The regulations are "Clear": Clearly we are all criminals! The regulations are concise as in 'to the point', the point being only Military and Airlines should be flying!
You know the regulations are completely incomprehensible when you ring CASA for an explanation and even the guy who wrote the original regulation cannot understand it! Their comment was "it was fine until it got sent to Legal" (this actually happened!!!!)
So, no, the current regulations are not clear and concise by any normal meaning of those words.
