LogTen and ForeFlight export checker: 6 totals and 2 currencies from your file

Drop a LogTen Pro tab export or a ForeFlight logbook CSV to see 6 totals and your passenger and night currency under the regulator you pick. The checker reads the file with the Off Chocks app's own import, totals and currency code, so you see what the app would bring across before you move.

Your file is read in this browser tab and never uploaded. To work out night and local times the page downloads the app's airport list (about 0.7 MB), and it counts that a check ran, with the file type and a rough flight count, never the file or what is in it.

LogTen Pro .txt or ForeFlight .csv, up to 25 MB.

How the checker reads your file

  1. The file is read the way the app's upload step reads it: ForeFlight's full export by its Flights Table, with each flight's aircraft taken from the Aircraft Table above it, and any other file with Papa Parse. Its columns are then matched by the app's LogTen Pro or ForeFlight import.
  2. Every row then goes through the app's import engine: dates, times, roles, night, instrument time, takeoffs, landings and approaches, with night and twilight worked out from the app's airport list.
  3. The totals are the app's Logbook totals bar, and the currency is the app's Currency page for the regulator you pick, worked out for today.
  4. Rows the app could not import are listed with the reason, by their row number in your file.

The checker reads your file as if it were going into an empty logbook. Duplicates against flights you already have, a balance forward and your own custom airports are checked by the app at Confirm. It shows the preset currency rules; in the app you can edit every rule.

The sample files are a made-up first officer’s logbook: 892 Boeing 737-800 sectors and 8 simulator sessions, with made-up flight numbers and registrations. Download the LogTen sample or the ForeFlight sample.

Common questions

Does the checker upload my logbook?
No. The file is read by code running in this browser tab and is never sent anywhere. Once the page and the airport list have loaded, you can turn off your connection and still check a file.
Which LogTen export does it read?
Export Flights (Tab), from the Reports tab, Exporters. It writes every flight with every field LogTen holds to a tab-delimited .txt file. Dynamic Export Flights writes only the fields shown in your Logbook tab, so it may leave out columns the totals need.
Which ForeFlight file does it read?
The logbook CSV from ForeFlight on the Web: Logbook, the Export tab, then the blue Export button. Check the full export as it is. Like Off Chocks, the checker reads its Flights Table and takes each aircraft's type from the Aircraft Table above it. A file holding only the Flights Table is read too, without the types.
Why are my numbers different from LogTen's?
The checker counts the way Off Chocks does. Total and PIC leave out simulator sessions, instrument hours are actual instrument time, and currency follows the preset rules for the regulator you pick. A row with a total over 24 hours reads as a totals or brought-forward row and is left out, and the list under the result says so.
Do imported flights count toward the 50 free hours?
Your history doesn't. Flights you flew before you joined Off Chocks and balance-forward totals never count, however you import them. Flights you fly after you join count toward the 50, whether you type them or import them. You can bring your whole LogTen or ForeFlight history across and still log 50 hours of new flying free.
