mda 320

hi, may be this could be a silly question but since I take the trainning for A320 when I set minimus to land even in ILS I set mda in stead of dh does some body know why??

Because Cat 1 approaches are referred to barometric altimeter.

.. more particularly, until the aircraft is over the runway, the rad alt is not of precision value.
