Re-inforce the GNSS approaches with vertical barometric guidance (APV Baro-VNAV)
Introduce RNP Approaches with Authorisation for specific gains
Business Jets
Area navigation path supporting increased airport accessibility, safety and highperformances.
Supports GNSS approaches with GNSS vertical guidance (APV SBAS)
Helicopters
Supports GNSS approaches with APV SBAS,
Medical Evacuation
RNAV 1 arrival/departures

RNAV 1 DSNA strategy
Since 2008, most new RNAV applications in TMA are supported by
RNAV1
End 2010, 17 RNAV 1 studies launched, 7 RNAV 1 publications
Progressive shift from existing TMA B-RNAV + to RNAV 1
RNAV 1 supports current CDA experimentations
– Paris, Toulouse, Strasbourg,…
Main hurdles
– Migration to RNAV 1 launched on a case by case basis, when local ATC
dispositions are reviewed
– Lack of a mandate for aircraft equipage, slow migration in TMAs where the ATC
cannot handle a diversity of users without compromising efficiency.
Some new RNAV applications supported by RNAV 5
To include more users within the application
– Ex: Nice high altitude arrivals

RNP APCH DSNA strategy (1/2)
Final target is full compliance with 37th Assembly resolution (2016)
Initial implementation is LNAV
End 2010, 115 RNP APCH with LNAV minima studies launched, 50
have reached publication
– Close to Assembly 37, resolution A36/1, objective of 30% of runway ends by
2010
No specific hurdle identified for LNAV
9
RNP APCH DSNA strategy (1/2)
All RNP APCH approach will support LPV minima:
End 2010, 22 RNP APCH with LPV minima studies launched, 1 has
reached publication (see hurdles)
Main hurdles for LPV
– Delay in EGNOS SoL declaration
– Limited user equipment (AMC 20-28 expected ASAP)
RNP APCH with LPV minima expected to replace some ILS Cat I
France has a large number of ILS Cat I
DSNA strategy is: ILS Cat I not replaced since 2010 on smaller airfields
2015 Strategy fo larger airfields to be reviewed next year

VOR/DME: 500 ft

Cat C: 280 ft

12
RNP APCH DSNA strategy (2/2)
RNP APCH with BaroVNAV vertical guidance (LNAV/VNAV minima)
implemented in coordination with airspace users:
Implementation coordinated with Air France (priority list of 28 runways)
End 2010, 1 RNP APCH with LNAV/VNAV minima studies launched, 0 has
reached publication (see hurdles)
– Brest will be the first RNP APCH published (2011) with three minima line
– LNAV (370 ft), LNAV/VNAV (370 ft), LPV (250 ft or 300 ft depending runway
classification)
Main hurdles for LNAV/VNAV
– Lack of finalized safety case (Eurocontrol)
– Depending on mitigation of QNH errors, specific ATC/Aircrew phraseology to be
defined
– Users already equiped not yet qualified vs. AMC 20-27
13
RNP APCH user forum
DGAC organizes three times a year meetings with major industrial partners
and DGAC key experts to discuss APV EGNOS implementation :
Airbus France (A 350 LPV certification)
Airbus Transport International (ATI) operating Beluga
Dassault Aviation (cockpit EASy II certification)
Eurocopter
Thales Avionics
Eurocontrol
ESSP
For APV Baro VNAV, a DGAC working group has been setup with one
major airline participation
Air France
14
RNP APCH European projects
DSNA participates to:
Beluga project sponsored by Eurocontrol to equip and certify one Beluga
Aircraft with LPV capability (AMC 20-28) and to publish one LPV procedure
– Beluga Certification expected 1st half 2011, using Pau LPV procedure
Accepta project, partially sponsored by GSA (FP7) with the objective to
publish 3 LPV in France.

ICAO phraeology seems not fully complete to handle all of these cases, including
specific BaroVNAV mitigations required by the Eurocontrol Safety case
Coordination at ICAO level required to support full RNP APCH implementation
17
Conclusions
A lot of operational experience has been collected through the deployment of RNAV 1 and RNP APCH in France
Now documented within an exhaustive DSNA PBN course
Devoted to RNAV 1 and RNP APCH implementation
Used for the initial and on site formation of DSNA operational staff (ATC, etc..)
ICAO material supporting APV implementation is exhaustive, and has been used by France
– Complement to be made to phraseology? Charting?
– Existing ICAO approach classification, including APV, is sound and not expected to change
Completion of Eurocontrol APV generic safety cases now required
DSNA has now developped exhaustive safety material for all other PBN applications
Completion of EASA AMC 20 27 and 20 28 now required
PBN plan for France publication expected 2011
