Sojourn Logbook In development
We log your career,
not just your flights.
Hours, duty, rest, standby, training — the whole working record, for pilots and cabin crew. Every rule read from the authority’s own legislation, versioned and dated.
Ten authorities verified. One tap turns the record into the CV you send.
The problem
A logged hour is not a portable fact
Two pilots fly the same sector. One files with the FAA, one with EASA. The FAA counts night from the end of evening civil twilight; the UK CAA and Hong Kong count it from thirty minutes after sunset; Singapore counts twenty. The same wheels-up to wheels-down produces different night totals — legitimately.
Command time is worse. The FAA lets the sole manipulator log PIC even with an instructor aboard. EASA reserves PIC for the designated commander and puts supervised command in a separate, countersigned PICUS column. There is no honest way to convert one into the other after the fact.
So a logbook that stores “3.2 hours night, 6.4 PIC” has already thrown away the information needed to be correct anywhere else. Most logbooks pick one definition and hope you never move country.
The approach
Store what happened. Compute at export.
Sojourn stores raw facts: block and airborne times in UTC, the route and aerodromes, the sun and twilight timestamps for that position and date, the crew role as flown, and actual IMC, hood, and time-under-IFR as three separate fields.
Night, cross-country and PIC are never stored as numbers. They are computed against the rules of whichever authority you are exporting to, at the moment you export.
File with the FAA on Monday and EASA on Friday from the same record, and both are right.
How the rules are built
We don’t guess. We verify.
Most logbooks hand you a blank template and expect you to copy your limits off a screenshot, or import another pilot’s file. No source, no date, no way to tell whether what you are filing is still current.
Every rule in Sojourn — how an authority defines night, what counts as command time, where cross-country begins — is read from that authority’s own legislation and recorded with the clause it came from. Each rule set is versioned and dated. When a regulation changes, the rule set changes with it and the date moves.

Designed differently
Two jobs. One record.
Most logbooks do one job: prove what you flew. Your duty and rest live somewhere else entirely — usually your operator’s rostering system — and you find out where you stand when somebody else decides to tell you.
Sojourn was built to do both from the same entries. The record that keeps your hours straight for your licence also runs duty, rest and the cumulative limits against the authority you fly under. Log the sector once, and both move — your experience record and your flight-time-limitation position.
That is the whole reason the record stores raw facts rather than tidy totals. An hours record and an FTL clock ask different questions of the same flight, and only the unrounded version can answer both.
Fly for anyone. Don’t see your operator’s rules? Send them — we’ll build the scheme, and it then works for everyone at your airline.
Version one computes your actual position from the record you already keep, with no roster feed required — forward projection comes after. Sojourn shows you where you stand. Figures are indicative — confirm against your Operations Manual. Not legal advice.
For cabin crew
You’re the one who has to say no.
Flight time limitations are not a flight-deck matter. Your airline rosters you and keeps the official record — but the obligation not to begin a duty that exceeds your limits sits with you as well. You are the last check.
And you are asked to make that call with nothing. No running total, no record of your own, because cabin crew have never been given one. A roster tells you what you are doing next. It does not tell you where you stand.
The limits are your own, not a footnote to the flight-deck scheme. Under the GCAA scheme a cabin crew member may be rostered to 210 duty hours in twenty-eight days where a pilot stops at 190, on a rest floor an hour shorter — and on some route mixes to 1,200 flight hours a year against a pilot’s 900. In Singapore it is 100 duty hours in fourteen days against a pilot’s 90. In New Zealand there is no cabin-crew flight-time rule at all.
Higher limits, shorter rest — and the only record of either belongs to the company you would be disputing it with.
We log your career, not just your flights. Sojourn keeps the whole working record — duties, standby, reserve, positioning, training — and turns it into two things cabin crew have not been offered before.
Your experience, as a document. Hours and sectors by aircraft type, the fleets and the routes, the operators you have flown for, ultra-long-range operations, time in charge. One tap, and the career you actually have is on paper. Recruiters have never had anything to read.
Your own track. An independent record of your duty and rest, kept by you, on your device. Not to prove anyone wrong — to prove what you recorded, and when. Without your own record, you depend on whatever the other party brings to the table.
Figures are indicative — confirm against your Operations Manual. Not legal advice.
What comes out
One record. Three documents.
Night, function time, duty and rest are computed from the same canonical record and rendered for whoever has to read them — an authority, a recruiter, or you. These pages are the engines’ actual output, not mock-ups.
Sample documents. Every figure is computed by the Sojourn engines; the pilot and operator are fictional. Sojourn Logbook is in development.
Sojourn Tax
Your logbook already holds part of the answer
If you also fly for a living across borders, the sectors in your logbook help decide your tax residency — part of the picture, not all of it. Sojourn Tax can read them straight from Logbook — on your device, with your permission, and never as a silent write.
Every import lands as a review session you approve, line by line. Licence data never crosses: no command times, no endorsements, no instructor names.
You grant consent, per product
Nothing moves until you say so, and you can revoke it.
Legs transfer on-device
No server sees the data. It never leaves your phone.
You review before anything is written
Tax proposes; you confirm. Your residency record is never changed behind your back.
Pricing at launch

Free exists so you can check our work before you switch. Bring in twenty years from your current app, a spreadsheet, or a photo of a paper book — free, unlimited, and nothing is written until you confirm it. Then watch what happens: your total time reconciles to the hour, and where your night or command totals differ from what you brought, we show you the rule that moved them. That is the whole product, demonstrated on your own record. Exporting it is what a subscription is for.
Starter Pro is free because a career record is worth most when it starts at hour one. Pilots keep it for the whole of training. Cabin crew keep it for a year — long enough to cover initial training and the first months on the line, so the record is already yours by the time you are asked to pay for it.
