| DA | A specified altitude in the precision approach or approach with vertical guidance at which a missed approach must be initiated if the required visual reference to continue the approach has not been established. |
enum value |
| OCA | The lowest altitude above the elevation of the relevant runway threshold or the aerodrome elevation as applicable, used in establishing compliance with appropriate obstacle clearance criteria. |
enum value |
| MDA | A specified altitude in a non-precision approach or circling approach below which descent must not be made without the required visual reference. |
