What is PBN SAFER & BETTER FLIGHT EFFICIENCY 27.04.2017 PBN EUROCAE 7 Symposium
Main principles Route structure based on waypoints and independent from ground based navigation facilities (VOR, DME, NDB) Aircraft ability to maintain a path with a given accuracy => RNAV and provide an alarm when getting outside the limits => RNP Harmonised at ICAO level in PBN manual and translated into aircraft certification requirements and route design criteria 27.04.2017 PBN EUROCAE Symposium 8
Proposed PBN Regulation (EASA Opinion) Opinion En route En route Remains RNAV 5 TMA PCP 24 Major TMA/ADR SID/STAR must be: RNP 1 (plus addtl. function.) Opinion Other TMA/ADR SID/STAR may be: RNAV 1 or RNP 1 (plus addtl. function.) APCH Approach must be: RNP APCH with APV All NPA Rwys must be: RNP APCH with APV 27.04.2017 PBN EUROCAE Symposium 9

Enter PBN PBN improves Safety which tops any list. PBN s key benefits: Safety especially on Final Approach Flexibility where ATS routes, SIDs/STARs can be placed A great airspace planning/design tool if used correctly Interoperability one qualification, works everywhere; Better access to airports and airspace. PBN functions provide Confidence in navigation performance, both laterally and vertically, along a flight path (i.e. SID/STAR/IAP). Confidence is provided by PBN s ten RNAV and RNP specifications. These spell out crew and aircraft navigation performance needed to operate on a route. PBN Challenges and Solutions 25
PBN Challenges PBN Concept is Simple Application is Complex RNAV & RNP Terminology: Mix of Old/New and technical / operational Confused stakeholders Who needs to know what? Making PBN work for on the flight deck and for air traffic controllers Standardising 10 navigation specifications globally suggests one size fit all Is there a mandate? Let s have Mixed Mode and Let s have BEBS (Best-Equipped-Best-Served) No incentive to equip Rationalisation of Navaids difficult The Environmental Impact of PBN PBN Challenges and Solutions 26

The Environmental Impact of PBN Geoff Burtenshaw PBN Implementation Lead UK CAA
Argus News Thursday 27 February 2014 New Gatwick flight path trials are 'destroying' Sussex village life Good luck. I hope you are not planning to implement PBN below 10,000 feet or it could be 2028 not 2018 when it happens Wow! PBN has been so amazing. I am now not able to sleep at night and get no respite from aircraft noise even though my family and I were previously unaffected PBN is torturing lives NOW, if torture is the way of the future it s not a future I look forward too Residents around your PBN systemisation routes are not impressed. Want you to return to seat of the pants based navigation PBN Challenges and Solutions 36
UK Government Airspace Policy Framework Public Response to PBN and Aviation Noise UK Government Consultation February 2017: UK Airspace Policy July 2015 Airports Commission Recommendations CAA/Industry Noise Task Force Noise Mitigation Considerations when Designing PBN Departure and Arrival Procedures CAP 1378 Independent Commission on Civil Aviation Noise ICCAN) UK Airspace Policy: A Framework for Balanced Decisions on the Design and use of Airspace CAA Draft Airspace Design Guidance: CAP 1520 Air Navigation Guidance on Airspace and Noise Management and Environmental Objectives PBN Challenges and Solutions 37
UK Government Aviation Noise Policy Limit, and where possible, reduce the number of people significantly affected by aircraft noise Priority should be given to reducing significant impacts rather than the number of people who will experience some aircraft noise Explicit consideration of design options that compare single routes with multiple routes. The need to assess permanent and planned redistribution (PPR) of traffic Consideration of environmental factors from the outset via Design Principles and earlier community engagement Greater efforts at transparency and explaining noise impacts in meaningful terms PBN Challenges and Solutions 38
Example: Multiple PBN routes to disperse traffic below 7000ft (Relief options for PBN SIDs not constrained by NPRs below 4,000ft) Noise Objective: Relief, Concentration or Dispersal Environmental impacts Total number of people affected by noise New populations exposed to noise Intensity/frequency of aircraft experienced by those affected Noise Preferential Routes Fuel/ CO2 efficiency Operational impacts Runway Capacity ATC System capacity ATC system complexity Aircraft capability issues Fly-ability FMC capacity PBN Challenges and Solutions Applicability 39
Example: SID Alternation PBN Challenges and Solutions 40
Example: Multiple PBN routes to enable use of certain routes at certain times Noise Objective: Relief, Concentration or Dispersal CAP 1385: Noise Mitigation Considerations when Designing PBN Departure and Arrival Procedures http://www.caa.co.uk/commercial-industry/airspace/futureairspace-strategy/performance-based-navigation/ Environmental impacts Total number of people affected by noise New populations exposed to noise Intensity/frequency of aircraft experienced by those affected Noise Preferential Routes Fuel/ CO2 efficiency Operational impacts Runway Capacity ATC System capacity ATC system complexity Aircraft capability issues Fly-ability FMC capacity Applicability PBN Challenges and Solutions 41
Lufthansa SESAR AAL Trials AAL - Augmented Approaches to Land Curved approaches for the reduction of fuel and noise B748 Higher noise emission due to Configuration and higher thrust setting in turns! PBN Challenges and Solutions 42
Summary of the Environmental Challenges and Solutions Airspace change programme risks in the form of: Public consultation Cost Judicial review Hostility from local residents Local and national government politics All can have a serious impact on timescales for deployment One cannot overlook the potential downsides for the communities close to an airport from implementing PBN Environmental pressures: real risk to regulatory compliance including ICAO Assembly Resolution A37-11, SES Pilot Common Project, PBN-Implementing Regulation Challenge: take mitigation measures through airspace design to minimise the environmental impact on those communities PBN Challenges and Solutions 43
Summary of the Environmental Challenges and Solutions Area navigation techniques are part of the modern aircraft s DNA Seat of the pants navigation is over In theory: can design PBN routes to mitigate environmental (noise) impacts, but more work needed to assess actual level of respite/relief; New route designs May have environmental benefits, but create operational impacts & aircraft capability issues May also have dis-benefits local community perceptions are important It s not just a challenge to PBN The aircraft is the noise generator : Aircraft factors include: operating procedures, configuration changes, climb/descent profile, loading on departure and arrival routes, night-time noise etc. There will be no optimal solution that addresses all stakeholder needs but a balance will be required in order to find the most acceptable route positioning or operating concept PBN Challenges and Solutions 44

PBN Implementation, Implications and Opportunities John Dyson
Implementation RNAV 1 across London TMA 2020-2024 estimated RNAV 1 - Prestwick Lower airspace, - Scottish, Manchester, Birmingham TMAs and Irish Sea - from 2017 2020 Airport RNAV 1 SIDS and PBN approaches DVOR replacement programme 19 sites to 2020 DVOR & NDB rationalisation programme ongoing DME optimisation and replacement programme 48
Implications Over 100 ANSPs = co-ordination issues!! Delays to TMA implementation removing airport procedures from VORs (A/Ps own SIDS) NATS Policy to remove all en-route dependencies from DVOR / NDBs Costs and timescales of changing airports procedures Solutions / options for continued DVOR support site by site basis Airspace changes environmental challenge, consultation, reviews and costs Expectation for DFMC provide increased resilience to GNSS support of PBN 49
Opportunities Ground based equipment rationalisation (DVOR, NDB, DME, could also be Cat I ILS?) DME optimisation replacement / rationalisation / spectrum management - for DME/DME Co-ordinate Standards, regulations and implementation activities accuracy performance of modern DME Transponders can be taken into account Environmental capacity, fuel, parallel routings, noise, Safety - confidence in positioning accuracy Airspace re-design DME / DME currently independent back up to GNSS support of PBN 50
