Introduction:

BEFORE going Airside: Familiarise yourself with AFL Airfield Safety Runway and Taxiway designations Driving Regulations REDUCE THE CHANCE OF ACCIDENTS ! KEEP THINGS ....... SIMPLE and SAFE ! Introduction

Introduction:

What is an Airfield / Aerodrome? For the Recovery ( Landing ), Support & Take-off of Air Vehicles ( Aircraft ) What are the key aspects to establish Airfield Facilities with respect to the Aircraft’s operations? From the Air to the Ground ( Runway ) for Landing From the Runway to the Terminal/Apron for Replenishment From the Terminal/Apron to the Runway for Take-off From the Runway to the Sky – Take-off ! Introduction

What are the key aspects to establish Airfield Facilities with respect to the Aircraft’s operations? From the Air to the Ground ( Runway ) for Landing RUNWAY Lighting ( Landing ) From the Runway to the Terminal/Apron for Replenishment TAXIWAY Lighting From the Terminal/Apron to the Runway for Take-off TAXIWAY Lighting From the Runway to the Sky – Take-off! RUNWAY Lighting ( Take-off ) Introduction

Definition of Visual Landing Aids (AFL):

Definition of Visual Landing Aids (AFL) Aid to Air Navigation Visual & Harmonises with ILS Complies with Runway Visual Range (RVR)

The principle of a basic AFL system:

The Series AFL Circuit CCR [Constant Current Regulator] Incoming Electrical Supply Command Back Indication CMS [Control & Monitoring System] The principle of a basic AFL system

The principle of a basic AFL system:

The principle of a basic AFL system AGL constant current series circuit configuration - IEC 61820 Primary Series Circuit Input Disconnecting Device Cut-out CCR Control cables AGL Series Transformer Light

The principle of a basic AFL system:

CCR 6.6 A Ip=6.6 A Ip=6.6 A Ip=6.6 A Ip=6.6 A Is =6.6A Is =6.6A Is =6.6A Is =6.6A Constant current is maintained throughout the series circuit. (Ip=Is) The principle of a basic AFL system

AFL series field circuit:

AFL series field circuit 6.6 Amps in primary circuit High voltage up to 5 kV Cables: 100 ‘s kilometres on an airfield installation Braided /Screened / Armoured (although on some airfields un-braided may be found) Connections: Plug/Socket connectors Crimps

AFL series field circuit:

AFL series field circuit Isolating Transformers: Ratio @ 1:1 Designed to withstand 5kV operating Power Source Normally 415V 2 Phase via Distribution Board & Switch Breaker Constant Current Regulator (CCR) High Volts / 6.6Amps

AFL circuit isolation:

AFL circuit isolation Basic Principle of Operation Risk Assessment Power OFF Power ISOLATED Earth Down Primary Field Circuit Authorisation / Permit to Work

Golden Rules:

Golden Rules Plan Work & Obtain Permission Isolate Prove Dead and Earth Down Permit to Work issued Confirm Dead
