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

‘Tranche 2’ Changes approved at AP/2 October 2010 – to be review by ICAO Air Navigation Commission in March 2011 – State Letter to be issued June/July 2011. Aim to issue new Annex 14 Volume II – Heliports (Tranche 2) in July 2012.

ICAO HDWG planning to „start work‟ on completing

outstanding items later in 2011 – currently ‘on hold’ since no State as offered new HDWG Chair


Annex 14 STATUS

Heliports (including helidecks and shipboard heliports)

•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

(PinS) approach is used].

•Chapter 2: Heliport Data – No changes considered necessary.

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

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

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

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


a) Incorporation Certification and SMS requirements into Annex 14,Volume

II

b) Study of the „Applicability‟ of Annex 14, Volume II

c) Comprehensive revision of Annex 14, Volume II, Section 5.3, Lights

d) Review of „Airway Width‟ specifications for visual heliports and

development of specifications for heliports with instrument approaches and

departures.

e) Revised and updated guidance material for Doc 9261 Heliport Manual **

e) Comprehensive restructure of Annex 14, Volume II [The need for this is

being questioned by some States!]

** this is of major importance since Manual will detail how to apply ‘Annex 14 Volume II’

ICAO Heliport Manual, which is out of date and incorrect in some sections folowing the issue of the Tranche 1 changes, needs to be updated: HDWG is starting work on the sections on helidecks … no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 2011…. even so a replacement will not be available for a number of years!!

1.2 Applicability

Note.— The dimensions discussed in this Annex are based on

consideration of single-main-rotor helicopters. For tandem-

rotor helicopters the heliport design will be based on a case-by-

case review of the specific models using the basic requirement

for a safety area and protection areas specified in this Annex.

SCOPE OF „TRANCHE 1‟


1.2 Applicability






The specifications of the main chapters of this Annex are

applicable for visual heliports that may or may not incorporate

the use of a Point-in-space approach.

PROPOSED SCOPE OF „TRANCHE 2‟


1.2 Applicability






The specifications of the main chapters of this Annex are

applicable for visual heliports that may or may not incorporate

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.

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 are built using 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, in practice,

considerably less as a result of the „tranche 1‟ changes.


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]

In „tranche 2‟ new term FATO/TLOF introduced to cover elevated heliport and helidecks.

• *

** Currently difference in DLB requirements in FAA AC-2B and Annex 14:

FAA 1.5 x MTOW Annex 14 2.5 x MTOM

[Both applied through 2 points of contact.]

Note: covered in Heliport Manual – NOT addressed in Annex 14 – not reviewed to date by HDWG or any Sub-group.

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


DIFFERENCES

AC-2B ANNEX 14

PARKING AREA = HELICOPTER STAND

HOVER-TAXI = AIR-TAXI **

** „Hover Turns‟ - implied in „tranche 1‟ (2009) and referenced in „tranche 2‟


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 …

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

** US/FAA considers HOSPITAL HELIPORTS are essentially „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

than 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 (Pre-tranche 1) Annex 14

- FATO is equivalent to TLOF in FAA AC

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

of the TLOF’.

‘New’ 2009 ‘Tranche 1’ Annex 14

– FATO and TLOF in general terms same as in FAA AC
