SESAR Concept of Operations Step 2 Edition 2014 (Ed. 01.01.00)
The AMAN is designed to deliver a sequence with the required spacing to the runway but this is often translated into a time to be achieved at one or more Metering Points (MP) with the aim of providing Approach Controllers with pre-sequenced flows of traffic which are then manually integrated.The Metering Point (MP) at which the sequence should be stabilised is expected to be geographically defined (there may be multiple MP points at a similar distance from the runway).
