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.

2.EUROCONTROL (2010) Airport CDM Operational Concept Document, Ed. 3.1

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

Variable Taxi Time

• 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.

Note

In the ATM operational concept, three classifications of airspace users are considered:

a) ICAO-compliant manned flight operations (the largest segment by far)

b) ICAO non-compliant manned flight operations; and

c) flight operations of unmanned aerial vehicles (UAVs).

ICAO-compliant manned flight operations are those conducted in accordance with ICAO provisions (e.g. SARPs, PANS). ICAO-compliant airspace users include:

a) all civil aircraft operators (i.e. those engaged in commercial air transport (passenger, mail and cargo services)), aerial work, air taxi operators, business aviation, private air transport, sporting and recreational aviation etc., and

b) the portion of States’ users operating State aircraft using civil air traffic rules.

ICAO non-compliant manned flight operations are those conducted by State aircraft which cannot comply for operational or technical reasons.

Flight operations of unmanned aerial vehicles (UAVs), a growing segment of airspace users, include both civil and military applications of UAV technology. In certain situations, UAV technology is seen as a more cost-effective solution than the use of conventional aeroplanes or helicopters.

Note

A data warehouse contains data which is built out of separate internal and/or external data sources where the data is integrated in a consistent manner. The database design of a data warehouse favours data analysis and reporting in order to gain strategic insight and to facilitate decision-making. A data warehouse contains “fact tables” and “dimension tables” which may be arranged as a “star schema” or a “snowflake schema”

Definition

1. (SESAR) the time computed by the FMS for the flight arriving at a point related to the destination airport

2. (ICAO) For IFR flights, the time at which it is estimated that the aircraft will arrive over that designated point, defined by reference to navigation aids, from which it is intended that an instrument approach procedure will be commenced, or, if no navigation aid is associated with the aerodrome, the time at which the aircraft will arrive over the aerodrome.

For VFR flights, the time at which it is estimated that the aircraft will arrive over the aerodrome.

Note

When an aircraft is flying to a TTA, the FMS will still provide an estimated ETA. When an aircraft is flying to a CTA, the ETA will be replaced by the RTA.

When negotiating a CTA with the ground, the FMS provides the bounds for a feasible RTA, expressed as ETA(max)/ETA(min). (source: Episode 3)

KPI

Definition

1.A clearly defined measurement indicator considered to be of the highest importance for measurement in validation exercises and used for validation assessment.

2.[performance indicator] Current/past performance, expected future performance (estimated as part of forecasting and performance modelling), as well as actual progress in achieving performance objectives is quantitatively expressed by means of indicators (sometimes called key performance indicators, or KPIs).

2.ICAO (2009) doc. 9883, Manual on Global Performance of the Air Navigation System

Note

To be relevant, indicators need to correctly express the intention of the associated performance objective. Since indicators support objectives, they should be defined having a specific performance objective in mind.

Indicators are not often directly measured. They are calculated from supporting metrics according to clearly defined formulas, e.g. cost-per-flight-indicator equal Sum(cost)/Sum(flights). Performance measurement is therefore done through the collection of data for the supporting metrics. (same source)
