Introduction

 God gave Egypt unique place center

• f the world.

 For that we redesign our air space to

put Egypt in stature worthily of the name of Egypt and back to be the leader of Middle East Region.

 We are going to follow the future of

aviation and apply what we must do.

 We have transparency with our

selves we are looking for support from GNSS bodies and that we are expected from this workshop and determined what is requirements to us to use SBAS for Air Traffic Control Service.

Egyptian Air Space Strategy

 The future air space strategy (FAS) is

designed to ensure the Egyptian air space provides:

 Sufficient capacity to meet forecast

demands whilst minimizing environmental impact by allowing flight profiles closer to optimum, this will be achieved principally by adding the Egyptian air traffic management

 ATM system to establish an enduring

and resilient structure

 That will greatly reduce the number

• f potential conflicts between air

space users.

 Allow aircraft to fly more direct routes

greatly improve the efficiency of departure & arrivals in particulars terminal airspace and use smarter

 More joined up traffic management.  Techniques to optimize airspace

capacity and runway throughput.

 However , as a strategy it can only

provide the future framework for change.

 In order to realize the changes that

will be delivered on the back of the FAS objectives.

 The application of technical &

• perational enablers will be key

amongst these.

 The specifications associated with

the ICAO Performance Based Navigation (PBN) concept offers the most opportunities for future airspace development.

PBN Current Status Needs

 It is a key step towards air space

modernization.

 Airspace design flexibility.  Airspace structure, Air Traffic

Management topography, Airport

• perator and CAA constrains.

 Predictable and repeatable path

trajectories moving to systemized environment with designed interactions.

 Closer spaced routes.  Curved path transitions.  Fuel savings- reduced track miles

and time saving.

 Increased revenues.  Fewer delays.  Fewer flight diversions.  Lower engine maintenance rates.

 Reduced environmental impact.  More effective aircraft utilization.  CO2 emission reduction.  Noise abatement.

 Improvement in quality of service to

meet new airspace user requirements.

PBN FUTURE PLANS USAGE

 Optimum air space utilization  ATS routes VS military training zones  Access to Non-instrument aerodromes  Improvement of existing approaches  Avoiding flying over military zones.  Future APV/Baro-VNAV approach to

Cairo, Sharm ,Hughada and other

• Intl. Airports.

 APV & LPV covering areas.

PBN – Future Plans Strategies

 Strategic objective  – Increase capacity and improve

efficiency of the aviation system in Egypt.

 Airspace Development.  Regulations ,e.g  Legislation and Regulations to support

PBN Implementation

 Regulations for PBN and GNSS use  Airworthiness Approvals

 R&D  Equipment  Training.

PBN – Future Plans Intl Carriers

 Intl Carriers  – Improved access  – Back up for ILS  – Efficiency, environment

General aviation (private)

 Improved access  – instrument Training  - UAV (Unmanned Aerial Vehicles),

Helicopters and aerial work

 – Oil Rigs  - SAR  – Electric, agriculture, Fire fighting

Other stakeholders, barriers to implementation Our main stake holders is Egypt Air. “supportive” weather and sensitive economic situation makes a complex business case

Looking forward

 GNSS is assimilated into majority of

Egypt aerial Inf.

 PBN implementation – Go Team,

Master Plan (with full stake holder involvement)

 Close relations with EGNOS and EU.

• Future air traffic management:

▪ Airspace planning & Air traffic flow management. ▪ Air traffic services & they are provided by air navigation service provider. ▪ Technology and air traffic control tools & it’s provided by engineering systems. ▪ Airspace users such as ( Air lines – Military & others ). ▪ Airports. ▪ Civil aviation authority.

• By achieving the PBN plan :

▪ Reduce the need to maintain sensor – specific routes and procedures and their associated costs. ▪ Avoid the need for developing sensor – specific

• perations with each new evaluation of navigation

which will be cost prohibitive. ▪ Allow for more efficient use of airspace ( Route placement, Fuel efficiency and noise abatement. ▪ Clarify how RNAV system are used. ▪ Facilitates the operational approval process for

• perators by providing a limited set of navigation

specifications intended for global use.

◊ PBN will :

• Improve services provided in Egyptian airspace.
• Improve knowledge for both Pilots and Controllers.
• Help stakeholders to determine their needs.
• Create an environment based on global concept.
• Improve economic fund.
• Create safe, efficient and flexible flight profile.
• Help us to reach to the global concept which is ONE

SBAS Supporting APV I/II

Presentation Overview

 Potential Benefits of APV  Requirements for the EGNOS

System

 Steps to enable the

Introduction of APV Applications

SBAS Operational Concept

 Conclusions

• APV procedures bring benefits
• SBAS Receiver could be Low Cost sensor for

P-RNAV or even RNP-RNAV

• Applications Supporting SIDs and STARs
• OCP are developing APV Criteria – SBAS

APV criteria expected to be applicable by

• Nov. 2006.
• Data Quality issues still to be solved
• Certification and operational approval

documents need amendments

ICAO Approach Types

 Non-Precision Approach (NPA)

• Lateral Guidance Only

 Approach with Vertical Guidance (APV)

• Lateral and Vertical Guidance
• Two Types –
• APV/Baro-VNAV
• APV-I and II supported by SBAS

 Precision Approach (PA)

• Lateral and Vertical Guidance
• Three Levels of Performance (Cat I, II and

III)

Where can APV be useful?

 Large Airports – As a fallback when ILS is out for

maintenance to maintain capacity

 Medium Sized Airport – Improve flexibility of

approach design, provide APV on secondary runways

 Small Airports – Cleaner approach procedures,

where conventional procedures are abnormal i.e. steep approach gradient, no direct approach etc..

 In addition – Sites with environmental

constraints, helicopters

International Context

 In the US WAAS APV (LPV) Procedures are

being implemented

• About 100 LPV procedures was published by

the end 2005

• First Certified Receivers are Appearing on

the market – i.e. Garmin GNS480

 In Europe

• Eurocontrol ECIP Objective to develop

Enablers for APV

• EC TEN-T Funding supporting Enabler

Enablers for APV

Procedures Design

 Criteria developed by ICAO OCP  Existing criteria for GPS NPA and

APV/Baro/VNAV

 SBAS APV Criteria was published by ICAO in

November 2006

 Euro control will develop guidance material

for the design and publication of SBAS APV procedures as part of the TEN-T funded task.

Enablers for APV Lighting Criteria

 Specific Lighting criteria exist

for today’s NPA and PA procedures

 NPA  PA Cat I

900 m 420 m

Lighting - 2

 Are the visual aids for NPA adequate

for APV?

 If not, then

• define the minimum requirements
• develop draft SARPS
• validate with simulations
• provide input to ICAO Visual Aids Panel

Enablers for APV

Flight Inspection

 Usual Flight Checks

• Path Definition is correct
• Obstacle clearance is sufficient
• Nav. aid coverage is available

 Requirements are in ICAO Doc 8071 – Manual on

Testing of Radio Navigation Aids

 The current requirements need to be reviewed

and guidance material developed for the flight inspection of SBAS APV procedures

Enablers for APV ATC and Flight Crew Procedures

 identify if specific ATC procedures are

required for APV approaches. This will require simulations to be performed.

 Flight Crew procedures may also be affected.  Review requirements and propose changes to

ICAO Doc 7030 as required

Enablers for APV Status Monitoring and NOTAMS

Issues

 SBAS Status information to ATC  NOTAMs  Legal Recording of Navaid Status (to support

accident investigation)

 Requirements Exist in ICAO – Are they relevant

to SBAS.

 How will system provided information be

distributed to ATC providers?

Validation of the Methodology

 First Step: Implementation Examples  Identify Airport and Operator and try to

implement an APV procedure.

 This will be done for a sample set of airports

proposed by States.

 Procedures will be designed, aircraft equipped

and flight demonstrations performed.

 It is hoped to be operating real example APV

implementations by the latter half of 2006

Flight Trials to date
