AOM-0208-B — Dynamic Mobile Areas (DMA) of types 1 and 2

Dynamic mobile area (DMA) is an integral part of the MT described by a 4D data set. DMA constitutes a defined volume of airspace that satisfies specific operational requirements from different Airspace Users (AU).
There are two types of DMA that have been identified as geographical centric:
DMA Type 1 is a volume of airspace of defined dimensions described as an integral part of a MT at flexible geographical locations agreed upon in a CDM process satisfying Airspace Users requirements in terms of a time and/or distance constraint parameters from a reference point as specified by AU (e.g. Aerodrome of Departure).
DMA Type2 is a volume of airspace of defined dimensions described as an integral part of a MT and agreed upon in a CDM process satisfying the Airspace Users requirements. This volume of airspace can be planned and used at any geographical location along the trajectory.
The MT profile description will allow extraction of DMA 4D dataset to be used as an input into NM system for DCB and DAC processes. It will facilitate NM to optimise ATM Network configuration while minimising the impact of DMA on the expected traffic
