- 1. Aeronautical Ground Lights ForAir Traffic Controller Training Center Mumbai Airport
- 2. Introduction • Aeronautical GroundLights (AGL) are visual aids installed at aerodromes to assist pilots and air traffic controllers in safe aircraft movement during night and low visibility operations.
- 3. Purpose of AeronauticalGround Lighting • • Safe landing, take-off, and taxiing • • Guidance during night and poor visibility • • Runway and taxiway identification • • Obstruction marking • • Compliance with ICAO & DGCA standards
- 4. Regulatory Standards • •ICAO Annex 14 – Aerodromes • • DGCA CAR Section 4 – Aerodromes • • FAA AC 150 (Reference) • • CAT I, CAT II, CAT III requirements
- 5. Runway Lighting System •• Runway Edge Lights – White • • Runway Threshold Lights – Green • • Runway End Lights – Red • • Runway Centreline Lights – White / Red • • Touchdown Zone Lights – White
- 6. Runway Centreline Lights •• White up to last 900 m • • Alternating Red & White from 900 m to 300 m • • Red in last 300 m • • Mandatory for CAT II & CAT III operations
- 7. Approach Lighting System(ALS) • • Provides visual guidance during final approach • • Types: ALSF-1, ALSF-2, CAT I ALS • • Includes centerline, crossbars, sequenced flashers
- 8. Taxiway Lighting System •• Taxiway Edge Lights – Blue • • Taxiway Centreline Lights – Green • • Stop Bar Lights – Red • • Clearance Bar Lights – Yellow • • Runway Guard Lights – Yellow (wig-wag)
- 9. Stop Bar Lights •• Red unidirectional lights • • Installed at runway holding points • • Used during LVP • • Aircraft must not cross when illuminated
- 10. Apron Lighting • •Provides illumination for aircraft parking • • Floodlights mounted on masts • • Ensures safe ground handling operations
- 11. Obstruction Lighting • •Marks obstacles hazardous to aircraft • • Red lights (low/medium intensity) • • High-intensity white lights for tall structures
- 12. Lighting Control andMonitoring • • Controlled from ATC Tower • • Intensity control (Steps 1–5) • • Standby power supply • • Lighting monitoring and alarms
- 13. Low Visibility Procedures(LVP) • • Mandatory use of stop bars • • Centreline lighting required • • Intensity adjusted as per RVR • • Critical for CAT II / CAT III operations
- 14. Importance for AirTraffic Controllers • • Ensure correct lighting configuration • • Prevent runway incursions • • Maintain situational awareness • • Support safe aircraft movement
- 15. Conclusion • Aeronautical GroundLighting is a critical safety system at airports, enabling safe and efficient aircraft operations under all visibility conditions.
