At the moment the rules say you require an ADF - You need to read Schedule 5 of the ANO. When looking up the equipment scale it's scale "F" that applies:
Scale F
Radio communication and radio navigation equipment capable of enabling the aircraft to
be navigated along the intended route including:
(a) automatic direction finding equipment;
(b) distance measuring equipment; and
(c) VHF omni-range equipment.
There is talk of it changing - but the wheels of bureacracy grind oh so slow.
The thing is - the only person who knew you didn't have an ADF would be you, especially with a G1000 fit.
