Aircraft lighting equipment evidence review for DO-160G
This review is for equipment suppliers, OEMs, MROs responsible for aircraft lighting equipment. It is triggered by lighting qualification planning. EE checks photometric intensity, angular-coverage test data against the required light distribution, lightning direct-effects for exterior positions, plus the governing plan or application, against DO-160G. Discrepancies include missing source records, mismatched configuration, unsupported assumptions, or photometrics met on axis but failing at the coverage-angle limits. Output includes Aircraft lighting equipment gap register, Means of compliance map, Test and analysis request list.
When this review is needed
- A new article, software load, or installation is moving into certification review.
- Quality control needs a repeatable list of ready and open records.
- Internal teams need a supplier request list tied to evidence gaps.
- The buyer wants a defensible package before committing the claim.
The problem
Certification risk sits in the gap between the claimed basis and the records in the folder. With aircraft lighting equipment, photometrics met on axis but failing at the coverage-angle limits can stay hidden until the exact source record is requested.
What gets reviewed
- Review photometric intensity against the configuration, installation, or claim under review.
- Compare angular-coverage test data against the required light distribution against the configuration, installation, or claim under review.
- Trace lightning direct-effects for exterior positions against the configuration, installation, or claim under review.
- Challenge eMI/power-quality against the configuration, installation, or claim under review.
- Reconcile dO-160G environmental for the driver electronics against the configuration, installation, or claim under review.
- Confirm emergency-light battery/duration data. against the configuration, installation, or claim under review.
Scope this review
Tell us the asset, the event, and the evidence in scope, and we will outline a focused first engagement.
Identify what is missing against the means of compliance.
What gets validated
- Pass check: photometric intensity must match the released configuration and the claimed means of compliance.
- Configuration check: angular-coverage test data against the required light distribution must match the released configuration and the claimed means of compliance.
- Trace check: lightning direct-effects for exterior positions must match the released configuration and the claimed means of compliance.
- Rationale check: eMI/power-quality must match the released configuration and the claimed means of compliance.
- Closure check: dO-160G environmental for the driver electronics must match the released configuration and the claimed means of compliance.
Evidence normally required
- Controlled photometric intensity
- Released angular-coverage test data against the required light distribution
- Signed lightning direct-effects for exterior positions
- Current eMI/power-quality
- Archived dO-160G environmental for the driver electronics
- Supplier emergency-light battery/duration data.
Common discrepancies
- Gap: photometrics met on axis but failing at the coverage-angle limits.
- Mismatch: lED driver EMI upsetting nearby avionics.
- Unsupported claim: emergency-light duration short of the required evacuation time.
What is at stake
A weak package can convert a planned review into a long question log. If LED driver EMI upsetting nearby avionics, the program may need new evidence before the claim can proceed.

How the work fits into the transaction or program
Programs use the output to align engineering, quality, and certification before the package leaves internal control. The page-specific framing is what aircraft lighting (position/anti-collision exterior lights, LED landing/taxi lights, emergency and cabin lighting) must substantiate, a category no page covers, because the evidence differs by function: exterior nav/anti-collision lights turn on photometric intensity/coverage plus lightning direct-effects on the wingtip, while LED conversions add EMI and power-quality behaviour and emergency lighting adds battery/duration. Evidence reviewed: photometric intensity and angular-coverage test data. For exterior interior lighting tso, the practical output is a defensible record of what was checked, what did not match, who owns the fix, and which issue remains outside the review boundary. The exterior interior lighting tso evidence scope is intentionally narrow: Explain the photometric, EMI, and lightning evidence aircraft lighting needs for certification.. The Exterior Interior Lighting evidence question is tested against photometric intensity and not against a generic checklist copied from another page. The Tso Evidence Aircraft trigger is lighting qualification planning, so the review ranks gaps by decision impact instead of document volume. The Certification Equipment Review searcher pattern is A lighting supplier searches for aircraft position/anti-collision or LED lighting certification requirements when scoping a product or conversion.. The 160g Product Photometrics evidence trail has to show source location, current status, conflicting entries, and the owner who can close the issue. The Emi Lightning Lights exception logic separates missing artifacts from mismatched data because those findings move through different closure routes. The Photometric Trace Baseline handoff is written for certification engineer, with unresolved items preserved as decisions rather than softened into narrative prose. The deliverable stays anchored on aircraft lighting equipment gap register, which makes the next reviewer able to reperform the path without rebuilding the file. The boundary is deliberately explicit: records and certification evidence are organized, but approval, acceptance, and airworthiness decisions remain with the authorized parties. The brief-specific angle is what aircraft lighting (position/anti-collision exterior lights, LED landing/taxi lights, emergency and cabin lighting) must substantiate, a category no page covers, because the evidence differs by function: exterior nav/anti-collision lights turn on photometric intensity/coverage plus lightning direct-effects on the wingtip, while LED conversions add EMI and power-quality behaviour and emergency lighting adds battery/duration. Evidence reviewed: photometric intensity and angular-coverage test data against the required light distribution, lightning direct-effects for exterior positions, EMI/power-quality and DO-160G environmental for the driver electronics, and emergency-light battery/duration data. The failure pattern includes photometrics met on axis but failing at the coverage-angle limits, LED driver EMI upsetting nearby avionics, and emergency-light duration short of the required evacuation time.

Regulatory limits
The output supports applicant decision making and authority discussions. It does not replace required approvals, designee findings, conformity activity, or airworthiness determinations.
What this review does not cover
- Final certification decision
- Airworthiness determination
- Hardware or software redesign
- Production quality release
Specific to this review
- Configuration identity matters because evidence from another baseline may prove a different article, load, or installation.
- A useful trail names the source record, revision, owner, and closure decision for each claim.
- The exception list separates document-control cleanup from gaps that need engineering substantiation.
- The finding pattern for this page is specific: photometrics met on axis but failing at the coverage-angle limits changes the strength of the certification argument.
- The scope uses the Exterior Interior Lighting TSO question as the control point, so the review stays tied to Lighting qualification planning and the buyer decision behind it.
- The evidence starts with Photometric intensity and follows Evidence Aircraft Certification Equipment references until every exception has a source location and a reason code.
- The finding logic separates missing paperwork, conflicting status, stale revision data, and unsupported disposition because each class closes through a different owner.
- The timing matters for Certification engineer: the output is useful only if the unresolved items are visible before acceptance, submittal, handback, or negotiation pressure fixes the sequence.
- The boundary control keeps Review 160g Product Photometrics questions in the records or certification lane and sends technical acceptance issues to the authorized people who own them.
- The handoff value comes from Aircraft lighting equipment gap register; it gives the next reviewer a precise map instead of another broad request for a better file.

Frequently asked questions
What makes this product-types review different from a general file audit?
The scope is tied to exterior interior lighting tso and to the decision named in the request. A general audit can list weak records; this pass ranks the gaps by whether they block lighting qualification planning or can be closed later without changing the decision.
What evidence has to be available before this work starts?
The starting point is photometric intensity, the current status source, and any index or matrix that tells reviewers where the supporting artifact should live. Missing inputs are logged as findings rather than filled with assumptions.
Who decides whether an open item is acceptable?
The review explains what the evidence supports and gives certification engineer a closure path. Acceptance remains with the buyer, operator, authority, delegated engineer, or authorized person responsible for the underlying airworthiness or certification decision.
