Software for SOPs/Flowcharts/Checklists etc.
 

I´m about to venture into unknown terrortory...to write down our SOPs...

I want to use the best possible software for that undertaking...in the process I´d like to rewrite the absolute awful checklists for our Cessna done by FSI.

Anyone got a suggestion for a real good software for this ? (preferably for MAC OS, if I absolutely have to I`d even use Windows)

A checklist needs only the simplest software. Pages will do you nicely. If more sophisticated software is needed you are kicking the arse out what should be a very simple job.

All of the software that you need is between the ears. Few operations are so standard that by copying someone else’s checklist, SOPs, or software, they will reflect your safety culture and methods.
The UKCAA and FAA have written guidance on the preparation of checklists - http://www.caa.co.uk/docs/33/CAP676.PDF
