10 hour solo training requirement for commercial?

[James Darren]

What is the 10 hour solo training requirement when doing your commercial certificate? Is this solo training after an instructor signs you off? (similar to when you do your PPL training?)

 

[PeterNSteinmetz]

Not instrument rated (just a few sim hours) and not a commercial student. I've wanted to complete some of the 10 solo hours for commercial, but how would I prove that one of these flights (the 300NM XC or night solos) cover the "areas of operation listed under §61.127(b)(1)"?
Or am I overthinking it, since almost all of 61.127(b)(1) is also listed for the PPL (61.107(b)(1))?

You just need to make appropriate entries in the logbook. No need to “prove” it further than that. I would also perhaps add a note that this is for the Commercial requirement, whatever it is. Also keep a list of the dates of the flights for each requirement to make it easier to find them when the examiner asks.
