Day 1 Flashcards
What does the MATS 1 contain?
Procedures instructions and info which are intended to form the basis of ATS in the UK
Define ATC unit
a place from which instructions (ATC Service) and advice (ATAS) are given by radio to a/c in the interests of safety.
Define ATSU
The term ATSU is used when it is significant that the instruction applies to AFIS unit or A/G comms service unit in addition to an ATC unit.
What is an SI when is it issued?
Supplementary Instruction
Issued to introduce an entirely new subject or a radical change to existing procedures,
to introduce time critical changes when the routine quarterly amendment cycle does not suffice
To re-emphasize an existing instruction
UK AIP consists of.

What is CAP 168
Licensing of Aerodromes
Sets out minimum standards at airports
Define Aerodrome
An area of land or water, designed, equipped, set apart or commonly used for affording facilities for the landing or departure of aircraft
Define Runway
A defined rectangular area on a land aerodrome prepared for the landing and take off run of aircraft along its length
Define RWY Threshold
Beginning of that portion of the runway useable for landing
Define Taxiway
A defined path on a land aerodrome established for the taxying of a/c and intended to provide a link between one part the aerodroma and another.
Define aircraft stand taxilane
Portion of an apron designated as a taxiway and intended to provide access to aircraft stands only
Define apron taxiway
A portion of a taxiway system located on an apron and intended to provide a through taxi route across the apron
Define Apron
The part of an aerodrome provided for the stationing of aircraft for the embarkation and disembarkation of passengers, the loading and unloading of cargo and parking.
Define manoeuvring area
The part of the aerodrome provided for the t/o and landing of a/c and for the movement of a/c on the surface EXCLUDING the apron and maintenance area
Define movement area
The part of the aerodrome intended for the surface movement of a/c INCLUDING the man area, apron, maintenance area
ARP
Aerodrome reference point - geographical location of aerodrome and centre of the ATZ.
WIP given as a bearing and distance from the ARP
Define NON instrument runway
A RWY intended for the operation of A?C using visual app procedures
Define instrument RWY
A RWY intended for the operation of a/c using NON VISUAL aids providing at least direction guidance in azimuth adequate for a straight in approach
Precision instrument APP RWY
An instrument rwy intended for the operation of a/c using precision instrument app aids that meet the requirements for that Cat of ops
A?C has electronic instrumented guidance in azimuth and glideslope
Non Precision App RWY
An instrument RWY served by visual aids and non visual aids providing at least directional guidance adequate for a straight in app.
Aerodrome reference code
Element 1
Number determined by selecting the higher of the TODA or ASDA
4 is 1800m and over
Aerodrome reference code
Element 2
letter which corresponds to the wingspan or outer main gear wheel span whichever is more demanding of the largest a/c likely to operate at an aerodrome
E wingspan 52m up to but not icluding 65M or Wheel span 9m up to but not including 14m
F above the figures for E
Minimum rwy width for 4E
45m
Runway surfaces
Principle requirements
Provide sufficient surface friction level
Provide a hard and durable surfsce that will not generate loose materials or contaminents
Provide good surface water drainage
Provide a suitable PCN
Avoid excessive tyre wear
Types of RWY SFC
Porous friction course
Pavement quality concrete
Asphalt (grooved)
Define Starter extension
Where additional runway distances are required for take off these may be achieved by adding a starter extension to the beginning of the runway.
Normally full width but provided the length is not more than 150 m its width may be reduced to not less than 2/3
Define turning area
Where the end of the RWY is not served by a taxiway a rwy turn pad should be provided to facilitate a 180 degree turn
define runway shoulder
An area adjacent to the edge of a paved surface so prepared as to provide a transition between the pavement and the adjacent surface for a/c running of the pavement
Runway shoulders should….
Be provided for rwys where the code letter is D or E unless width is already 60m or more
Extend symmetrically on each side of the rwy so that the overall width of the rwy plus shoulders is not less than 60m
be capable of supporting aeroplanes using the rwy without causing structural damage
Define RWY strip
an area of specified dimensions enclosing a rwy intended to reduce the risk of damage to an a/c running off the rwy and to protect a/c flying over it when t/o and landing
The purpose of the Rwy strip is to…
A) reduce the risk of damage to an aeroplane running off the rwy by providing a graded area which meets specified logtiduninal and transverse slopes and bearing strenght requirements
B) protect aeroplanes flying over during landing and t/o by providing an area which is cleared of obstacles except permitted aids to navigation
RWY strip permitted aids
Must be frangible
Height must be kept to min necessary for the particular site and function of the equipment
if in the CGA not more than 0.9M AGL and not closer than 15M from the rwy edge
App lights / PAPIs/ ILS glidepath
RWY Strip dimensions for Cat 4 instrument RWY
Rectangle
150m either side of centreline
60m from either side of RWY
Define CGA
Provides a delethalised area - minimal damage to an a/c in the event of leaving the rwy
Nothing apart from essential equipment allowed
Dimensions determined by CAP168
Different widths for precision and non-precision rwy
Must be capable of supporting the a/c using the rwy
All rwy holding points are located outside the CGA
Wessex CGA 26/08
105m eith side of rwy centreline
60m from each end of rwy
from the 60m point first 150 M is 75m wide each side of extended centreline
next 150m the width extends from 75m to 105m
Define stopway
A stopway is an area on the ground beyond the TORA which is prepared and designated as a suitable area in which an a/c can be stopped in the event of an abandoned t/o
Designated for infrequent use
Strong enough to support an a/c using the rwy
Should be the same width as the rwy
Define Clearway
An area at the end of the TORA selected or prepared as a suitable area over which an aircraft may make a portion of its initial climb to a specified height.
Provide s and area over which an a/c can safely transit from lift off to full climb rate after t/o which is free from obstacles which may cause a hazard to a/c in flight.
It may be outside the a/d boundary over land or water
