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

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
