Hmmm! The working time directive for civil aviation is new since I was last involved with airline crew scheduling. Interesting. The rules for annual working time limits and number of rest days didn’t used to appear in CAP371 or the airline’s flight time limitations scheme.

CAP371 in fact goes into more depth on restrictions on duty periods, etc. In fact, for anyone desperate to understand aircrew work regulations the following is the definitive guide:

Wow! Looking through that brings back some memories!

There are similar but slightly less restrictive rules for cabin crew. I can’t remember the details, but the document linked above will provide the answers if you’re desperate to know exactly what they are.

FWIW, the absolute limits on flying hours (in 28 days and in a year) for flight deck crew are detailed in section 21 starting on page 13.
