1. Installation and Transition Operational Impact

1.1 Site surveys

1.1.1 General

1.1.1.1 The main task of the site survey is to define the right type, number and positionfor the equipment’s placement on the airfield.

1.1.1.2 The site survey should be performed by the Bidder for each type of theequipment separately.

1.1.1.3 There are a lot of factors, which could affect to the right placement of thedifferent types of the equipment.

1.1.1.4 At least the following factors should be taken into account:

1.1.1.4.1 Distance from the runway, taxiways and apron;

1.1.1.4.2 The complexity of the landmark for the installation and cabling works;

1.1.1.4.3 The presence of the other obstacles in the proximity to the equipment;

1.1.1.4.4 The interference between the different types of the equipment;

1.1.1.4.5 The necessity to create the infrastructure for the proper maintenance of theequipment in the future.

1.1.2 The distance from the runway, taxiways and apron

1.1.2.1 The placement of the equipment should be done strictly in according with theICAO, WMO and NATO rules.

1.1.3 The complexity of the landmark

1.1.3.1 The necessity of the civil works including ground levelling, drainage, cutting oftrees and bushes, etc. should be taken into account for the each type of theequipment according to the requirements.

1.1.4 The presence of the other obstacles

1.1.4.1 There are a number of rules defined for the objects on the airfield. These rulesare described in the corresponding documents.

1.1.4.2 There are the number of the parameters such as height, for example, whichshould not exceed the certain limits depending on distance from runway andtaxiways.

1.1.5 The interference with other equipment

1.1.5.1 It should be taken into account the possible interference with other type of theequipment installed on the airfield.

1.1.5.2 There is the number of rules for each type of the equipment. These rules areprescribed in the corresponding documents/attachments.




1.1.6 The establishing of the infrastructure

1.1.6.1 The each type of the equipment should be connected to the power andcommunication network (there are a few exceptions exist)

1.1.6.2 The power network infrastructure should be created to provide the adequateand suitable power mains for each object on the airfield.

1.1.6.3 The reasonable number of the power distribution units and diesel-generatorsshould be installed.

1.1.6.4 It is possible to share the one power distribution unit for several objects on theairfield.

1.1.6.5 The communication network should be built based on 2 major criteria:

1.1.6.5.1 It should be redundant for every object;

1.1.6.5.2 The topology of the network should be optimized. For example, it is possible touse one cable trench for the communication network provision till severalobjects. The pipes will be shared in that case.

1.1.6.6 The area around every object should be prepared for the further maintenance.It should be possible to make every object accessible by car all year round.

1.2 Survey’s priority

1.2.1 General

1.2.1.1 It is very important to define the priority of the surveys.

1.2.1.2 The every next survey should take into account the results from the previoussurveys.

1.2.1.3 The sequence of the surveys is described below:

1.2.1.3.1 The navigation Aids – ILS, D-VORTAC;

1.2.1.3.2 The meteorological equipment – Wind/Visibility/Clouds Sensors, etc.;

1.2.1.3.3 Communication (Transmitters/Receivers) center.

1.2.1.4 It should be necessary to create a map/detailed scheme of the airfield, whereall the survey’s results should be reflected.

1.2.1.5 This map should be up to date.




1.3 Requirements to the Navigational Equipment

1.3.1 ILS

1.3.1.1 The instrument landing system (ILS) The ILS uses a line-of-sight signal from thelocalizer antenna and marker beacons and a reflected signal from the groundplane in front of the glide slope antenna.

1.3.1.2 ILS antenna systems are susceptible to signal interference sources such aspower lines, fences, metal buildings, etc.

1.3.1.3 Since ILS uses the ground in front of the glide slope antenna to develop thesignal, this area should be graded to remove surface irregularities.

1.3.1.3.1 The Localizer Antenna (LLZ) signal is used to establish and maintain theaircraft's horizontal position until visual contact confirms the runway alignmentand location. The LLZ antenna is sited on the extended runway centerline 1,000to 2,000 feet (300 to 600 m) beyond the stop end of the runway. The LLZequipment shelter is placed at least 250 feet (75 m) to either side of theantenna array and within 30 degrees of the extended longitudinal axis of theantenna array.

1.3.1.3.2 The Glide Slope Antenna (GP) signal is used to establish and maintain theaircraft's descent rate until visual contact confirms the runway alignment andlocation. A GP differentiates precision from non-precision approaches. The GPantenna may be located on either side of the runway. The most reliableoperation is obtained when the GP is located on the side of the runway offeringthe least possibility of signal reflections from buildings, power lines, vehicles,aircraft, etc.
