Descending once cleared for approach
My first post, here goes. On a recent Europe trip, we were descending to FL 80, proceeding as directed to an iaf at a French airport. Then we were cleared for the ils approach. Is it ICAO procedures that further descent levels or altitudes are up to the pilot (for eg, 25 mile MSA)? Is there any online documentation that details this, similiar to the US AIM?
The details were LFOK, Vatry Chalons, France, Ils Z RWY 10, iaf was KELON
