Executive Summary

AECOM have completed the Obstacle Limitation Surface (OLS) survey for Cassidy International Airport (CXI) and

have compiled the Type A charts for the take-off climb surface for departure runways 08 and 26 to both ICAO

geometric standards.

The departure take-off climb surface is normally the critical performance consideration for aircraft operations.

The aircraft has to accelerate from a standstill to take-off speed then climb out over potential obstacles past the

end of the runway strip. In comparison, on approach the aircraft overflies potential obstructions on its way to

touching down on the runway (part way along the runway surface). On the aircraft approach, issue with regards to

strip width are an important consideration.

The Type A chart is intended to advise both aircraft operators and the Airport Authority of potential take-off flight

path obstructions which may impact on the aircraft performance considerations, and depending on the location

and height of the obstruction these may also need to be notified in the Aeronautical Information Publication (AIP)

for the airport. The Type A chart is also used by the airport operator to actively manage obstructions, such as

trees which increase in height over time, and to limit the height of future construction works to be below the critical

surface levels.

The AIP also provides a table which relates to the runway length available in relationship to the take-off and

approach surfaces. This allows pilots to gauge if terrain obstructions are occurring. The existing published table

will require significant amendment if the observed obstructions are not attended to.

The OLS survey also considers and presents the aircraft arrival profile, the runway strip and runway strip

transitional side slope profiles. AECOM have prepared a separate approach – runway strip OLS plan for

Cassidy. This is necessary as it provides additional information required to be considered in the overall aircraft

flight envelope from an operational safety perspective.

Currently clearways are provided at each runway end, this makes the departure slope clearance significantly

more onerous than the approach path. Having clearways allows heavier departure take-off weights to be

achieved from Cassidy’s runway length.

Due to the predominant wind orientation, runway operations are typically approach to and departure from runway

08. Aircraft typically makes land fall over London town and overfly the atolls terrain immediately to the west of

the 08 runway on approach and departs out over the sea when climbing away from the 26 threshold.

Update AIP Data

The established positions and heights (feet amsl) for the main AIP references points for the runway are as follows:

Type A Charts and Obstruction Data Sheets

The Type A charts and obstruction data tables are attached in Appendix B.

Approach OLS Plan and Section views and data sheets

The Approach OLS charts and obstruction data tables are attached in Appendix C.

Obstruction Clearance Works

We recommend that palm tree obstructions are removed and other vegetation is cut back to the 1.6% gradient

limitation for both runways.

Runway 08 departure / runway 26 approach

Runway 08 Departure obstructions are relatively minor and comprise several low level palms and bushy scrub in

the outer strip extents. These minor obstructions should be cleared to provide an unobstructed 08 departures or

26 runway approaches with minimal effort.

Runway 26 departure / runway 08 approach

There are two groups of palms in the outer runway strip in the 08 end area that require removal as a first priority.

Runway 08 approach – palm clearance at strip end Runway 26 approach – scrub clearance

Runway 08 approach – palm plantation

The 08 approach and 26 departure runway has

significant obstructions beyond the runway strip end

area including a palm plantation to the west of the

runway which borders onto the Banana Village.

These obstructions penetrate through the critical 2%

obstacle limitation surface for both departure and

approach surfaces and mainly comprise mature palms

and other trees. The clearance work for the approach

surface may extend up to the Banana village area. We

recommend that a field survey be implemented and

tree’s close to the village area are paint marked with

the 2% limitation level and the 1.6% preferred trimming

level to gauge potential local impacts. Even though the

plantation is potentially on government owned land,

prior to any clearance being undertaken, consultation

with local village elders is recommended.

On the very western edge of the approach surface is a tall communications mast which extends approximately

20m through the edge of the approach OLS surface, this tower is located on the edge of the Banana village and

would provide a useful local reference for siting on the ground the lateral limits for tree clearance works. This

tower will require obstruction lighting to be installed.

Recommended Next Steps

In summary the following actions are recommended:

1) The runway ends, ARP and Navigational aids details are to be provided to Airways International for updating

in the AIP publication data.

2) A number of additional tall masts have been identified and should also be added onto the AIP charts via

Airways Internationals AIP publication service.

3) Two groups of trees located in the outer extents of the runway strip at the 08 end area are required to be

removed as soon as practical.

4) The 08 Departure runway is the predominant take-off operation. There are close in scrub and tree

obstructions at the 26 runway end. We recommend that these palm and scrub obstructions be removed as

soon as possible; this should be a relatively simple clearance exercise. Once this clearance is completed,

the Type A Chart can be updated for the 08 departure runway as being obstruction free.

5) A more rigorous tree clearance program is required for the 26 departures / 08 approach runway:

a) This will include removal of a significant number of plantation trees to the west of the 08 runway end

and may encroach up to the Banana village area.

b) Whilst this plantation is located on Government land, consultation with the local Banana village

representatives is recommended.

c) A field survey to mark trees with the required clearance levels adjacent to the village is recommended

to gauge potential impacts of the proposed clearance works.

6) Once the tree clearance work has been completed on both runway ends, a check survey should be

implemented and a revised type A chart then issued for formal publication.

7) Once the Type A chart is published there is an obligation to resurvey every 3 to 5 years to monitor tree

growth, check for new obstructions and actively maintain obstruction clearances.

1.0 Introduction

1.1 Terms of Reference

In accordance with the PAIP development objective to improve aviation infrastructure safety and security

compliance, it is expected that the participating airports will undergo aerodrome certification as a result of the

improvements financed under PAIP.

Safety oversight for each participating country is conducted in accordance with the New Zealand Civil Aviation

Rules (NZCARs) and accordingly, this study is required in order that each aerodrome may comply with the

requirements of NZCAR Part 139.51 and part 139.125 as reproduced below1:

NZCAR 139.51 Aerodrome design requirements

a) An applicant for the grant of an aerodrome operating certificate must ensure that the physical characteristics

of the aerodrome; the obstacle limitation surfaces; the visual aids for navigation and for denoting obstacles

and restricted areas; and the equipment and installations for the aerodrome are commensurate with the

following:

1) The characteristics of the aircraft that the aerodrome is intended to serve.

2) The lowest meteorological minima intended for each runway.

3) The ambient light conditions intended for the operation of aircraft.

NZCAR 139.125 Unsafe Conditions

a) Each holder of an aerodrome operating certificate shall establish procedures for restricting aircraft

operations where an unsafe condition exists on an aerodrome.

b) The procedures shall ensure that operations are not conducted on portions of the aerodrome where such an

unsafe condition exists.

Aerodromes in Kiribati and Tuvalu will be expected to undergo aerodrome certification as a result of the PAIP

investments, including undertaking an OLS study and design of GNSS approaches. Tonga has recently

completed an OLS with associated GNSS approaches, and is currently certified against the Tongan equivalent of

NZCAR Part 139, however Kiribati and Tuvalu have not yet gone through this certification process.

OLS surveys, Analysis of Requirements and GNSS approaches are required for all aerodromes participating in

PAIP. Some airports have had some work undertaken already but not all airports require the same scope of

services. Partial OLS and RNAV approaches have been conducted at Bonriki International Airport in Kiribati, and

an OLS and RNAV approach has been undertaken at Funafuti International Airport in Tuvalu. These shall be

reviewed and expanded upon as necessary, as part of this assignment.

The Republic of Kiribati and Tuvalu follow the standards, recommended practises and procedures that have been

adopted by ICAO. As such, ICAO Procedures for Air Navigation Services — Aircraft Operations (PANS-OPS, Doc

8168) Volume II, Part 1, Section 2, Chapter 4, Quality Assurance), requires that the State take measures to

“control” the quality of the processes associated with the construction and review/quality assurance of instrument

flight procedures. Review of each instrument procedure will be required as part of this assignment.

1.2 Scope of Services – extracted from TOR

The detailed scope of services to be provided shall be undertaken at each participating airport: Cassidy

International Airport (Kiribati), Bonriki International Airport (Kiribati), and Funafuti International Airport (Tuvalu), as

indicated and shall include:-

Part A – Obstacle Limitation Survey

a) Review of existing OLS, RNAV, GPS and GNSS Approaches for Bonriki International Airport, Kiribati, and

Funafuti International Airport, Tuvalu.

1 National legislation exists in each country based on the NZCARs. This assignment shall be conducted against the domestic

equivalent of these NZCARs.

AECOM

b) Undertake an Obstacle Limitation Survey (OLS) in consideration of the current operational and design

aircraft for each aerodrome. This shall include development, or review and updating of existing information

as applicable:

i) Convert all aeronautical geographical coordinates into the WGS-84 geodetic reference datum.

ii) Establish an Aerodrome Reference Point (ARP) in WGS-84.

iii) Establish runway ends, threshold points for each runway, in WGS-84 and elevations.

iv) Establish runway length and declared distances.

v) Establish runway strip dimensions and options for RESA.

vi) Establish Runway Direction and Magnetic Declination.

vii) Establish positions and heights of all obstacles infringing the appropriate OLS for each aerodrome as

required under ICAO Annex 14 (that includes obstacle penetration through the visual slope segment of

runways’ approaches).

viii) Produce an Aerodrome Obstacle Chart – ICAO Type A (Operating Limitations).

ix) Establish pre-flight altimeter check location at apron.

x) Establish location, coordinates and height of air navigation aids.

Part B – Analysis of Requirements for Operating and Design Aircraft, and Development of Supporting

Material

a) Based on the OLS survey and activities undertaken in Part A of this assignment, prepare an Analysis of

Requirements for the operating and design aircraft for each aerodrome taking into consideration compliance

issues with ICAO Annex 14, and NZCAR Part 139.

b) Identify issues arising from the Analysis above.

c) Develop risk mitigation measures to address the Analysis and identified Issues per (a) and (b) above.

d) Develop supporting documentation such as ICAO Type A charts, topographical charts etc for each

aerodrome.

e) As part of “control of the quality of the process” a review of each instrument procedure at the Cassidy,

Bonriki and Funafuti Airports is to be completed. This will involve:

i) a complete planned systemic review according to ICAO standards and recommended practises on the

existing airspace procedures.

ii) review of all instrument procedures at the airports above, following and adhering to all ICAO

practises/guidelines to include (but not limited to) all procedure design processes reviewed against

PANSOP’s criteria changes to ensure compliance, updated with new obstacle/surveyed data, terrain,

procedure design documentation, calculations, verification and validation methods, safety and

efficiency recommendations, any deficiencies noted and qualify the acquisition/processing of source

information/data.

There are 4 procedures for each airport to be reviewed and reported on (12 procedures in total to be

reviewed) plus likely updates to each of the three airports published data as a result of the review findings

and recommendations.

f) Develop a full Procedure Design Report (PDR) will be issued outlining the results of the airspace procedure

review in part (e) above.

In undertaking this assignment, the Consultant will be expected to review existing OLS, RNAV, GPS and GNSS

Approaches for Bonriki International Airport, Kiribati, and Funafuti International Airport, Tuvalu.

In addition, the Consultant will be directed by the relevant government airport operator, and will be expected to

liaise closely with relevant stakeholders, such as the airlines currently servicing the airports.

3.0 Aerodrome Data

3.1 Aerodrome Reference Point – ARP

Aerodrome Reference Point (ARP) is the declared position of the airport which is then used to calculate specific

components of the runway OLS. The position of the ARP is provided in the AIP.

The ARP at Cassidy International Airport consists of a tube set in concrete with a marker pin and is located in the

northern flank of the runway strip around the mid runway distance.

Figure 3-1 Close up of the ARP benchmark Figure 3-2 Location of the ARP benchmark relative to the runway

Table 3.1 shows the position of the ARP in WGS84 coordinates and ellipsoidal heights calculated using GPS

observations. The orthometric height is calculated through a level survey linking the ARP and Runway End Points

to the local survey Benchmarks at the airport.

(m) Orthometric Height

ARP 1° 59’11.661” N 157° 21’06.890” W 24.099 2.860

The current ARP is published as the mid runway point, and listed as 1° 59’28” N 157° 21’ 1” W, this will need to

be updated with the information in Table 3.1.

3.2 Runway End Points

Table 3.2 shows the position of the runway threshold end points in WGS84 coordinates and ellipsoidal heights

calculated using GPS observations. The orthometric height is calculated through a level survey linking the ARP

Figure 3-4 Threshold 26 Runway End Point

3.3 Runway Declared Distances

The runway has a measured length of 2102.97m; this has been rounded off to 2103m.

This is the measurement between the two threshold pins and is the declared distance for Take Off Run Available

(TORA), Accelerated Stop Distance Available (ASDA) and Landing Distance Available (LDA).

Currently the published AIP for Cassidy includes 150m clearways, and as such the Type A inner edge should be

moved out to that position rather than the default 60m strip edge position.

The Take Off Distance Available (TODA) also includes the clearway dimension when this exceeds the strip end

width dimension, interim declared lengths are shown in Table 3.3.

Table 3.3 Runway Declared Distances

Accelerated Stop Distance Available (ASDA) 2103 m 2103 m

Landing Distance Available (LDA) 2103 m 2103 m

The runway nominal width is 30m with 7.5m structural shoulders for a total sealed width of 45m.

3.4 Runway Strip and RESA Dimensions

The strip width is nominally 300m and is in general accordance with ICAO Annex 14 recommendations.

The runway strip end includes structural pavement that extends through to the RESA extents for a total length of

150m (60m strip end + 90m RESA) at each runway end.

There are four tall masts, one immediately south of the runway (in close proximity to the NDB and DME masts)

and which intrudes through the runway transitional side slope. One in close proximity to the 08 approach runway

surface, and a further two located at some distance east of the airfield.

4.0 Obstacle Limitation Surfaces

4.1 Limitation Surfaces Details

OLS are theoretical boundaries surrounding a runway that provide a safe passage for aircraft to operate. There

are two main parts of OLS: approach/departure slopes which consist of slopes starting at the end of the runway

strip (otherwise known as the inner edge) and transitional surfaces extend up from the edge of the runway strip

until meeting the horizontal surface and conical surfaces. Refer Figure 4-1 for a cut through diagram showing the

various surfaces.

Figure 4-1 Obstacle Limitation Surface

For the approach OLS, the following dimensions and slopes have been adopted:

Table 4.1 Runway Approach OLS dimensions and slopes

Surface Measurement type ICAO Table 4-1 AC139-06 Table 4-1

Conical Slope 5% (=1:20) 1:20

Height above ARP 45 m + 75m 150 m

Inner Horizontal Height above ARP 45 m 45 m

Locus from strip edge 4000 4000

Approach Width (inner edge) 300m 150 / 300m

Distance from Threshold 60 m 60 m

Divergence each side 15% (=1:6.6) 1:6.6

Length 15,000m 15,000m

Slope 2% (=1:50) 1:50

Transitional Slope 14.3% (=1:7) 1:7

As can be seen, there is a variance in the height of the upper conical surface between ICAO and NZ CAA

advisory (120m vs 150m). For the upper conical OLS surfaces, we have assumed the more onerous NZCAA

height requirement.

The NZ Advisory Circular does allow consideration of a 150m inner edge width. Given the international

emergency alternate status of CXI, AECOM have presented the more onerous 300m approach width profile for

the approach OLS.

The take-off surfaces utilise the dimensions and slopes detailed in Table 4.2, as can be seen both ICAO and NZ

CAA requirements are identical in this instance.

*At CXI a 150m clearway is currently published in the AIP, this moves the inner edge position to 150m past the runway

threshold point.

**1800m when the intended track includes changes of heading greater than 15º for operations conducted in IMC, VMC by night

Approach and take off surface configurations are shown in Figures 4-2 and 4-3.

4.2 Type A Charts

The Type A Chart requires obstacles above 1.2% to be recorded for an ongoing monitoring purposes. This is

especially important for trees which increase in height with time.

AECOM has added the 1.6% surface level into the Type A Tables for reference. Often, trees are trimmed back to

the 1.6% level in accordance with the recommendation presented in ICAO Annex 14, AC 139-06 and AC 139-10

for obstacle control. We note that palms, due to the growth point being at the crown, do not survive when topped.

Accordingly, palms should be cut back to ground level when these intrude into the OLS surfaces.

5.0 Type A Chart Tables

Since CXI has runway end clearways, the departure slope obstacle clearances are more onerous than the

approach OLS slope profile.

Due to the prevalent wind direction being westward, the primary approach and departures are on the 08 runway

for the vast majority of flight operations.

5.1 Take-Off Obstacles Departure Runway 08

Departure runway 08 to the east has only minor scrub and tree intrusion. Tree intrusions are towards the outer

edges of the runway strip extents. Clearance of the obstructions should be undertaken, this would allow the Type

A chart to be updated and presented as free of obstructions. A general view from the 21 threshold is presented in

Figure 5-1. Vegetation should be removed from the clearway / RESA formation strip areas and immediately

beyond. Refer Figure 6-2 for an aerial view.

5.2 Take Off Obstacles Departure Runway 26

There are a number of mature palm trees which are now an obstruction to the runway take-off surface. There is

a significant plantation to the west of the extended centreline as shown below. The tall tower observable denotes

the lateral edge of the wider approach path slope.

6.0 Approach Obstacles

6.1 Runway 08 Approach

In addition to the extensive clearance work needed in the palm plantation to the west of the runway, refer Figure

5-2,on approach to runway 08 there are a number of palm tree intrusions within the strip end area. These need

to be removed as a priority as soon as possible, refer Figure 6-1 for details.

6.2 Runway 26 Approach

As can be seen from Figure 6-2, apart from minor low level scrub removal close to the runway strip end, there are

no significant obstructions to the runway 26 approach.
