When I need clarification of any words/meanings contained in the CAR's, I go to CAR (1988) Part 1 (2) Interpretation. That is until I got to para D.5 which says:
"Where any rule contained in the provisions of Division 2 of Part 11 or in the provisions of Parts 12 and 13 contains a provision similar to that of a rule contained in the Rules of the Air adopted in pursuance of the Convention, but a distance which in the last-mentioned rule is expressed by kilometres, metres or centimetres (as the case may be) is in the first-mentioned rule expressed in miles, feet or inches, an aircraft which, in respect of that distance, complies with the last-mentioned rule shall also be deemed to comply with the first-mentioned rule." <img src="confused.gif" border="0">
I know I am just a boggy aviator and not a lawyer, perhaps I need to be one to make any sense out of this!
