CLIMB GRADIENT TABLE

In order to assure obstacle clearance, controlled airspace containment or safe integration of procedures, some Standard Instrument Departure Procedures in the UK require Climb Gradients in excess of 3.3% to be achieved. Procedure design Gradients are annotated as percentage climb gradients where necessary. The Table below provides a conversion to rates of climb for various speeds.

		ground speed (kt)	75	100	150	180	200	210	250
