This requires that each runway should have a takeoff climb and approach surface which should:(a) Rise from the end of the runway strip; and(b) Be obstacle free above a gradient of 1:20; and(c) Extend horizontally 1200 m from the inner edge; and(d) Have sides that are splayed outwards at the rate of 1:20; and(e) Not turn before 300 m from the inner edge, if a turn is necessary.Update Frequency: As required.Point of Contact:Waimakariri District CouncilLineage:Data was digitized using aerial imagery and LINZ parcel data.
