Cooperative Traffic Management
Improvements that directly interact and can not be addressed independently:
Use of Occupancy Counts by ANSP/FMPs to better assess demand and minimise need for regulation (e.g. Mandatory Cherry Picking, STAM Ph1, some ANSPs use since 2011)
System Supported ATFCM Coordination for all actors involved in establishing ATFCM measures
Predictability improvements by addressing tactical deviations from the filed Flight Plan (ongoing since 2009)
Target Time operations to enhance predictability and in support of arrival sequencing

Using occupancy counts for STAM & MCPTo further reduce the need for ATFCM measures
5
Use of Occupancy Counts – STAM and MCP
Wider use envisaged for benefit of AOs and network performance (at least EUR core by 2015, potentially all FMPs after that)
=> Basis for STAM Phase 2 (see later item)
Demand-Capacity balancing to identify needed ATFCM regulation => NMOC and FMP coordinate with AOs and Airports to reduce need & impact.
Still used most: “hourly Entry Counts” => all flights that exceed declared capacity to be regulated.
Occupancy Counts – more accurate demand picture => more focused solutions: only address specific flights.
STAM Phase 1: local flow control measures (e.g. TONB, MIT, etc) based on Occupancy Counts to prevent /remove current regulations – in use by some FMPs with very good results

Mandatory Cherry Picking (MCP)
Enables limiting an ATFCM measure, addressing short peaks in ATC en-route sectors or Aerodromes, to only a few “cherry picked” flights instead of all flights that would normally be subject that regulation
Only the flights subjects to that measure will receive a CTOT from NMOC.
all other flights that would normally be captured in the regulated period are excluded (i.e. no slot!).
Results 2013 MCP trial (MUAC & Reims and NMOC, referred to earlier today):
=> 130 flights regulated instead of 2126 flights, saving 4666 delay minutes
Towards permanent procedures for short term benefits.

Predictability Reducing the gap between the planning and execution of flights
14
What is the problem?
Lack ofLack of pre-departure FPL updatesupdates can make the predicted flight trajectory invalid
PilotsPilots are sometimes not not informedinformed about changes to the FPL such as a new RFL and so cannot implement these changes
The vertical profileprofile or the route is not flownis not flown according to the FPL information held by the NMOC and ATC
15
Why does it make a difference?
Actual profileFPL profile
16
What is the effect?
ATC sectors are entered that are not on the flight profile described by FPL
The demanddemand ATC experiences can be significantly differentsignificantly different from what was expected - including over deliveries!
Lack of certainty about the real level of demand can lead ATC to apply sector capacity ‘buffers’capacity ‘buffers’
17
Why does it matter?
An independent study has estimated that improved predictability will provide the capability to increase sector monitoring values delivering:
an increase of 5-10%increase of 5-10% in local sector capacitiescapacities
a reductionreduction in delaysdelaysof 20-30 %20-30 %
Note that flexibility

remainsremains to deviate
from the FPL when
tactically necessary
18
How can aircraft operators and pilots help?
Update the FPL whenever “appropriate” Inform pilots about all changes to the FPL affecting
the conduct of the flight

Predictability issues, impact on ATCHow lack of predictability affects ANSP attempts to reduce need for regulation and may lead to safety issue.

and complexity)
DSNA is a path finder in Dynamic ATFCM process which allows a gain of capacity while maintaining high level of safety towards our customers.
BUT….

Our Objective: Safety, fluidity, efficiency, dynamicity, equity

Due to
Flight plan non adherence ETOT/CTOT non adherence AO reactivity when receiving a CTOT (even with 0’mn of
delay) Fancy routings
FMPs and ATC are daily facing unpredictable and dangerous situations.

Flight Plan is not just a flying ticket!
It should be mutual commitment and responsibility for safety and more

Results of SESAR Target Time (TT) Trials Validating an important step towards Time Based Operations

From CTOT to TT – Concept in a nutshell
Now: Use (only) CTOT for time-based ATFCM
Entry Time

Time-based ATFCM measure
• Assumed profile not always the actual profile• Objective of CTOT not managed after take-off• Actual trajectory and sector entry time can significantly
deviate from intended ATFCM measure
Issues:

Time-based ATFCM measure
Use Target Time at congestion
For trials:• Target Time +/- 3 minutes• Flight Crew aim to meet Target Times• Arrival Regulations => input to sequencing
Over-regulation or Over-delivery,
unpredictability
31
From CTOT to TT – Expected Benefits
For ALL Network actors: increase predictability More effective regulations Potential for capacity increase decrease of regulations
For airspace users: flexibility & flight efficiency Operational flight plan adapted to airline needs, meeting TT Effective regulations Better use of capacity Less holding, less ATC actions
(e.g. vectoring, separation,…)
For ATC (en-route/airports): potential local TT preferences exchange with NM Optimising local operations, based on local business rules
(e.g. arrival sequence, link to AMAN, XMAN)
In collaboration with Airspace Users
Potential drawbacks to be considered Workload for AO dispatch & pilots Impact on flight efficiency
32
From CTOT to TT – SESAR Validation Trials
Live trials using real airport regulations
TT Trial Palma June 2013 3 Airlines (Airberlin, EasyJet, Air Europa) 129 measured flights under TTA Validated also the integration of AOP and NOP:
TT optimised to respond to airport business needs
Fair Stream TT Trial May-October 2013 3 Airlines (Air France, Lufthansa, Swiss) CDG/DSNA - Munich/DFS - Zurich/Skyguide 800+ measured flights under TTA Validated preliminary AMAN integration at CDG
33
Validation Trials – Main Conclusions and further research
Ops procedures for TT sharing between NM/APT/AOC/Flight Crew:
Acceptable and applicable in real operational conditions
Network provided TT for airport regulations:
Can be used for airport impact assessment
And adjusted to optimise airport operations
Some lessons learned – Objectives for future trials Adherence to TT reduced by: DEP time fluctuation, Delta Plan/Execution,
ATC involvement Clear Predictability increase has been measured, but…overall network
impact & benefits to individual airlines still to be addressed (mid-2014)
Predictability at TTA fix not propagated to landing time predictability, reducing benefits for AO – May be solved by integration with AMAN
