• Turns allowed: 2-358°
• Spiral splay for joining different semi-widths
• OIS height calculation: d based on arc length with smaller radius (r – 186m)
• Turns before achieving 90m MOC

Charting Issues
• 30 Nov 2022 RNAV(GNSS) & RNAV(RNP) -> RNP • PBN requirements box to include
– Nav specification – Nav requirements
• Chart designation to include suffix for: – LPV only – LNAV/VNAV only – LPV, LNAV/VNAV only –
LP only – AR
• Variable RNP accuracy requirements charted by notes
