Individually accepted taxiway fixtures are only the starting point. Division 07 commissions the complete taxiway lighting system — edge, centreline, clearance bars, exit lighting and rapid-exit lighting — as one integrated whole, verifying that circuits, cables, fixtures, connectors, current, intensity, switching, control, alarms and photometric performance all operate correctly together.
Philosophy: this division follows Division 06 — Runway Lighting System Commissioning — and applies the same overall approach: System Identification → Circuit Verification → Cable/Connector/Fixture Verification → Energization → Current → Intensity → Switching → Control → Alarm → Photometry → Functional Test → Acceptance. Division 05 answers whether an individual fixture is acceptable; Division 07 answers whether the complete taxiway lighting system operates correctly.
Every taxiway lighting subsystem moves through the same underlying sequence, from system identification through to the integrated acceptance gate.
The taxiway lighting system is evaluated as a complete chain — every link has to hold before the system is accepted. Even if every individual fixture has passed Division 05, the system can still fail Division 07 on any one of these links.
| Link | What It Confirms |
|---|---|
| Accepted Fixtures | Individual edge, centreline, clearance-bar, exit and rapid-exit fixtures carry a valid Division 05 acceptance |
| Healthy Circuit | Primary and secondary circuit continuity and insulation satisfy the applicable procedure |
| Healthy Cables | Cable route, continuity, insulation, termination and joints are sound and traceable end to end |
| Healthy Connectors | Connectors mate, lock, seal and carry current correctly at every transformer and joint |
| Correct Current | CCR output and taxiway circuit current agree at every commanded intensity step |
| Correct Intensity | The intensity command reaches the complete system, not merely the CCR |
| Correct Switching | ON, OFF and intensity selection respond correctly with no unintended operation |
| Correct Control | Local and remote control commands are correctly acknowledged with accurate status feedback |
| Correct Alarms | Fault conditions are detected, indicated, and recover correctly on reset |
| Photometric Compliance | System-level photometric performance satisfies the applicable acceptance criterion |
| Accepted Taxiway Lighting System | All applicable results are recorded and the system is formally accepted |
Two conditions should be established before Division 07 commissioning of any taxiway lighting subsystem begins.
Grouped by commissioning focus, in the order each taxiway lighting subsystem is normally worked through — click any topic to expand its verification checks and acceptance criteria.
Acceptance Criteria: the complete edge-light system is verified end-to-end from CCR to fixture with correct illumination, intensity operation, and control response.
Acceptance Criteria: centreline lighting operates correctly at every applicable intensity setting with no circuit interruption.
Acceptance Criteria: the clearance bar operates as intended under all applicable operating conditions, where installed.
Acceptance Criteria: all applicable exit-light fixtures operate correctly and respond to the designated control commands, where provided.
Acceptance Criteria: the rapid-exit lighting system operates correctly in conjunction with the associated taxiway lighting system, where provided.
Hold Point: circuit insulation acceptance values are taken from the applicable project/manufacturer procedure, never an arbitrary universal figure.
Acceptance Criteria: the cable network is verified continuous, correctly insulated, and correctly traceable from CCR through to fixture.
Division boundary: Division 05 establishes the detailed individual-fixture testing methodology — Division 07 confirms that accepted fixtures function correctly within the complete taxiway lighting system.
Acceptance Criteria: fixtures are confirmed to function correctly within the integrated taxiway lighting system.
Acceptance Criteria: connector assemblies are verified for continuity, contact, mating, locking, sealing, and mechanical integrity.
Hold Point: any abnormal current result at any intensity step is investigated and resolved before proceeding.
Acceptance Criteria: the test demonstrates that the intensity command reaches the complete taxiway lighting system, not merely the CCR.
Acceptance Criteria: switching functions are confirmed correct at every applicable point with no unintended operation.
The complete ALCMS/SCADA/PLC integration remains within the applicable dedicated control-system commissioning scope; Division 07 verifies the taxiway lighting system's response to those control commands.
Acceptance Criteria: the taxiway lighting system responds correctly to all applicable control commands.
Acceptance Criteria: applicable alarms and fault indications are confirmed to detect, indicate, and recover correctly.
The dedicated photometry division treats photometry as a technical activity in its own right, covering equipment verification, calibration, and detailed measurement methodology. Division 07 = taxiway system-level photometric verification.
Hold Point: photometric equipment calibration status is verified valid before any measurement is recorded.
Acceptance Criteria: the complete integrated taxiway lighting system passes the functional test across every subsystem, electrical, control, alarm, and photometric requirement.
Acceptance Criteria (final logic): Accepted Fixtures + Healthy Circuit + Healthy Cables + Healthy Connectors + Correct Current + Correct Intensity + Correct Switching + Correct Control + Correct Alarms + Photometric Compliance = ACCEPTED TAXIWAY LIGHTING SYSTEM. The system-level acceptance gate remains independent of individual fixture acceptance.

A short checklist view and test view of Division 07. Confirm every criterion against the approved specification and the current standard.
A taxiway lighting commissioning checklist follows the division sequence. (1) Confirm fixtures have passed Division 05 and the system is identified against the drawing. (2) Verify taxiway edge, centreline, clearance-bar, exit and rapid-exit lighting for location, type and orientation. (3) Verify circuit identification, cables and connectors. (4) Verify CCR output and circuit current at each applicable intensity step. (5) Verify switching and control, local and remote. (6) Verify alarms where provided. (7) Verify photometric performance where required. (8) Run the system functional test and sign the taxiway acceptance test.
The taxiway lighting commissioning test proves the taxiway lighting works as one system. It checks that edge and centreline lighting give continuous guidance, that clearance bars and exit lighting operate on their own circuits, and that intensity steps and control commands give the expected response. Acceptance closes only when installation compliance, circuit and cable results, control and alarm behaviour and the system functional test are all documented.
Quick answers about Division 07 — Taxiway Lighting System Commissioning in the AGL Testing & Commissioning Manual.
Division 07 of the AGL Testing & Commissioning Manual covers Taxiway Lighting System Commissioning. Individually accepted taxiway fixtures are only the starting point. Division 07 commissions the complete taxiway lighting system — edge, centreline, clearance bars, exit lighting and rapid-exit lighting — as one integrated whole, verifying that circuits, cables, fixtures, connectors, current, intensity, switching, control, alarms and photometric performance all operate correctly together. It contains 17 topics (TC-TWY-001 to TC-TWY-017) organised into 6 groups (A–F), each topic with its own verification checks.
This division follows Division 06 — Runway Lighting System Commissioning — and applies the same overall approach: System Identification → Circuit Verification → Cable/Connector/Fixture Verification → Energization → Current → Intensity → Switching → Control → Alarm → Photometry → Functional Test → Acceptance. Division 05 answers whether an individual fixture is acceptable; Division 07 answers whether the complete taxiway lighting system operates correctly.
Every taxiway lighting subsystem moves through the same underlying sequence, from system identification through to the integrated acceptance gate. Steps: System ID → Circuit Verification → Cable / Connector / Fixture → Energization → Current → Intensity → Switching → Control → Alarm → Photometry → Functional Test → Acceptance. Focus areas: Edge, centreline & clearance-bar lighting; Exit & rapid-exit lighting; Circuit, cable & connector integrity; Current, intensity & switching performance; Control, alarm & photometric compliance.

The taxiway lighting system is evaluated as a complete chain — every link has to hold before the system is accepted. Even if every individual fixture has passed Division 05, the system can still fail Division 07 on any one of these links. Accepted Fixtures: Individual edge, centreline, clearance-bar, exit and rapid-exit fixtures carry a valid Division 05 acceptance; Healthy Circuit: Primary and secondary circuit continuity and insulation satisfy the applicable procedure; Healthy Cables: Cable route, continuity, insulation, termination and joints are sound and traceable end to end; Healthy Connectors: Connectors mate, lock, seal and carry current correctly at every transformer and joint; Correct Current: CCR output and taxiway circuit current agree at every commanded intensity step; Correct Intensity: The intensity command reaches the complete system, not merely the CCR; Correct Switching: ON, OFF and intensity selection respond correctly with no unintended operation; Correct Control: Local and remote control commands are correctly acknowledged with accurate status feedback; Correct Alarms: Fault conditions are detected, indicated, and recover correctly on reset; Photometric Compliance: System-level photometric performance satisfies the applicable acceptance criterion.
Two conditions should be established before Division 07 commissioning of any taxiway lighting subsystem begins. Division Boundaries: Division 05 establishes the detailed individual-fixture testing methodology; Division 07 confirms that accepted fixtures function correctly within the complete taxiway lighting system; Connector identification, continuity, contact, mating, locking and sealing also sit within the broader Cable & Connector Testing division; The complete ALCMS/SCADA/PLC control-system integration remains within the applicable dedicated control-system commissioning scope; Division 07 verifies the taxiway lighting system's response to those control commands; The dedicated photometry division establishes the detailed measurement methodology; Division 07 performs the taxiway system-level photometric verification. System-Level Independence: The system-level acceptance gate must remain independent of individual fixture acceptance; Incorrect circuit loading, cable insulation failure, connector failure, incorrect current or intensity response, switching failure, control-system failure, alarm failure or photometric non-compliance can each fail the system even with fully accepted fixtures; Any abnormal current or intensity result should trigger investigation of fixture, transformer, cable, connector, circuit loading and CCR operation before proceeding; No taxiway lighting subsystem is released to the integrated functional test until every applicable item in this division is closed.
