What is RNP?First, lets look at a traditional
approach to an airport...
The vast majority of instrument approaches in the
world today are flown according to this design
philosophy. This is well-established and very
safe, but is near its maximum capability in terms
of efficiency, carbon emissions, and capacity.

What is RNP?Now lets look at an RNP approach
procedure
Satellite-basednavigation (GPS)
Fly within containment corridor
EngineThrust
EngineThrust

RNP requires more capability with the pilot,
airplane, and ATC(including training, equipage)
EngineThrust
Greater design flexibility
EngineThrust
Curved paths, stablized continuous descent
(engine idle)

Some RNP Benefits
  • Safety
  • Stabile approaches
  • Protection in engine-out emergencies
  • Operational consistency
  • Reduced risk of controlled flight into terrain
  • Environment Capacity
  • Emissions reductions
  • Noise reductions
  • More air traffic/airport capacity
  • Financial
  • Fuel savings
  • Aircraft utilization
  • Reduced engine wear
  • Cap Trade
