I have developed a theory about Part 91, and regulatory reform in general.
I note small items have snuck into the AIPs...such as an aircraft may not land until the previous aircraft has landed, is clear of the runway, and is taxi-ing away from the runway in use. (My objection to this is that if the previous aircraft lands, exits the runway, and shuts down due to an issue, technically the incoming aircraft should not land.)
I note in Part 91, to land before the previous aircraft is taxi-ing away from the runway is now a criminal offence.
I wonder if the AIPs have been re-written to include all the stuff that our friendly regulator would like to have happen, and are now re-writing the regs to make non-compliance a criminal offence.
Conspiracy theory of the paranoid? Probably. 20 years in aviation will do that to a person....
