This is a really good discussion item in the P3 community right now. For those outside of our community, go ask your Safety officer to pull our SIR and read through it. Quite a few CRM take aways as general discussion items. Unfortunately, due to the nature of SIR releasability, it will not be posted on this site.
One of the "hot topic" items in the P3 community right now is currency and proficiency. There are varying metrics out there from 3710, NATOPs and Wing stan notes that set different bars of minimum hours/approaches/landings. What does YOUR community count as a "minimum" hour requirement to fly/sign for the aircraft? Is it a sliding scale based upon hours or quals, ie the more senior or experienced you get, the less hours you need to maintain proficiency? And what constitutes proficiency? I can rack up quite a few hours on repo flights, but does that make me safe to go out a fly as an IP and do funny landings (3eng, 2eng, no flap) instruction? hmmm?
