Time accountable
Heavy crew time accounting. All Duty Time is Duty Time, time at controls is irrelevant. This break down of Time at Controls & Time on Duty was a practice used some many years ago by US FAR91 carriers, I saw many a time where one crew (Capt/FO/FE + Cabin) operated ETAR/RMS Diego Garcia live and logged. 2 hr T/R then return as a backend ferry. Nothing logged for the return sector, just a pay log. No FTLs for FAR 91 ops.
Also have seen OEDR/DHA-ETAR/RMS-KSWF/SWF-KAOK/OAK in one hit with only the RMS/SWF sector logged, this again with one 3 man crew, long day what.
I had thought that these practices had been torn apart, seems not, I'd hate to be one of the front line crewing folks in your little bit of the NEW Sandpit-High Rise-Car Park-Shopping Mall, what was a good beach/creak areana.
I was in the original!!
