In my company we have a problem that we cannot understand completely, because we cannot find the answer.
If I don't have the runway in sight at the circle minimum (MDA) on an ILS approach, I must immediately execute a missed approach or can I level off and maintain the circle minimum (MDA) and continue inbound until reach the MAPt by DME or timing block (don't have DME) and missed approach?
If a RVR is published in the chart, normally it is RVR at MAPt right? For ILS (precision approach) it is clear that MAP is at the DA. LOC (Non-precision approach) uses MDA at MAPt by DME or timing but for circling where is a MAPt? Use same Non-precision or use circle minimum (MDA) on glide?
If we fly ILS for circling, is it a precision or non precision approach?
