Fixing or Updating an Import

After an import, check a few flights against your old logbook. If something is wrong, find it in the table below. Most problems are fixed in one of two ways: import a corrected file or change many flights at once on the web.


What you see How to fix it
Wrong function (PIC, SIC, PICUS, Instructor, Examiner) Correct the hour columns in your file and import it again. For some airline sources the import screen has a Your function option: choose the right one and import again. Or, with PRO on the web, use Bulk edit › Set function.
IFR time missing Fill the flight rules or IFR column in your file and import it again, or on the web use Bulk edit › Flight rules › IFR (PRO).
Night time missing or wrong Wader works out night time from the route and block times when it can. On the web, Bulk edit › Night time › Recalculate works it out again (PRO). See Night Time Calculation.
Takeoffs or landings missing Add the takeoff and landing columns to your file and import it again. On the web, Bulk edit › Assign PF/PM shares the takeoffs and landings between you and the other pilot (PRO). To set them flight by flight, open each flight.
Times shifted (local time read as UTC, or the other way round) Delete the flights that were imported with the wrong times, then import the file again with the right time reference. Importing again without deleting first adds the flights a second time, because the times no longer match.
Flights twice Select the extra copies and delete them (see below). Duplicates come from a second import with shifted times, or from a file with only a total time and no block off time.
Wrong aircraft type Correct the registration or type in your file and import it again, or on the web use Bulk edit › Aircraft type (PRO).
Flights missing after import See Finding Missing Flights.

All times in Wader are in UTC. The Wader spreadsheet template has a time reference so you can give the times in UTC, local time or the time at your base. See Standard Spreadsheet.


You can import the same flights again as often as you need. Wader does not add a flight twice: when a flight in the file has block times that overlap a flight already in your logbook, Wader updates that flight instead of adding a new one. The route and flight number are not compared, only the times.

When a flight is updated, these come from the new file, even when the file leaves them empty:

  • Departure and arrival airports, flight number, registration and aircraft type
  • Block off and block on times
  • Your function and the PIC, SIC, PICUS, Dual, Instructor, Examiner and relief times
  • Flight rules and IFR time, instrument time, cross-country time, multi-pilot and the number of crew
  • Night time, which Wader works out again from the route when it can

So a file with an empty IFR column, for example, sets IFR time to zero on every flight it updates. A column you leave out of the file counts the same as an empty one. Make sure the corrected file has every column, filled in.

These stay as you entered them when the file leaves them empty:

  • Takeoff and landing times
  • Takeoff and landing counts and Pilot Flying. If the file has any takeoff or landing count, all four counts are taken from the file.
  • Crew names
  • Remarks
  • Approaches, runways, SID, STAR and transitions, notes and threats
  • Simulator level
  • A flight signed by another pilot is never changed by an import.
  • A file that has only a total time and no block off time cannot be matched: every import adds those flights again.

Bulk edit is part of PRO and is on the web only, at logbook.waderaviation.com.

  1. Open Logbook in the side menu.
  2. Tick the flights you want to change. Use the box at the top of the list to select every flight shown, or Select all … logs in your Logbook to select your whole logbook. Searching or filtering first is a quick way to pick, for example, every flight on one aircraft type.
  3. Tap Bulk edit. It shows once two or more flights are ticked.
  4. Choose what to change, check the preview of your totals before and after, and tap Apply to … flights.
Change Options
Set function PIC, SIC, PICUS, SPIC, Dual, Instructor, Examiner, Simulator Trainer or Simulator Trainee. The function gets the whole block time and the other function times are set to zero. Instructor and Examiner also log PIC
Multi-pilot Multi-pilot or Single Pilot
Night time Recalculate under the rule you choose, or Set to zero
Cross-country time Logs the whole block time as cross-country on flights longer than 50 NM, and zero on the others
Actual instrument A % of IFR time, or Set to zero
Relief time Use total crew or Use block time
Flight rules IFR (IFR time is the whole block time) or VFR (IFR time is zero)
Aircraft type The type for every selected flight
Assign PF/PM For Takeoff, Landing or Both, the share of flights where you were pilot flying. Takeoffs and landings are worked out again

Bulk edit does not change simulator sessions, previous experience or flights signed by another pilot. Changes are permanent: there is no undo.


In Logbook, tick the flights and tap Delete, then confirm. To delete 50 flights or more, you type DELETE to confirm. Flights signed by another pilot cannot be deleted this way.

In the app you can select many flights to delete them. Editing many flights at once is on the web.

  1. On the Logbook tab, tap and hold a flight card. Wader ticks it and starts selecting. You can also tap ☰ at the top right and choose Select flights.
  2. Tap each card you want to add or remove. The top bar shows how many are selected.
  3. To pick every flight in the list, tap Select all in the bar at the bottom. With a search or filter on, it picks only the flights found, so search first to narrow the list, for example by aircraft or airport. Tap Deselect all to start again.
  4. Tap Delete in the bar at the bottom and confirm.
  5. Tap Cancel at the top to stop selecting without deleting.

You need an internet connection to delete flights that are saved in the cloud. Deleting cannot be undone. A flight a crew member shared with you is only removed from your logbook.

To delete or start a flight from a single card, see Swipe Actions.
