The Why's and How's

These are the questions pilots send us most often, most asked first. Use search at the top to find anything else.

How do I import my previous logbook?

Open the Logbook tab, tap the ☰ menu at the top right and choose Import hours. On the web, open Import in the side menu.

Search for your logbook app or your airline, follow the export steps shown for it and upload your file. You get an email when the import is done. Importing from another logbook app is FREE. Importing from an airline crew system or the Wader spreadsheet template is part of PRO.

→ See Importing Your Previous Logbooks.

My airline or logbook app is not in the list

Search for it in the source list anyway: if we cannot import it yet, you can request it from there and our team checks what your system can export. In the meantime, you can copy your flights into the Wader spreadsheet template (PRO) and import that file.

→ See Standard Spreadsheet.

How do I add the hours from my old or paper logbook?

If you only need your earlier totals, not every flight, use Previous Experience: open the Logbook tab’s ☰ menu and choose Previous Experience. Enter your total hours by aircraft type and they count in your Dashboard and your PDF exports straight away. To bring in every flight, type them into the Wader spreadsheet template (PRO) and import it.

→ See Adding Previous Experience.

What happens if I import the same flights again?

Nothing is duplicated: a flight already in your logbook at the same block times is updated from the new file. What you added yourself, such as crew names, remarks and approaches, is kept, but times and functions come from the file, even when a column is empty. If the times in your first import were shifted, delete those flights before importing the corrected file.

→ See Fixing or Updating an Import.


My flights or hours have disappeared

Your flights are kept in the cloud, so they are almost never lost. The usual causes, most likely first: you are signed in to another account, the device has not synced yet, or a search or filter is still on.

→ Work through Finding Missing Flights.

My flights are split between two accounts

Contact us from More › Support Hub and ask for an account merge. Tell us the emails you used and which account you want to keep. Afterwards, sign out and in on every device, and tap Forgot password once if you use email and password.

→ See Duplicate accounts.

My data looks different on another device or on the web

Sync both devices: first the one with the newer data, then the other. Tap Sync at the top of the Logbook tab, or pull down to refresh, and update Wader to the latest version. A flight with a red cloud is not synced yet; a teal cloud means it is in the cloud. If Downloading Flights keeps looping, the same article explains how to repair it.

→ See Devices & Sync.


Why are some flights missing from my totals or my PDF?

Flights with an amber edge and a MISSING tag are incomplete: one or more required fields are empty. They are not counted in your totals or exported until you complete them. Tap the tag to see what is missing, or turn on Incomplete only in the Logbook filters to list them all.

→ See Flight Validation.

My totals do not match my old logbook or my PDF

Wader counts only complete flights and never estimates missing values. In an export, the date range, the aircraft you pick, Add previous experience and Deduct relief time all change the totals. To match your Dashboard, select all aircraft and the full date range, turn on Add previous experience and leave Deduct relief time off.

→ See Understanding Your Totals.

My hours look lower than before

If you log relief time on augmented crew flights, check whether Deduct relief time is on. On the web it is the switch above your Dashboard stat cards, and on the Export page. When it is on, your totals count block time minus relief. Turn it off to see your full block time again. Your flights do not change.

→ See Understanding Your Totals.

How do I export my logbook as a PDF or CSV file?

Open the Logbook tab, tap the ☰ menu at the top right and choose Export. On the web, open the Export page.

Choose PDF for your authority’s layout (EASA, FAA, UK CAA, SACAA, GCAA or CASA) or CSV for a spreadsheet. Exporting is FREE. Adding your signature to every page of the PDF is part of PRO.

→ See Exporting Your Logbook.

Why is my simulator time not in my flight totals?

Simulator sessions are kept apart from flight time, so they show as their own total in your Dashboard. Log them with the + button › Simulator, not as a flight.

→ See Logging Simulator Time.


How do I log PIC, SIC, PICUS or multi-pilot time?

Choose your role in Function on the flight form (PIC, SIC, PICUS, Dual and others). When the crew has more than one pilot, turn on Multi-Pilot if the flight was a multi-pilot operation.

→ See Flight Form Reference and PICUS Time.

How do I record who flew the takeoff and the landing?

When the crew has more than one pilot, use Pilot Flying (PF) on the flight form to choose who was flying at departure and who was flying at arrival. Your own takeoffs and landings go in the day and night counters. When you export, Add PF/PM to remarks prints this in the remarks.

→ See Flight Form Reference.

How do I log cross-country and IFR time?

On the flight form, set Flight Rules to IFR, VFR or IFR+VFR, and tick Cross-Country when the flight qualifies.

→ See Cross-Country Time.

How is night time calculated?

Wader works out night time from your block times and the sunset and sunrise at your departure and arrival airports. It does not use civil twilight, so it can differ by 20 to 30 minutes from logbooks that do. To set night time yourself, save the flight and tap Edit Times, or turn automatic night time off in Preferences.

→ See Night Time Calculation.

Can I change many flights at once?

Yes, with Bulk edit, part of PRO in the web app at logbook.waderaviation.com: tick the flights in Logbook and tap Bulk edit to set the function, flight rules, night time, aircraft type and more. In the mobile app you can select many flights to delete them: tap and hold a flight card, or choose Select flights in the Logbook’s ☰ menu.

→ See Fixing or Updating an Import.

Can I enter my times in local time?

All times in Wader are in UTC. When you import the Wader spreadsheet template, you can give local times and Wader converts them.

→ See Standard Spreadsheet.

An airport or aircraft type is missing or wrong

Search an airport by ICAO code, IATA code or city, and an aircraft type by its ICAO code (for example B738). If it is still missing or its data is wrong, report it from More › Support Hub with the code and the correct details, and the team adds or fixes it.

A deleted aircraft type still shows in my Fleet

Open your Dashboard and pull down to refresh. The Fleet is rebuilt and the old type disappears.


I cannot sign in, or the reset email does not arrive

Type your email on the sign in screen and tap Continue: Wader tells you whether it has an account and how it signs in. A reset email can take a minute and may land in Spam or Junk. If you still cannot find your account, use Find your account.

→ See Signing in & Account Access.

How do I cancel PRO or ask for a refund?

Cancel where you subscribed: on iPhone or iPad in your Apple ID Subscriptions, on Android in Google Play Payments & subscriptions, and on the web from Manage subscription. Apple and Google decide refunds for purchases made in their stores. PRO stays active until the end of the period you paid for, and your flights are never deleted.

→ See Managing Your Subscription.

I paid for PRO but Wader still shows FREE

Check that you are signed in to the same Wader account you used when you subscribed. On a new phone or after reinstalling, open the PRO page and tap Restore.

→ See Managing Your Subscription.

Can I use Wader on my computer?

Yes. Open logbook.waderaviation.com, choose Yes, I have the Wader app and sign in with the same method you use in the app. Your logbook syncs between the web and your phone.

→ See Wader on the Web.


Where is the airport search?

Airports are in the Briefing tab since Wader 5.0: switch to the Airports view at the top and search by ICAO code, IATA code, city or name. Each airport has its weather and NOTAMs, and its Stats tab shows the runways in use, the approaches flown and the threats pilots report most.

→ See Airports and Stats, My Stuff & Notes.

Where is the preflight checklist?

Checklists are now in the Briefing tab, with your next flight. Open Briefing and tap the checklist on the next flight card.
