Agenda
› LSZH SID with RF leg
› LSZC RNP APCH to
LNAV in mountainous
terrain

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

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
