Thank Chr!st you guys are pilots and not lawyers.
If we want to play lawyer, then we have to look at not only the one section of the regs (quoted above to give you the rough idea) but we also need to look at those regulations head of power (the Act) and also how the courts interpret the words.
Example: a rugby club mate and law student of long ago, once found a South Australian statute allowing Cab drivers to relieve themselves against the rearmost, kerbside wheel of their Cab. Dated from the 1870's when a Cab driver was taking a risk leaving their stock in trade, not to mention their horse, unattended when relieving themselves.
Quite legal he thought. So one night, this law student/cab driver parks his Yellow Cab falcon in King William Street rank, and puts his theory to the test.
And ends up in the Angas Street watch house.
You would have to be a pretty confident
VB or any other jet Captain to risk 200 penalty points, disciplinary action from your airline, etc, based on a 'bush lawyers' interpretation of those words alone.
Without referring to my company's Transport Security Procedures (a company document required under ATSRs 2.29 and 2.39) I'd say the intent of the reg is -- nobody on the flight deck that isn't operating crew, company staff, or CASA.
