Circling approach not published at RCTP
RCTP,RWY 05 ILS approach chart stated that circling approach (MDA)minima not published and to NW of runway 06/24 only. While GNSS approach chart stated that circling approach not authorized. Other approach charts give circling minima. Question is if we want to make a circling approach and no minima published,what is our MDA? Thank you.
