The Aerospace Safety Solution maintains two overlapping compliance views: a Compliance Risksheet for all seven standards (ARP 4754A, ARP 4761, DO-178C, DO-254, DO-160G, MIL-STD-882E, DO-326A), and dedicated DO-178C / DO-254 Objectives PowerSheets that track per-DAL certification objectives.

​
Open the Compliance Matrix

  1. In the project sidebar, click Standards Compliance.
  2. The page loads the FCC Aerospace Standards Compliance Matrix document (COMPLIANCE-001).
  3. Alternatively, navigate to the Risks space and open the document titled FCC Aerospace Standards Compliance Matrix.
The Compliance Matrix is project-wide — it is the only risk document without a system element scope. You will not find it nested under a subsystem or component document.

​
Read the Compliance Risksheet

The Compliance Risksheet covers all non-DO-178C/DO-254 standards. Each row represents one compliance requirement.
ColumnFieldDescription
StandardstandardNameAerospace standard (e.g., ARP 4754A, DO-326A)
SectionsectionNumberSection or paragraph reference
RequirementrequirementTextFull requirement text
StatuscomplianceStatusCompliant, Partial, Non-Compliant, Not Applicable
EvidenceevidenceTypeClassification of supporting evidence
Status color codes: diagram Switch between views using the View selector at the top of the risksheet:
  • Full Matrix — all standards and all requirements
  • Compliance Overview — high-level status summary grouped by standard
  • Evidence Tracking — focuses on evidenceType and evidence references
  • Gaps Only — filters to Non-Compliant and Partial rows; use this during audit preparation
Start every audit review in the Gaps Only view. It isolates the items that need action without scrolling through fully compliant rows.

​
Read the DO-178C and DO-254 Objectives Matrices

For software and hardware certification objectives, open the dedicated PowerSheets:
  1. Navigate to PowerSheets in the sidebar.
  2. Open DO-178C Objectives Compliance Matrix or DO-254 Objectives Compliance Matrix.
Each row is one certification objective. The columns map to assurance levels:
ColumnFieldMeaning
StandardstandardDO-178C or DO-254
Table ReftableReferenceStandard table reference (e.g., Table A-1)
DAL AdalAStatusObjective status at assurance level A
DAL BdalBStatusObjective status at assurance level B
DAL CdalCStatusObjective status at assurance level C
DAL DdalDStatusObjective status at assurance level D
EvidenceevidenceReferenceReference to supporting evidence artifact
DAL status values: ✅ Satisfied (green) · In Progress (orange) · ❌ Not Started (red) · Not Applicable (grey) · Waived (blue) Use the view selector to focus your review:
  • Full Matrix — all objectives across all DAL levels
  • DAL A Only — objectives applicable at assurance level A
  • DAL A & B — combined view for mixed-assurance programs
  • Summary — collapsed view used during Stage of Involvement (SOI) audits
There is no DAL E column in the objectives matrix. DAL E items carry no certification objectives under DO-178C or DO-254 — this is expected behavior, not missing data.

​
Understand Known Data Patterns

The following patterns appear in the reference project and may differ in your deployment.
DO-178C shows 0% classification — This is expected if no design requirements with subType=software have been created yet. All existing design requirements may be typed as electrical or mechanical. Create software-subtype design requirements to populate this metric. DO-326A shows N/A across all metrics — Security threat analysis work items have not been populated. Navigate to the FCC Security Threat Analysis (DO-326A) risksheet to begin entering STRIDE threat assessments.
The Compliance Matrix is a single project-wide document. Do not create per-subsystem compliance documents — the solution expects exactly one compliance specification (document without a systemElementId) per project.

​
Verification

You should now see the Compliance Risksheet with colored status cells across all rows, and the DO-178C or DO-254 PowerSheet displaying objective status across four DAL columns. The Gaps Only view should show only Non-Compliant and Partial rows, and switching DAL views should filter the objectives matrix accordingly.
