What Are We Doing?
Existing AGL system at HeathrowUsed for visual indication to pilots and other users of ATC instructions (ground movement)Controls access to the runway“Follow the Greens” route assistance to pilots
Control System requires replacementExisting AGL luminaires & block control retainedRequired for business resilience

Heathrow Strategic Partnership
HAL and NATS signed a Partnership Agreement in April 2015.jointly created a long term business partnership with
shared objectives aligned to what Heathrow is seeking to deliver performance led
in areas
such as delay, service resilience, safety and aircraft noise reductiondrives year on year performance improvement through innovations in service and technology Set up a Partnership Joint Project to replace GMCS/AGLPage 6Slide7
New Approach
Single Cross-Organisational Project TeamDevelopment of single ‘End to End’ Risk SchemeDirectly linked to Aircraft ConsequenceCatastrophic
Minor (EASA CS-25.1309)Single Integrated E2E Hazard IdentificationSeverity Assessment
Layers of Protection AnalysisPeople (Pilot / ATCO /LPO) - these are the only independent layers
EquipmentProceduresBuilding an understanding of Pilot BehavioursDirect Input to Hazard IdentificationSurvey of PilotsE.g. Positive Expectation Bias ‘Lit Greens ≡ ATCO Intent’Page 7Slide8
Holistic Design
True understanding of AGL in Service DeliveryWhat is the system protecting?How is it actually used by Pilots / Drivers?How is it used by LPOs? How is it used by ATCOs
? Known operational and functional shortcomings in existing system?
What is existing system designed to deliver?
