PRESENTATION TERMINLOGY



Annex 14 UPDATE PROGRESS

HDSG formed late 2003

HDSG/1 Meeting May 2004 [AP formed Dec 2004]

HDWG/1 Meeting June 2005

[Agreed changes should be addressed in 2 parts – tranche 1 and 2]

HDWG/2 – June 2006

First set of changes (Tranche 1) agreed at HDWG/2 (June 2006) –

Changes endorsed by the „WG of the Whole‟ at WGoTH/3 meeting

(August 2006)

Approved by Aerodrome Panel at AP/1 December 2006.

Tranche 1 Changes approved by ICAO ANC May 2007

ICAO „State Letter‟ ** issued with „Tranche 1 changes‟ August 2007.

** State Letter included also changes to Annex 14 Volume 1 related to Aerodromes



CURRENT STATUS

Updated Annex 14 Volume II – Heliports (Tranche 1)

.......... Issue July 2009:

................applicability date 19 November 2009!

Note: Some ‘helideck requirements’ have later applicability date of 2012

HDWG now finalizing ‘Tranche 2’ Changes

ICAO AP/2 to address ‘tranche 2’ changes, originally planned for 2009, now October 2010.

HDWG planning to ‘start work’ on updating the ICAO Heliport Design Manual (Doc 9261) in 3rd Quarter of 2010 ? – this is of major importance since Manual will detail how to apply ‘Annex 14 Volume II’



Annex 14 STATUS

•Chapter 1: General (Definition) - main changes completed in ‘tranche 1’ - addition changes to be made in tranche 2 to cover ‘floating (pontoon) heliports’ etc., and to ensure requirements for VFM (VFR) heliports cover also heliports where an instrument

(Point in Space/PinS) approach is used.

•Chapter 2: Heliport Data – tranche 2 minor changes.

•Chapter 3: Physical Characteristics – main changes completed in ‘tranche 1’: someadditional changes and new term ‘FATO/TLOF’ for elevated heliports and helidecks to be made in tranche 2.

•Chapter 4: Obstacle Restriction and Removal (Airspace) : Study completed for VFM (VFR) heliports - to be issued as part of tranche 2.

•Chapter 5: Visual Aids (Markings & Lighting) - minor changes issued in tranche 1 –changes to ‘markings’ to be issued as part of tranche 2, lighting 40 % complete – still being ‘worked’ – changes to ‘lights’ to be made post-tranche 2.

•Chapter 6: Heliport Services (Fire Fighting) – being addressed by separate RFFWG



Annex 14 Future Work

ICAO agreed –at AP1 (Dec 2006)- for Annex 14 to be reformatted to

make it easier to use – the existing and „new‟ text will be grouped in

the following Chapters:-

Chapter 1. General

Chapter 3. Elevated Heliports

Chapter 4. Instrument Heliports

ICAO DOCUMENTS

ICAO Heliport Manual, which is out of date and incorrect in some sections folowing the issue of the Tranche 1 changes, needs to be updated: HDWG is starting work on the sections on helidecks … no specific plans for addressing heliports: aim to decide by 3rd

quarter of 2010…. even so a replacement will not be available for a number of years!!

PRESENTATION TERMINOLOGY

RD = ROTOR DIAMETER

D = „D-value‟ = OVERALL LENGTH (OL)

UCw = UNDERCARRIAGE WIDTH/LENGTH

PC1, PC2 & PC 3 is used to refer to heliports designed on

the assumption that they are “intended to be used by

helicopters operated in performance class 1” or

“performance class 2 and 3” respectively.

The „diagrams‟, although illustrating the approximate relative sizes are

NOT to scale - this is not stated on all diagrams.

US (FAA) AC150/5390-2B

FAA AC 150/5390-2B-2B (AC-2B) Heliport Design was issued on 9/30/04 (30 September 2004) and is available on a number of FAA and other web sites - the following is one useful web site to obtain the document:-

http://www.faa.gov/arp/publications/acs/5390-2/5390-2b.pdf

Hardcopies are NOT available from the FAA – they are available from a number of commercial suppliers at a fee.

NOTE: AC-2B is an “Advisory Circular” i.e. Guidelines … but is a Requirement for heliports which use Federal Funds and is a Requirements in a number of the US States.



Annex 14/FAA

MAJOR DIFFERENCES

ICAO ANNEX 14 ~ FAA AC 150-5390-2B*

• ANNEX 14 BASED ON “OPERATIONAL

PERFORMANCE” REQUIREMENTS (HELICOPTER PERFORMANCE CLASS) DEFINED IN ANNEX 6

• FAA AC-2B BASED ON HELIPORT TYPE (USE).

• Main Technical Differences • Load Bearing Area Size Requirements**• Airspace Requirements

*Issued by FAA in September 2004.

** Differences between „Annex 14 Vol II‟ and FAA AC-2B are considerably less

as a result of the „tranche 1‟ changes.



AIM•EXPLANATION OF TERMINOLOGY AND CONCEPTS USED IN

ICAO ANNEX 14 Vol II

•DISCUSSION AND OUTLINE OF :-

(i) Changes in Annex 14 „tranche 1‟ issued July 2009

(ii) Additional changes being considered by the ICAO HELIPORT

DESIGN WORKING GROUP (HDWG) for „tranche 2‟ .... and some

„Post-Tranche 2‟ changes.

(iii) Review of main differences between US/FAA Heliport Design AC

150/5390-2B (AC-2B) and „tranche 1‟ ICAO Annex 14 „standards and

recommended practices‟ (SARPS) for heliports

ELEVATED HELIPORTS

FATO AND TLOF ARE “COINCIDENTAL” *

(i.e. SAME SIZE – 1D or 0.83 D)… and FATO IS DLB.

DLB = Dynamic Load Bearing **

* Also applies to Helidecks

** Currently difference in DLB requirements:

FAA 1.5 x MTOW Annex 14 2.5 x MTOM

[Both applied through 2 points of contact.]

Covered in Heliport Manual – NOT addressed in Annex 14 – not reviwed to date by HDWG or any Sub-group.

ICAO/International MTOM (Max Takeoff Mass) = US MTOW (Max Takeoff Weight)

ICAO FRAMEWORK

• PPR (Private Use) Heliports Not Directly Considered In Annex 14 [Only Brief Reference To PPR Heliports Made In This Presentation]

• Annex 14 covers Hospital Heliports ** - Most European Nations consider Annex 14 Applies To All „Public Interest‟ Facilities including Hospital Heliports.

• “Europe” considers Hospital Heliports should be designed for Performance Class 1 operations –requirement of JAR OPS 3 …

... or with a DLB Area (FATO + Safety area) of 2D

** US/FAA considers HOSPITAL HELIPORTS are „PRIVATE USE‟



GENERAL

• PC2 and PC3 Heliports in ICAO Annex 14

corresponds to General Aviation Heliport in FAA

AC.

• PC1 Heliport in ICAO Annex 14 is approximately

the same as Transport Heliport in FAA AC … but is

Annex 14 based on PC1/Cat A performance rather

that dimensions related to size of helicopter as in

FAA AC-2B: in this case Annex 14 generally less

demanding and more logical than FAA AC-2B!

PC2/PC3 Heliports

2004 Annex 14

- FATO is equivalent to TLOF in FAA AC

- TLOF of 1.5UC is similar to PPR ‘2UC paved portion

of the TLOF’.
