ENV01 (ppt) - Eurocontrol

Objective ENV01
ESSIP Plan 2014
Bernd HILL
 The objective aims at implementing Continuous Descent
Operations (CDO1) techniques that will produce a number of
environmental and cost benefits including reductions to fuel burn,
gaseous emissions and noise impact.
 FOC: 12/2013
ICAO uses Continuous Descent Operations (CDO) and replaced the Term
Continuous Descent Approach (CDA) with Publication of ICAO Document
ESSIP Plan 2014 / Objective ENV01
What has changed since LSSIP 2013 ?
 The Term CDO replaced the Term CDA in the text
 The following additional Note was added:
Note 2: In principle, it is not required to implement CDO on a 24/7 basis,
but is preferable, where applicable. Depending on National legislation
and/or National court decisions and/or local constraints at airports, a
limited introduction, for example during night time, is considered equally
 ICAO Doc 9931 - Continuous Descent Operations Manual, Edition 1,
dated 31.12.2010 was added as supporting material for the
implementation of this Objective.

 OI step - [AOM-0701]- Continuous Descent Approach (CDA)
 Description:
When applied at an airport, CDA would offer a flexible and simple
continuous descent approach technique that does not adversely
affect safety and capacity and will produce a number of
environmental and cost benefits including reductions to fuel burn,
gaseous emissions and noise impact.
 IOC: 07/2007
 FOC: 12/2013
Most important SLoA(s)
 To cater for Successful implementation of CDO at designated airport
 If procedures are not published, do not report progress “Completed”
 “Completed” if all approach Controllers at airport are suitably trained
and make use of CDO
 To cater for AOP role in implementation: Support CDO measures,
implement monitoring of performance and feedback to ANSP and
users where equipment is available. Provide the main link with the
local community
Finalisation Criteria and Closed Questions (1)
 If CDO is implemented, please confirm the period for which you offer
CDO to pilots:
e.g. Night time only / Day-time only / 24/7 hours/ as traffic density
allows / Majority of flights offered a CDO during period of x.
 If CDO is implemented, what % of total airport approaches
(approximatively) are achieving a CDO profile?
Select one among 0-20% / 20-40% / 40-60% / 60-80% / 80-100% or
provide any more precise figure
Finalisation Criteria and Closed Questions (2)
ENV01-APO 01
 If CDO is implemented, please indicate whether the monitoring
results are being regularly reported to all Stakeholders involved:
and if Y (above) please indicate which type of results (e.g. fuel
consumption, noise, emissions)?
Note: Monitoring of performance is not compulsory for SLoA Status
“Completed”, but is recommended for best practice.
 If CDO is implemented, what % of Airlines are being active at your
airport in applying CDO?
Indicate the % of Airlines applying and using CDO
Objective’s completion criteria
 Partially completed:
At least, either a CDO design has been approved or a CDO trial has
 Completed:
CDO is established as an operational procedure and procedures are
formally published and used in practice. A working arrangement to
track performance and seek improvement has been established.
ESSIP Report 2013 – Interim Deployment Programme
 IDP View:
From the Airspace Users perspective on CDO implementation it is
clear that there is no real CDA when aircraft is vectored, as real
CDA needs closed-loop routing.
In addition, from Airspace Users viewpoint it would be more
appropriate to measure the level of CDO implementation by
measuring the percentage of time when the pilot performed the
CDO procedure vs total number of approaches.
This is because there are many cases where CDO procedures
are published but not used during a whole 24h period.
Objective Coordinator’s Analysis
 States should verify that CDO procedures have been published and
are in practical use before declaring the objective as ”Completed”.
