IATA AHM 565 / X565 Compliant
The world's first fully digital platform for airline Weight & Balance data.
One system of record for your AHM 565 Weight & Balance data, with a draft → review → approve → publish workflow behind every change. Publish once, then serve it straight to your DCS over an API or as verified X565 XML.
IATA AHM 565 — built in, not bolted on.
Your data is organised exactly as the standard defines it, validated strictly on import, and re-verified on every export.
Validated on import
Every problem is reported at once, each with its exact place in the file. Incomplete data still imports — into a draft you fix before publishing.
Verified export
Every file Tekna Vault produces is re-verified before it is served: it re-imports losslessly.
No lock-in
Your data leaves in the same standard it arrived in, any time you want it.
Key Highlights
All-in-one IATA AHM compliant W&B data platform.
Centralized Fleet Data
Store, view, and analyze every aircraft's W&B data in one place, structured to the IATA AHM standard. Access it from anywhere.
User Management
Control exactly who can view, edit, and approve — per airline, per role. Nothing changes without the right eyes on it.
Advanced Editing
A dedicated editor mode for drafting changes and entering new data, without ever touching the live record.
Version Control & Audit Trail
Every change is versioned automatically. Browse any past state of your fleet's data, with a full audit trail on each version: who drafted, approved and published it, when, and exactly what changed.
Review Workflow
New data moves from draft to review to approval before it ever goes live — a built-in second pair of eyes on every change.
Secure Sharing
Export and share your data with the systems and service providers that need it — as verified X565 XML, any time. Direct API connectivity to DCS systems.
Nothing goes live without review
Every update to your Weight & Balance data follows the same disciplined path — a built-in, role-based draft → review → publish workflow. Editors draft and submit changes, approvers review and publish them, and the live record is never edited in place.
1Draft
Copy-on-write — the live data is never touched while you work.
2Review
Side-by-side against the current version, with computed field-level diffs.
3Approve
A designated approver in your airline signs off on the change.
4Publish
The new version goes live. The old one is retained, never overwritten.
Every published version is retained — the full history of a document is always one click away.
A closer look
Nothing is ever deleted
Every change produces a new version; the old one is kept. Browse any sheet as it looked at any point in its history, and see which publication changed it, when, and on whose approval.
See exactly what changed
Review a draft against the live version with computed field-level diffs — and compare data within a group or between groups of the same aircraft type. No more eyeballing two spreadsheets side by side.
Standard in, standard out
Import your existing X565 XML — whole file or selected aircraft groups — and your data lands fully structured, as a draft you review before it goes live. Export it back as verified X565 whenever you need it. The standard is the interface, not a migration project.
A spreadsheet is not an auditable system of record
Weight & Balance data feeds every load sheet your airline produces. It should never leave safe hands — yet today most of it travels between departments and vendors as Excel attachments.
Go from this
Unlocked files anyone can edit, in folders with no access control, emailed between departments and vendors.
To this
One structured record per airline, every change drafted, reviewed and approved before it goes live, every past version retained.
In development
Coming next: Tekna Optima
Load-plan optimization built directly on the Weight & Balance data your fleet keeps in Vault. Structured, versioned, approved data is the foundation — Optima is what it makes possible.
Why we built Tekna
We have spent years working in and around airline flight and ground operations. The same thing kept surprising us. Weight & balance data — critical for flight safety — is being managed in unlocked and free-text data formats where anyone could modify published production data, managed in disorganized folder structures with no access controls, and files being emailed around and data transferred manually by copy/paste keyboard punching. This is not an auditable or verifiable process for a safety critical process. This can't be the right or best way to manage this data.
Weight and balance data has very little or no redundancy towards errors. Once published to production — it's live and trusted. If this data is created with errors or transferred incorrectly, there is nothing that will stop it or detect it before becoming a risk for flight safety.
The problem isn't the standard — it's the format and medium. Software engineering solved this problem decades ago with version control and code reviews. We need to do airline weight and balance in the same way. IATA lays the foundation with its recent XML-based X565 standard to structure and transfer weight & balance data in machine readable format. Tekna Vault is the framework to store, create, revise, and manage this data, and to share it with those who need it in a secure manner.

Frequently asked questions
Is Tekna Vault compliant with IATA AHM 565?
Yes. Vault is built to be fully compliant with the latest IATA AHM standard from the ground up. It is the platform for managing that data in a smart way, and it validates your data against the standard for you. Import your existing data and Vault checks it, so only validated, AHM-compliant data is exported to production.
Does Tekna Vault fit our existing AHM 565 process?
Yes. Vault speaks the same IATA AHM standard you already use, and your data is structured to be compliant with it — we give you the best tools to keep it that way. Import your data into Vault, validate it, and correct any errors found. Only validated data is exported, in the IATA AHM standard.
Can we get all of our data out?
Any time. Vault exports your published data as X565 XML, and every export is verified before it is served: the generated file is re-run through our own strict importer to prove it re-imports losslessly. Your data leaves in the same standard it arrived in.
Can Vault connect to our other systems?
Vault exports your data as IATA AHM 565 / X565 XML. We can also set up API data connections to other software, such as DCS and EFB systems.
Where is our data hosted?
On AWS cloud infrastructure. Each airline's data is isolated in its own tenant, access is invite-only, and roles are managed per carrier by your own admins.
Who can change our data?
Nobody edits live data directly. Editors work in drafts; a designated approver in your airline reviews the diffs and approves before anything is published. Every change is attributed, and every previous version is retained.
Does Tekna compute load sheets?
No. Vault is the system of record for the semi-permanent W&B data your load control systems consume — it doesn't replace them. Load-plan optimization is the territory of Tekna Optima, a second product currently in development.
