Share your fleet's documents

This tutorial walks you through setting up your syndicate’s document library from scratch, then carrying it on your phone. By the end, you’ll have the syndicate agreement and house rules on file, the lead aircraft’s ship’s papers uploaded with expiry dates, and the whole lot cached on your phone so a ramp inspector at an out-and-back to France can see them with the data roaming off. Plan on about fifteen minutes, give or take how long it takes you to find the bank mandate.

You’ll need to be signed in as an admin of a syndicate that has at least one asset. If you’re starting cold, scan Create a syndicate and Add an asset first.

Step 1: Open the document library

Section titled “Step 1: Open the document library”

Open the syndicate and tap Documents on the dashboard. If this is the first time anyone’s touched the library, you’ll see two empty sections: the syndicate section at the top and a section for your asset below it.

The library is the single screen for everything; there is no separate “asset documents” page. Each section has its own + button on the right of the header. That’s the only way to upload. There’s no global add button.

Step 2: Upload the syndicate agreement

Section titled “Step 2: Upload the syndicate agreement”

Tap + on the syndicate section. The upload screen opens with the Owner already set to the syndicate.

Tap Choose file and pick the syndicate agreement PDF from your phone or laptop. PDFs, JPEGs, PNGs, and WebP are all accepted up to 20 MB.

The Title fills in from the file name. Make it something a fellow admin will recognise: Syndicate Agreement v3 Signed 2026 is more useful than agreement_final_v3_signed.pdf. Leave Expiry blank: most syndicate documents don’t expire.

Choose Syndicate agreement from the Type dropdown. The dropdown is filtered to syndicate-level types only: syndicate agreement, house rules, bank mandate, hangar lease, and other (syndicate).

Tap Upload. The library returns; your syndicate agreement is the first row in the syndicate section.

Step 3: Add the house rules and the bank mandate

Section titled “Step 3: Add the house rules and the bank mandate”

Repeat Step 2 twice more. House rules first: pick House rules from the dropdown. Then the bank mandate: Bank mandate.

Your syndicate section now lists three rows: agreement, house rules, mandate. Members will see all three the next time they sync.

The Available offline badge on the section header tells you these three documents are cached on every member’s phone automatically. That’s the rule for syndicate-level documents: tiny in volume, universally useful, so no opt-in.

Step 4: Move on to the aircraft

Section titled “Step 4: Move on to the aircraft”

Scroll down to the asset’s section. Tap + on its header. The upload screen opens with the asset pre-selected as the Owner, so you don’t have to pick it again.

This time the type dropdown shows asset-level types: ARC, insurance, CofA, CofR, radio licence, noise certificate, Mode S check, ELT registration, weight and balance, POH, hangar lease, and other (asset).

Start with the insurance schedule. Pick the file, set the title, and fill in the Expiry date (insurance always renews, so this matters). Look at the insurance certificate to find it. Setting the expiry now is what unlocks the renewal reminders later: Syndik8 will nudge you 30, 7, and 1 day before the expiry, and again if it slips by. (See Document expiry alerts for the full schedule.)

Tap Upload.

Step 5: Keep going with the rest of the ship’s papers

Section titled “Step 5: Keep going with the rest of the ship’s papers”

Repeat for ARC, CofA, CofR, radio licence, noise certificate, and POH. Set expiry dates on the ones that actually expire (ARC and radio licence are annual; insurance is annual; the others are usually indefinite).

Take your time. You only do this once per asset. The next time a document needs renewing you’ll just replace the existing row, not start from scratch (see Replace a document).

By now your asset section is properly populated. The library reads like a maintenance log: title, type, expiry, last updated.

Step 6: Switch the offline cache on (multi-asset syndicates only)

Section titled “Step 6: Switch the offline cache on (multi-asset syndicates only)”

If your syndicate has more than one asset, find the Cache on this device toggle on the asset’s section header. Switch it on. Syndik8 downloads every document in that section into your phone’s cache.

If your syndicate has exactly one asset, you’ll see an Available offline badge instead of the toggle. Single-asset syndicates cache every asset document by default, so there’s nothing to switch. Skip to Step 7.

Web doesn’t have a cache. If you’re following along on a laptop, do this step on your phone afterwards. The library is a synced screen, so your edits from the laptop are already on the device.

Step 7: Verify with a no-signal test

Section titled “Step 7: Verify with a no-signal test”

You don’t have to wait for a real ramp check to test this. Put your phone into Aeroplane mode. Open the syndicate. Tap Documents. Open the ARC.

The PDF renders. There’s no spinner, no “no internet” complaint. The file is on disk and the viewer fetched it from disk.

Turn Aeroplane mode off again.

You’re done

Section titled “You’re done”

Your syndicate’s documents are uploaded, expiries are tracked, and the whole library is on your phone for the next time you fly without a signal. Members of the syndicate will see exactly the same library; what they cache offline is their own choice. And next time the ARC renewal is due, you’ll get a reminder in plenty of time.
