Definition
An application that allows airlines to prioritise flights by exchanging the slot of one flight with the slot of another.
Initially limited to flights within the same airline, it now gives airspace users the opportunity to exchange the departure order of any two flights from different airlines penetrating the same constraint (airspace volume, arrival airport). This allows AUs, within commercial agreements, to reduce the delay of a commercially sensitive flight at the cost of another flight.

Degraded weather condition: a condition which might have a significant negative impact on airport performance unless a proper response is organized (i.e. the selection of an airport operating mode to respond to given degraded conditions and eventually the use of additional airport resources such as de-icing/anti-icing services). This would be the case when visibility is poor and/or in case of freezing conditions, precipitations, etc.

Note
Implementation of Airport CDM allows each Airport CDM Partner to optimise their decisions in collaboration with other Airport CDM Partners, knowing their preferences and constraints and the actual and predicted situation. The decision making by the Airport CDM Partners is facilitated by the sharing of accurate and timely information and by adapted procedures, mechanisms and tools.
The Airport CDM concept is divided in the following Elements:
• Information Sharing
• Milestone Approach
• Predeparture Sequencing
• Adverse conditions
• Collaborative Management of Flight Updates
NM Glossary (2014):
Is about partners (airport operators, aircraft operators/ground handlers, ATC and Network Management) working together more efficiently and transparently in the way they work and share data. It aims to improve the overall efficiency of operations at an airport, with a particular focus on the aircraft turn-round and pre-departure sequencing process. One of the main outputs of the CDM process will be more accurate Target Take Off Times which can be used to improve en route and sector planning of the European ATM Network. This is being achieved through implementation of a full set of Departure Planning Information messages (DPIs) sent to Network Operations.

DMA
Definition

Note
There are two types of DMA that have been identified for Step 2: DMA Type 1 is a volume of airspace of defined dimensions described as integral part of MT at flexible geographical locations agreed upon 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 integral part of Mission Trajectory and agreed upon a CDM process, satisfying the Airspace Users requirements. This volume of airspace may be planned and used at any geographical location along the trajectory.

The essence of the MergeStrip concept is that, in an extended environment, a dynamic system can be used to create relative spacing instead of a static map element with fixed lateral flight path.
...
MergeStrip components:
•Common route, for example final
•Merge points
•Relative Spacing Tool (here: plots on an imaginary centre line)
•High level concept of operation
•delaying manoeuvre if necessary (speed control or vectoring)
•using FMS capabilities, optimised flying towards one of the merge points
•speed control for maintaining relative spacing

The separation to keep aircraft operating safely on final approach.
Examples are minimum radar separation to keep risk of collision to an acceptable safe level and wake turbulence radar separation to keep the risk of an adverse wake turbulence encounter to an acceptable safe level.

Definition Source
SESAR doc. 06.08.01 Operational Concept Description (OCD) and Operational Service and Environment Definition (OSED) for Time Based Separation for Arrivals (TBS), Ed 00.01.02 , 2013
Note
The TBS rules are based on a Ground Speed Profile conversion from applying the DBS rules in low headwind conditions. The ground speed profile conversion is based on a reference airspeed profile over the distance based separation to the runway landing threshold that the ICAO DBS rules are applied.
The reference airspeed profile is aligned to a 150kt IAS standard reference landing stabilisation speed profile to the runway landing threshold and is aligned to a 170kt IAS standard procedural airspeed profile to 6NM from the runway landing threshold prior to landing speed stabilisation.
