US–Europe airline approvals: a practical evidence review
Organise US and European airline approval evidence without confusing FAA OpSpecs, EASA TCO authorisation and economic permissions.
About this article: This information illustrates the potential benefits of Aviation.Bot’s upcoming regulatory library and desktop/web document-review features. It is not compliance guidance, legal advice or a basis for a regulatory, certification or operational decision. Examples demonstrate the workflow; verify applicable official sources and use qualified professional judgement for actual work.
Workflow at a glance

Start with the operator and the proposed operation
A route announcement is a commercial event. The regulatory review behind it contains several different questions: who operates the aircraft, under which air operator certificate, into which territory, with which aircraft and operational privileges? A useful review begins with these facts rather than a broad search for “FAA versus EASA”.
The direction matters. A US airline considering an EU destination and an EU airline considering a US destination do not enter the same foreign-operator process. A group with several operating subsidiaries needs the legal operator identified, even when the passenger-facing brand remains unchanged. Aircraft type, registration, passenger or cargo activity and the intended route belong in the record as separate fields.
That fact pattern gives the reviewer a defensible starting point. It also makes the next research question smaller: which approval or permission addresses this particular part of the operation?

Keep safety authorisation and commercial permission separate
EASA’s TCO guidance describes its safety-authorisation system for third-country commercial air transport operators. Its authorisation and technical specifications define the authorised scope. The page also distinguishes landing operations from overflight and explains that EASA TCO authorisation is no longer the process for operation to the United Kingdom.
For the other direction, the FAA’s foreign air carrier page separates Department of Transportation permission from FAA-issued operations specifications and identifies Parts 91 and 129 as operating standards for foreign operators. Those are different evidence objects; one checkbox labelled “US approval” obscures that distinction.
The lesson is not that every route needs an identical pack. It is that a reviewer should give each approval its own purpose, issuing body, scope and status. Applicable economic permissions, traffic rights, airport requirements and specific operational approvals require their own investigation. This article does not enumerate every permission needed for a route launch.
A synthetic route-change review
Consider a fictional European cargo operator adding a US destination with an aircraft already used elsewhere. This is an editorial example, not an airline case study or a regulatory conclusion.
Its review record could contain:
- Operation facts: legal operator, AOC reference, aircraft identity, cargo activity, destinations and intended start date.
- US safety evidence: current FAA OpSpecs, issuing office, relevant scope and unresolved questions about the proposed operation.
- US economic evidence: DOT permission reference, scope and the person responsible for checking the proposed service against it.
- Supporting procedures: the operator’s controlled manuals, dangerous-goods arrangements where relevant, and operational approvals selected for review.
- Decision record: source editions consulted, changes identified, reviewer, open questions and the approved internal next action.
The evidence artifact is a route-approval register. Each row answers “what does this document prove?” rather than “does the airline have a document with a familiar name?” A row can remain unresolved while the responsible team obtains clarification. An unresolved row is more useful than an AI-generated assurance that two systems are equivalent.
Use comparison to expose missing evidence
Comparison works best at the level of the operational question. Ask which document establishes a privilege, whether the aircraft and activity are within its scope, which procedure supports it, and what would trigger an amendment review. A requirement that looks similar in two jurisdictions can still have a different competent authority, application process or evidence expectation.
The reviewer should retain the actual source passage alongside the summary. Record whether it comes from a regulation, an authority explanation, guidance, an application instruction or the operator’s own approval. A website summary can help identify the right process; it is not a substitute for checking the controlled approval and applicable legal material.
If a source changes, mark which register rows depend on it. This avoids treating every newly published document as a route-launch blocker while allowing the team to identify changes that may affect its authorisation or procedure. Human review still decides the consequence.
Where AI assistance could help
A useful assistant can turn a broad question into a source-led research task: “Identify the authority documents relevant to this operator and operation, separate safety and economic permissions, and list missing facts.” The output should cite passages and distinguish a research suggestion from an applicability decision.
Aviation.Bot’s upcoming regulatory library and desktop/web features are designed to support international airline review like this. The starting libraries cover EASA, FAA, UK CAA, CAAC and Dutch IL&T across multiple document categories. The workflow lets a reviewer bring operator facts, authority publications, operations specifications and selected manuals into one workspace, then draft a cited approval-evidence worklist. Desktop users work with selected local folders and files; browser users upload selected documents to their workspace. Available sources and editions remain visible parts of the review rather than an assumed complete collection.
The practical difference from a typical ChatGPT upload session is the aviation-specific source collection and repeatable document-review workflow: selected regulatory material sits alongside the organisation’s manuals, procedures and evidence, with references the reviewer can reopen. ChatGPT also supports file analysis; Aviation.Bot’s differentiation is how the source set and review task are organised, rather than a claim that general assistants cannot read documents.
Complex tables and forms deserve the same inspection as prose. The workflow is being developed to retain table relationships, headings, footnotes and form context, and to let the reviewer check the original page when extraction is uncertain. Reliable review depends on seeing that structure—not merely receiving a confident summary. Better accuracy, complete table fidelity and time savings require task-specific validation; they are not established by having a curated database.
Begin with one operator, one proposed change and one evidence register. The value is a review another person can follow—not a confident answer detached from the permissions that govern the operation.
