Define a rapid exit taxiway
A taxiway connected at an acute angle and designed to allow aeroplanes to turn off at higher speeds than are achieved on other exit taxiways and thereby minimising runway occupancy times.
Define taxiing
Movement of an aircraft on the surface of an aerodrome under its own power other than take-off and landing
Define an apron
A defined area, intended to accomodate aircraft for purposes of loading or unloading passengers, mail or cargo, parking or maintenance

That part of an aerodrome to be used for the take-off, landing and taxiing of a/c, excluding aprons
Define a movement area
That part of an aerodrome to be used for the take-off, landing and taxiing of a/c, consisting of the manoeuvring area and the aprons
Define a non-instrument runway
A runway intended for the operation of a/c using visual approach procedures
Define an instrument runway
Runway either non-precision or precision using instrument approach procedures
Define a non-precision instrument runway
An instrument runway served by visual aids and a non-visual aid providing at least directional guidance adequate for a straight in approach.
Define a precision approach runway
An instrument runway intended for the operation of a/c using precision approach aids that meet the facility performance requirements defined in ICAO Annex 10 appropriate to the categories of ops
Define a hotspot
A location on an aerodrome movement area with a history or potential risk of collision or runway incursion, and where heightened attention by pilots/drivers is necessary.
Define a runway strip
An area enclosing a runway or any associated stopway
Reduces risk of damage to a/c running off the runway by providing graded (smoothed) area meeting specified longitudinal, transverse slope and bearing strength requirements
What does the strip contain on a precision/instrument runway?
The LDA
What does the strip contain on a non-instrument runway?
Narrower strip encompasses the ASDA
Is take-off an instrument procedure?
No it is a visual one
Define a clear and graded area
An area within the runway strip whose dimensions are determined by the function of the strip within which it lies.
Only obstacles which are small and frangible and will not aggravate the consequences of an aircraft ground swing are allowed in the area.
What are the typical dimensions of a runway strip and the clear and graded area?
What determines the required taxiway width?
The type of a/c using them
For which a/c does a ACR/PCR apply?
A/C with a MTOM greater than 5700kgs
Define the stopway
A defined rectangular area on the ground at the end of the TORA prepared as a suitable area in which an a/c can be stopped in the case of abandoned take-off.
Define the clearway
A defined rectangular area under the control of the appropriate entity, selected or prepared as suitable area over which an aeroplane may make a portion of its initial climb to a specified height.
Define a starter extension
Area at the start of a runway for the commencent of an a/c’s take-off
Define the RESA
Runway End Safety Area
An area intended to minimise the risks arising when an aeroplane overruns or undershoots a runway
Define the TORA
Take-Off Run Available
The length of the runway available and suitable for the ground run of an aeroplane taking off. In most cases it will correspond to the length of the runway pavement
Define the TODA
Take-Off Distance Available
The TORA + the length of any associated clearway
Define the ASDA
Accelerated Stop Distance Available
TORA+ any associated Stopway
Define the LDA
Landing Distance Available
The length of the runway available and suitable for the ground landing of an a/c
With regards to tall structures how must obstacle lights be arranged?
One red light at the top with other red lights displayed for every 45m of height (evenly spaced)
With regards to large structures how must obstacle lights be arranged?
Vertically, each end of large buildings is lit above, with additional red lights displayed horizontally and uniformly for every 45m of lateral dimensions
What does Aerodrome Ground Lighting Provide a pilot with?
Alignment
Roll Guidance
Limited distance to go
What is the definition of a Cat I Precision Approach Runway?
An instrument runway served by non-visual aids and visual aids
Ops with DH no less than 200ft
& vis not less than 800m/RVR not less than 500m
What is the definition of a Cat II Precision Approach Runway?
An instrument runway served by non visual and visual aids
Ops with DH lower than 200ft but not lower than 100ft and a RVR not less than 300m
What is the definition of a Cat III Precision Approach Runway?
An instrument runway served by non visual and visual aids
Ops either;
- DH <100ft, or, no DH and RVR not less than 175m
- DH <50ft, or, no DH and RVR less than 175m but greater than 50m
- No DH and no RVR limitations
What is the definition of a non-precision approach runway?
An instrument runway served by visual aids and a non-visual aid providing at least directional guidance adequate for a straight in approach
What sort of runways with instrument approaches must also have lighting?
All of them
What type of lights must a non-precision approach have?
Low Intensity
Standard 1 Bar Approach System
Standard 5 Bar Approach System
Standard 5 Bar Approach System for a CAT II/III runway
Standard CAT I Runway Lighting
Standard CAT II/III Runway Lighting
What do Approach Slope Indicators provide to a pilot?
Achieved approach angle
Clearance over approach obstacles
Limited roll guidance
When must an aerodrome provide an Aerodrome Beacon?
A/C navigate at night by visual means
Red vis is freqeuent
It is difficult to locate the aerodrome from the air due to surrounding lights or terrain
What colour will aerodrome beacons be?
White flashes/ white and coloured flashes alternating
Land=green
Water=yellow
What colour are taxiway lights?
Green centreline
Blue edge
Reflective markers may be used in lieu of lights
Edges of turning and holding areas will also be blue
When must AGL be displayed?
By day;
vis less than 5km and/or the cloud base less than 700ft
By night;
irrespective of weather conditions
How will lighting faults be reported?
In the form they have been passed to you by the pilot.
Do not assume that any particular defect renders an aid unservicable
The pilot is responsible for determining course of action
Record the details on the appropriate form or log and disseminate in accordance with unit instructions
