Air traffic control (ATC) It is a service provided by ground-based controllers who direct aircraft on the ground and in

the air. The primary purpose of ATC systems worldwide is to separate aircraft to prevent collisions, to

organize and expedite the flow of traffic, and to provide information and other support for pilots when able.

In addition to its primary function, the ATC can provide additional services such as providing information to pilots, weather and navigation information and NOTAMs (Notices to Airmen).The DR100 multimode VHF receiver

It is a state-of-the-art communication unit specifically designed to operate as radio core part of Air Traffic Control ground stations.

It is able to support a huge number of operating modes, ranging from the traditional AM-DSB mode for analogue speech communications, to the latest VDL 3 and 4 modes* for voice and data or data-only links.

Due to its DSP-based architecture, software-radio approach, and modular design, it allows for easy update and re-configuration in terms of type of modulation, channel spacing and interface to external controllers.

The equipment has outstanding performances in terms of noise radiation and unwanted emissions together with the high grade of immunity to external interference.

The equipment has been designed to fulfill operating requirements in any possible system layout. This results in an extreme degree of flexibility and operability. It can also be used as direct replacement of analogue VHF equipment in traditional ATC systems

DVTR The Digital Voice Tape Recorder is used for audio recording. It can record 24 channels simultaneously. In this about 20 channels are fixed while remaining 4 channels can be set as

requirement. Recording is done on magnetic tape and saved about 2 months.

Navigation•Navigation is the ART of determining the position of an aircraft over earth’s surface and guiding it’s process from one place to another.•To accomplish this ART some sort of aids are required by the pilots, called the navigational aids.•Radio Navigation is based on the use of Radio Transmitter, Radio Receiver and propagation of electromagnetic waves to find navigational parameter such as direction, distance, position of the aircraft etc.• According to service range the radio navigational aids are broadly classified into three categories -1. Long Range.2. Medium Range.3. Short range.

1. Long Range navigational aids•Operate in very low frequency and low frequency, i.e. 10KHz, 50-100KHz and 100-200KHz respectively.•Provide very long ranges of the order of 7000Kms and 700Kms.•They are based on the hyperbolic system of navigation. •LORAN and OMEGA falls in this category.

05/01/2023 PIET/EC/12/110 15

2. Medium range navigational aids• It operates in the LF or MF band of frequency .• It gives the range of 150-250 nautical miles.• NDB (Non Directional Beacons) falls in this

category.3. Short-range navigational aids• These aids operate in and above VHF bands.• The coverage is dependent upon line of sight

propagation.• VHF, ILS, DME, VOR and RADAR are some widely

used short-range aids.

NAV AIDS

I.L.S. (Instrument Landing System)

Localizer : Helps aircraft to identify the central line of runway. Range:- 10-25 NM Frequency:- 108-111.9 MHz Glide Path : Gives the glide angle i.e. angle of declination achieve for safe landing. Range:- 10 NM(-8 to +8 degrees) Safe glide angle:- 2-4 degrees

DISTANCE MEASURING EQUIPMENT(DME) :

DME is used in navigational aid which provide a pilot with visual info regarding his position(distance) related to ground base DME station. The frequency range used for DME is between 960 MHz to 1215 MHz . This frequency is used because it has better frequency stability comparative to next higher frequencies in microwave band. It has less reflection and attenuation.

05/01/2023 PIET/EC/12/110 19

VHF OMNI-DIRECTIONAL RANGE (VOR)

* It is a type of radio navigation system for aircraft. VORs broadcast a VHF radio signal encoding both the identity of the station and the angle to it, telling the pilot in what direction he lies from the VOR station, referred to as the radial.

* It operates in the VHF band of 112-118 MHz, used as a medium to short range Radio Navigational aid. It works on the principle of phase comparison of two 30 Hz signals

* There are two types of VOR, namely, conventional VOR (C-VOR) and Doppler VOR (D-VOR).

RADAR

◙ Radars are employed throughout the world for the purpose of safely controlling air traffic en-route and in the vicinity of airports.

◙ Aircraft as well as vehicular traffic at large airports are monitored by means of high-resolution radar.

◙ Radar has also been used to guide aircraft to a safe landing in bad weather.

05/01/2023 PIET/EC/12/110 27

X-RAY BAGGAGE INSPECTION SYSTEM

This system has a single X-ray source sending out X-rays, typically in the range of 140 to 160 kilovolt peak (KVP). KVP refers to the amount of penetration an X-ray makes. The higher the KVP, the further the X-ray penetrates.

After the X-rays pass through the item, they are picked up by a detector. This detector then passes the X-rays on to a filter, which blocks out the lower-energy X-rays.

The remaining high-energy X-rays hit a second detector. A computer circuit compares the pick-ups of the two detectors to better represent low-energy objects, such as most organic materials.
