In Canada, the FPV drone must to registered.  Owners of registered drones are compelled by law to keep a flight log.  My many other DJI drones keep a flight record in their flight app (Go, Go4 & Flight) which I transcribe to an Excel spreadsheet.  The DJI FPV and Avata drones do not as they are not controlled via an app.
Is it possible to create an automated flight log from an FPV or Avata drone?

To me, it should be possible to connect an FPV or Avata drone to the Flight app download the flight info, and create log entries.

Hi, Hummingbird.UAV. Thank you for reaching out. You may synchronize the flight records using the DJI Fly and then export them from your phone. Below are the details:
How to synchronize flight records:
1）Please make sure that the DJI FLY App is version V1.3.0 and above.
2）Connect the DJI Goggles to the DJI Fly app through the following methods:
Method 1: You can connect the DJI Goggles to a smartphone via an OTG cable and a Type-C or Lightning cable.
Method 2: You can connect the DJI Goggles to a smartphone via a Type-C to Type-C PD Cable or Type-C to Lightning cable.
3）When the “sync flight data to the cloud automatically over Wi-Fi and view it on other devices” prompt appears, it is recommended to turn on the automatic synchronization flight record function; it can also be set manually, the main interface [profile]>[Settings]>[Sync Flight Data]>[Auto-flight Records]. As shown below:

Thanks, Gamora, worked for me.

Related questions, what controls when the goggles will download logs to a phone?
Or is there a way of forcing the download?
I ask because sometimes it starts straight away with a message that reads
"Synchronising flightrecords from goggles to your local device x% complete. "
and  sometimes it does not.
Also sometimes it appears to stick at a percentage and I am never sure if it has lost connection through a cable disconnect or if it is doing something else.
Just now it appears struck at 75%.

What is the source of the "Black Box Data"?
