Hi,
An average month is very varied,you can expect:
1/a five day trip to one of the africas
2/possibly a three day job to africa
3/lots of out and backs
4/some standby.
5/ eight days off (occasionally 10 if doing extended duties)
In the winter the weekends are dominated by out and backs to ski destinations.
Flying 50-60hrs a month at present so not overloaded.
Hope that helps
