It means that they are making life easier for operators (although not easier to understand for the barely literate).
Currently your SMS manual and your Human Factors/Non-technical skills course is approved by CASA and once approved it is set in stone.
The whole point of SMS ad Human Factors courses is that they are supposed to evolve with the business and with experience - the normal CASA process means that you need to submit changes to your FOI or a subject Matter Expert for them to approve.
This is invariably followed by a to-and-fro over the spelling of "colour" vs "color" and "hamonise" vs "harmonize" and takes 12 months at the end of which CASA slaps you with a NCN because you haven't made timely amendments to your manual suite as required by CAR 215.
By removing the requirement for CASA proof-reading and sub-editing they allow the operator to get on with business.
