What is Understanding OCA/H in Aviation about?

Obstacle Clearance Altitude/Height (OCA/H) is the minimum altitude an aircraft must maintain to avoid obstacles during approaches, calculated based on the highest obstacle and aircraft performance. The OCA/H is determined by state authorities and varies for precision and non-precision approaches, with specific references to runway thresholds and aerodrome elevations. For visual maneuvers, OCA/H is based on the highest obstacle in the circling area, ensuring safe descent without infringing clearance criteria
