(say 3nm, forget the 2.66 for Cat B that's rubbish)
If you're such a girl wally you need more than 2.66 in a King Air, use cat C speeds then you have yourself covered in the event of a prang
But seeing as when at or around 2000ft & still outside of the circling area & not vis with EN's rwy 17 PAPI you are actually visual with ML's rwy 27. So would it be fair to say that you could decend blw 2000ft even though outside EN's requirements whilst observing ML's PAPI on rwy 27 until you are within the EN circling area & or are visual with EN's rwy 17 PAPI then change from one to the other & still be within the legal requiremnts? Sounds complex I know but draw it out if need be
As far as my understanding the circling area is based upon the tangents from the runway that you are descending to. You cannot leave the 25nm MSA until you are established in the circling area (for a visual approach) determined by the tangents of the threshold of the runway that you are using. You may then descend to circuit height once established in the circling area or continue on a normal 3 degree glide slope from the MSA to intercept the normal final approach course.
Remember at night you fly as if you were in IMC
