       1For subregulation 174A (1) of CAR, this clause specifies the SSR transponder equipment that must be carried on certain aircraft before they undertake a VFR flight.
       2A serviceable Mode A and Mode C SSR transponder must be carried on an aircraft that:

       (c)              operates under the VFR and within ATC radar coverage, in Class A airspace below FL290, in Class B airspace, or in Class C airspace.
Note   Carriage of a Mode A and Mode C transponder does not remove the requirement to obtain CASA approval to operate in Class A airspace: see subregulation 99AA (3) of CAR.
       3Clause 2 does not apply if the aircraft carries serviceable Mode S transponder that meets the standards set out in in Schedule 1A.

       (c)              has an engine-driven electrical system capable of continuously powering a transponder; and
       (d)              operates under the VFR in Class E airspace, or above 10 000 ft AMSL in Class G airspace.
       5Clause 4 does not apply if the aircraft carries:
       (a)              a serviceable Mode S transponder that meets the standards set out in in Schedule 1A; or
