Agenda
› LSZH SID with RF leg
› LSZC RNP APCH to
LNAV in mountainous
terrain
3
LSZH RNAV SID 34: Goals
› Trial to gain experience for future RF leg applications.
› Collect data to be used for future design RF leg procedures.
› Minimize noise (reduction of flight tracks distribution in turn).
4
RF SID VEBIT 1K LSZH RWY 34
› Overlay to existing SID, but different SID designator
› Low traffic numbers on DEP 34
› RNAV 1, GNSS only
› RF leg on first turn
› Narrow radius: 2.1 NM
› Implementation:
18 OCT 2012
5
Monitoring: Flight tracks 18 OCT to 29 AUG 2013
RF SID: 1224 flights Non RF SID: 679 flights:

Monitoring: Track deviation RF SID
Noise monitoring: Overflight densitiy

According PANS-OPS @ IAS 210 kt:
Wind 0 kt: 20.8°
Wind 30 kt: 25°
Wind 36 kt: 26.8°
RF SID: Lessons learnt
› Good track performance, robust procedure
› Concentration of noise
› 65% of SID 34 DEP at LSZH able to fly RF legs
› Only RF leg-capable aircraft get RF SID packed in FMS database
› RF leg capability not part of FPL 2012, increased R/T

LSZC RNP APCH to LNAV: Goals
› Cloud break procedure for Pilatus Aircraft Ltd
› Use of RNAV approach for test flights
› Use initially limited to pilots operating for Pilatus Aircraft Ltd
Final Approach LNAV

VMC part
› Non straight-in followed by a VMC part
› Chart title: RNAV (GNSS) A
› Aeronautical study to address flight
OPS risks
› Special pilot qualification required
› MDA initially 3500 ft,
VIS 3000 m, day only
› Implementation foreseen for 14 NOV 2013
