Quick question, I know the Pilot oxygen requirements have for part 135 have traditionally been the standard FL250 Pilot out of the seat and FL350 one Pilot on oxygen. I read an article that the FAA has amended the requirement to FL410 for part 121 operations, but could not find it addressed to part 135? I tried a search on the APC part 135 thread to no avail.

Anyone have any info/help on this?

thanks!
