DO-160 Section 19 support for induced-signal susceptibility for interconnected equipment
For equipment suppliers, avionics suppliers, OEMs, this review is used when EMC qualification planning. EE checks induced-signal category and level selection against the wiring environment, test setup and cable routing, performance-during-injection criteria against the approval basis, the configuration baseline, and the available DO-160G reports. The output gives emc engineers and qualification engineers an evidence map, discrepancy register, request list, and closure plan for the records that need applicant, supplier, or authority disposition.
What gets reviewed
- Index induced-signal category and level selection against the wiring environment against the claim it supports.
- Compare test setup and cable routing against the claim it supports.
- Trace performance-during-injection criteria against the claim it supports.
- Challenge tie to the installation's power and signal architecture against the claim it supports.
- Reconcile approval basis against the claim it supports.
- Confirm configuration definition against the claim it supports.
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
- Configuration match: induced-signal category and level selection against the wiring environment fails review if the cited record cannot be tied to the current baseline.
- The review notes that evidence link: test setup and cable routing fails review if the cited record cannot be tied to the current baseline.
- Limit carryover: performance-during-injection criteria fails review if the cited record cannot be tied to the current baseline.
- Source control: tie to the installation's power and signal architecture fails review if the cited record cannot be tied to the current baseline.
- Closure owner: approval basis fails review if the cited record cannot be tied to the current baseline.
Evidence normally required
- Baseline record: induced-signal category and level selection against the wiring environment
- Test file: test setup and cable routing
- Analysis note: performance-during-injection criteria
- Manual source: tie to the installation's power and signal architecture
- Configuration item: approval basis
- Closure evidence: configuration definition
Common discrepancies
- Finding in records: categories chosen without knowing the neighbouring switching loads.
- Installer issue: audio-frequency susceptibility uncovering an interface problem only at aircraft level.
- Buyer concern: test wiring that does not represent the installed harness.
- Program risk: baseline does not match the delivered records.

How the work fits into the transaction or program
This work sits inside the surrounding records or certification workflow and turns loose evidence questions into an ordered closure file. The page-specific framing is whether Section 19 induced-signal categories and levels match the actual wiring routing and neighbouring loads, because Section 19 exposes equipment to power-frequency harmonics, audio-frequency signals, and switching transients coupled through the installation wiring. The review notes that evidence reviewed: the induced-signal category and level selection against the wiring environment, the test setup and cable routing, performance-during-injection criteria, and the tie to the installation's power and signal architecture.. For 160 section induced signal, 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 19 induced signal support scope is intentionally narrow: Review DO-160 Section 19 induced-signal category and level selection against wiring routing.. The 160 Section Induced evidence question is tested against induced-signal category and level selection against the wiring environment and not against a generic checklist copied from another page. The Signal Support Evidence trigger is emc qualification planning, so the review ranks gaps by decision impact instead of document volume. The Review Susceptibility Interconnected searcher pattern is A qualification engineer searches for which DO-160 Section 19 induced-signal category applies to their interconnected equipment.. The Equipment Environmental Qualification evidence trail has to show source location, current status, conflicting entries, and the owner who can close the issue. The Wiring Fit Review 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 evidence map for do-160 section 19 induced signal, 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 whether Section 19 induced-signal categories and levels match the actual wiring routing and neighbouring loads, because Section 19 exposes equipment to power-frequency harmonics, audio-frequency signals, and switching transients coupled through the installation wiring. The review notes that evidence reviewed: the induced-signal category and level selection against the wiring environment, the test setup and cable routing, performance-during-injection criteria, and the tie to the installation's power and signal architecture. The failure pattern includes categories chosen without knowing the neighbouring switching loads, audio-frequency susceptibility uncovering an interface problem only at aircraft level, and test wiring that does not represent the installed harness.

The governing intent remains Review DO-160 Section 19 induced-signal category and level selection against wiring routing.. The operating angle for this page is Decision: whether Section 19 induced-signal categories and levels match the actual wiring routing and neighbouring loads, because Section 19 exposes equipment to power-frequency harmonics, audio-frequency signals, and switching transients coupled through the installation wiring. The review notes that evidence reviewed: the induced-signal category and level selection against the wiring environment, the test setup and cable routing, performance-during-injection criteria, and the tie to the installation's power and signal architecture.

Regulatory limits
EE does not issue approvals, make compliance findings, approve manuals, or determine airworthiness. The review gives the applicant, designee, buyer, or authority-facing team a clear evidence record for their own decisions.
Specific to this review
- whether Section 19 induced-signal categories and levels match the actual wiring routing and neighbouring loads, because Section 19 exposes equipment to power-frequency harmonics, audio-frequency signals, and switching transients coupled through the installation wiring.
- Induced-signal category and level selection against the wiring environment often controls whether later summaries can be trusted.
- Categories chosen without knowing the neighbouring switching loads is treated as a record gap until an owner closes it.
- FAA and EASA evidence should stay distinguishable from commercial claims and installer notes.
- The scope uses the 160 Section Induced Signal question as the control point, so the review stays tied to EMC qualification planning and the buyer decision behind it.
- The evidence starts with Induced-signal category and level selection against the wiring environment and follows Support Evidence Review Susceptibility 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 Interconnected Equipment Environmental Qualification questions in the records or certification lane and sends technical acceptance issues to the authorized people who own them.
- The handoff value comes from Evidence map for DO-160 Section 19 Induced Signal; it gives the next reviewer a precise map instead of another broad request for a better file.

Frequently asked questions
What makes this standards review different from a general file audit?
The scope is tied to 160 section induced signal and to the decision named in the request. A general audit can list weak records; this pass ranks the gaps by whether they block emc 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 induced-signal category and level selection against the wiring environment, 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.
