why this, why now
European aviation is reaching for infrastructure.
The previous-generation tool stack was built to manage operations. GA Flight is built to write them — once, continuously, into a signed ledger that operators can carry.
fragmentation
Three silos per flight
Planning, logbook, and billing live in separate systems. Every sortie gets re-typed. Every audit becomes archaeology.
regulation
EASA retention is rising
ARA.GEN.220 records need to stay verifiable for years. Screenshots and spreadsheets won't hold up — signed ledgers will.
composition
The network wants a substrate
Pilot identity, school directory, maintenance records — they only compose if they share a common signed layer. That layer is what GA Flight builds.
what GA Flight replaces
From fragmented tools to one signed chain.
The same operation, rewritten once on infrastructure instead of stitched across four applications.
previous generation
GA Flight layer
A stack, not a tool.
GA Flight is built in four composable layers. Every operation on L2 is bound to an identity on L1, written to the ledger on L3, and surfaced as actionable signal on L4. You don't pick features — you sit on infrastructure.

Every record, provably yours.
Every signed record in GA Flight can be packed, signed with the organization's Ed25519 key, and handed to a pilot, inspector, or successor school. The pack verifies against the chain — without GA Flight having to be online.
- Logbook entries bound to the flights they came from — instructor signatures preserved.
- Training credits traceable to the signed sortie that issued them — no re-keying, no drift.
- Share tokens with expiry, access counts, clean revocation.
- Self-verifying open pack format — records survive any migration.
Aviation Operations As A Network
Every operator joins a network designed to compound.
GA Flight is built so that the value of being on the platform grows with each operator, pilot, and aircraft on it. The architecture is in place from day one — regardless of network size today.
Identity
A pilot's record travels with them.
A student's logbook, training stage, and signed records travel across organizations. Schools no longer lose pilot continuity at handoff. Pilots no longer rebuild their record from scratch.
Authority
Evidence aggregates beyond a single organization.
Operational records, instructor signatures, and aircraft history aggregate into authority-facing packs (DGAC, EASA national authorities). The chain extends beyond a single organization's perimeter.
Network signal
Discovery grounded in real operational records.
Marketplace, school discovery, and instructor matching are grounded in real operational records — not marketing profiles. Verified flight history, fleet, and training pathways will become the connective tissue as the network grows.
The network exists in architecture today. Its scale will grow as operators join — we describe its design, not its current size.

platform
Four layers, one platform.
GA Flight is built as a composable stack — every layer is observable, every layer is replaceable in principle, no layer claims to be a silver bullet.
L1 — Identity
liveorg · pilot · aircraft · entitlements
Organizations, pilots, aircraft and entitlements modeled as identity objects. Pilots carry their record across schools. Aircraft carry their history across owners. Role and permission are first-class, not afterthoughts.
L2 — Operations
liveplanning · flights · training · logbook · fleet · maintenance · finance · compliance
Planning, flights, training, logbook, fleet, maintenance, finance and compliance — wired on one shared substrate so every operation writes once and propagates across the stack.
L3 — Authority
livehash chain · Ed25519 · evidence packs · share tokens
Ed25519-signed hash chain, typed evidence packs (aircraft, pilot_portable, compliance, training, finance, audit), share tokens with expiry and revocation, offline-verifiable manifests.
L4 — Intelligence
previewOps Twin · priorities · opportunities · evidence pointers
Daily briefings generated from the operational thread, with priorities, opportunities, and delta-since-yesterday — every insight carries an evidence pointer back to the underlying signed record.
Web Console
Operational control for aviation organizations.
The Web Console is the daily command environment for dispatch, flights, training, fleet, compliance, and financial control — for every organization that trains pilots and flies aircraft.

Aviation Network
Three entry points into the GA Flight network.
Operators, pilots, and the public each have a dedicated surface. All grounded in the same operational core.
School Discovery
Flight schools with credible public profiles.
Real training pathways, fleet records, and operational history — not a marketing directory.
Public Utility
Daily METAR and TAF awareness.
Free public surface for pre-flight planning, dispatch preparation, and club display mode.
Marketplace
Jobs and opportunities on aviation records.
Connections grounded in verified flight history and training progression — not generic profiles.
network · bootstrap phase
Honest framing : the network is young.
We are seeding the directory and the pilot-portable identity layer. Until coverage is meaningful, the network's value is primarily the infrastructure it sits on. We say so out loud rather than overclaiming.
Why GA Flight
Credibility earned through operational clarity.
GA Flight is built around the realities of flight training organizations and pilot progression, with product depth where aviation organizations need reliability most.
platform baseline
GA Flight is the infrastructure layer for European general aviation — built for flight schools, aeroclubs, ATOs and flight training organizations. Every operation writes to a signed ledger. Every pilot carries a portable identity. Every record survives the software.
Signed by the organization
Every operational record carries an Ed25519 signature from your organization's key — not a screenshot, not a PDF, a ledger entry.
Portable pilot identity
Pilots carry their signed logbook across schools, aeroclubs and training organizations. Identity is not locked to the vendor.
Offline-verifiable evidence packs
Authority packs verify against the signed chain without GA Flight needing to be online. The proof travels with the record.
Four composable layers
Identity, operations, authority and intelligence sit on the same substrate — observable and replaceable independently, not bundled into one opaque app.
EU-hosted, residency-guaranteed
Data stays in European jurisdictions. No US-to-EU transfers for training records, no extraterritorial exposure on pilot files.
Open pack format
Evidence packs are a documented format — readable beyond GA Flight and beyond today. Regulators can verify them in 2036.
One signed chain, not four silos.
Planning, flights, training, logbook, fleet, maintenance, finance and compliance all write to one thread. No re-keying between systems. No drift between sources.
EU-first finance. France, Germany and Portugal first complete.
Aligned with EASA Part-FCL record-keeping. Structured for DTO and ATO inspections. The finance core is a country-pack architecture — no hardcoded jurisdiction. France, Germany and Portugal are the first complete packs (FEC with lettering + CGI-aligned mentions; DATEV EXTF v7.0 + §14 UStG mentions + USt-IdNr / Steuernummer validation; PT-SAFT schema 1.04_01 with CompanyID = NIF + SNC chart + CIVA mentions). SAF-T baseline remains wired for PL/NO/LU/HU and those per-country packs ship in sequence. Shipped as scoped, not over-promised.
Records that outlive the vendor.
Signed evidence packs verify offline against a portable public key. If GA Flight disappeared tomorrow, your regulatory archive would still be readable and verifiable.
Infrastructure, not a vertical tool.
Four composable layers, typed packs, public verifier, open formats. The platform for European general aviation — not another vertical dashboard.
