Aerodrome Survey
The Aerodrome Survey has been undertaken by SLC Associates who have certified
that all the data contained within conforms to the specifications contained in
Eurocontrol Standard Document 007-97 “Surveying of Navigation Facilities” and
CAP232 “Aerodrome Survey Requirements”
The latest version was undertaken in February 20131 and copies of the full Survey
Report (February 2013) has been lodged with CAA ASD.
A hard copy is available for inspection in the Control Tower.

Runways - Declared Distances
Data giving elevations at the beginning and end of each Declared Distance is held
within the aerodrome survey.
There are two licensed runways marked on the Aerodrome.

Operating with reduced runway distances can affect operational safety margins.
Having the benefit of two runways, Haverfordwest Aerodrome is better equipped to
maintain a degree of business continuity in the event of a runway blockage than is a
single runway airport.
For this reason, and the above consideration, re-declaration and continued use of a
blocked runway will not normally be considered. Where under exceptional
circumstances a re-declaration is considered necessary the procedure outlined in
Appendix 3D will be followed.

SECTION 3 AERODROME CHARACTERISTICS
Protected Area and Slopes
The area around the runways have protected surfaces within which no obstacles are
permitted. These areas are referred to as protected areas and protected slopes.
Runway Strip
The runway strip is the area enclosing the runway the purpose of which is to provide
a graded area clear of all obstacles except permitted aids to navigation to protect
aircraft inadvertently running off the runway, or flying over during landing or take off.
The runway strip for a Code 2 runway extends 60m beyond each end of the runway
and 28m from each runway edge.
Take-off and climb / approach surfaces
These surfaces begin at the end of the runway strip and extend away along the
centreline for a distance of 2,500m, diverging by 10% each side of the extended
centreline. The gradient slope of the surfaces is 1:25. No obstacles are permitted to
penetrate these surfaces.
Transitional Slope Surfaces
These surfaces consist of a plane beginning at ground level along the edges of the
runway strip and increasing in height with increasing distance away from the strip
edge and at right angles to the runway centreline until it reaches a height of 45m.
The gradient slope is 1:5 (20%). All buildings, structures and parked aircraft must
remain below this gradient.
Figure 3-3 - Transitional Slope Clearance
EXAMPLE: An aircraft with a maximum height of 3m must be parked at least 43m
[28 + (5 x 3)] from the runway edge.
Inner Horizontal Surface
The inner horizontal surface is a horizontal plane located 45m above the lowest
runway threshold elevation and extends (for Code 2 Visual runway) to 2,500m radius
of the mid-point of the main runway.
It represents the level above which consideration needs to be given to the control of
new obstacles and the removal or marking of existing obstacles and its purpose is to
ensure safe visual manoeuvring of aeroplanes in the vicinity of the aerodrome.

APPENDIX 3D – Reduction of Declared Distances (Temporary Obstructions)
It is the responsibility of the Senior Person On Duty to ensure that pilots are notified
of the existence of all temporary obstacles within a runway strip or RESA which may
project above the approach or take-off slopes.
Such obstacles may well affect the published Declared Distances and in this event it
is the responsibility of the Senior Person On Duty to calculate the revised Declared
Distances which will then be passed on to pilots by R/T and notified by NOTAM.
CAA Directorate of Aerodrome Standards is to be notified as soon as possible.
Normally the intention to erect such an obstacle will be pre-planned and CAA DAS
will be consulted before work commences.
Temporary obstacles caused by disabled aircraft or vehicles which cannot be
removed immediately will necessitate quick action if incoming aircraft are not to be
held or diverted or outgoing aircraft held on the ground. The following procedure is to
be carried out:
•
Plot the position of the obstacle on the Aerodrome Plan.
•
An obstacle outside the Runway Strip will not require revision of the Declared
Distances.
•
An obstacle within the Runway Strip will require a revision of the Declared
Distances.
•
Calculate the position of the Revised Runway Threshold for the Threshold
nearest to the obstacle.
•
Calculate the Revised Declared Distances in relation to the Revised Runway
Threshold.

Revised Runway Threshold
To obtain the position of the Revised Threshold, multiply the height of the obstacle
by 25 and add 60m. The net displacement will be this calculated distance (“x”) added
to the measured distance (“y”) from the existing threshold position to the obstacles
highest point (see Figure 3-4 below).

Temporary displaced thresholds are to be marked with wing bars using standard bad
ground markers.
The Revised Declared LDA when landing over an obstacle will only be valid when
the final approach can be visual. APAPIS will be switched off when a displaced
threshold is in use.
At night landings over the obstacle will not be permitted until CAA DAS has been
consulted. Except in an emergency, temporary APAPIS positioned for use at the
displaced threshold and illuminated wing bars will be a minimum requirement.
