There are numerous approaches where the procedure points you at other traffic.
Imagine a high performance a/c executing a missed approach off the Hamilton Island Rwy 32 VOR.
Ayers Rock NDB is another and OCTA where high performance equipment operates.
My biggest concern is situations such as this where a published procedure brings you into possible conflict.
What would you descend to in the holding pattern if there was an a/c ahead on the approach ?
