     Provided that, if the aircraft is flying in a combination of such circumstances, the scales of equipment shall not on that account be required to be duplicated.

     2. The following items of equipment shall not be required to be of a type approved by the Director-

     (a)      the equipment referred to in Scale A (ii);

     (b)      first-aid equipment and handbook, referred to in Scale B;

     (c)      time-pieces, referred to in Scales G, H and J;
