NPA No. 09/2013

CIVIL AVIATION ADVISORY PUBLICATION (CAAP) 71 HELIDECKS (OFF-SHORE)

Release Date: 18 July 2013

The General Civil Aviation Authority (GCAA) has concluded a review into the regulatory and safety oversight of aerodromes1 within the UAE. This review has included aerodromes and heliports / helidecks.

As a consequence, an evaluation has been undertaken of the requirement for helidecks with reference to ICAO Annex 14 Volume II (Heliports) and the approach to provide safety oversight for off-shore helidecks in the UAE.

This NPA is introducing a new CAAP as detailed in Section B to this NPA and is also introducing changes to Civil Aviation Regulations as detailed in Section A to this NPA.

The aim of this CAAP is to provide guidance to operators of helidecks; it also aims to introduce a process for safety oversight.

The proposed CAAP should ensure compliance with the UAE Civil Aviation Law; Civil Aviation Regulations (referenced below) and conformance with the international standards of ICAO Annex 14, Volume I (Aerodromes) and Volume II (Heliports).

CAR PART IV, OPS 3.220 (Commercial and Private Air Transportation: Helicopters):Authorisation of Heliports by the Operator: “An operator shall only authorise use of heliports that are adequate for the type(s) of helicopter and operation(s) concerned”.

The implementation of the GCAA regulatory and safety oversight process will however, commence at a later date, (a date will be provided by a GCAA publication, following the publication of the CAAP and the amended Civil Aviation Regulations).

CAAP 71 will be subject to change as a result of ICAO Amendment Number 5 to ICAO Annex 14 Volume II which, subject to adoption by the ICAO Council, will become applicable on 14th November 2013. The ICAO “Effective Date” is 15th July 2013, following which information can be obtained on request; email: [email protected].

The CAAP and the amendment to the Civil Aviation Regulations will be issued once the NPA and consultation process has been completed.

This Notice of Proposed Amendment is published for the aviation industry, all concerned parties and appropriate local authorities in each Emirate, in order to:

1. Review the attached proposed publication; 2. Submit their comments online through the GCAA website by 31st October 2013 from the date

of this NPA.

1 A defined area on land or water (including any buildings, installations and equipment) intended to be used either wholly or in

part for the arrival, departure and surface movement of aircraft.

Section A to NPA 09-2013

1. PROPOSED AMENDMENT TO CAR PART IX (AERODROMES)

1.1 Applicability (Chapter 1 paragraph 1.2.1): These Regulations apply to all aerodromes served by aircraft conducting an Air Service within the UAE, and other aerodromes which provide operations using instrument approach or departure procedures.

1.2 Definition (Chapter 1 paragraph 1.3.3):

a) Deletion of: Aerodrome Certificate – Low Capacity

b) Addition of: Aircraft or Helicopter Landing Area Acceptance - landing areas which are not for Air Service operations and do not have instrument runways. (Excluding areas used solely for Light Sport Aircraft).

1.3 Requirements to hold an Aerodrome or Heliport Certificate or an Aircraft or Helicopter Landing Area Acceptance (Chapter 2 paragraph 2.1.1): An operator of an aerodrome served by aircraft conducting an Air Service and other aerodromes which provide operations using instrument approach or departure procedures shall be in possession of an Aerodrome or Heliport Certificate.

An operator of a landing area which is not providing an Air Service and which does not have instrument runways, shall hold an Aircraft or Helicopter Landing Area Acceptance, (excluding areas used solely by Light Sport Aircraft).

(It is proposed that reference will be made to CAAP 71, which will become regulation under CAR Part IX).

1.4 Appendix 16 - Heliports2: This currently directs readers to ICAO Annex 14 Volume II. When the process for GCAA regulatory oversight at heliports is implemented, the content of CAAP 71 will be transferred to CAR Part IX and referred to as GCAA Regulation.

2. AERODROME (HELIPORT) CERTIFICATE OR AIRCRAFT (HELICOPTER) LANDING AREA ACCEPTANCE

2.1 Aerodrome operators are advised to assess their operations against Table 1, which provides additional clarity regarding the conduct of an Air Service.

a) Aerodrome or Heliport Certification:

This applies to aerodromes which are open to public use and which serve Commercial Air Transport offering an Air Service and other aerodromes which provide operations using instrument approach or departure procedures.

Reference shall be made to CAR Part IX and CAAP 30 (The Issue & Renewal of an Aerodrome Certificate), which refers to the process to be followed to gain an Aerodrome or Heliport Certificate.

b) Aircraft or Helicopter Landing Area Acceptance:

This applies to landing areas which are not for Air Service operations and do not have instrument runways, (excluding areas used solely for Light Sport Aircraft).

2 Heliport mean an aerodrome or a defined area on a structure intended to be used wholly or in part for the arrival, departure

and surface movement of helicopters.


3. GCAA REGULATORY OVERSIGHT: HELIPORTS

3.1 Physical characteristics (dimensions) and visual aids will require approval or acceptance from the Air Navigation and Aerodrome Department, with reference to CAR Part IX and CAAP 70.

3.2 Operational aspects in terms of: flight direction, operating procedures and obstacle limitation surfaces, dependent upon the largest set of dimensions and performance criteria that a heliport is intended to serve, will receive oversight from Flight Operations Department with reference to CAR Part IV-OPS 3.

4. IMPLEMENTATION OF REGULATION

4.1 The date for the proposed amendment to CAR Part IX and for the implementation of the GCAA regulatory and safety oversight process will be notified by a GCAA publication.

4.2 It is intended that implementation will be in the form of a phased approach, with new construction and operations conforming to regulation from the implementation date.

4.3 Actions to achieve compliance with regulation at existing locations will be phased over a period of time in agreement with the GCAA.

4.4 It will be a requirement to hold a certificate or landing area acceptance in order to operate or to continue operations.

5. SERVICE FEES

5.1 Aerodrome or Heliport Certificate holders and holders of Aircraft or Helicopter Landing Area Acceptance will be subject to initial and ongoing annual fees.


TABLE 1: REQUIREMENTS FOR AERODROME / HELIPORT CERTIFICATION OR AIRCRAFT / HELICOPTER LANDING AREA ACCEPTANCE REGARDING THE CONDUCT OF AN AIR SERVICE This Table should be used to evaluate if operations require an aerodrome to be certificated under the definition of “Air Service” (UAE Civil Aviation Law) with operations as referred to in paragraph 5, or to following the Aircraft Landing Area Acceptance process as described in CAAP 70 and CAAP 72.

NOTE 1: The categorisation of flights for Public Transport may differ for Flight Crew Licensing, Flight Operations and Airworthiness. Applicable Regulation should therefore apply. The issue of an Aerodrome / Heliport Certificate or Aircraft /Helicopter Landing Area Acceptance, does not constitute an “approval” from Flight Operations Department. NOTE 2: For landing areas categorised as “Acceptance” and not part of the audit/inspection programme, the GCAA assumes no responsibility for the condition of the landing area, presence of obstacles or operations at the location.

CHAPTER 3 – PHYSICAL CHARACTERISTICS: HELIDECKS

Note – In addition to the specification listed within this Chapter, reference shall also be made to CAAP 70.

Note —The following specifications are for helidecks located on structures engaged in such activities as mineral exploitation, research or construction. See Chapter 4 for shipboard heliport provisions.

1. FINAL APPROACH AND TAKE-OFF AREAS AND TOUCHDOWN AND LIFT-OFF AREAS

Note — On helidecks it is presumed that the FATO and the TLOF will be coincidental. Reference to FATO within the helideck section of this CAAP is assumed to include the TLOF. Guidance on the effects of airflow direction and turbulence, prevailing wind velocity and high temperatures from gas turbine exhausts or flare radiated heat on the location of the FATO is given in the Heliport Manual (Doc 9261).

1.1 A helideck shall be provided with at least one FATO.

1.2 A FATO may be any shape but shall be of sufficient size to contain:

a) for helicopters with an MTOM of more than 3,175 kg, an area within which can be accommodated a circle of diameter not less than 1.0 D of the largest helicopter the helideck is intended to serve; and

b) for helicopters with an MTOM of 3,175 kg or less, an area within which can be accommodated a circle of diameter not less than 0.83 D of the largest helicopter the helideck is intended to serve.

1.3 Recommendation — For helicopters with an MTOM of 3,175 kg or less, the FATO should be of sufficient size to contain an area within which can be accommodated a circle of diameter not less than 1.0 D of the largest helicopter the helideck is intended to serve.

1.4 A FATO shall be dynamic load-bearing.

1.5 A FATO shall provide ground effect.

1.6 No fixed object shall be permitted around the edge of the FATO, except for frangible objects, which, because of their function, must be located thereon.

1.7 Objects whose function require them to be located on the edge of the FATO shall not exceed a height of 25 cm, except that in the case of a FATO of diameter less than 1 D, the maximum height of such objects shall not exceed a height of 5 cm.

1.8 Objects whose function requires them to be located within the FATO (such as lighting or nets) shall not exceed a height of 2.5 cm. Such objects may be present only if they do not represent a hazard to helicopters.

Note — Examples of potential hazards include nets or raised fittings on the deck that might induce dynamic rollover for helicopters equipped with skids.

1.9 Safety net or safety shelves shall be located around the edge of a helideck but shall not exceed the helideck height.

1.10 The surface of the FATO shall be skid-resistant to both helicopters and persons and be sloped to prevent pooling of water.

Note — Guidance on rendering the surface of the FATO skid-resistant is contained in the Heliport Manual (Doc 9261).


CHAPTER 4 – PHYSICAL CHARACTERISTICS: SHIPBOARD


When helicopter operating areas are provided in the bow or stern of a ship or are purpose-built above the ship’s structure, they shall be regarded as purpose-built shipboard heliports.

1 FINAL APPROACH AND TAKE-OFF AREAS & TOUCHDOWN AND LIFT-OFF AREAS

Note — On shipboard heliports, it is presumed that the FATO and the TLOF will be coincidental. Reference to FATO within the shipboard heliport section of this Annex is assumed to include the TLOF. Guidance on the effects of airflow direction and turbulence, prevailing wind velocity and high temperature from gas turbine exhausts or flare radiated heat on the location of the FATO is given in the Heliport Manual (Doc 9261).

1.1 Shipboard heliports shall be provided with at least one FATO.

1.2 The FATO of a shipboard heliport shall be dynamic load-bearing.

1.3 The FATO of a shipboard heliport shall provide ground effect.

1.4 For purpose-built shipboard heliports provided in a location other than the bow or stern, the FATO shall be of sufficient size to contain a circle with a diameter not less than 1.0 D of the largest helicopter the heliport is intended to serve.

1.5 For purpose-built shipboard heliports provided in the bow or stern of a ship, the FATO shall be of sufficient size to:

a) contain a circle with a diameter not less than 1 D of the largest helicopter the heliport is intended to serve; or

b) for operations with limited touchdown directions, contain an area within which can be accommodated two opposing arcs of a circle with a diameter not less than 1 D in the helicopter’s longitudinal direction. The minimum width of the heliport shall be not less than 0.83 D (see Figure 4-1).

Note 1 — The ship will need to be manoeuvred to ensure that the relative wind is appropriate to the direction of the helicopter touchdown heading.

Note 2 — The touchdown heading of the helicopter is limited to the angular distance subtended by the 1 D arc headings, minus the angular distance which corresponds to 15 degrees at each end of the arc.

1.6 For non-purpose-built shipboard heliports, the FATO shall be of sufficient size to contain a circle with a diameter not less than 1 D of the largest helicopter the helideck is intended to serve.

1.7 No fixed object shall be permitted around the edge of the FATO, except for frangible objects, which, because of their function, must be located thereon.

1.8 Objects whose function requires them to be located on the edge of the FATO shall not exceed a height of 25 cm.


1.10 The surface of the FATO shall be skid-resistant to both helicopters and persons.

Figure 4-1 Shipboard permitted landing headings for limited operations



CHAPTER 5 – PHYSICAL CHARACTERISTICS: SAFETY NET & STRUCTURAL DESIGN

1. SAFETY NET4

1.1 Safety nets for the protection of personnel should be installed around the helideck except where structural protection exists. The netting used should be of a flexible nature and be manufactured from non-flammable material. The inboard edge should be fastened level with, or just below, the edge of the helideck, including drainage, guttering, etc. The net itself should extend at least 1.5 m in the horizontal plane and be so arranged that the outboard edge is slightly above the level of the helideck edge, but by not more than 0.25 m, having an upward and outward slope of at least 10 degrees. The net should be strong enough to withstand, without damage, a 75 kg mass being dropped from a height of 1.0 m.

1.2 A safety net designed to meet these criteria may nevertheless be too rigid and act as a trampoline giving a "bounce" effect. Further, if lateral or longitudinal centre bars are provided to strengthen the net structure, there is a risk of serious injury to persons falling across them. The ideal design should produce a "hammock" effect which should securely contain a body falling or jumping into the net, without injury.

2. STRUCTURAL DESIGN STRENGTH5

2.1 Elevated helidecks may be designed for a specific helicopter type though greater operational flexibility will be obtained from a classification system of design. The FATO should be designed for the largest or heaviest type of helicopter that it is anticipated will use the helideck, and account taken of other types of loading such as personnel, freight, refueling equipment, etc. For the purpose of design, it is to be assumed that the helicopter will land on two main wheels, irrespective of the actual number of wheels in the undercarriage, or on two skids if they are fitted. The loads imposed on the structure should be taken as point loads at the wheel centres; details are specific in the ICAO Doc 9261: Heliport Manual.

4ICAO Heliport Manual (Doc 9261) Chapter 1, paragraph 1.4.4

5ICAO Heliport Manual (Doc 9261) Chapter 1, paragraph 1.4.6


CHAPTER 6 – OBSTACLE RESTRICTION AND REMOVAL

Note – In addition to the specification listed within this Chapter, reference shall also be made to CAAP 70 with reference to restriction and removal.

Note — The objectives of the specifications in this chapter are to define the airspace around heliports to be maintained free from obstacles so as to permit the intended helicopter operations at the heliports to be conducted safely and to prevent the heliports becoming unusable by the growth of obstacles around them. This is achieved by establishing a series of obstacle limitation surfaces that define the limits to which objects may project into the airspace.

1 OBSTACLE-FREE SECTOR / SURFACE - HELIDECKS

Description. A complex surface originating at and extending from a reference point on the edge of the FATO of a helideck. In the case of a FATO of less than 1 D, the reference point shall be located not less than 0.5 D from the centre of the FATO.

Characteristics. An obstacle-free sector/surface shall subtend an arc of specified angle.

1.1 A helideck obstacle-free sector shall comprise two components, one above and one below helideck level (see Figure 6-1):

a) Above helideck level. The surface shall be a horizontal plane level with the elevation of the helideck surface that subtends an arc of at least 210 degrees with the apex located on the periphery of the D reference circle extending outwards to a distance that will allow for an unobstructed departure path appropriate to the helicopter the helideck is intended to serve.

b) Below helideck level. Within the (minimum) 210-degree arc, the surface shall additionally extend downward from the edge of the FATO below the elevation of the helideck to water level for an arc of not less than 180 degrees that passes through the centre of the FATO and outwards to a distance that will allow for safe clearance from the obstacles below the helideck in the event of an engine failure for the type of helicopter the helideck is intended to serve.

Note — For both the above obstacle-free sectors for helicopters operated in performance class 1 or 2, the horizontal extent of these distances from the helideck will be compatible with the one-engine-inoperative capability of the helicopter type to be used.

2 LIMITED OBSTACLE SURFACE - HELIDECKS

Note — Where obstacles are necessarily located on the structure, a helideck may have a limited obstacle sector.

Description. A complex surface originating at the reference point for the obstacle-free sector and extending over the arc not covered by the obstacle-free sector within which the height of obstacles above the level of the FATO will be prescribed.

Characteristics. A limited obstacle sector shall not subtend an arc greater than 150 degrees. Its dimensions and location shall be as indicated in Figure 6-2.

3 OBSTACLE LIMITATION REQUIREMENTS

Helidecks

Note — The following specifications are for helidecks located on a structure and engaged in such activities as mineral exploitation, research, or construction, but excluding heliports on ships.

3.1 A helideck shall have an obstacle-free sector.

Note — A helideck may have a limited obstacle sector (see Chapter 6 paragraph 2, Characteristics).

3.2 There shall be no fixed obstacles within the obstacle-free sector above the obstacle-free surface.


3.3 In the immediate vicinity of the helideck, obstacle protection for helicopters shall be provided below the heliport level. This protection shall extend over an arc of at least 180 degrees with the origin at the centre of the FATO, with a descending gradient having a ratio of one unit horizontally to five units vertically from the edges of the FATO within the 180-degree sector. This descending gradient may be reduced to a ratio of one unit horizontally to three within the 180-degree sector for multi-engine helicopters operated in performance class 1 or 2 (see Figure 6-1).

3.4 Where a mobile obstacle or combination of obstacles within the obstacle-free sector is essential for the operation of the installation, the obstacle(s) shall not subtend an arc exceeding 30 degrees, as measured from the centre of the FATO.

3.5 Within the 150-degree limited obstacle surface/sector out to a distance of 0.62 D, measured from the centre of the FATO, objects shall not exceed a height of 0.05 D above the FATO. Beyond that arc, out to an overall distance of 0.83 D the limited obstacle surface rises at a rate of one unit vertically for each two units horizontally (see Figure 6-2).

Shipboard heliports

Purpose-built heliports located forward or aft

3.6 When helicopter operating areas are provided in the bow or stern of a ship, they shall apply the obstacle criteria given in paragraphs 3.1, 3.3 and 3.5.

Amidships location

3.7 Forward and aft of the FATO shall be two symmetrically located sectors, each covering an arc of 150 degrees, with their apexes on the periphery of the FATO D reference circle. Within the area enclosed by these two sectors, there shall be no objects rising above the level of the FATO, except those aids essential for the safe operation of a helicopter and then only up to a maximum height of 25 cm.


Note — Examples of potential hazards include nets or raised fittings on the deck that might induce dynamic rollover for helicopters equipped with skids.

3.9 To provide further protection from obstacles fore and aft of the FATO, rising surfaces with gradients of one unit vertically to five units horizontally shall extend from the entire length of the edges of the two 150-degree sectors. These surfaces shall extend for a horizontal distance equal to at least 1 D of the largest helicopter the FATO is intended to serve and shall not be penetrated by any obstacle (see Figure 6-3).

Non-purpose-built heliports

Ship’s side location

3.10 No objects shall be located within the FATO, except those aids essential for the safe operation of a helicopter (such as nets or lighting) and then only up to a maximum height of 2.5 cm. Such objects shall be present only if they do not represent a hazard to helicopters.

3.11 From the fore and aft midpoints of the D reference circle, an area shall extend to the ship’s rail to a fore and aft distance of 1.5 times the diameter of the FATO, located symmetrically about the athwartships bisector of the reference circle. Within this sector there shall be no objects rising above the level of the FATO, except those aids essential to the safe operation of the helicopter and then only up to a maximum height of 25 cm (see Figure 6-4).

3.12 A horizontal surface shall be provided, at least 0.25 times the diameter of the D reference circle, which shall surround the FATO and the obstacle-free sector, at a height of 0.05 times the diameter of the reference circle, which no object shall penetrate.

Winching areas

3.14 The manoeuvring zone shall comprise 2 areas:

a) the inner manoeuvring zone extending from the perimeter of the clear zone and of a circle of diameter not less than 1.5 D; and

b) the outer manoeuvring zone extending from the perimeter of the inner manoeuvring zone and of a circle of diameter not less than 2 D.

3.15 Within the clear zone of a designated winching area, no objects shall be located above the level of its surface.

3.16 Objects located within the inner manoeuvring zone of a designated winching area shall not exceed a height of 3 m.

3.17 Objects located within the outer manoeuvring zone of a designated winching area shall not exceed a height of 6 m.

Application

1.1 Winching area markings shall be provided at a designated winching area (see Figure 6-5).

Location

1.2 Winching area markings shall be located so that their centre(s) coincides with the centre of the clear zone of the winching area.

Characteristics

1.3 Winching area markings shall comprise a winching area clear zone marking and a winching area Manoeuvring zone marking.

1.4 A winching area clear zone marking shall consist of a solid circle of not less than 5 m in diameter and of a conspicuous colour.

1.5 A winching circle manoeuvring zone shall consist of a broken circle of line of 0.2 m in width and of a diameter not less than 2 D and be marked in a conspicuous colour. Within it “WINCH ONLY” shall be marked to be easily visible to the pilot.

2 HELIDECK IDENTIFICATION MARKING

2.1 Recommendation — On a helideck, the size of the heliport identification “H” marking should have a height of 4 m with an overall width not exceeding 3 m and a stroke width not exceeding 0.75 m.

3 MAXIMUM ALLOWABLE MASS MARKING

3.1 Recommendation —A maximum allowable mass marking should be displayed at an elevated heliport and at a helideck.

4 MAXIMUM ALLOWABLE D-VALUE MARKING

4.1 Recommendation — The D-value marking should be displayed at an elevated heliport and at a helideck.

5 TOUCHDOWN / POSITIONING MARKING

Application

5.1 A touchdown/positioning marking shall be provided where it is necessary for a helicopter to touch down or be accurately placed in a specific position.

Location


5.2 A touchdown/positioning marking shall be located so that when the pilot’s seat is over the marking, the undercarriage will be inside the load-bearing area, and all parts of the helicopter will be clear of any obstacle by a safe margin.

5.3 On a helideck the centre of the touchdown marking shall be located at the centre of the FATO, except that the marking may be offset away from the origin of the obstacle-free sector by no more than 0.1 D where an aeronautical study indicates such offsetting to be necessary and that a marking so offset would not adversely affect the safety.

Note — It is not considered appropriate to offset a touchdown marking on a heliport located on the bow of a vessel, or for any helideck where the D-value is 16 m or less.

Characteristics

5.4 A touchdown/positioning marking shall be a yellow circle and have a line width of at least 0.5 m. For a helideck, the line width shall be at least 1 m.

5.5 The inner diameter of the circle shall be 0.5 D of the largest helicopter the TLOF is intended to serve.

5.6 When a net is located on the surface of a FATO, it shall be large enough to cover the whole of the touchdown/positioning marking and shall not obscure other essential markings.

6 HELIPORT NAME MARKING

6.1 Recommendation — The characters of the marking should be not less than 3 m in height at surface-level heliports and not less than 1.2 m on elevated heliports and helidecks. The colour of the marking should contrast with the background.

7.5 The chevron shall be marked in a conspicuous colour.

8 HELIDECK SURFACE MARKING

Characteristics


8.1 Recommendation — The helideck surface bounded by the FATO should be of a dark colour using a high friction coating. Where the surface coating may have a degrading effect on friction qualities, it may be necessary to leave the helideck surface untreated. In such cases, the conspicuity of the markings should be enhanced by outlining the deck markings with a contrasting colour.

9 HELIDECK PROHIBITED LANDING SECTOR MARKING

Application

9.1 Recommendation — Helideck prohibited landing sector marking should be provided where it is necessary to prevent the helicopter from landing within specified headings.

Location

9.2 Recommendation— The prohibited landing sector markings should be located on the touchdown/positioning marking to the edge of the FATO, within the relevant headings as shown in Figure 7-1.

Figure 7-1 Helideck prohibited landing sector marking


CHAPTER 8 – AERONAUTICAL LIGHTS


Note — In the case of helidecks and heliports located near navigable waters, consideration needs to be given to ensuring that aeronautical ground lights do not cause confusion to mariners.

1 TOUCHDOWN AND LIFT-OFF AREA LIGHTING SYSTEM

Application

1.1 The TLOF lighting system for an elevated heliport or helideck shall consist of:

a) perimeter lights; and

b) ASPSL and/or LPs to identify the touchdown marking where it is provided and/or floodlighting to illuminate theTLOF.

Note — At elevated heliports and helidecks, surface texture cues within the TLOF are essential for helicopter positioning during the final approach and landing. Such cues can be provided using various forms of lighting (ASPSL, LP, floodlights or a combination of these lights, etc.) in addition to perimeter lights. Best results have been demonstrated by the combination of perimeter lights and ASPSL in the form of encapsulated strips of light emitting diodes (LEDs) to identify the touchdown and heliport identification markings.

Location

1.2 TLOF perimeter lights shall be placed along the edge of the area designated for use as the TLOF or within a distance of 1.5 m from the edge. Where the TLOF is a circle the lights shall be:

a) located on straight lines in a pattern which will provide information to pilots on drift displacement; and

b) where a) is not practicable, evenly spaced around the perimeter of the TLOF at the appropriate interval, except that over a sector of 45 degrees the lights shall be spaced at half spacing.

1.3 TLOF perimeter lights shall be uniformly spaced at intervals of not more than 3 m for elevated heliports and helidecks. There shall be a minimum number of four lights on each side including a light at each corner. For a circular TLOF, where lights are installed in accordance with 1.2 b) there shall be a minimum of fourteen lights.

Note — Guidance on this issue is contained in the Heliport Manual (Doc 9261).

1.4 The TLOF perimeter lights shall be installed at an elevated heliport or fixed helideck such that the pattern cannot be seen by the pilot from below the elevation of the TLOF.

1.5 The TLOF perimeter lights shall be installed at a floating helideck, such that the pattern cannot be seen by the pilot from below the elevation of the TLOF when the helideck is level.

1.6 Recommendation— When LPs are used on an elevated heliport or helideck to enhance surface texture cues, the panels should not be placed adjacent to the perimeter lights. They should be placed around a touchdown marking where it is provided or coincident with heliport identification marking.

2 WINCHING AREA FLOODLIGHTING

Application

2.1 Winching area floodlighting shall be provided at a winching area intended for use at night.


Location

2.2 Winching area floodlights shall be located so as to avoid glare to pilots in flight or to personnel working on the area. The arrangement and aiming of floodlights shall be such that shadows are kept to a minimum.

Characteristics

2.3 The spectral distribution of winching area floodlights shall be such that the surface and obstacle markings can be correctly identified.

2.4 Recommendation — The average horizontal luminance should be at least 10 lux, measured on the surface of the winching area.


CHAPTER 9 – RESCUE AND FIRE FIGHTING FACILITIES

Note – Reference shall also be made to CAAP 70.

1.1 This Chapter refers directly to UK CAP 437 (Chapter 5); it sets out the requirements regarding provision of equipment, extinguishing media, personnel, training and emergency procedures for off-shore helidecks on installations and vessels.
