Division 20 verifies that the complete installed AGL system achieves the required operational, electrical, photometric, control, reliability and availability performance under actual site conditions and in accordance with the approved project specifications and acceptance criteria. It is the performance gate that sits after commissioning, functional testing, photometry and system integration — it does not repeat those procedures, it takes their evidence and renders the final engineering judgement.
Philosophy: the fundamental question Division 20 answers is — does the completed AGL system not only operate, but actually deliver the required performance consistently and reliably? Every applicable parameter is carried through the same chain: Specified Performance → Measured Performance → Acceptance Decision.
Every performance area — from overall system operation down to a single sign — is carried through the same evaluation chain before it contributes to the final acceptance decision.
Division 20 takes the evidence generated by Divisions 02–19, adds the required performance measurements, and makes the final engineering judgement — it should not simply repeat previous test procedures.
| Division | Main Purpose |
|---|---|
| 16 — Photometric Testing | Measure the optical characteristics of the installed lighting |
| 17 — FAT | Verify equipment before site installation/dispatch |
| 18 — SAT | Verify the installed system meets site acceptance requirements |
| 19 — System Integration Testing | Verify that different systems communicate and work together correctly |
| 20 — Performance Acceptance Testing | Verify that the completed system actually achieves the required overall performance |
Two conditions should be established before performance acceptance testing of any AGL system begins.
Grouped by performance focus, working outward from overall system performance through each lighting subsystem, electrical/control performance, photometry, availability and emergency operation, to the final specification compliance and report — click any topic to expand its verification checks and acceptance criteria.
Acceptance Criteria: the complete AGL system, evaluated as an integrated operational system, achieves the required performance across every applicable parameter with no critical deficiency.
Acceptance Criteria: the installed runway lighting system's measured performance matches the runway design requirement across every applicable subsystem.
Acceptance Criteria: operational availability, lighting response, uniformity where applicable, and correct circuit and control operation are confirmed across the installed taxiway lighting system.
Hold Point: the assessment considers the complete installed approach-light system, not only individual fixtures.
Acceptance Criteria: the required PAPI/APAPI performance matches the measured site performance across alignment, beam, colour, and availability.
Acceptance Criteria: the sign remains operational, the correct message is displayed, illumination meets the specified requirement, and control/monitoring operate correctly.
Hold Point: the exact CCR performance acceptance values must be taken from the CCR specification and applicable project documentation, not assumed.
Acceptance Criteria: the entire circuit performs as an integrated electrical path, end to end, under the applicable operating condition.
Acceptance Criteria: the complete command-to-feedback chain performs correctly and within the required response time for every applicable control path.
Acceptance Criteria: every applicable electrical parameter operates within its correct range and responds correctly under expected and abnormal operating conditions.
Note: Division 16 establishes the photometric testing methodology and measurement results; Division 20 evaluates whether those results demonstrate acceptable system performance — photometric performance is treated as a performance acceptance parameter, not merely a measurement exercise.
Hold Point: the acceptance criterion for availability must come from the approved project requirement/specification where one is defined.
Acceptance Criteria: the AGL system correctly performs the complete emergency sequence and recovers to normal operation as specified.
Hold Point: the final acceptance decision is based on objective measured evidence — this is the final technical comparison before certification.
Acceptance Criteria: a single consolidated performance record with a formal certification statement is produced — this is the principal technical evidence supporting final AGL system performance acceptance.
Division 20 runs as a single continuous sequence, carrying every performance area through to the final acceptance decision and consolidated report.

Quick answers about Division 20 — Performance Acceptance Testing in the AGL Testing & Commissioning Manual.
Division 20 of the AGL Testing & Commissioning Manual covers Performance Acceptance Testing. Division 20 verifies that the complete installed AGL system achieves the required operational, electrical, photometric, control, reliability and availability performance under actual site conditions and in accordance with the approved project specifications and acceptance criteria. It is the performance gate that sits after commissioning, functional testing, photometry and system integration — it does not repeat those procedures, it takes their evidence and renders the final engineering judgement. It contains 15 topics (TC-PAT-001 to TC-PAT-015) organised into 6 groups (A–F), each topic with its own verification checks.
The fundamental question Division 20 answers is — does the completed AGL system not only operate, but actually deliver the required performance consistently and reliably? Every applicable parameter is carried through the same chain: Specified Performance → Measured Performance → Acceptance Decision.
Every performance area — from overall system operation down to a single sign — is carried through the same evaluation chain before it contributes to the final acceptance decision. Steps: Specified Performance → Measured Performance → Deviation Assessed → Acceptance Decision → Performance Acceptance Report. Focus areas: Lighting system performance; Electrical & circuit performance; Control-system performance; Photometric performance; Availability & emergency performance.
Division 20 has 15 topics in 6 groups. A — Overall System Performance: Overall System Performance Verification. B — Lighting Subsystem Performance: Runway Lighting Performance, Taxiway Lighting Performance, Approach-Lighting Performance, PAPI Performance, Sign Performance. C — Electrical & Control Performance: CCR Performance, Circuit Performance, Control-System Performance, Electrical Performance. D — Photometric Performance: Photometric Performance. E — Availability & Emergency Performance: System Availability Verification, Emergency-Operation Performance. F — Compliance & Closeout: Performance Against Project Specification, Performance Acceptance Report.
Division 20 takes the evidence generated by Divisions 02–19, adds the required performance measurements, and makes the final engineering judgement — it should not simply repeat previous test procedures. 16 — Photometric Testing: Measure the optical characteristics of the installed lighting; 17 — FAT: Verify equipment before site installation/dispatch; 18 — SAT: Verify the installed system meets site acceptance requirements; 19 — System Integration Testing: Verify that different systems communicate and work together correctly; 20 — Performance Acceptance Testing: Verify that the completed system actually achieves the required overall performance.
Two conditions should be established before performance acceptance testing of any AGL system begins. Acceptance Criteria Are Project-Specific: Required performance values come from the contract specification, approved technical specification and approved drawings — never an assumed universal figure; Availability requirements must come from the approved project requirement/specification where one is defined; Photometric acceptance criteria are the applicable criteria referenced by the project, not a generic benchmark; CCR, circuit and electrical performance values are taken from the CCR specification and applicable project documentation.
Division boundary: Division 16 establishes the photometric testing methodology and measurement results; Division 20 evaluates whether those results demonstrate acceptable system performance; Divisions 02–19 generate the underlying commissioning, functional, photometric and integration evidence that Division 20 builds on; Division 20 is treated as the performance gate after commissioning, functional testing, photometry and system integration; No performance area is accepted until measured evidence is compared against the applicable specified requirement.
Division 20 runs as a single continuous sequence, carrying every performance area through to the final acceptance decision and consolidated report. (1) Overall System Performance — Verify the complete AGL system as an integrated operational system; (2) Lighting Subsystem Performance — Verify runway, taxiway, approach, PAPI and sign performance; (3) CCR & Circuit Performance — Verify CCR output/regulation and end-to-end circuit performance; (4) Control-System Performance — Verify the command-to-feedback chain across local, remote and ALCMS control; (5) Photometric Performance — Evaluate photometric results as a performance acceptance parameter; (6) Electrical Performance — Verify electrical parameters, stability and protection operation; (7) System Availability — Assess availability against the approved project requirement; (8) Emergency Operation — Test emergency response and recovery to normal operation; (9) Performance vs Specification — Compare every parameter against the contract and technical specification; (10) Acceptance Decision — Assign PASS, conditional, retest, or fail based on objective evidence; (11) Performance Acceptance Report — Issue the consolidated report and certification statement.
Performance acceptance testing confirms the system meets its design and regulatory performance criteria, not just that it switches on.
Build the technical knowledge to understand performance benchmarks, acceptance criteria, and how to distinguish a system that functions from one that actually meets specification.
