Plagiarism
I spent several years as a Training Manager with a specific brief to write the technical manuals for the particular operation of the Company. These covered everything from the DC-6 and Electra to the A300-600. Whilst it is inevitable that some of the information would be the same as included in the Manufacturers Manuals, I always felt that a rewrite (still holding essential information) was more "user friendly". Without being too smug about it, I was congratulated by two different directors on producing a "probably the best manual " that they had ever seen.
So what I am trying to say is that whatever you call it, some plagiarism is inevitable BUT how you say those "essential" facts, makes the difference.
What I couldn't understand (a couple of years ago) is why one aircraft I travelled on carried the flight safety card for a totally different aircraft.
