Properties:

Properties Definition Type
isAssessmentSurfacePenetrated A code indicating whether the controlling obstacle penetrates the assessment surfaces.

Boolean

adjustment Operational factors applied to obstacle clearance altitudes to produce the safest usable altitude. AltitudeAdjustment
obstaclePlacement Location of obstacle in relation to a given point. ObstaclePlacement
verticalStructureObstruction Vertical assessment controlling obstacle. VerticalStructure
slopePenetration A value calculated by dividing 102.0 (a constant) with the angle of the glidepath.

Angle

requiredClearance Required altitude adjustment above any obstacle or terrain within a defined safety buffer region. ValDistanceType
minimumAltitude The value of the minimum obstacle clearance altitude. ValVerticalDistanceType
isControlling Indication whether it is a controlling obstruction for the associated obstacle assessment area.

Boolean

isCloseIn Indication whether the obstruction penetrates the 40:1 OCS, therefore requiring a climb gradient to 200 feet or less above the departure end of runway.
