If you have access to Jepp through your airline go to the text book, select the section you want ie Meteorology, highlight the first page then (holding down the shift key) the last page (this should have highlighted all the pages). Now use the file print command in the Jepp browser and when it has downloaded the file save it instead of printing. You now have a pdf version of that section.
Naturally the normal cautions about updating the info etc and not to use without checking validity apply but if all you want is a copy to read on a laptop at home or in a hotel room it should be fine.
