In this paper, the differences and relationships between these surfaces are addressed. The conditions for the use of each criterion are discussed. WebTERPS uses an obstacle climb surface (OCS) for this same purpose. OCS slopes upward at 152’/NM or 40:1 ratio. On top of this surface is added the required obstacle clearance (ROC). ...
