    Executive Summary

    The global air travelling passenger traffic is anticipated to grow by 4.9%

    annually from 2011 to 2026. Meanwhile airfreight will rise 5.8% annually in the same

    period. IATA projected that the greatest demand will come from Asia Pacific region,

    where airlines will take delivery of 31% of new aeroplanes in the next 20 years.

    Singapore has developed a PBN implementation plan for Singapore FIR to meet this

    growing demand and also bring about other operational benefits.

    As the skies get busier with more aeroplanes, PBN will serve to increase

    airspace safety, capacity and efficiency. Flight times will also be reduced with optimal

    flight paths design using PBN specifications resulting in fuel saving and enhanced

    environmental protection.

    Singapore has been implementing PBN procedures in a steady and progressive

    manner. The Plan adopts a 3-phase approach: Short Term (2008-2012), Medium

    Term (2013-2017) and Long Term (beyond 2018).

    With full support of and close collaboration with the stakeholders in Singapore

    consisting of local airlines, ANSP, regulators and engineers, Singapore plans to

    address the impact of air traffic growth by increasing capacity and efficiency while

    simultaneously improving safety and reducing environmental impacts. To achieve its

    goals, Singapore is implementing new Performance-Based Navigation (PBN) routes

    and procedures that leverage emerging technologies and aircraft navigation

    capabilities.

    Chapter 1 Overview

    1.1 Background

    1.1.1 The Singapore Flight Information Region (FIR) shares boundaries with five

    other neighbouring FIRs; namely Ho Chi Minh, Jakarta, Kota Kinabalu, Kuala Lumpur

    and Manila FIRs. The airspace within the Singapore FIR is largely over the high seas

    and as such, widespread siting of ground navigational aids is not possible.

    1.1.2 Within the airspace around Singapore, high density air traffic movement

    consisting of international and regional flights into and out of Changi Airport and other

    airfields within a 40NM radius makes air traffic management a challenge.

  • 1.2 Purpose

    1.2.1 This PBN Implementation Plan is published to provide a roadmap for

    implementation of the ICAO PBN Concept in the Singapore FIR. PBN procedures

    would be implemented in a steady and progressive manner through a 3-phase

    approach (short, medium and long term).

    1.3 Strategic Objectives

    1.3.1 With the application of the ICAO PBN Concept, Singapore aims to achieve the

    following objectives:

    a) Enhance Efficiency

    Enhanced reliability, repeatability, and predictability of operations to

    increase air traffic throughput and smoother traffic flow. RNAV

    departures result in better climb profiles to optimum en-route altitudes

    thus reducing fuel burn, and reduced track distances. RNAV arrivals

    result in continuously descending path with minimum level flight

    segments to enable smooth aircraft deceleration and configuration

    prior to landing.

    b) Enhance Capacity

    Delays, congestion, and choke points at airports and in crowded

    airspace may be reduced because of new and parallel offset routes

    through terminal airspace, additional ingress/egress points around

    busy terminal areas, more closely spaced procedures for better use

    of airspace, and reduced or eliminated conflict in adjacent airport

    flows.

    c) Enhance Safety

    Lateral and vertical track-keeping is much more accurate and reliable

    due to new three dimensional guided arrival, approach, and

    departure procedures that cannot be defined by conventional

    navigational aids. PBN also reduces the flight crews exposure to

    operational errors.

    d) Reduce Environmental Impact:

    Utilize PBN to reduce environmental impact from aviation through

    more efficient operations that result in a less fuel burn and noise

    emissions. Flying down the middle of a defined flight path means less

    throttle activity and better avoidance of noise-sensitive areas, so

    people on the ground perceive less jet noise and are exposed to

    fewer engine emissions.

    Chapter 2 Performance-based Navigation (PBN)

    2.1 PBN Concept

    2.1.1 The PBN Concept is based on a shift from sensor-based navigation to

    performance based. The PBN concept specifies that aircraft area navigation system

    performance is defined in terms of accuracy, integrity, continuity and functionality. It

    explains and describes the performance-based RNAV and RNP navigation

    specifications that can be applied to oceanic, en-route and terminal airspace, to

    improve safety, efficiency and capacity, as well as reduce the environmental impact.

    These specifications also detail the navigation sensors and equipment necessary to

    meet the performance requirement.

    2.1.2 The application of a PBN specification depends on many factors the

    navigation infrastructure, communications capability, surveillance capability, the

    operational requirement, the aircraft fleet capability and operational approvals etc. In

    determining which PBN specification to apply, these factors must be taken into

    consideration in consultation with all stakeholders.

    2.1.3 For Singapore, the application of the PBN concept is important mainly to

    enhance airspace safety, capacity and efficiency.

    2.2 Current Implementation Status

    2.2.1 Oceanic, Remote and Continental En-route

    2.2.1.1 RNAV en-route operations in the South China Sea area based on

    RNP10 requirements began as early as November 2001. The six major routes

    connecting Singapore and the airports in North-east Asia were arranged in a parallel

    route structure. Back then, the States involved had agreed on a 60NM lateral and

    80NM longitudinal separation based on Mach Number Technique as the standard

    separation minima for the RNP10 routes.

    2.2.1.2 In July 2008, reduced horizontal separation down to 50NM lateral / 50NM

    longitudinal based on RNAV10 operation was implemented on two routes, M771 and

    L642, which catered for the high air traffic flows between Singapore and Hong Kong

    as well as the airports in China. A quick glance on the four remaining parallel routes

    in Singapore FIR suggests RNAV10 as the de-facto standard operations to pursue for

    these routes as well.

  • 2.2.1.3 In February 2012, restructuring of ATS routes in the south-east portion

    of Singapore FIR for flights to Jakarta FIR and beyond to Australasia region enabled

    two routes, M635 and M774, to employ reduced horizontal separation down to 50NM

    lateral / 50NM longitudinal based on RNAV10 operation.

    2.2.1.4 In August 2012, two RNAV5 routes, M630 and Y339, were established

    to enhance air tra
