Controlled Flight Into Terrain (CFIT):
• responsible for 37% fatal accidents (2011 – 2015)
• Most occur in approach/landing phases
• Often associated with loss of situational awareness
IATA Safety Report 2015
Regional operations:
• > 3450 airports
• 82% visual approach only (*) (*) one major ATR operator in Asia

PBN’s rationale
Improve Safety
Enhance Navigation
Optimize Air Traffic
Increase Airport Accessibility

RNP AR Complex 3D profiles
LNAV turns VFR into IFR
