Required Navigation Performance (PBN)

RNP and RNP-AR Approach and Departures including One Engine In-Operative application

Global Airspace Solutions Chief Designer has a strong background in Required Navigational Performance – Authorisation Required (RNP-AR) Procedure Design.

There are many benefits of RNP / PBN operations:

Improving Safety   

  • Reduces the risk of Controlled Flight Into Terrain (CFIT) accidents
  • Provides very precise lateral and vertical flight paths
  • Provides consistent, predictable and stabilized approaches
  • Aircraft arrive at the runway aligned with the centreline: same configuration & same speed every time.
  • Reduces diversions caused by adverse weather conditions
  • Enables aircraft to reliably access airports with lower visibility restrictions

Improving Operating Returns   

  • Reduces fuel waste through shorter flight tracks optimized profile descents and fewer diversions
  • Enables more direct and closely spaced parallel tracks enroute for increased fuel efficiency and reduced flight time variance
  • Creates new market opportunities by providing safe access to terrain and weather challenged destinations
  • Provides a path for airline growth as emissions caps are implemented around the world
  • Provides a degree of precision approach capability without the investment required for expensive ground-based infrastructure

Increasing Airspace Capacity  

  • Increases traffic capacity through more efficient routes and smoother flows
  • Reduces airspace conflicts between adjacent airports and prohibited or special use airspace

 

 

Environmentally-Friendly   

  • Reduces emissions by saving fuel
  • 3.19 kg of CO2 emissions are eliminated for every kg of fuel saved
  • Achieved via shorter/vertically optimized PBN flight paths
  • IATA’s estimations indicate shorter PBN routes globally could cut CO2 emissions by 13 million tonnes per year
  • Provides a mechanism for optimized profile descents
  • Allows aircraft to descend from high altitudes to airports at minimum thrust settings
  • Consistent, precise paths can be routed to avoid noise sensitive areas
  • Noise levels can be reduced via use of optimized profile descents
  • Allows lower, quieter thrust levels
