  • Rule Material
  • New ACJs

  • RIA
  • So what has happened to it?
  • A feeling in the AWOSG that some final editorial
    work required before public consultation
    (including compliance with JAR 11!)
  • More harmonisation work with FAA and ICAO
  • Workshop on November 10

5
Contents of Todays Presentation

6
NPA-OPS 41
  • The proposal contains draft texts for
  • Aerodrome Operating Minima (1.430)
  • Comments received post NPA 20
  • JAA / FAA AWOHWG work (ongoing)
  • Requirements for Cat I, II and III Operations
    (1.440 and Appendix)
  • JAA / FAA AWOHWG work
  • Introduction of HUD HUDLS
  • Introduction of EVS
  • Training and qualification requirements for all
    of the above (1.450)

7
Stabilised Instrument Approach - Background
  • CFIT ALARP programmes encouraged authorities to
    prescribe stabilised instrument approaches SAp
  • SAp an approach which is flown in a controlled
    and appropriate manner in terms of configuration,
    energy and control of the flight path, from a
    pre-determined point or altitude/height, without
    any segment of level flight at MDA(H)
  • Considered to be much safer than a Non-Precision
    Approach (NPA) flown as dive drive

8
Stabilised Instrument Approach and CDFA
  • NPA 20 / 41 defines a new variant of the
    Stabilised Approach the Continuous Descent Final
    Approach (CDFA)
  • An approach with a predetermined approach slope
    which enables a continuous descent to DA(H)
  • CDFA includes precision approaches,
    non-precision approaches and approaches with
    vertical guidance (APV)

9
CDFA - Benefits
  • The CDFA concept aims to increase the safety of
    Non-Precision Approaches by eliminating level
    flight at MDA, ie close to the ground
  • Pilot workload is reduced as a/c attitude, power
    and energy are stabilised
  • One decision point for the pilot
  • The intention is that all approaches should be
    flown as CDFA (if possible)

10
CDFA v Traditional NPA
Continuous descent from FAF no level-flight
segment at MDH
11
Harmonisation Work
  • Meeting of JAA / FAA AWO Harmonisation Working
    Group in September
  • FAA members participated in AWOSG meeting
    November 1-3
  • FAA will soon publish revised Ch 3 of TERPS
    (harmonised AOM) for consultation
  • Some changes to ICAO PANS Ops incorporated

12
NPA 41 Workshop 10 Nov 05
  • Requirement from OST in May to introduce the NPA
    41 material to interested parties
  • Attended by 25 representatives
  • Mostly from Europe, but also Australia and
    Secretary of ICAO OPSP
  • Subjects covered included
  • Purpose, Background and Harmonisation Work
  • CDFA and SAp
  • New Technology (HUD EVS)
  • New Minima and Minima Calculation
  • RNAV Issues
  • Charting Issues
  • Possible Future Developments
  • Comments?

13
Detailed Rule, Appendix and ACJ Changes Since
OST 05/2
14
Most Important!
  • There have been no changes to the philosophy of
    the NPA since May
  • Only one detailed Rule change is proposed
    (explanation later...)
  • Most of the changes are editorial, designed to
    explain and simplify
  • We are not proposing anything vastly different
    since your previous endorsement!
  • But... because changes have been made, the
    material has been brought back

15
Rule Changes
  • (d)(1) (2) CDFA and SAp are separated more
    clearly
  • (d)(2) clarifies that CDFA only applies to
    Non-precision approaches
  • (f) deleted as a consequence of (d)(2)
  • 1.430 Aerodrome Operating Minima General

16
Rule Changes
  • 1.435 Terminology
  • (a)(10) Definition of SAp aligned with ICAO PANS
    Ops Vol 1
  • (a)(15) Definition of Converted Meteorological
    Visibility (CMV) introduced
  • (a)(16) Definition of Lower Than Standard
    Category I included
  • (a)(17) Definition of Other Than Standard
    Category II included
  • ( NB these definitions previously endorsed by
    OST)

17
Rule Changes
  • General Comment
  • Most references to RVR changed to include CMV
    (Rule Appendix)
  • Many references to DA(H) changed to DH because
    they refer to height above the ground

18
Appendix 1 to 1.430
  • (b) Cat I, APV and NPA referred to as
    operations
  • (b)(3) RNAV/Baro VNAV removed from definition of
    APV
  • (c)(1) lowest usable added
  • (c)(1)(i) (ii) CDFAs replaced with
    instrument approaches
  • (c)(2) New para
  • (d)(1) Added but not greater than the maximum
    values shown in table 6 where applicable for
    clarity

19
Appendix 1 to 1.430
  • (d)(5) Reworded and simplified
  • Special requirements for DH 200 210 ft deleted
  • ILS requirements simplified
  • Guidance required down to DH only
  • (d)(8) New para based on text agreed at OST 05/2,
    proposed by ERA
  • Table 6 Note added at the bottom for clarity
  • (d)(10) Simplified in similar way to (d)(5)
  • (e)(2) (f)(1(iii) Max offset angle limited to 3
    degrees instead of 5 degrees
  • Tables 6a and 6b combined note moved to become
    (e)(5)(1)

20
Appendix 1 to 1.430
  • Tables 7b and 7c combined
  • (h)(1)(i)(B) (C) and (h)(3) Visual reference
    requirements changed to harmonise completely with
    FAA
  • (h)(2) Added APV
  • (j) Only real Rule change. Reinstated the link
    between minima for circling and preceding
    instrument approach but only for offset
    approaches, not circling to an opposite runway
  • (l) Slight change of wording for clarity

21
ACJs
  • 1.430 CDFA
  • Edited extensively to improve English
  • Discussion about amount of information your
    views sought
  • Appendix 1 (New) to 1.430 (d) AOM
  • Considerably simplified

22
ACJs
  • Appendix 1 (New) to 1.430 (f) Circling
  • Should be (j) not (f) sorry!
  • Endorsed by OST, believed to be in 2002, cold
    item
  • To replace current IEM to Appendix 1 to JAR-OPS
    1.430, paragraph (f)
  • Not contentious
  • Requested from the AWOSG
  • A good opportunity to include it

23
Regulatory Impact Assessment
24
RIA
  • Scope
  • Discussed already
  • Relevant ICAO / JAA decisions
  • SAp / CDFA
  • HUD (JAA TGL)
  • HUD minima conflict with Annex 14 (RVR not DH)
  • NPA may well be used by ICAO OPSP
  • Operations lt550m RVR definition (Cat I or Cat
    II?)

25
RIA
  • Objectives
  • Enhance safety especially CDFA
  • HUDLS / autoland
  • EVS
  • Who will be affected?
  • All JAR-OPS operators, and probably most GA
  • Training
  • New operational procedures

26
RIA
  • Options
  • Do nothing
  • Introduce Rule, but no reduction in RVR
  • Introduce Rule and reduce required RVR
  • Mandate CDFA / SAp, but no change in AOM
  • Mandate CDFA / SAp and change in AOM

27
RIA
  • Equity and Fairness
  • Equal and fair procedures in Europe and USA
  • Regulation for new technologies
  • Lower minima depending on installed equipment
  • Europes need to catch up with FAA

28
RIA
  • Impacts identified
  • Safety
  • Economic
  • Harmonisation
  • Environmental
  • Social (nil)
  • Other Aviation Requirements

29
RIA
  • Consultation
  • Industry
  • Flight-crew
  • FAA
  • Comments Response Document
  • Summary Final Assessment

30
Conclusion
  • No major changes have been made since OST 05/2
  • Many of the items have been endorsed separately
    by the OST at various times in the past
  • Circling ACJ
  • HUD material
  • NPA 20
  • NPA 41 (first draft)
  • This major reworking of Sub Part E is overdue and
    should be well received by the aviation community
