For BVLOS waiver holders, compliance officers, chief pilots, and accountable executives.
Ledger checks aircraft, people, area, route, and risk before release, then preserves the evidence afterward. Use it under today's authority while the Part 108 readiness record builds underneath.

This is not a logbook you fill in afterward. It's the surface your team uses during the operation, before wheels-up.
What's installed, accepted, current, and airworthy for this mission. Frozen as a snapshot, not a mutable present-state guess.
Who's assigned, trained, current, authorized, and rested, including operational roles a permit, certificate, or BVLOS authorization requires.
Where the operation is approved to occur, the volume it's filed against, and the path it intends to fly.
Which hazards, incidents, governing procedures, and open blockers bear on this release.
What proof will exist once the flight is done, and exactly which records it traces back to.
How it works
One loop. It runs every mission, and it runs the same way every time.
Missions, configuration snapshots, serialized components, operator credentials, checklists, and flight logs, connected in one system. Historical truth, preserved at mission time.
Deterministic checks against Part 107 or Part 135 workflows today, with Part 108 readiness checks running alongside in shadow mode.
Ledger turns the five readiness areas into a release decision before the aircraft flies. Where it says no, findings show what's exposed and what it takes to close it.
Hashed, human-attested evidence packs you can hand to a regulator, insurer, partner, or customer's legal team.
Ledger's findings cite the actual regulation or internal control. Run the same check against the same records and you get the same answer, every time. A release decision you can explain to a regulator has to be reproducible, so there is no AI anywhere in the evaluation loop.
Shadow mode
Part 108 readiness checks run alongside your live Part 107 or Part 135 operations. Every check runs, every finding opens, nothing blocks unless you choose to enforce it. When the rule is final you move from shadow to enforced. You're not starting from zero. You're ratifying a record you've been building all along.
