The final segment minima values (OCA/OCH, MDA/MDH, etc.) can be encoded using the attributes of the Minima class, which is associated with the FinalLeg through the ApproachCondition class. The following diagram shows the relevant classes and attributes:
The climbGradient attribute of the ApproachCondition class corresponds to the climb gradient of the missed approach legs. It is intended to be used for encoding non-nominal climb gradients, in combination with the aircraft landing category (such as “category A with 2% climb gradient”).
