SUBJECT: : Implementation of RNAV non-precision instrument approach procedures based on GNSS.
The French Administration has published, since the end of 2004, RNAV non precision instrument approach procedures based on the current Global
Navigation Satellite System (GNSS).
The purpose of this Aeronautical Information Circular is to inform of new provisions concerning the design and use of RNAV/GNSS procedures by
French and foreign operators. These changes notably relate to missed approaches proce¬dures.
2 REFERENCE DOCUMENTS
Reference documents are:
Operational directive DCS F-2007-01 dated April 2007, 26'h, referring to non precision approach procedures based on RNAV/GNSS instruments,
available on
http://www.aviation-civile.gouv.fr/html/prospace/pilots_exploitants/consignes_op/consignes.htm. It replaces operational directive F-2005-01.
« AMC 20XX V2-6 AIRWORTHINESS APPROVAL AND OPERATIONAL CRITERIA FOR RNP APPROACH OPERATIONS Draft- Version 2.6, 21
December 2006 » which replaces the « DGAC Interim Guidance for Airworthiness and Operational Approval of RNAV System for RNAV/GNSS
Approach (T and Y approaches) (Issue 1, date 01/01/2004) ».
AIC 01/06 published 2d of February 2006 on GNSS NOTAM that can be used for preflight planning purposes (available on https://www.sia.aviationcivile.gouv.fr/dossier/aicom/AICA_CAR_2006%2001B_EN.pdf.
Most important information was synthesized in the guide for non precision approaches operations based on RNAV/GNSS equipment, available on
the AIS website. It must be noted though its content does not include provisions for missed approach procedures newly mentioned in the present
aeronautical information circular.
3 CERTIFICATION OF ON-BOARD SYSTEMS
Aircraft must be equipped with a GNSS receiver approved for instrument approach procedures in order to perform RNAV/GNSS approaches. This
receiver can be either stand-alone or integrated to a multi-sensor navigation system (e.g. FMS).
Systems including GNSS/SBAS sensors are eligible for RNAV/GNSS procedures.
Approval of the system will follow the classical certification process.
Applicable standards are described in the document « AMC 20XX_V2-6 AIRWORTHINESS APPROVAL AND OPERA¬TIONAL CRITERIA FOR
RNP APPROACH OPERATIONS Draft- Version 2.6, 21 December 2006 » mentioned in §2. Certification of aircraft complying with the document «
DGAC Interim Guidance for Airworthiness and Operational Approval of RNAV System for RNAV/GNSS Approach (T and Y approaches) (Issue 1,
date 01/01/2004) » and already operating RNAV/GNSS non precision approach procedures, will not be reviewed.
4 SELECTION OF AERODROMES AT THE FLIGHT PLANNING
A RNAV/GNSS non precision approach can be selected at the destination aerodrome.
If the operational regulation does not require a destination alternate, at least one conventional approach (non RNAV/GNSS) procedure must be available
at the destination aerodrome.
If the operational regulation requires at least one destination alternate, one conventional approach procedure (non RNAV/GNSS) must be available
at the destination alternate aerodromes.

AIC N° 01/09
A non precision RNAV/GNSS approach procedure cannot be selected:
- At the aerodrome of departure if it is planned to return in case of failure;
- For the purpose of selecting a take-off alternate aerodrome.
5 NEW PROVISIONS FOR MISSED APPROACH PROCEDURES
5.1 Missed approach :
The missed approach segment is based upon either area navigation (RNAV/GNSS), dead reckoning or conventional navaids (e.g. VOR, NDB).
5.1.1 Missed approach based on RNAV
Use of the RNAV system during the missed approach is acceptable provided the RNAV system is operative (e.g. no loss of function, no RAIM alert
or loss, no failure indication...) and the whole procedure is loaded from the navigation data¬base.
If the approach must be discontinued for a reason independent of the RNAV/GNSS system operation (e.g. no visual ref¬erences when reaching the
minima, excessive flight technical error), the flight crew shall keep on using the RNAV/GNSS guidance to perform the missed approach.
In case the approach must be discontinued because of a failure or loss of the RNAV/GNSS navigation system, the oper¬ator must define and perform
a contingency procedure (followed by a joining phase). It consists in reaching a safe alti¬tude along a free of obstacles flight path. Existing obstacles,
aircraft performance and onboard system characteristics shall be taken into consideration.
The joining phase, meant to allow operate a new RNAV/GNSS approach or any other type of approach, shall be based on conventional means and/or
rely on radar assistance.
5.1.2 Non RNAV missed approach
If the missed approach segment is based on conventional means or dead reckoning and the procedure must be dis¬continued for a reason independent
of the RNAV/GNSS system operation, flight crew may use the RNAV/GNSS guid¬ance to perform the missed approach, according to requirements
of the operational directive.
6 PHRASEOLOGY
Pilot and controller basic phraseology.
When GNSS approach clearance is requested by the pilot once he has checked it can be carried out. Pilot and controller basic phraseology:
� Lille, Citron Air 32 45, demandons approche G_N_S_S piste 0 8.
☺ Citron Air 32 45, autorisé approche G_N_S_S piste 0 8
� Lille, Citron Air 3 2 4 5 requesting G_N_S_S approach runway 0 8.
☺ Citron Air 3 2 4 5 cleared G_N_S_S approach runway 0 8
When GNSS approach clearance has been given by the controller and in case the approach has been initiated and must be discontinued:
� Lille, Citron Air 32 45, approche G_N_S_S piste 0 8 impossible, demandons approche ILS.
☺ Lille, Citron Air 3 2 4 5 unable G_N_S_S approach runway 0 8, requesting ILS approach.
