For example, we make instrument NDB approach for RW36 and we use for it respective chart. Then we make circling for RW18. Is circling MDA on the chart for RW36 in right lower corner or should we refer for MDA to RW18 chart?
Back to the originial question, and a simple answer...
Example: Rwy36 has a instrument approach. Rwy18 does
not have an approach. You complete an approach for Rwy36, then Circle for Rwy18.
Which of the only ONE available charts would you use, and which MDA is associated?
Simple enough answer?
