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’: some

additional 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 –

c hanges to ‘markings’ to be issued as part of tranche 2, lighting 40 % complete – still

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 2 Surface-level Heliports Chapter 3 Elevated Heliports Chapter 4 Instrument Heliports Chapter 5 Helidecks

Chapter 6 Shipboard Heliports and Winching Areas

and each Chapter will consist of the following

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ICAO Heliport Manual, which is out of date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 3 rd

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

FAA AC 150/5390-2B-2B (AC-2B) Heliport Design was issued

of FAA and other web sites - the following is one useful web

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

GENERAL

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!
