ACAS INTRODUCTION

• ACAS II PLAYS CENTRAL ROLE IN RESOLVING AIRPROX
  WITH RISK OF COLLISION

4
ACAS INTRODUCTIONTERMINOLOGY

• ?ACAS II is the level of ACAS defined in ICAO
  SARPs - the system
• ?Traffic Alert and Collision Avoidance System
  (TCAS) II complies with ACAS II SARPs - the
  equipment

5
ACAS II INTRODUCTIONPURPOSE FUNCTION

• ?Designed to reduce risk of mid-air collision -
  using SSR technology to detect and track nearby
  aircraft
• ?TCAS II provides two levels of alert
• TA - indication of traffic that may become a
  threat
• RA - issued if a risk of collision calculated

6
ACAS II INTRODUCTIONPURPOSE FUNCTION (Cont)

• ? RAs provide pilot with indication the
  flight-path change (vertical plane only) to avoid
  collision
• ? When both aircraft are TCAS equipped, RAs are
  coordinated

• ?REVISED DOCUMENTATION
• ?AVAILABLE TRAINING MATERIAL

8
ACAS REGULATION TRAINING GENERAL

• ? The ACAS II equipment is a proven independent
  airborne safety net.
• ? Nevertheless, to ensure that its operational
  effectiveness is maximised, both pilots and
  controllers need to understand ACAS II
  operational principles, and correctly apply the
  standard operational procedures.

9
ACAS REGULATION TRAINING(CONT)

• ? Actions shall be taken by State regulators, air
  navigation service providers, aircraft operators,
  ICAO, JAA, Associations and EUROCONTROL to
  reinforce ACAS provisions and Guidance Material
  and to remove any ambiguity

10
ACAS REGULATION TRAINING REVISED PROCEDURES

• ? PANS-OPS Doc 8168
• Revised ACAS Procedures and Pilot Training
  Guidelines
• ?PANS-ATM Doc 4444
• Reviewed to ensure consistency and completeness
• ?JAR-OPS
• Being amended to reflect revised PAN-OPS
• ?SSAP Requirements Not a wish list. Essential
  and High Priority

11
PAN-OPS Doc 8168 REVISION

• ? The new procedures result out of the experience
  gained from a decade of worldwide ACAS II
  operations and as a result of several monitoring
  programmes.
• ? The most important change is related to the
  procedure when an RA is generated. The new
  procedure clearly states that

12
PAN-OPS Doc 8168 REVISION (Cont)

• ? Pilots shall respond immediately by following
  the RA as indicated, unless doing so would
  jeopardise the safety of the aeroplane.
• ? Pilots shall follow the RA even if there is a
  conflict between the RA and an ATC instruction to
  manoeuvre.
• ? Pilots shall not manoeuvre in the opposite
  senseof an RA.

13
PAN-OPS Doc 8168 REVISION (Cont)

• ? PANS-OPS now states that visual acquisition is
  no longer an acceptable reason not to follow an
  RA
• ?Visually acquired traffic may not be the same
  traffic causing an RA. Visual perception of an
  encounter may be misleading, particularly at
  night.

14
PAN-OPS Doc 8168 REVISION (Cont)

• ? In addition, the need for pilots to notify all
  RAs to the controller is reinforced
• ? Pilots shall, as soon as permitted by flight
  crew workload, notify the appropriate ATC unit of
  the RA, including the direction of any deviation
  from the current ATC instruction or clearance.

15
ACAS TRAINING GENERAL

• ? Every effort must be made to ensure that the
  relevant operations manuals include up-to-date
  ACAS procedures, and that appropriate training
  is provided to ensure that pilots and
  controllers are able to apply these standard
  ACAS procedures consistently.

16
ACAS TRAINING AVAILABLE

• FOR PILOTS AND CONTROLLERS
• ? ACAS Information booklet
• ? IANS Course material
• Event replay software -Replay Interface for TCAS
  Alerts (RITA)
• ACAS Operations in RVSM ACTOR
• ? ACAS II Safety Bulletins

ACAS II MANDATE PHASE 2 TRANSITIONAL ARRANGEMENTS

• ?PHASE 2 MANDATE
• ?THE ISSUES
• ?THE TRANSITIONAL ARRANGEMENTS

19
ACAS II PHASE 2 MANDATE

• ? With effect from 1 January 2005, all civil
  fixed wing turbine-engined aircraft having a
  maximum certificated take-off mass exceeding
  5700kg, or a maximum approved passenger seating
  configuration of more than 19, will be required
  to be equipped with ACAS II

20
IMPLEMENTATIONISSUES

• ? Transitional arrangements were developed
  because some operators of Phase 2 aircraft will
  be unable to achieve ACAS II equipment
  installation on their aircraft by 1 January 2005
  because of the following implementation issues

21
IMPLEMENTATIONISSUES (Cont)

• ? non-availability of an ACAS II SB/STC or
• ? certification problems/delays in the
  development of SBs and STCs, are delaying the
  installation programme of Mode S transponder
  equipment compliant with the mandatory
  requirement for Mode S Elementary Surveillance
  (ELS) and Enhanced Surveillance (EHS).
• ? A number of operators of Phase 2 aircraft are,
  for practical engineering and installation cost
  considerations, seeking to combine their ACAS
  II installations with the installation of Mode S
  transponder equipment which is Mode S ELS and
  EHS compliant.

22
TRANSITIONAL ARRANGEMENTS

• ? To address the identified implementation
  issues, the following Transitional Arrangements
  have been approved by the PC
• ? the Phase 2 mandate date, 1 January 2005, will
  be maintained. This supports the requirements
  of ICAO Annex 6 SARPs and JAR OPS.
• ? the final date for compliance will be 31 March
  2006. This date has been selected on the advice
  of industry representatives, to enable operators
  to schedule their ACAS II installation in line
  with maintenance schedules, whilst ensuring that
  the pressure to comply with the mandatory
  requirement to install and operate ACAS II is
  maintained.

23
TRANSTIONAL ARRANGEMENTS (Cont)

• ? To ensure that individual States authorities
  are not burdened by excessive exemption requests,
  the Agencys ACAS Mode S Programme will manage
  and coordinate the transitional arrangements on
  behalf of the ECAC states
• ? An aircraft exemption granted under the
  Transitional Arrangements will be temporary,
  specific to each airframe number and will not be
  transferable. Each exemption request will be
  considered on a case-by-case basis.

24
PROMULGATION OF THE TRANSITIONAL ARRANGEMENTS

• ? A specimen AIC has been developed, explaining
  clearly the Phase 2 transition arrangement
  provisions. This AIC has been distributed to the
  Authorities throughout the ECAC States, with the
  request that it be adopted at the earliest
  possible AIRAC date.
• ? Details of the Arrangements have been forwarded
  to all European Operators of Phase 2 aircraft, to
  Aircraft and ACAS II equipment manufacturers and
  to relevant Industry and Aviation bodies eg ERA.
  The Agency is also developing various publicity
  campaigns.
