Fiske,
The best answer is to keep your head down and do what you are told at first. However I believe it is you who is personally responsible for ensuring you keep within the FTLs. There is actually no legal limit for duty time. Each Aircraft Operator's Certificate (AOC) holder has their own scheme. The process is that when applying for an AOC the company devises their own FTL scheme to suit their needs. They then submit it to the Campaign Against Aviation (CAA) for approval. Once it has been approved everyone in th ecompany must adhere to it. In practice the CAA will not approve a less restrictive FTL scheme than is dictated in CAP 371 Jan 04 edition.

FTLs are fairly rigidly enforced and I suggest you read your companies own scheme.
