Çanakkale VOR procedure (source: DHMI) Çanakkale LPV procedure (source: Pildo Labs) 10 Design of LPV in Çanakkale (VI) CURRENT PUBLISHED NPA (VOR) PROCEDUREPROPOSED LPV APPROACH PROCEDURE  Compared to current NPA published procedures in Çanakkale, LPV offers:  Vertical guidance allowing continuous descent profile —Benefits in terms of engine noise and pollution  Reduction in the operational minima of more than 900 ft (~270 metres)  Independence from ground navaids

11 METIS Workshop Benefits of EGNOS in Civil Aviation, Istanbul 18 November 2009 Database coding process  LPV procedure is defined by a Final Approach Segment Data Block (FAS DB) with a Channel Number identifier:  The FAS DB is a set of parameters to identify a single LPV during the coding and define its associated approach path (including a CRC reminder)  The Channel Number consists on 5 numeric characters in the range to to identify an individual approach during operation  This data is provided to database coders (Jeppesen) to insert it in their systems  Receiver manufacturers (Garmin) build the receiver’s database

12 METIS Workshop Benefits of EGNOS in Civil Aviation, Istanbul 18 November 2009 GNSS receivers and platform operation (I)  Garmin GNS480: certified avionics receiver computing deviations for pilots  Septentrio PolaRx2: lab receiver for system monitoring

13 METIS Workshop Benefits of EGNOS in Civil Aviation, Istanbul 18 November 2009 GNSS receivers and platform operation (II)  Deviations computed by the GNS480 – horizontal only  Presented to the pilot thanks to a CDI/VDI (Course Deviation Indicator/Vertical Deviation Indicator) OPERATION DURING INITIAL APPROACH (IAF to IF) CDI/VDI GNS 480 GNS 480 in TERMINAL mode Glide Slope Flag OFF

14 METIS Workshop Benefits of EGNOS in Civil Aviation, Istanbul 18 November 2009 GNSS receivers and platform operation (III)  Deviations computed by the GNS480 – horizontal & vertical  Presented to the pilot thanks to a CDI/VDI (Course Deviation Indicator/Vertical Deviation Indicator) GNS 480 CDI/VDI OPERATION IN LPV MODE (IF/FAF to Destination) GNS 480 in APPROACH mode LPV annunciator Glide Slope flag ON

15 METIS Workshop Benefits of EGNOS in Civil Aviation, Istanbul 18 November 2009 Results and Lessons Learnt from the trials at Çanakkale (I)  Heritages from previous EU projects (Valencia, San Sebastian, Nice, Sion, Clermont-Ferrand...) re-used and adapted for this location  1 st day: 5 th November 2009  Intermittent LPV (APV 1) service in the area (edge of EGNOS coverage)  All attempts ending with an ‘Abort Approach’ message in the receiver’s display  2 nd day: 6 th November 2009  Nice performance of EGNOS SIS  5 approaches flown successfully

16 METIS Workshop Benefits of EGNOS in Civil Aviation, Istanbul 18 November 2009 Results and Lessons Learnt from the trials at Çanakkale (II)  1 st day: 5 th November 2009  Intermittent LPV (APV 1) service in the area  All attempts ending with an ‘Abort Approach’ message in the receiver’s display Example: 1st Approach HPL > HAL = 40m LATITUDE LONGITUDE Approaches aborted, not downgraded, due to the lack of LNAV minima in the chart
