The Air Transport industry plays a major role in
world economic activity.
The process of getting an Aircraft Safely and
Efficiently to its destination depends on three
functions of Air Navigation:
Communication,
Visual Aids(Airfield Ground Lighting) and
Surveillance.
Air Travel is the Safest and Fastest Means of Transportation

AERODROME VS AIRPORT
AERONAUTICAL VS AIRFIELD
TERMINOLOGY
AERODROME – A defined area on land (including any buildings,
installations and equipment) intended to be used either wholly or in part
for the arrival, departure and surface movement of aircraft.
AERONAUTICAL GROUND LIGHTING – Any light specially provided
as an aid to air navigation, other than a light displayed on an aircraft.
System is the generic term used to describe the various lighting system
that are provided on an aerodrome for the guidance of pilots operating
aircraft both at night and in low visibility condition.

National Organizations
In addition to the requirements of international organizations,
there are also requirements by national aviation organizations
The objectives of these organizations are to prepare national
laws, defend national interests concerning the market, etc.
• USA: Federal Aviation Administration (FAA)
• E.G. India : Directorate General of Civil
Aviation (DGCA)

FAA http://www.faa.gov/
The Federal Aviation Administration (FAA) is the element of the U.S.
government with primary responsibility for the safety of civil aviation. The
FAA was originally designated the Federal Aviation Agency when
established by the Federal Aviation Act of 1958.The present name was
adopted in 1967 when the FAA became a component of the Department of
Transportation. The FAA’s major functions include:
• regulating civil aviation to promote safety and fulfill the requirements of national
defense
• encouraging and developing civil aeronautics, including new aviation
technology
• developing and operating a common system of air traffic control and navigation
for both civil and military aircraft
• research and development with respect to the National Airspace System and
civil aeronautics
• developing and implementing programs to control aircraft noise and other
environmental effects of civil aviation
• regulating U.S. commercial space transportation

Why Airfield Ground Lighting (AGL)?
The optical landing aids at an airport are an extension of an aircraft’s
navigation facilities on the ground.
They are deployed for the most varied of visibility conditions such as
day (brighter light more likely) and night (dimmer), in fog or heavy
rainfall, but also in the haze experienced when the sun is ahead.
In order to adapt these varying conditions, the intensity of the lights
must be adjustable with regulators. If one further considers that the
touch down speed of an aircraft approaches something like 250 km/h,
it is easy to understand that the demand for reliability of the lighting
installation is also extremely high. The sequential failure of several
lights under bad weather conditions is thus unacceptable (ICAO-
recommendation).
This is one of the reasons for a two or three time redundant system
design for almost all lighting systems.
The visual aids are contained to Runway edge lights ,Runway Center
Line Lights, PAPI System, Approach lights, Taxiway Center line lights ,
Threshold lights and Taxiway Edge lights, Stop Bars and Signs etc.

Advantages for having ASD Circuits
• This provides intelligence in Airfield Ground Lighting system and its control
system
• Lots of cables and CCRs quantity can be saved
• Proper recording of exact lamp failure ,which helps in reducing maintenance cost
and enhance operation capabilities ,specially informs about adjacent lamp
failure.
• Allows to go for ASMGCS in future.
• Precise control of each segment of runways , Taxiways
• Optimizes runway closing for Maintenance , which results increments in traffics
and revenue
• Ensures safe and reliable guidance to aircraft .
• Reduces installation times
• No additional hardawres would be required for Runway Guard Lights.
• Informs failed lamp detections and locations
