This could be out of date now, but previously it was 2/3 nights in the IOM, a Düsseldorf split duty, and the Brussels contract which is a mix of positioning or flying yourself out, then 4/5 day trips.
Then honestly, unless it's changed, which I hear it hasn't, it was anywhere crewing decided to send you that day, (any base on the network) sometimes position, sometimes a taxi, sometimes a hire car, 1/2 nights out of base.
I always found it was best to just regard all days in work as days away from home, regardless of what your roster initially said, then you couldn't be dissappointed. Works for some, not so much for others.
