RSVA (0000-1159 local)
RSVB (1200-2359 local)
RSVC (1600-0359 local)
RSVD (0400-1559 local), don't think there's any of this in SDF but could be wrong
There are also Blank Reserve lines where the company can basically build a reserve schedule after reserve days drop due to conflict, and Airport/Hot Standby Lines.
On VTO lines, there can be Long Call-Out, where a crewmember is notified between 0800-1400 local with a minimum 16:00 notification prior to report, and there are also a subset of VTO lines called VTOR that can include trips, callout reserve, and standbys (but no LCO).
What kind of "angst" is going on over 'der with regards to reserve?
