DO-160G review
DO-160 Section 21 emissions support for equipment suppliers
This page is for equipment suppliers, avionics suppliers, OEMs when Emission scan failure or installation zone change puts do-160 section 21 emissions support on the critical path. EE checks radiated emissions scan, conducted emissions scan, installation zone rationale against the approval basis, configuration baseline, effectivity, revision status, and source records named in the brief. The buyer receives a discrepancy register, evidence map, and closure request list for the next review gate. The work tests records and certification-data traceability only; it does not replace authority, delegate, approval-holder, or authorized-person decisions.
When this review is needed
- Use this review when Emission scan failure or installation zone change starts driving schedule or commercial exposure.
- An avionics engineer with an interference concern or a failed scan searching for how Section 21 categories map to installation locations.
- The highest-risk breakpoint is: category M equipment placed where category H limits apply near a GPS antenna, marginal peaks explained away without an installation-level interference assessment, and scans run on a configuration missing the cables and loads that dominate real emissions.
The problem
At this gate, which Section 21 emission category the installation location demands, driven by proximity to antennas and sensitive receivers rather than by habit. The file set covers category selection against installation zone and aircraft receiver frequencies, conducted and radiated emission scans with limit-line margins, notching around communication and navigation bands, and the disposition of over-limit peaks. Known breakpoints include category M equipment placed where category H limits apply near a GPS antenna, marginal peaks explained away without an installation-level interference assessment, and scans run on a configuration missing the cables and loads that dominate real emissions.
What gets reviewed
- Review the buyer decision in the brief: Select and defend Section 21 emission categories and review emission scan evidence for the actual installation zone.
- Trace radiated emissions scan to source date, revision, owner, and current configuration.
- Match effectivity for conducted emissions scan to the serial range, article version, aircraft, or fleet in scope.
- At this gate, which Section 21 emission category the installation location demands, driven by proximity to antennas and sensitive receivers rather than by habit.
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
- Source status: radiated emissions scan must be current enough for the cited approval basis or records event.
- Range check: conducted emissions scan is mapped to the affected aircraft, article, model, or fleet segment.
- Package consistency: certificate, matrix, instruction, report, and release references are checked as a set.
- Escalation rule: missing rationale is logged as a finding rather than carried as silent credit.
Evidence normally required
- Source record set for radiated emissions scan
- Program file covering conducted emissions scan
- Configuration baseline with approval basis and revision index
- Open issue log tied to installation zone rationale
Common discrepancies
- The file set covers category selection against installation zone and aircraft receiver frequencies, conducted and radiated emission scans with limit-line margins,.
- Known breakpoints include category M equipment placed where category H limits apply near a GPS antenna, marginal peaks explained away without an installation-level interference.
- Revision mismatch leaves installation zone rationale separated from the certificate, matrix, instruction, or delivered baseline.
- Storage completeness is higher than decision readiness because the file lacks a clear disposition for this buying stage.

How the work fits into the transaction or program
An avionics engineer with an interference concern or a failed scan searching for how Section 21 categories map to installation locations. The review packages the evidence before that searcher's next gate, so records, engineering, and certification staff can work from the same exception list. The page-specific framing is which Section 21 emission category the installation location demands, driven by proximity to antennas and sensitive receivers rather than by habit. Evidence reviewed: category selection against installation zone and aircraft receiver frequencies, conducted and radiated emission scans with limit-line margins, notching around communication and navigation bands, and the disposition of over-limit peaks. Failure modes include category M equipment placed where category H limits apply near a GPS antenna, marginal. For 160 section emissions support, 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 do 160 section 21 rf emissions support scope is intentionally narrow: Select and defend Section 21 emission categories and review emission scan evidence for the actual installation zone.. The 160 Section Emissions evidence question is tested against radiated emissions scan and not against a generic checklist copied from another page. The Support Equipment Suppliers trigger is emission scan failure or installation zone change, so the review ranks gaps by decision impact instead of document volume. The 160g Review Categories searcher pattern is An avionics engineer with an interference concern or a failed scan searching for how Section 21 categories map to installation locations.. The Antennas Next Door evidence trail has to show source location, current status, conflicting entries, and the owner who can close the issue. The Emission Zone Fit exception logic separates missing artifacts from mismatched data because those findings move through different closure routes. The Closure Trace Baseline handoff is written for emc engineer, with unresolved items preserved as decisions rather than softened into narrative prose. The deliverable stays anchored on do-160 section 21 emissions support discrepancy 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 which Section 21 emission category the installation location demands, driven by proximity to antennas and sensitive receivers rather than by habit. Evidence reviewed: category selection against installation zone and aircraft receiver frequencies, conducted and radiated emission scans with limit-line margins, notching around communication and navigation bands, and the disposition of over-limit peaks. The failure pattern includes category M equipment placed where category H limits apply near a GPS antenna, marginal peaks explained away without an installation-level interference assessment, and scans run on a configuration missing the cables and loads that dominate real emissions.

Regulatory limits
For do-160 section 21 emissions support, EE reviews radiated emissions scan, conducted emissions scan, installation zone rationale for completeness, consistency, and traceability. The work does not issue approvals, approve data, grant relief, validate STCs, accept release certificates, or make airworthiness determinations. Final decisions remain with the responsible authority, delegate, approval holder, operator, or authorized person.
Specific to this review
- At this gate, which Section 21 emission category the installation location demands, driven by proximity to antennas and sensitive receivers rather than by.
- The file set covers category selection against installation zone and aircraft receiver frequencies, conducted and radiated emission scans with limit-line.
- Known breakpoints include category M equipment placed where category H limits apply near a GPS antenna, marginal peaks explained away without an installation-level.
- The scope uses the 160 Section Emissions Support question as the control point, so the review stays tied to Emission scan failure or installation zone change and the buyer decision behind it.
- The evidence starts with radiated emissions scan and follows Equipment Suppliers 160g Review 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 EMC 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 Categories Antennas Next Door questions in the records or certification lane and sends technical acceptance issues to the authorized people who own them.
- The handoff value comes from DO-160 Section 21 emissions support discrepancy register; it gives the next reviewer a precise map instead of another broad request for a better file.
- The source discipline is stricter on this page than on a general audit because the claim being tested is Select and defend Section 21 emission categories and review emission scan evidence for the actual installation zone..

Frequently asked questions
What makes this standards review different from a general file audit?
The scope is tied to 160 section emissions support and to the decision named in the request. A general audit can list weak records; this pass ranks the gaps by whether they block emission scan failure or installation zone change or can be closed later without changing the decision.
What evidence has to be available before this work starts?
The starting point is radiated emissions scan, 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 emc engineer a closure path. Acceptance remains with the buyer, operator, authority, delegated engineer, or authorized person responsible for the underlying airworthiness or certification decision.
