Introduction
Introduction

On RAF Airfields all movements of aircraft, both on the ground and in the air are monitored by Air Traffic Control (ATC)


The control tower
The Control Tower

Is always in a prominent position in the aircraft manoeuvring area

Houses electronic & radio equipment and may also have a Bird Control Unit


The control tower1
The Control Tower

The size & design of ATC Towers varies considerably.


Aerodrome controller
Aerodrome Controller

Is in charge of movements:

On the Ground

In the Air

Sometimes Called:

Airfield Controller

Local Controller


Approach controller
Approach Controller

They control aircraft:

departing the airfield

making instrument approaches

Uses RADAR displays, RT and landline communications


Runway controller
Runway Controller

For more effective control a Runway Controllermay be used:

  • At airfields with lots of take-offs and landings

  • They are in direct contact with Aerodrome Controller


Runway controller1
Runway Controller

The Runway controller can refuse aircraft permission to move onto the runway, land or take-off in some circumstances


Runway controller2
Runway Controller

For example they might:

  • Prevent an aircraft from landing with its undercarriage retracted by firing a RED flare.

  • Stop an aircraft from taking-off which had for example a panel unlocked or a fuel leak, by showing a steady RED on the signalling lamp.


Runway controller3
Runway Controller

  • Warn vehicles or aircraft on the ground to move clear of the landing area, by showing RED flashes on the signalling lamp.

  • Give permission to take-off, with a steady GREEN on the signalling lamp.


Communication systems
Communication Systems

Good Communications are essential to Air Traffic Control


Communication systems1
Communication Systems

Swift and accurate contact is achieved through the use of:

  • Special Telephones

  • Tele-Talk Systems

  • Radio Telephony (RT) (Ground To Air)

    • Uses VHF and UHF to talk to aircraft and vehicles.

    • These frequencies provide clear lines of communications.

    • Each airfield and its section have their own frequencies.


Visual communications
Visual Communications

  • Stationary Object Hazard

  • Bad Ground Markers

    0.61 Metres square >


Visual communications1
Visual Communications

Helicopter Operating Areas:

  • The ‘H’ is 4 metres high by 2 metres across

  • It may also have a box around the ‘H’.

  • Well clear of fixed wing aircraft

OR


Radar
Radar

Stands For:

RAdio

Detection

And

Ranging


Radar1
Radar

Consists of a Transmitter and a Receiver

A short pulse energy is transmitted from an aerial and the receiver “listens” for an echo.


Radar2
Radar

The receiver detects which reflections are from aircraft, and it can determine their position, direction of travel and speed.

This information is then displayed through a cathode ray tube onto a screen. In this way radar has become the “eyes” of air traffic control


Radar aids
Radar Aids

The two main radar aids likely to be seen at Royal Air Force airfields are:

Surveillance Radar

Precision Approach Radar (PAR)


Surveillance radar
Surveillance Radar

Is used both to monitor air traffic passing through an area and as an airfield approach aid.


Surveillance radar1
Surveillance Radar

Enables the controller to locate the aircraft and direct it to a position and height near the airfield


Precision approach radar
Precision Approach Radar

The controller has two screens, one for the aircraft’s elevation (height) and one for azimuth (left and right), relating to the approach path


Precision approach radar1
Precision Approach Radar

The controller passes instructions by RT to the pilot to guide the aircraft down the correct glide slope towards the touch-down point

The procedure is called a Ground Controlled Approach (GCA).

PAR 2000 Radar


Radio aids
Radio Aids

The two main Radio Aids likely to be seen at Royal Air Force airfields are:

Digital Resolution Direction Finding (DRDF)

Instrument Landing System (ILS)


DRDF

It is a common airfield approach aid

It receives an transmission from an aircraft and displays it on a CRT as a green line called a “trace”.

Enables the approach controller to tell the pilot what course to fly to reach the airfield


Instrument landing system
Instrument Landing System

ILS is a runway approach aid:

Fixed transmitters on the ground send out a special pattern of radio signals

These define a radio beam that is like a pathway in the sky

The pathway then leads to the touch-down point on the runway


Instrument landing system1
Instrument Landing System

ILS transmits 2 frequencies

  • 90Hz (aircraft is too high)


Instrument landing system2
Instrument Landing System

ILS transmits 2 frequencies

  • 150Hz (aircraft is too low)


Instrument landing system3
Instrument Landing System

ILS transmits 2 frequencies

  • No noise = Good glide path
