To be fair Nigel, even Europe's ultra low cost airline use 2 in the FD method at all times.
Understood - but have they paid for the full Phase 2 measures? Or just stuck with Phase 1?
If the latter then the 2 CC is required, and avoids asking the question of "why" they are there
Are there airlines out there requiring 2 crew
and have Phase 2? (not suggesting we name them...)
