Aircraft certification, computed
One connected model for requirements, safety analyses, test evidence and the regulations. Change one thing, and the answer arrives in seconds
Not a pile of disconnected documents
One living model, everything connected
Change one thing and the whole case answers
Evidence always ready to hand over
Building the aircraft is no longer the bottleneck, proving it is
The proof that an aircraft is safe lives in pieces. Requirements in one tool, safety analyses in another, test evidence in spreadsheets. Nothing joins them but a person
More new kinds of aircraft than the rules were written for
One model instead of a filing system
Certification is the price of flight
For novel aircraft, certification now costs more than development itself
SOURCES · INDUSTRY CERTIFICATION COST STUDIES · DO-178C BENCHMARKS
Eight to sixteen tools per programme, and none of them talk, senior engineers keep them consistent by hand, after every design change
Everything on one graph
Requirements, hazards, architecture, tests and evidence are one connected model, graded against the live rule and recomputed on every change
Smarter certification, built to be trusted
It cites the rule or abstains, the trace is the structure not a maintained link, and every gate ladders up to one honest verdict
Every answer is fact, computation, precedent or abstain, and it refuses to invent a number.
Verification truth, reverse orphans and dangling references are found before the authority asks.
2 objectives open · FT-17 running, TC-61 not started
Readiness recomputes live as evidence lands, always answering can we certify yet.
The machine you must prove
Every failure condition, graded against the rule
Proven, not claimed
Watch it catch the mistake as it happens
One failure condition, typed against the live rule. Word it with a cause, or downgrade its severity, and the check fires that moment, cited and computed
A different kind of machine
Tools that draft certification documents with language models now exist. Useful, and not this
The detector shall alarm at 2 per cent
plausible · unverifiedGenerates likely text, fast. A human verifies every line, because the machine cannot
Derives the verdict from your evidence, cited to its source and reproducible bit for bit. Where evidence is absent, it says so
From the first hazard to the sealed case
Six analyses, one linked flow, every verdict graded against the 25.1309 ceiling, catastrophic ≤ 1e-9
- 01FHA
Functional Hazard Assessment
Failure conditions, severities and safety objectives, the source of truth
- 02FMEA
Failure Modes & Effects
Component failure modes derived from the model, with a criticality matrix
- 03PSSA
Preliminary System Safety
Architecture allocated against 25.1309 targets, with DAL and budget checks
- 04FTA
Fault Tree Analysis
Quantitative fault trees, cut sets and single points of failure versus target
- 05CCA
Common Cause Analysis
Common-mode groups and particular risks that verify independence
- 06SSA
System Safety Assessment
Closure, every objective marshalled into one computed verdict
- SEAL
Sealed case
Tamper-evident, anyone can verify
Change one thing, and the answer arrives in seconds
That one question sets the timeline of the programme. Answered from the recorded evidence, every factor named, the rule cited, and undetermined where the evidence is missing.
All the engineering in one place
Programme workspace
Requirements, hazards, analyses and verdicts on one connected graph
ARP4761A safety chain
FHA, FMEA, PSSA, FTA, CCA and SSA as one linked, computed flow
Live regulatory grounding
Answered against the live rule text, cited or refused, never guessed
Deep trace health
Verification truth, orphans, dangling refs and DAL flow-down
Evidence integrity
Tamper-evident baselines anyone can verify, no exported files
The grounded crew
Drafts the next row and gap with its sources attached, or abstains
Retire tools, recover time
Software earns its place two ways, better work, or the same work with less resource, here is the arithmetic
A TEAM OF SIX, TODAY
INDICATIVE FIGURES · WORKED CASE BY CASE WITH EACH PROGRAMME
The depth behind every surface
Every answer carries its source
The engine cites the rule or it abstains, it will not invent a number, and an unsourced fact becomes an honest gap
Reasoned across the entire aircraft
Systems, structures, powertrain and software, each graded against the live rule rather than a generic checklist
A verdict that recomputes itself
Readiness updates the moment evidence lands, computed on every change, never a status someone typed
One evidence base, every authority
A programme certifies at home while validating elsewhere, and every authority wants the case in its own terms
The wave is here
Three forces make a living certification case necessary now, not eventually
A whole new category, still ahead
The certification workload of an entire aircraft category is still in front of the industry
The rules move mid-programme
Special conditions for novel aircraft evolve while the programme runs, a case reconciled by hand goes stale against a rule that changed last month
The scarcest resource is judgement
Experienced certification engineers are too valuable to spend on keeping spreadsheets consistent, the platform returns their hours to engineering
Every discipline on one graph
Systems, structures, powertrain and software, every team designing and verifying on the same living model, so a change in one ripples to every other
