I'll try my best, although I don't work for them my best mate is an F/O, I'll let him know about your question and get some answers if you need them. For now though...
At the moment they operate two shifts a day, early and late. At Plymouth, early shifts have a report time of around 06:00 depending on your flight and you generally finish around 13:00. Late shifts have a report time of 12:00ish and finish about 21:30. There's no uniform pattern to the rosta e.g. no "5 on 4 off", generally out of 5 days a week you get 3 flying and 2 home standby, there is no airport standby. With the introduction of new routes at the end of April there are going to be changes in the number of shifts a day. The rosta generally seems fairly flexible, with you being able to request a maximum of 4 specific days off a month, you're also allowed to do mutual swaps.
You need to be within 60 minutes of your designated base.
Hope that helps
