Signol
Signol, a London company founded in 2017, uses behavioural science and data to encourage pilots to take fuel-saving actions.
It grew out of academic research with Virgin Atlantic, where its approach saved about 1,000 tonnes of fuel over six months. It reports savings of about 264 kg of fuel per flight. AI is one component alongside its behavioural core; other customers are not named.

Products & Solutions
1 productSignol Aviation Platform
A SaaS platform combining behavioural science and data analytics to encourage pilots and cabin crew to adopt fuel-saving operational behaviours.
Reduces airline fuel consumption and CO₂ emissions by influencing pilot and crew behaviour through personalised performance feedback, goal-setting, and anonymised peer comparison, without requiring changes to aircraft systems or flight planning infrastructure.
- Personalised per-flight fuel-efficiency feedback delivered to individual pilots via app and email
- Anonymised peer benchmarking against other pilots on the same fleet
- Goal-setting and behavioural nudge techniques drawn from academic behavioural economics research
- Private, secure pilot dashboards showing individual fuel and CO₂ KPIs
2 more features
- Manager-level analytics dashboard showing fleet-wide savings without revealing individual data
- Integration with airline flight data monitoring (FDM) and fuel management systems
Technical specifications (3)
- Cloud SaaS with no aircraft hardware requirement
- Integration via airline FDM and fuel management data feeds
- Pilot-facing mobile app and email delivery
Register notes
Notes held in the Aerostack register. Aerostack has not independently verified them.
Signol occupies an unusual position in aviation sustainability: its intervention is entirely behavioural rather than technical, requiring no changes to aircraft, avionics, or operational infrastructure.

This lowers the adoption barrier considerably compared with hardware or flight planning software changes.
The commercial model builds on a 2016 peer-reviewed academic study with Virgin Atlantic and University of Chicago economists, giving it an evidence base that most aviation AI startups cannot match.
Growing regulatory pressure on airline CO₂ reporting (CORSIA, EU ETS) increases the relevance of demonstrable, auditable per-flight savings.
The Virgin Atlantic deployment, saving approximately 1,000 tonnes of fuel over six months, is one of the most cited documented outcomes in aviation behavioural sustainability.

At a per-flight level, the reported 264 kg fuel saving and 837 kg CO₂ reduction are meaningful at scale: across a mid-size airline network, behavioural nudging alone could represent a significant fraction of voluntary emissions reduction targets.
