Introducing Ledger

Every flight checked.
Every release on record.

Ledger keeps one record of your people, aircraft, sites, and rules, and connects it to every mission. You know where you stand before each release. When someone asks about a flight, even a year later, the answer is already there.

See how it works

01

Record

Every release shows what you knew at the time.

Months later, an insurer, a partner, or the FAA asks why a flight went out. Ledger opens it as it stood at release. The pilot, the aircraft, the site, the rules, and the person who signed off.

What you learn afterward is added beside it, with who added it and when. The original stays as it was. When your team makes a careful call, the record shows it.

A release, and the same flight opened eighteen months later, with later notes kept beside the original.

02

Ready

Anything coming due reaches the right person in time.

Ledger keeps your aircraft, people, sites, and rules current from the systems you already run. When something is about to expire, or can no longer be confirmed, the person who owns it is told.

The chief pilot schedules the check. Maintenance replaces the part. By launch, the work is already done, and your pilots can focus on the flight.

Launch is at 06:14 UTC. Days before, each due date has already reached the person who owns it.

03

People

Thousands of flights. Your leaders see the few that need them.

An operation this size rests on a few people. The accountable executive, director of operations, chief pilot, director of maintenance, safety manager, regulatory affairs, and counsel.

Ledger checks every mission against every rule that applies. Clear missions continue, with the record kept. The few that need a person go to that person, with the reason and whether it is a company rule, a regulation, or a safety control.

Four thousand missions and seven people. Three missions need a person, and each arrives with its reason.

04

Rules

Company rule, regulation, or safety. You always know which.

Each kind of rule asks for a different kind of care. A company rule is your own standard. A regulation is the law. A safety control is a call your safety team made. Every flag shows which one it is, and the release stays a named person's decision.

Across flights, you can see what repeats. Which sites, which rules, which parts are getting close, and whether a safety call held. You can see where your own standards came up and where a regulation did.

Three missions need a person. One is a company rule, one is a regulation, and one is a safety control. You can tell them apart at a glance.

05

Safety

When someone speaks up, the whole operation learns.

For example, a confidential report describes hard landings in gusty wind at Site 12. Safety sets a rule, no launches there above 15 knots. It applies to Site 12 immediately, and every mission it covers is checked from then on.

Confidential reports stay with the people trusted to hold them. The safety program still learns from each one. Your people can speak up and trust how it will be handled.

Someone speaks up. Safety decides. The decision becomes a rule, and every mission it covers is checked.

One flight

Follow one flight through Ledger.

The names and numbers here are an example.

  1. 7 days before

    A confidential report describes hard landings in gusty wind at Site 12. Safety sets a rule, no launches there above 15 knots, and it applies right away.

  2. 3 days before

    A pilot's recurrent check comes due, and the chief pilot is told and schedules it. A life-limited part on Aircraft 214 nears its limit, and maintenance is told and replaces it.

  3. 05:31 to 05:54 UTC

    Aircraft 214 gets firmware 4.2. The functional test is flown at 05:52 and recorded at 05:54.

  4. 06:14 UTC

    Mission 48213 is checked against every rule that applies, including the wind rule. Of four thousand missions that day, three need a person. This one is clear, and the person who released it is named.

  5. 06:16 to 06:41 UTC

    Aircraft 214 flies, and its log comes back and is kept exactly as received. The plan stays, and what happened is added beside it.

  6. 09:40 UTC

    A technician corrects the test time from 05:52 to 05:58, and the correction carries a name and a time. The 06:14 release still shows what was known then.

  7. 1 year later

    The wind limit has changed since, and an insurer asks about this flight. The mission opens exactly as it stood that day.

07

Answers

When the FAA or an insurer asks, you have the answer.

A partner, an insurer, or the FAA each gets exactly the flights they asked about, as they stood that day. You review the answer and put your name on it before it goes out.

On May 28, 2027, a Part 135 carrier signs that its safety management system meets Part 5 and that its records can be opened. With Ledger, those are the records your operation already uses every day.

Three people ask three questions. Each one gets the flight they asked about, as it stood that day, with your name on the answer.

Years from now

A record your whole operation can stand behind.

Your team does careful work every day. Ledger keeps that work in one record, so you can show it whenever it matters. When Part 108 arrives, its rules are checked against the same people, aircraft, and sites.
