18 Procedures for Protection of Critical Area and Sensitive Area of ILS during Low Visibility Operations at Jaipur International Airport
18.1 The occurrence of interference to ILS signals is dependent on the total environment around the ILS antennas, and the antenna characteristics. Any large reflecting objects, including vehicles or fixed objects such as structures within the radiated signal coverage, will potentially cause multipath interference to the ILS course and path structure. The location and size of the reflecting fixed objects and structures in conjunction with the directional qualities of the antennas will determine the static course or path structure quality whether Category I, II or III. Movable objects can degrade this structure to the extent that it becomes unacceptable. The areas within which this degradable interference is possible need to be defined and recognized. For the purposes of developing protective zoning criteria, these areas can be divided into two types, i.e. critical areas and sensitive areas:
a. The ILS critical area is an area of defined dimensions about the localizer and glide path antennas where vehicles, including aircraft, are excluded during all ILS operations. The critical area is protected because the presence of vehicles and/or aircraft inside its boundaries will cause unacceptable disturbance to the ILS signal-in-space.
|
|
b. The ILS sensitive area is an area extending beyond the critical area where the parking and/or movement of vehicles, including aircraft, is controlled to prevent the possibility of unacceptable interference to the ILS signal during ILS operations. The sensitive area is protected against interference caused by large moving objects outside the critical area but still normally within the airfield boundary.
18.2 The purpose of these procedures is to issue guidelines to ATCOs and officials of other agencies working at Jaipur Airport so as to ensure that the critical and sensitive areas of ILS are protected during low visibility operations as per the guidelines given below:
18.3 Protection of ILS Critical & Sensitive Areas:
18.3.1 ATCOs shall comply with the following guidelines for protection of Localizer Critical/Sensitive area during CAT II/IIIA/IIIB Operations:
18.3.1.1 Approach Control/Aerodrome Control Tower shall ensure that a succeeding arriving aircraft is cleared for CAT II or CAT IIIA or CAT IIIB ILS approach only after the:
a. Preceding arriving aircraft has landed and vacated the runway and is clear of localizer critical and sensitive Area or has carried out the missed approach procedure and has passed over localizer antenna.
b. Preceding departing aircraft is airborne and has passed over the localizer
antenna.
18.3.1.2 Arriving aircraft should be given un-impeded taxi route to allow it to clear
the localizer and Glide Path Critical and Sensitive area expeditiously.
18.3.1.3 The Localizer and Glide Path Critical and Sensitive area in front of an arriving aircraft shall not be infringed from the time the arriving aircraft crosses the Final Approach Point until it has completed its landing roll.
18.3.1.4 The ATCO’s shall activate the ILS Critical and Sensitive area map saved in the
ASMGCS.
18.3.2 After initiation of Safeguarding Procedures all civil/electrical works in progress shall be stopped immediately and men/material/equipment shall be removed from the sensitive/critical areas of localizer, glide path and OFZ.
18.3.3 After initiation of Safeguarding Procedures Apron Control/AOCC Supervisor
shall ensure that no unauthorized vehicle/person/material/equipment
enters or is present in the sensitive/critical areas of localizer and glide path.
