-flight CO₂ avoided for sustainability / CORSIA.
  • Predictive VTT — block fuel decisions get tighter.

Common questions.

◆ FOR TOWER, AOCC & AIRLINE OPS
WRITTEN FOR PROCUREMENT

Do we need ATOMS to run AeroTaxi?

No. Standalone. With ATOMS, taxi events land on the same bus as turnaround events and the record is continuous gate-to-gate.

Will this conflict with our A-CDM platform?

No. Reads from A-CDM and emits TSAT advisories as suggestions, not commands. Watch manager accepts or overrides. Acceptance climbs to 85–90% in a few weeks.

How long until we see the 10–20%?

Congestion model needs a few weeks of priors. TSAT advisory becomes useful in the first month. Full 10–20% characterised during commissioning against your baseline.

How is the fuel / CO₂ attribution audited?

Per-flight fuel against a published baseline; CO₂ via IATA 3.16× factor. Methodology signed off during commissioning; every saving traceable to the underlying taxi events. Trust Center →
