Descend to MSA when "cleared approach"
Imagine this:
You are cleared on a radar heading to 4000 ft and you are outside FAF on an ILS approach. Approach control clears on this heading for the ILS approach. Platform altitude is say 3000 ft at FAF. Can you legally descend to the MSA before you are established? I can imagine problems if you did that at certain busy airports. I would normally maintain 4000 ft until the glide. Some people told me that "cleared approach" allows you to descend to MSA and disregard the previous altitude clearance. Opinions ?
