LS, I have checked against all the documents you have suggested and still cannot find a reference to say that one must start a stopwatch at the start of taxiing before a flight and stop said stopwatch as soon as taxiing has finished post flight.
What I can find, is that the flight time, which includes taxi time, must be recorded. I can see nothing whatsoever to suggest that the method used by my company is in conflict with this rule, nor have I seen or heard of any indication from CASA that this is not an acceptable means of complying with the rule.
We are logging flight time in a method that is proven to be both reliable and accurate.
You sound like exactly the kind of person that gives CASA a bad name. You have read something into a law that is simply not there and are now running around trying to force that interpretation onto others using scare tactics about prosecution and shouting about how people's careers will be ended.
