Logging with ADS-B

Wader can fill a flight for you from ADS-B data: the route, the aircraft, the OUT, OFF, ON and IN times and the runways. You type a flight number or a tail number, Wader does the rest.

Plan ADS-B flights
FREE 20 flights filled from ADS-B, including the sectors of a multi-sector day
PRO Unlimited

When your 20 FREE flights are used, the ADS-B drawer shows what it would fill in, with Upgrade to PRO.


  1. Tap + and choose Flight.
  2. Enter the flight number or the tail number, and set the date.
  3. Tap ADS-B at the top of the flight form.
  4. If more than one flight matches, choose yours. Flights already in your logbook are marked In logbook.
  5. Check the details in the drawer: status, route, aircraft, the four block times and the runways.
  6. Tap Apply to flight, then Save.

Leave Automatically complete your log on, and Wader keeps updating the flight in the background until it is complete. This lets you log an upcoming or in-progress flight now and have its real times filled in after you land. Next update shows when Wader looks at the flight again.

Open the flight and tap ADS-B again to see the data it holds. You can Refresh it once every 5 minutes.


Log a whole day of flying in one go. Every sector becomes its own flight, with the same crew and its own Pilot Flying and Pilot Monitoring.

  1. Tap + and choose Multi-sector.
  2. Choose how to find your sectors:
    • Flight number: enter the Date (UTC), the day’s flight numbers (tap Add sector for each one) and where the first sector departs. Each next sector leaves from where the one before landed. Best when your airline changes aircraft between sectors.
    • Tail number: enter the registration and the date. Wader finds the legs that aircraft flew starting from 00:00 UTC on that date.
  3. Set the crew once for every flight.
  4. Tap Find flights, tick the sectors you flew and tap Select flights.

Each sector counts as one ADS-B flight. On the FREE plan, Wader tells you before you search if you have fewer free ADS-B flights left than sectors.


Your Flight number prefix tells Wader which flight numbers belong to your airline. Set it in the Logbook tab: tap ☰, then Preferences, and fill in Flight number prefix under Logbook defaults.

On a wet lease, a flight often starts out under the operating airline’s flight number and is renamed around departure to your airline’s number. When the new number matches your Flight number prefix, Wader switches the flight number on your flight automatically and keeps updating it.
