Now
– GLS (GBAS)
– GLS TAP (GBAS)
Now
In Trial
• Airbus & Boeing are committed to RNP RNAV 0.1 (or less) and GLS
– FMS changes complete or planned for most models
– LPV not in current plans at Boeing or Airbus
• Embraer and Honeywell are developing similar strategic roadmaps
– RNP 0.1 in development for Epic platforms

GBAS Benefits
• For Airports:
– Lower Installation and Maintenance Cost Than ILS
- One GBAS enables Cat I Capability at all Runway Ends
– Supports Noise Abatement
- By enabling precision departure and offering multiple departure paths
– Unlocks Airport Real Estate
- Eliminates hold-short zones for greater tarmac capacity
• For CAAC/ATMB:
– Improves Or Preserves Airspace And Airport Capacity
- Enables multiple new operations
• For Airlines:
– Critical Enabler for Fully Automated Landing
– Improves Operational Assurance
- Guaranteed Landing In Adverse Weather Saves Cost of Diversion
– Reduces Fuel Burn And Emissions
• For All:
