NDB approach without ADF
Hello,
Yesterday i had a discussion with an IR student who was training NDB approaches.
The aircraft used in training is equipped with a G1000 but not with an ADF.
The training is done using a waypoint (the NDB) in the G1000.
My question: is this legal? (EU regulations)
As far as i'm concerned one is allowed to do this providing you have the conventional navaid tuned as backup, but since there is no ADF installed, for me this aircraft is not allowed to do NDB approaches.
Is this correct or am I missing something here?
Thanks
