So, once upon a time we had the VFG for visual pilots and the AIP for IFR & Commercial operations.
The VFG was deleted and was much missed particularly by Private Pilots. Then we had the AIP as two volumes...to make it easier. Then there was a complete re-numbering/chapter naming to ....make things easier.
Then CASA decided to produce a VPG which is great but dates quickly and is not an operational document. The Private Pilots love them.
Now we are going back to a single volume AIP...to make it easier. Looks like they want to be more like Jeppesen!
Then of course there was the old En-route Supplement. Say that phrase to many pilots and they look quizzical and say, do you mean ERSA!
