Implementation process: Overview This presentation aims to provide a guidance on the RNP APCH implementation process to the States and ANSPs as the natural leaders of such activities but also to all the stakeholders concerned by RNP APCH. This presentation is based on: The most recent ICAO PBN implementation methodology included in Doc 9613- the PBN Manual The applicable and available ICAO, EASA and EUROCONTROL documents Lessons learned from pioneer implementation projects Implementation Methodology: Process 1 Deciding what to implement and where Process 2 Validation of assumptions and expectations and the implementation itself
Implementation process: Overview Key aspects for a successful implementation of RNP APRCH 1. Team must include all stakeholders 2. Reasons for implementing RNP APCH 3. Define a realistic and reachable project plan 4. Start with one procedure in one easy airport and focus all efforts on it 5. Flexibility to introduce modifications as project evolves 6. Keep informed to the extended team about the project evolution
Implementation process: Overview Process 1 Deciding what to implement and where Process 2 Validation of assumptions and expectations and the implementation itself Decision Analiseand Plan Design & Implementation
Implementation process: Decision (detailed) Background of RNP APCH Implementation Create Implementation Project Team Agree project objectives, scope and timescale
Implementation process: Decision (detailed) Background of RNP APCH Implementation 1. ICAO Assembly Resolutions A36-23 and A37-11 2. Strategic objectives Better airport accessibility Improve safety (better situational awareness + estabilisedapp.) 3. Airport operator requests 4. PBN Implementation plan 5. Environmental policy directives
Implementation process: Decision (detailed) Create implementation Project Team
Implementation process: Decision (detailed) Agree project objectives, scope and timescale 1. Once the implementation team has been established it needs to define the objectives, scope and resources for the team to build the implementation plan 2. Priority should be put into enabling the first implementation in order to gain the necessary experience
Implementation process: Analise and Plan Survey of candidate airports Evaluation of airport capabilities CNS/ATM considerations Survey of aircraft operators Business Case
Implementation process: Analise and Plan Survey of candidate airports 1. According to Assembly resolution A37-11, RNP APCH should be implemented to all instrument runway ends serving aircraft with a maximum certificated take-off mass of 5 700 kg or more 2. As a first step, one or two candidate airports can be identified to be the first implementation locations 3. Implementation at non-instrument runway ends is not currently envisaged by the international standards. First implementations should therefore take place at runways that already have an instrument approach procedure.
Implementation process: Analise and Plan Evaluation of airport capabilities 1. Aerodrome infrastructure assessment 2. Meteo data 3. GNSS Infraestructure 4. Other Infraestructure 5. Achievable minima estimation 6. Integration of the new procedure into de terminal area
Implementation process: Analise and Plan Evaluation of airport capabilities Altitude Latitude, Longitude Orientation True axis Threshold characteri stics MET Tool Category Main sizes Aircraft dimension s LNAV LNAV / VNAV LP LPV ILS Approach Option MET - OCH/OCA - Critical obstacle - Surface s planes Local (x,y) geographic coordinates Altitude or height Airport s obstacles It allows a rapid assessment of the straight-in final approach and the initial and intermediate missed approach segments
Implementation process: Analise and Plan Survey of aircraft operators 1. Not all RNP APCH types are of interest of all categories of airspace users. In general terms: Baro-VNAV is the preferred option of Commercial Air Transport SBAS is the preferred option for Regional operators and general aviation 2. Information should be collected regarding the following: Aircraft equipment and navigation capabilities Airworthiness and operational approval Current experience with RNP APCH procedures Operator requirements and preferences for RNP APCH procedures Plans in terms of future equipage and operational approval
Implementation process: Analise and Plan Business Case The BC can address the costs for ANSPs and/or airports or the costs for aircraft operators Costs for ANSPs/Airports Costs for aircraft operators Procedure design Equipment acquisition Flight validation Safety assessment RWY upgrades Equipment installation Airworthiness and operational approval Crew training Others: training, approval
Implementation process: Analise and Plan Business Case Airport-oriented BC overview Purpose: to make a comparison between the RNP APCH implementation costs and the benefits derived from quantifiable operational improvements The main quantifiable operational improvements from APV are those associated with avoidance of delays and diversions thanks to: Reduced operational minima Back-up alternative to ILS GNSS based APV procedures are also beneficial in terms of: No reliance on ground navaid infrastructure Environmental benefits More landing fees More handling fees More PAX fees Less disrupted operations means a higher number of landings for the airport
Implementation process: Analise and Plan Business Case 1 2 3 4 5 6 Airport-oriented BC in detail Review of total aircraft landings Review of non-ils aircraft landings Disruption probability per approach type Aircraft NPA disruptions Reduction in disruptions Total benefits in airport fees
Implementation process: Analise and Plan Business Case Airport-oriented BC in detail Number of landings per year Traffic prevision for the next 5 years Number of landings per category per year % Cat A % Cat B % Cat C % Cat D Non-ILS aircraft landings per category per year
Implementation process: Analise and Plan Business Case Airport-oriented BC in detail The main quantifiable benefit of APV is reducing diversion when: ILS is unavailable for landings(maintenance) Weather conditions affect landings in a NPA THR ForNPAlandings,itisconsideredthatdisruptionsmaybecausedby: Poor runway visibility (M)DA/DH Low cloud ceiling NPAlandingsarenotpossibleif: Recorded Cloud Ceiling <(M),DH Recorded Visibility(km) < RVR Required visibility Recorded visibility Required cloud ceiling Recorded cloud ceiling Threshold (50ft) Runway
Implementation process: Analise and Plan Business Case Airport-oriented BC in detail The reduced number of disruptions with regards to NPA landings will be considered as a percentage of gain in operations due to APV SBAS landings The monetary conversion of operation gain is based on landing charges and consequent additional airport incoming fees
Implementation process: Analise and Plan Business Case Operator-oriented BC in detail Purpose: to make a comparison between the a/c (or fleet) retrofitting costs and the benefits derived from quantifiable operational improvements The main quantifiable operational improvements from APV are those associated with avoidance of delays and diversions thanks to: Improved airport s accessibility thanks to reduced operational minima Back-up alternative to ILS For operators, less diversions mean less fuel consumption
Implementation process: Analise and Plan Business Case Operator-oriented BC in detail 1 2 3 4 5 6 Total costs derived from a/c retrofit Review of non-ils aircraft landings Disruption probability per approach type Aircraft NPA disruptions Reduction in disruptions Total benefits due to this reduction
Implementation process: Analise and Plan Business Case Operator-oriented BC in detail Possible costs to be avoided: Diversion(fuel) Destination Airport A Alternate Airport B PAX transportand others
Implementation process: Analise and Plan Business Case Examples of results of BC regarding RNP APCH: International Airport: Benefits after 4 or 3 years (depending on pessimistic or optimistic case) Mediterranean small airports (two): APV implementation is cheaper than ILS and it has similar performance, so it s the recommended option. Regional operator: For a fleet of 63 aircrafts, the benefits of APVsgiveanetbenefitof 9Min10years General Aviation operator: Pay back for upgrading the fleet is 5years
