Accessing data in Blackbox and User log files

[TLNZ]

Hi

The balackbox and user log data files record lots of data, but only some columns are populated with data. We need to access for a Rotax 912is engine either CHT or coolant temperature data. Is there away to set up what data sources are logged and populated in these files?

I can't find anything around this topic in Appendix F of the manual nor in the related sections 7, 3 and 4.

Thanks

John

Try https://www.savvyanalysis.com/ for engine analysis. You can select the engine variables to display on the graphs - slick!

I wish it could be used for all the parameters in the Dynon files, but I don't know of any website or program that does it.

There are some columns from the the 912 iS's ECU that may not make it to the data log. CHT isn't a parameter that SkyView gets from the ECU (it may or may not be in the CAN data, but we don't display it since it's not used for operations). Coolant is likely not in the log because it's not one of the "core" engine instruments and it's not being sourced from the EMS module. There isn't a way to get that data in the logs. I believe Rotax does have software that can connect to the ECU for development work, but you'd need to go through Rotax channels to inquire about that.

Dynon, is there a way I may encrypt the Skyview log files on the device? I prefer to choose who has access to these. How can I either encrypt them or prevent them from being recorded in the first place?

Skysailor,
There is no way to encrypt the files inside SkyView.

You can also not turn off data logging. There are three data files inside SkyView which are always recorded:

1) User datalog. This has a configurable rate from 16Hz to 1/10th Hz. This can be cleared manually with "clear all data"
2) Recent flight log. This is the last 15 minutes and is always at 16Hz. This can be cleared manually with "clear all data"
3) Dynon diagnostic log. This has an unpublished data format, and has data for about 2 hours of operation. It cannot be cleared.

Dynon makes no statements that "clear all data" would make the data unrecoverable from the system if you had physical access to it and wanted to recover data directly off the storage device.
