Boeing produces several manuals specific to each serial number. With respect to flight operations, they are:
Airplane Flight Manual (AFM)
Flight Crew Operations Manual (FCOM)
Flight Crew Training Manual (FCTM)
Flight Attendant Manual (FAM)
Flight Planning and Performance Manual (FPPM)
Of course, unless you have access to the website "MyBoeingFleet.com", which you probably won't unless you are in management, you can't see them...
So the real dilemma is whether your management has actually read them before writing your company manuals!
