DO-160 Section 17 support for voltage-spike category selection for power inputs
For equipment suppliers, avionics suppliers, OEMs, this review is used when Power qualification planning. EE checks voltage-spike category selection against the power bus, applied spike waveform and count, damage-vs-upset performance 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
- Challenge voltage-spike category selection against the power bus against the claim it supports.
- Reconcile applied spike waveform and count against the claim it supports.
- Confirm damage-vs-upset performance criteria against the claim it supports.
- Index any protection-device substantiation against the claim it supports.
- Compare approval basis against the claim it supports.
- Trace 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
- Source control: voltage-spike category selection against the power bus fails review if the cited record cannot be tied to the current baseline.
- Closure owner: applied spike waveform and count fails review if the cited record cannot be tied to the current baseline.
- Configuration match: damage-vs-upset performance criteria fails review if the cited record cannot be tied to the current baseline.
- The review notes that evidence link: any protection-device substantiation fails review if the cited record cannot be tied to the current baseline.
- Limit carryover: approval basis fails review if the cited record cannot be tied to the current baseline.
Evidence normally required
- Manual source: voltage-spike category selection against the power bus
- Configuration item: applied spike waveform and count
- Closure evidence: damage-vs-upset performance criteria
- Baseline record: any protection-device substantiation
- Test file: approval basis
- Analysis note: configuration definition
Common discrepancies
- Program risk: a category chosen for one bus type applied to another.
- Authority question: protection devices that clamp on the bench but degrade in service.
- Finding in records: spikes tested at input but not accounting for internal power-supply behaviour. Complements.
- Installer issue: does not duplicate.
How the work runs
Frame 160 Section
Confirm the exact event, affected file set, buyer role, and decision standard before any voltage-spike category selection against the power bus is treated as sufficient.
Trace Spike Support
Walk the named evidence from index entry to source artifact and mark where the trail supports, conflicts with, or fails to answer the page-specific question.
Sort Review Category
Group exceptions by closure route: document retrieval, data correction, engineering disposition, authority response, or contractual decision.
Package Power Inputs
Deliver the exception list, evidence map, and owner sequence in a form that can move directly into remediation, submittal cleanup, or transaction negotiation.
What the buyer receives
- The review notes that evidence map for DO-160 Section 17 Voltage Spike
- Discrepancy register for DO-160 Section 17 Voltage Spike
- Applicability and approval basis summary
- Source record request list
Who uses the output
- EMC engineers use the map to brief the decision.
- qualification engineers use the register to assign closure.
- power engineers use the request list to collect source records.
How the work fits into the transaction or program
Which Section 17 voltage-spike category the equipment power input must survive, because it depends on the bus type and the transient environment the installation actually presents, and it sits alongside but separate from the Section 16 power-input page. The evidence set centers on the voltage-spike category selection against the power bus, the applied spike waveform and count, damage-vs-upset performance criteria, and any protection-device substantiation. The likely weak points are a category chosen for one bus type applied to another, protection devices that clamp on the bench but degrade in service, and spikes tested at input but not accounting for internal power-supply behaviour; Complements, does not duplicate, the round-1 Section 16 power-input page. The output gives the EMC engineer a cleanup register for DO-160 Section 17 support for voltage-spike category selection for power inputs before power qualification planning.

Regulatory limits
EE does not grant certification credit, approve data, or sign return-to-service records. The package documents what was checked and what remains open for the responsible certification parties.
Specific to this review
- which Section 17 voltage-spike category the equipment power input must survive, because it depends on the bus type and the transient environment the installation actually presents, and it sits alongside but separate from the Section 16 power-input page.
- Voltage-spike category selection against the power bus often controls whether later summaries can be trusted.
- A category chosen for one bus type applied to another 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 Voltage Spike question as the control point, so the review stays tied to Power qualification planning and the buyer decision behind it.
- The evidence starts with Voltage-spike category selection against the power bus and follows Support Evidence Review Category 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 Selection Power Inputs Environmental 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 17 Voltage Spike; 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 voltage spike and to the decision named in the request. A general audit can list weak records; this pass ranks the gaps by whether they block power 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 voltage-spike category selection against the power bus, 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.
