LAS - Licensing, Administration and Standardisation
ORS - Operating Requirements and Safety
Its a 600+ page A5 book with general frequently asked questions on the above subjects that have been asked by licence holders to the CAA.
I was able to pick up a 2002 book for a fiver from the CAA when I visited the 'grey' building. Not sure what it should cost. Give them a call may still have some old (2002) for sale if your after one.
