Yes for "nornal" day off that ends at midnight.

PWA uses the term "non fly day" and it don't say "noon"...it says "12 hrs prior"

So yes, when your XX day ends at midnight, "12 hours" prior is noon, but the nuance is that this applies to *any* non fly day (other than vacation), namely 30hrs of rest and PB/PR days.

So a pilot can be used as early as 10 hours after their 30hrs of rest or PB/PR day ends, but scheduler has to place it on your scheudle NLT "12 hours" prior, and that 12 hours prior isn't going to be noon because more than likely, the rest/PB/PB day isn't ending at midngiht.

SideStick: I beleive you understand the nuance but I posted it for others who may not.
