History - Bikaner's history dates back to 1488 AD when a Rajput prince Rao Bika ji a

descendent of the founder of Jodhpur (1459 AD)., Rao Jodha Ji established his kingdom there. Bika Ji chose a barren land called "Jungladesh" and shaped it into an impressive city, called Bikaner after the founder's name. Archeological surveys and excavations have

established beyond doubt that civilization flourished here even before the Harappa period .



Excavated statues, coins and carvings of stones and clay stands as testimony to this fact. Ever since the foundation of Bikaner till its accession into Indian Union in 1947 A.D. and

there after it's integration in Rajasthan state in 30-3-1949 A.D., Bikaner has played a

notable role in the history of the country. Tourist Places in & around Bikaner – (a) Junagarh - Built in 1593 A.D. the fort is a formidable structure encircled by a moat

and has some beautiful palaces within. These palaces, made in red sandstone (Dulmera) and marble, make a picturesque ensemble of countryards, balconies, kiosks and windows dotted all over the structure.The imposing fort has 986 long

wall with 37 bastions and two entrances. (b) Deshnoke Karni Mata Temple - 30 Km south of Bikaner on the road of Jodhpur,

stands a little town-DESHNOKE, is known for the shrine of Karni Mata, who is

worshiped as an incarnation of Goddess Durga. The temple is unique as the rats called Kabas, are venerated here and the shrine is a sanctuary for them. It is believed that these Kabas carry souls of future Charans/bards (children of the

goddess) who inhabit the town of Deshnok. These Kabas are held sacred and they move freely in the temple precincts. It is considered highly auspicious to sight a

white Kaba. (c) Kolayat Temple - 51 Km from Bikaner on highway leading to Jaiselmer - an old

pilgrimage centre where Kapil Muni of the vedic fame is believed to have shed his body under a peepul tree. Kolayat has a series of charming marble temple, sandstone pavilions and 32 ghats (bathing places) built around a huge artificial lake

which never goes dry. Here one can see sadhus and pilgrms taking a holy dip, surrounded by the vast emptiness of a timeless atmosphere and the golden desert. On Karthik Purnima day a grand fair is held in which devotees from all over the

country come to take a holy bath in the lake. (d) Gajner Palace & Sanctuary - Situated at 30 Kms. From Bikaner on highway

leading to Jaisalmer Gajner Palace has often been described as ' an incomparable

jewel in the Thar desert'. Palace stands on the embankment of a lake . The architecture of Gajner palace is truly outstanding. Built in red sandstone with intricately carved pillars,jharokhas and screens , the craftsmanship here is amazing.

A part of palace has been transformed into hotel. The wildlife sanctuary provides shelter to chinkaras , blackbucks, blue bull (neel gai),Wild Boar and flocks of imperial sand grouse and many other birds and waterfowls which flock here in large

numbers.



2.2 AAI Ofiices:

The AAI has three sites at Bikaner:

i) Office-cum-residential Complex.

ii) LUNKA-I DVOR/DME Site.

iii) LUNKA-II DVOR/DME Site.

2.2.1 The Office-cum-residential Complex is about 6 Kms. away from the Railway Station at Khaturia Colony.

2.2.2 The LUNKA-I site is about 90 Kms. away from the Office-cum-residential

Complex & located at Village Bhadera on NH 15 leading to Ganganagar

(Total area of the Operational site Complex is 16 Bigha Approx.)

2.2.3 The LUNKA-II site is also about 90

Kms. Away from Bikaner office at village Thukariasar on road leading to Hisar & Delhi. It is 15 kms. off from Sridungargarh

on NH 11 Bikaner Jaipur highway. (Total area of the Operational site Complex is 14

Bigha Approx.)

2.2.4 There is also an operational air-base at Nal, Bikaner solely under the control of

IAF and also presently used for civil aviation operation.

2.3 Station’s role in route navigation

The station provides a range of ground-based devices to assist en-route

navigation. DVOR is the main aid to navigation, providing a radio signal that enables a pilot to take his bearing from a

particular station; and co-installed with it is a DME, by interrogating which he can compute his distance from that point.

This combination of DVOR/DME is the ICAO standard short-range navigation and position fixing system. ATC instructions

are required by the pilots to fly a particular course or patterns and these are normally linked to individual VOR

'radials' or positions. Outside controlled airspace the pilot can navigate independently with reference to VOR/DME,

which can also provide a reliable means of defining a predetermined approach to its destination.

2.4 Organisational Structure:

2.4.1 At present the station is posted

with Three executives (including Officer-in-charge) and one MT Supervisor. The three executives comprises of one each

from Senior Manager, Manager and Assistant Manager level.

2.5 Accountability:

2.5.1 The officer-in-charge, Aeronautical Communication Station, Airports Authority of India is responsible for ensuring the

safe, efficient and secure provision of the station facilities and also accountable for all ongoing operational/administrative

deliberations at the station.

2.5.2 The activities required to execute these responsibilities include:

Establishment and Management of an independent Aeronautical Station.

Implementation of ICAO Norms.

Promulgating the CA Requirements.

Modification of the Facility.

Various joint and cooperative activities with different agencies.

2.6 Human Resource:

2.6.1 A Navigation facility maintenance

personnel should be specialists in the field. An important element in a preventive maintenance programme is trained

experienced personnel. The authority responsible for the maintenance should have a thorough knowledge of the

equipment, should have experience with extra-ordinary skill and should be able to make careful inspections for necessary

repairs and modifications, if required. It is desirable for the other staff to have

professional training. For maintenance purpose, well-qualified executives can be trained on-the-job if suitable supervision

and instructions are provided. Considerable exposure to the equipment and its operation is desirable. These

individuals should be present or on-call during 24 hours of the station to correct any deficiencies that may develop.

2.6.2 This station is supposed to have a watch round the clock, but due to

shortage of staff, a daily visit of the maintenance team is paid to asses the health of the equipments and to execute

the desired maintenance.

CHAPTER 4

MAINTENANCE MANAGEMENT

Two Basic Rules

A potential hazard exists whenever work is performed on or around energized

radio/electrical equipment.

The following basic rules should be followed by all personnel:

a) Work should never be performed on energized electrical conductors or

equipment, except for measuring voltage or current.

b) Always assume that power is on until the true condition is determined.

4.1 General:

This chapter provides recommended guidelines for maintenance of navigational aid. Since the function of such facilities, in context to this station, is to assist in the safe and efficient movement of aircraft while en-route to destination, it is essential that a high degree of

operating reliability be maintained. To achieve, it is necessary to establish and maintain an effective system of maintenance programme. This section provides suggestions for establishing this type of programme but, due to the varying complexities prevailing at the

station and facilities provided, such a programme must be tailored to suit each particular need of the time subject to the condition that the basic sprit should not be compromised.

4.2 Maintenance Philosophy:

The purpose of a maintenance management system is to ensure the maximum availability

of any given system at a minimum cost in man-hours of funds. "Availability" and "costs" are relative terms; they must be interpreted for each facility. Maintenance of the navigational aid is a mission essential for all air operations. Maintenance operations must

be scheduled and coordinated with all concerned. The maintenance operations include maintenance planning, preventive maintenance inspection, visual inspection, repair, ground-calibration and scheduled maintenance procedures.

The maintenance procedures in this manual are considered minimum guidelines. The

following points are essential to any controlled maintenance program.

a) Documenting the service checks of the maintenance program.

b) Recording the performance of scheduled or unscheduled maintenance action.

4.3 Maintenance Schedules:

Documenting the maintenance schedule by spelling out each item of routine maintenance is beneficial in several ways:

a) It allows planned allocation of man-hours to the maintenance function.

b) It helps to establish spare part stock at the appropriate level (SMUs).

c) It identifies the necessary maintenance routines to new staff, decreasing training time needed for system familiarization.

d) It identifies to management the scope of the maintenance task in terms of man-hours and materials requirements.

4.3.1 Preventive Maintenance Inspection Practices (Daily):

Reliable functioning of navigational aids is necessary for air-movement. Though ground support navigational aid equipment is designed to be dependable and may continue to operate for long periods of time even if the maintenance is neglected, yet it is essential



that a preventive maintenance programme be established to ensure reliable service and proper equipment operation.

An important factor of preventive maintenance programme is an effective Preventive Maintenance Inspection (Daily) schedule. This daily schedule is the foundation for the successful maintenance of the equipment. If the daily schedule is performed properly, it

will ensure top system performance and will minimise unscheduled interruptions and breakdowns. A review of the inspection records, checks, tests and repairs provides a constant awareness of the equipment condition and gives maintenance personnel advanced

warning of impending trouble.

This includes the following checks on daily basis:

i) Building Condition—cracks, leakage etc. ii) Antennae System and Associated Structure—corrosion, welding, foundation etc.

iii) Room Temperature/Air-conditioning. iv) Cleaning of equipment/Eqpt. Room/condition of PVC flooring. v) Wiring Condition—abrasions, breaks, and loose connections etc.

vi) Connectors/Electrical Jumpers—looseness, moisture, rusting etc. vii) Mechanical Systems—lubrication etc. viii) Rodent/Lizard/Insect Prevention.

ix) Visit to other establishments (Generator Room etc. for similar observations). x) Lightening Arrester. xi) Earthing System.

xii) Obstruction Light.

4.3.2 Periodical Maintenance:

Scheduled inspections and tests are those accomplished on specific types of equipment on a periodic basis. The schedule may be based either on calendar or on hourly use

increments. These schedules are based on recommendations from the regulatory authority or from the manufacturers and users of the equipment. These schedules are considered to be the typical requirements to keep the equipment in good condition. In our case it is a

multi-phased programme, viz, daily, weekly, monthly, quarterly, half yearly & annualy. This is subjected to:

a) Monitoring of operational parameters b) Perfect functioning of monitoring device (within standard tolerance) and

warning/alarm etc. c) Equipment’s behavior under the alarm condition (change over, shut down, restart

generations etc.)

d) Alignment/Calibration/Tuning of equipment and accessories according to procedure.

4.4 Performance Checks:

4.4.1 The efficiency of any facility depends upon checks and counter checks. The

Performance Check is also a counter check type of maintenance in which the parameter measured has to be tallied/compared with station’s previous records in a routine or required manner. It includes the following check:

i) Various Voltage/Current levels (available at TPs & jacks) ii) Wave Shapes

iii) Monitoring Levels iv) Station Assigned Frequency v) Power Levels of various signal/Output Power

vi) Level of internal signal generators. vii) Modulation Percentage viii) VSWRs

ix) Lightening Arrester x) Earthing System



4.4.2 All these checks should also be carried out for associated units/test equipments to assure the safe operation of facility.

END



4.6 Troubleshooting:

Before attending the equipment/unit, it may be ensured that power supply to the equipment/unit is of specified rating. In case of AC supply, the voltage and frequency is of

the rated value whereas in case of DC supply voltage and ripple filtering is very important.

The common approach of troubleshooting is:

i. Smell out any burnt/overheating component.

ii. Check-up for male/female connector along with its pins and ensure its proper

insertion.

iii. Similar exercise may be carried out for all edge connectors and ribbon

connectors.

iv. Check the Earthing of the equipment. Improper/floating/dry earth sometimes

plays havoc despite of perfect status of the equipment.

To avoid any further damage, It is advisable to isolate the onwards stages or to reduce the power handling level if and only if the situation permits.

These were the only general methodology for fault finding. It is recommended that a

procedural approach referring to manufacturer’s manual should be adopted for the purpose. A record to this effect should also be made in the Fault Log Book.

4.7 Tools & Test Equipments:

An important element in a maintenance programme is the tools and test equipment

required to perform the task. This includes the proper tools, test equipment, adequate working space, adequate storage space, spare modules and applicable technical manuals. Carrying out the maintenance with the perfect and calibrated test equipments curbs the

equipment failure, false signals, and deterioration of the system. 4.8 Maintenance Records:

Maintenance records are an important part of an effective maintenance management

system. They provide a service history of each piece of equipment’s sub-units, ensure regular maintenance without duplication of effort, and give a data base for statistical analysis of system performances. Without records, knowledge gained from regular

inspections will not be retained, and preventive maintenance will be difficult. An effective records system should allow for the recording and retrieval of information with a minimum of effort. The records system should compile data that will document the

effectiveness of the maintenance program. By checking the records, a proficient executive will be able to determine whether a particular maintenance task is being done too frequently or not often enough.

Since corrective and preventive maintenance procedures for the equipment are adequately

addressed in CHQ CNS Manual, this manual contains the compact, recompiled and comprehensive user friendly parameter recording formats for the maintenance schedules as well as the status reports to be sent to respective RHQ as per the instructions. These are

given in Annexure pages as detailed below:

4.10 Preservation of Records:

There is no set period of time that maintenance records should be kept, but, in keeping within the goals mentioned above, the respective period of preservation of record for each type of maintenance with respect to facilities at this station is well defined in CNS Manual,

Vol. I and is appended below:

i) Daily One year ii) Weekly One year iii) Monthly One year

iv) Quarterly Five year v) Six Monthly/Annual Five year vi) Ground Calibration Repots One year

vii) Flight Calibration Reports Last 5 Reports along with commissioning report viii) Performance Indicator Report One year viii) Fault Log Book Till discarding of the equipment

4.11 Reference Librarary:

A reference library should be established to maintain a master copy of all equipment’s technical manuals, advisory CNS circulars, as-built drawings, master copy of this manual and other useful technical data such as local electrical codes/wiring diagrams, test

equipment manuals etc. An officer of primary responsibility has been designated to maintain the records.

IMPORTANT CAUTION After every maintenance, it should be ensured that all the parameters of both

(main and Standby) equipments must be normal and well within the tolerance limits as specified by ICAO/CA Requirements otherwise carry out a fresh

procedural exercise and record.

A ground check/flight check of DVOR, as the case may be, is also advisable to

ensure air safety.



CHAPTER 5

CRISIS PLANNIG AND COORDINATION

5.1 General

The air-space with few operations may suffer with a little inconvenience to pilot as well as

to ground controller in managing the show without Navigational Aid but the management of a crowded air-space without the provision of such aid is quite risky for the both. That too if failure occurs at a critical time, it may lead lives and property be jeopardized. The concept

of Hot Stand-by has solved the problem up to certain extent, still unpredictable failure of the facility some times inevitable due to natural reasons. Hence navigational aid restoration should receive high priority in the interest of air-safety.

5.2 Availability of serviceable card/module/unit:

This section contains guidelines on how to manage serviceable modules to be replaced, co-

ordination with appropriate levels for quick restoration of station facility.

5.2.1 Special Maintenance Units (SMUs):

Under the modernisation plan, the AAI has adopted a cetralised maintenance workshop concept (CMC/SMUs) at different airports for different facilities. The Special Maintenance Unit (SMU), New Delhi is identified as the cetralised maintenance unit for the facilities

commissioned at this station.

In the event of unexpected failure of facility and in order to minimising the facility’s out of operation time, following guidelines have to be adopted:

a) Isolate, pack and dispatch the faulty module/card along with telephonic coordination to SMU, New Delhi. Intimate via e-mail to CMC with a fault briefing report as per Performa CMC-01. (Ref. Caution ‘f’ in packing ESD sensitive device, Annexure page A-2)

b) SMU, in turn, acknowledges station by raising a Site Anomaly Report (SAR) as per

Performa CMC-02.

c) After servicing and hot check or replacement, the card is again dispatched back to

station as per Performa CMC-03.

d) Upon receipt of the module/card at the station,

i) if the performance is satisfactory—Normalize the station and intimate all concerned as well as SMU to close SAR as per Performa CMC-04.

ii) if the performance is faulty—Again dispatch the faulty module/card along with telephonic coordination to SMU, New Delhi according to defined procedure

bearing the same SAR number.

5.3 Effect of the Failure:

The effect of the failure of a particular spare part depends on how important the part is to

the equipment it is installed in, and/or how vital the equipment is to operation. For example, the failure of an indicator lamp in a unit would not lead to any system downtime whereas any breakdown in a circuit board/module would cause the failure of the entire

facility. The recurrence failure of a particular card/module/unit should be given due consideration to sort out the problem permanently.

5.4 Facility Malfunction:

In the event of failure of a facility irrespective short-termed or prolonged, It is mandatory for the service provider to coordinate with appropriate authority who can inform all such

time-critical aeronautical information to every concerned which could affect a pilot's decision to make a flight. Even after restoration of the facility similar liaison is mandatory.



5.4.1 NOTAM (Notice to Airmen):

It is a notice distributed by means of telecommunication containing information concerning

the establishment, condition or change in the status any aeronautical facility, service, procedure or hazard, the timely knowledge of which is essential to all concerned parties involved in flight operations. The person in charge of the watch shall report any known or

reported malfunctions of a NAVAID to technical operations or appropriate personnel and coordinate issuance of a NOTAM.

In the case of this station and under such circumstances, all time based coordination has to be carried out with SSO (Tech.), Palam, New Delhi. (Phone: 011-25653492) with the following details:

Specify an acceptable recovery time for the shutdown facility.

The procedure to be repeated if the acceptable recovery time of a service is exceeded or

Specify time about the restoration of the shutdown facility, if already restored.



CHAPTER 6

MONITORING AND SAFETY

6.1 General:

To establish the technical efficiency, maintain safety and adequate levels of reliable service of these facilities, a continuous monitoring is being carried out. The systems do have automatic monitoring that shut down the equipment if it puts out an unsafe signal.

Unmonitored, as used in this order, means that the personnel responsible for monitoring the facility have lost aural and visual monitoring capabilities and cannot observe the status of the facility or not physically present at the site. It does not refer to the automatic

monitoring feature. Monitoring is accomplished in following ways:

6.1.1 Executive Monitoring:

It is an electronic means in which the system checks its critical parameters itself and in the event of an out of tolerance condition, either changes to an auxiliary back-up equipment or shuts the system down if there is no redundancy or if the redundant circuit is also failed.

This monitoring is continuous.

6.1.2 Status Monitoring:

This is an automatic notification, either to the maintenance centre or to an operational position, that the system has taken an executive action and the navigation system is changed over or off-the-air. Many NAVAIDs are not continuously status–monitored.

6.1.3 Air Calibration:

NAVAIDs are flight inspected by specially equipped aircraft on a regular basis to ensure that

standards are met and certifies the facility is air-worthy. In case of DVOR/DME, It may be noted that it has to be carried out at an interval of every 730 + 30 days.

6.1.4 Pilot Monitoring:

When a pilot tune and identify NAVAIDs prior to use and afterwards gets the satisfied performance of the facility as per the standards, this is called Pilot Monitoring.

6.2 Safety:

It is the responsibility of every AAI employee involved with the CNS activities to understand and help achieve the following safety goals:

• Provide a safe and healthful working environment for all other colleague employees. • Incorporate safety aspects into maintenance operations planning. • Reduce operating costs and increase mission capability by protecting human and material assets. • Eliminate hazardous conditions.

Similarly, the aviation safety program is composed of three elements. They are standardization, compliance, and hazards identification.

• Standardization is an ongoing responsibility of all personnel associated with aviation activities. • Compliance with safety policies, procedures, and practices as spelled out in this manual and

associated document is the responsibility of every maintenance team. • The Hazard Identification System is both an informal and a formal reporting system. Aviation

personnel are expected and encouraged to inform their subordinates of a hazard.

The end result of these combined efforts of all above is a navigation system that is

safe, reliable and air-worthy and meets the established standards.

TIPS FOR MAINTENANCE

ELECTROSTATIC DISCHARGE & GENERAL WARNINGS FOR ALL EQUIPMENTS

CAUTION: THIS EQUIPMENT CONTAINS ELECTROSTATIC DISCHARGE (ESD) SENSITIVE

DEVICES. TO PREVENT ESD SENSITIVE EQUIPMENT FROM POSSIBLE DAMAGE, OBSERVE THE

FOLLOWING PRECAUTIONS WHEN HANDLING ANY ESD SENSITIVE CARD/UNIT/MODULE:

a. Maintenance or service personnel must be grounded though a conductive wrist strap, or a similar

grounding device, using a 1 MΩ series resistor for equipment protection against static discharge, and

personal protection against electrical shock.

b. All tools must be grounded (including soldering tools) that may come into contact with the equipment.

Hand contact will provide sufficient grounding for tools that are not otherwise grounded, provided the

operator is grounded through an acceptable grounding device such as a wrist strap.

c. Maintenance or service of the faulty card/unit/module must be done at a grounded, ESD workstation

i.e. SMU, New Delhi.

d. Before maintenance or service of the equipment, disconnect all power sources, signal sources, and

loads connected to the unit.

e. If maintenance or service must be performed with power applied, take precautions against accidental

disconnection of equipment components. Specifically, do not remove integrated circuits or printed

circuit boards from equipment while the equipment has power applied.

f. All faulty ESD sensitive faulty card/unit/module are to be transported to SMU in electrically conductive

foam bags. The faulty card/unit/module should preferably be stored using the original

container/package when not being used or tested. If the original storage material is not available, use

similar or equivalent protective storage material.

g. Whenever a faulty ESD sensitive card/unit/module is removed, the same must be placed on a

conductive surface, or in an electrically conductive container.

h. When in storage or not being repaired, all printed circuits boards must be kept in electrically

conductive bags, or other electrically conductive containers.

i. Do not unnecessarily pick up, hold, or directly carry ESD sensitive devices. Failure to comply with

these precautions may cause permanent damage to ESD sensitive devices. This damage can cause

devices to fail immediately, or at a later time without apparent cause.
