Lawyers love a time consuming sh*te-fight over the meaning of a word.
se Fice re Caper and "usually"..or was it "generally".
"terrain".... a tract of country/land. No mention of the liquid stuff there.
"water"..... a liquid compound of oxygen and hydrogen. No mention of any hard stuff there.
How a word, and/ or the use of, is interpreted can decide whether someone gets hung...or not.
If it does not specify both then the regulation is poorly thought out and badly written...whose fault is that.? And we suffer with more enough of that convoluted gobbldegook as it is.
The psuedo-legals that cobble up these crap regs are failing the requirement that the regs must be written for the layman/user/us...and not just legal vomitus for lawyers to play with.
The bureaucrapic way is "complexitization"...creates more work, takes more time, costs more money..and the KISS principle is given the kiss-off.
And GA suffers accordingly.
