Not sure where your 'Dark Side' Ops are, but JAROPS requires JAR airlines to include such procedures in their Ops Manuals, and I don't think that would change with 'EUOps'.
8.3.3
Altimeter setting procedures including use, where appropriate, of
- metric altimetry and conversion tables,
and
- QFE operating procedures.
Do you have such? They are written so that both you and your co-pilot will know the SOP altimeter setting procedure in contrast to our US colleagues who all have their own individual 'recommended' procedures, it seems.
