Hours
The reason that many pilots are doing 60-70 hours per month is that FDB operates to the GCAA FTL scheme, which is in effect copied from the UK FTL scheme.
This only allows 3 night flights in a row. As FDB have flights right through the night, you can expect to do a few days starting at one time have 1 or 2 days off & then be reporting at a completely different time.
The general comments in the FTL about circadian rhythms are ignored - expect to hear "well, it's legal"!!!!
