II. AIRPORT COLLABORATIVE DECISION MAKING (A-CDM, SARDAR VALLABH BHAI PATEL

INTERNATIONAL AIRPORT, AHMEDABAD)

1. BACKGROUND

1.1 Sardar Vallabh Bhai Patel International Airport, Ahmedabad - Collaborative Decision Making (A-CDM, Ahmedabad) undertaken at Sardar Vallabh Bhai Patel International Airport is a joint programme among all airport partners -

• Air Navigation Service Provider (ATC)

• Aircraft Operators (AO)

• Airport Operator / (AOCC)

• Ground Handling Agencies (GHA)

• Central Air Traffic Flow Management Unit (CATFMU)

• Air Force Movement Liaison Unit (AF-MLU)

All the partners are required to work in close collaboration to ensure the successful operation of A-CDM, Ahmedabad.

1.2 The efficiency of the Air Transport System is highly dependent on traffic predictability. A-CDM, Ahmedabad effectively enhances predictability (this reduces buffer times for resource planning and flight times), overall efficiency and punctuality by linking and sharing of accurate and timely information amongst Aircraft Operators, Airport Operator, ATC, etc.

1.3 A-CDM application is developed in-house by Airports Authority of India.

1.4 A-CDM system processes and utilizes the following information from the various sources mentioned below:

a) AFTN:

i) Flight plan data

ii) EOBT

iii) ATD

iv) ETA

v) NOTAM

vi) METAR

vii) ADC Number

b) Airport Operations Data Base (AODB) of Ahmedabad

i) Parking stand of Aircraft

ii) Aircraft registration

iii) Boarding status of departing aircraft

iv) Actual “Off Block” Times (AOBT)

v) Actual “In-Block” Times (AIBT)

c) A-CDM system database

i) Arrival and Departure Taxi timings from each parking stand

ii) Runway-in-Use and Closures

iii) Hourly handling capacity of runways

iv) Priority of flights e.g. VVIP and Emergencies etc.

v) Flight schedules

1.5 A-CDM is a Common Information Sharing Platform introduced to process timely and accurate information for quick and precise decision making. A-CDM takes into consideration the ETAs of arriving aircraft, Target Off Block Times (TOBT) of departures, Runway-in-use and the handling capacity of the runway and determines the arrival and departure sequence. Based on the sequence and the parking position, it calculates the Target Take-Off Times (TTOT) & Target Start up Times (TSAT)of departures and Target In-Block Times (TIBT) for arrivals.

1.6 Implementation of ACDM will result in considerable benefits to stakeholders. The various benefits of A-CDM includes are as follows:

• Improvement in efficiency of operations

• Reduction of delays to departures at holding point.

• Orderly flow of traffic.

• Reduction in wastage of Aviation fuel.

• Reduction in Carbon footprint, reduction in Environmental Pollution.

• Optimization of airport and airspace capacity

• Reduction in R/T congestion

• Enhanced efficiency and reduced workload due to reduced R/T congestion.

• Improved Situational Awareness and increased confidence amongst ACDM Partners.

• Adherence to ADC (Air Defence Clearance) by stake holders.

2. TWO KEY PARAMETERS OF A-CDM, AHMEDABAD: TOBT and TSAT.

2.1 TARGET OFF-BLOCK TIME (TOBT)

2.1.1 Definition: The time that an Aircraft Operator estimates that an aircraft will be ready, all doors closed, boarding bridge removed, push back vehicle available and ready to start up/push back immediately upon reception of clearance from the Surface Movement Control Unit SMC (R/T Callsign: Ahmedabad Ground). It is the real time target of ensuring readiness of an aircraft and therefore, more accurate than the static departure time mentioned in the flight plan and hence, an ideal milestone to be used by all airport partners.

2.1.2 Purpose: Air Traffic Management (ATM) based on only FPL-data is insufficient to guarantee smooth and efficient operations on the ground and in the air. The main reason for this is the incorrect updating/no updating at all, of the Estimated Off Block Time (EOBT) of the aircraft. The result is that airport partners will have an incorrect idea about the actual status of that specific aircraft. The purpose of Target Off-Block Time (TOBT) is to provide a timely, accurate and reliable estimate of an aircraft's off block time to the A-CDM, Ahmedabad partners. Accurate TOBTs enhance operations on the ground as they provide all airport partners with a clear picture of the intentions of aircraft on the ground.

2.1.3 Communication of TOBT: Aircraft Operators shall revise their EOBTs via AFTN using CHG/ DLA message or inform ARO for revised EOBT, who in turn will originate CHG / DLA message for transmission through AFTN.

2.1.3.1 In case No delay is expected: If there is no revision of EOBT, EOBT will be treated as the TOBT. For such cases there is no need of any communication from the Aircraft Operator to the ARO.

2.1.3.2 In case delay is expected:

a) When Air Defence Clearance (ADC) is valid: If delay is within the validity period of ADC, EOBT should be revised through CHG/DLA message. Optionally TOBT can be changed in ACDM interface. But if due to some reason coordination is not possible by both the above methods then EOBT can be revised by informing ARO.

b) When Air Defence Clearance ADC is NOT valid:

i) If delay is outside the validity period of ADC, EOBT shall be revised through CHG/DLA message or after having coordinated with MLU and obtaining the revised ADC number, by informing ARO about revised EOBT and ADC. (Option of change of TOBT will not be available in this case).

ii) ADC Validity Period: (-) 15 minutes to (+) 45 minutes of EOBT in RPL/FPL or subsequent revision of EOBT by DLA/CHG message.

Note: Once Target Start-up Approval Time (TSAT) is allocated by ATC at TOBT - 30 minutes, the TOBT can be updated thrice

2.1.5 Accuracy: TOBTs must be updated to an accuracy of +/- 5 minutes.

2.2 TARGET START UP APPROVAL TIME (TSAT)

2.2.1 Definition: The time is calculated by A-CDM application taking into account TOBT, CTOT* and/or the traffic situation that an aircraft can expect to start-up/push back for departure.

Note: In case there is no congestion, ATC may allow the aircraft to start, where Actual Start-up Approval Time (ASAT) will be before the TSAT.

2.2.2 Purpose: TSATs provide an optimized start-up sequence, leading to Pre-Departure sequence. TSATs reduce queuing times at the runway holding points, while ensuring optimised utilisation of the runway. ATC will continue to optimize the departure order for creating the right mix of traffic.

2.2.3 Calculation of TSAT: TSAT is calculated automatically by A-CDM Application. The TSAT is calculated by taking into account TOBT, priority of aircraft, variable taxi times (VTT), and the runway capacity. Any revision of EOBT will trigger the A-CDM application to recalculate a new TSAT for that flight as well as to re-allocate earlier TSAT to next flight which meets the requisite conditions. TSAT is displayed in various ACDM interfaces in the following colour coded information.

Blue colour: TSAT - 15 minutes up to TSAT - 5 minutes; Green colour: TSAT - 5 minutes up to TSAT + 5 minutes; Red colour: After TSAT + 5 minutes.

2.2.4 Generation of TSAT: TSAT is generated by ACDM interface at TOBT - 30 minutes.

2.2.5 Communication of TSAT: TSAT will be displayed in various A-CDM interfaces.

The AO/GHA shall advise flight crew of TSAT, displayed in the A-CDM interface.

2.2.6 Priorities for generation of TSAT:

The following aircraft will be accorded priority by A-CDM application at the time of generating TSATs:

a) VVIP flights

b) Aircraft in emergency

c) Ambulance aircraft

d) Aircraft in relief missions

e) Aircraft returning to stand after push back/taxiing out for any reason.

f) The flights, in addition to the above, that require special handling with status in item 18 of Flight plan as:

i. ATFMX: flight approved for exemption from ATFM measures by the appropriate ATS authority;

ii. FFR: fire-fighting;

iii. FLTCK: flight check for calibration of navaids;

iv. HOSP: medical flight declared by medical authorities;

v. HUM: flight operating on a humanitarian mission;

vi. MEDEVAC: life critical medical emergency evacuation;

vii. SAR: flight engaged in a search and rescue mission

2.2.7 Airlines/GHAs are required to monitor the A-CDM interface regularly to get information on the revised TSAT if any, in respect of their aircraft. It may please be noted that the earlier allocated TSAT may get changed due to the following reasons:

i. Change of runway

ii. Change in taxi times

iii. Revised TOBT of the subject aircraft

iv. Cancellation/ revision in TOBT of other aircraft in the departure sequence.

v. Priority handling

vi. Unusual Occurrences, etc.

vii. Change of aircraft type*

viii. Application of ATFM regulation or ATC restriction resulting in new CTOT or start up delay*

ix. Inclement Weather*

x. Bird activity*

xi. Change of route (SID)*

2.2.8 Accuracy: The TSAT will remain valid for +/- 5 minutes.

3 CO-ORDINATION WITH THE CENTRAL AIR TRAFFIC FLOW MANAGEMENT UNIT (CATFMU)*

3.1 A permanent and fully automatic data exchange with the ATFMU will be established. The data transfer will enable highly accurate early predictions of landing and departure times.

3.2 Furthermore, it allows for more accurate and efficient CTOT calculations due to the use of more accurate local target take-off times. *

4. TOBT AND TSAT BASED A-CDM, AHMEDABAD START-UP/PUSH-BACK PROCEDURES

4.1 Pre-Departure Sequence: Pre-Departure sequence is the order, in which the ATC plans the aircraft to depart from their

Gate/Stands. It should not be confused with the Pre-Takeoff sequence where ATC decides on the order in which the aircraft at holding points of the runway will depart.

4.2 Start-Up and Push-Back Procedure:

i. The pilot will contact SMC Unit (GROUND) to request en-route clearance and SID between TSAT - 15 minutes to TSAT - 5 minutes. Blue Zone.

ii. The aircraft must be ready to Start-up/Push-back at TOBT and request SMC (GROUND) for Start-up/Push-back at TSAT - 5 minutes and TSAT + 5 minutes. Green Zone.

(Note: The system may prepone TSAT up to TOBT)

iii. In case for Schedule Flight, “Boarding” has not started at or before TSAT - 5 Minutes, allotted TSAT will be cancelled and associated slot will be allocated to next eligible aircraft.

a. A new TOBT is required from Airlines Operator.

b. On receipt of new TOBT, the flight will be re-sequenced according to new TOBT and a new TSAT with a subsequent delay will be issued.

iv. If at TSAT +5 minutes: Red Zone, ATC has not received Start-up / Pushback request, the aircraft will lose its position in sequence.

a. A new TOBT is required from Airlines Operator.

b. On receipt of new TOBT, the flight will be re-sequenced according to new TOBT and a new TSAT with a subsequent delay will be issued

v. ATC should normally be able to issue start-up/push-back at TSAT. Pilots will be informed by ATC of any revised TSAT if there is a delay to TSAT in excess of 5 minutes.

vi. Taxi clearance must be requested within 5 minutes of Start-up/Pushback approval time.

(Note: If this has not occurred, SMC (GROUND) must be notified of the extent of delay. In such cases, aircraft may lose its departure slot and a new TOBT may be required in A-CDM, Ahmedabad interface. AO shall be responsible to obtain newADC number from IAF-MLU)

vii. The Pre-Departure (Off- block) Sequence will be determined in accordance with Target Start up Approval Time (TSAT) and NOT in accordance with the Start-up Request. Pre-Departure Sequence will not have any bearing on Actual Departure sequence.

(Note: Actual Departure sequence may differ from pre-departure sequence in order to optimize the Runway and Airspace utilization.)

• Aircraft Operators (AO)

• Airport Operator / (AOCC)

• Ground Handling Agencies (GHA)

• Central Air Traffic Flow Management Unit (CATFMU)

• Air Force Movement Liaison Unit (AF-MLU)

All the partners are required to work in close collaboration to ensure the successful operation of A-CDM, Ahmedabad.

1.3 A-CDM application is developed in-house by Airports Authority of India.

1.4 A-CDM system processes and utilizes the following information from the various sources mentioned below:

a) AFTN:

i) Flight plan data

ii) EOBT

iii) ATD

iv) ETA

v) NOTAM

vi) METAR

vii) ADC Number

b) Airport Operations Data Base (AODB) of Ahmedabad

i) Parking stand of Aircraft

ii) Aircraft registration

iii) Boarding status of departing aircraft

iv) Actual “Off Block” Times (AOBT)

v) Actual “In-Block” Times (AIBT)

c) A-CDM system database

i) Arrival and Departure Taxi timings from each parking stand

ii) Runway-in-Use and Closures

iii) Hourly handling capacity of runways

iv) Priority of flights e.g. VVIP and Emergencies etc.

v) Flight schedules

1.6 Implementation of ACDM will result in considerable benefits to stakeholders. The various benefits of A-CDM includes are as follows:

• Improvement in efficiency of operations

• Reduction of delays to departures at holding point.

• Orderly flow of traffic.

• Reduction in wastage of Aviation fuel.

• Reduction in Carbon footprint, reduction in Environmental Pollution.

• Optimization of airport and airspace capacity

• Reduction in R/T congestion

• Enhanced efficiency and reduced workload due to reduced R/T congestion.

• Improved Situational Awareness and increased confidence amongst ACDM Partners.

• Adherence to ADC (Air Defence Clearance) by stake holders.

• Better Passenger experience.

• Optimized use of ground handling resources

• Optimized use of parking stands, gates and terminals.

• Reduced apron and taxiway congestion

• Access to current MET information.

2. TWO KEY PARAMETERS OF A-CDM, AHMEDABAD: TOBT and TSAT.

2.1 TARGET OFF-BLOCK TIME (TOBT)

2.1.3.1 In case No delay is expected: If there is no revision of EOBT, EOBT will be treated as the TOBT. For such cases there is no need of any communication from the Aircraft Operator to the ARO.

2.1.3.2 In case delay is expected:

b) When Air Defence Clearance ADC is NOT valid:

ii) ADC Validity Period: (-) 15 minutes to (+) 45 minutes of EOBT in RPL/FPL or subsequent revision of EOBT by DLA/CHG message.

Note: Once Target Start-up Approval Time (TSAT) is allocated by ATC at TOBT - 30 minutes, the TOBT can be updated thrice

2.1.5 Accuracy: TOBTs must be updated to an accuracy of +/- 5 minutes.

2.2 TARGET START UP APPROVAL TIME (TSAT)

2.2.1 Definition: The time is calculated by A-CDM application taking into account TOBT, CTOT* and/or the traffic situation that an aircraft can expect to start-up/push back for departure.

Note: In case there is no congestion, ATC may allow the aircraft to start, where Actual Start-up Approval Time (ASAT) will be before the TSAT.

Blue colour: TSAT - 15 minutes up to TSAT - 5 minutes; Green colour: TSAT - 5 minutes up to TSAT + 5 minutes; Red colour: After TSAT + 5 minutes.

2.2.4 Generation of TSAT: TSAT is generated by ACDM interface at TOBT - 30 minutes.

2.2.5 Communication of TSAT: TSAT will be displayed in various A-CDM interfaces.

The AO/GHA shall advise flight crew of TSAT, displayed in the A-CDM interface.

2.2.6 Priorities for generation of TSAT:

The following aircraft will be accorded priority by A-CDM application at the time of generating TSATs:

a) VVIP flights

b) Aircraft in emergency

c) Ambulance aircraft

d) Aircraft in relief missions

e) Aircraft returning to stand after push back/taxiing out for any reason.

f) The flights, in addition to the above, that require special handling with status in item 18 of Flight plan as:

i. ATFMX: flight approved for exemption from ATFM measures by the appropriate ATS authority;

ii. FFR: fire-fighting;

iii. FLTCK: flight check for calibration of navaids;

iv. HOSP: medical flight declared by medical authorities;

v. HUM: flight operating on a humanitarian mission;

vi. MEDEVAC: life critical medical emergency evacuation;

vii. SAR: flight engaged in a search and rescue mission

i. Change of runway

ii. Change in taxi times

iii. Revised TOBT of the subject aircraft

iv. Cancellation/ revision in TOBT of other aircraft in the departure sequence.

v. Priority handling

vi. Unusual Occurrences, etc.

vii. Change of aircraft type*

viii. Application of ATFM regulation or ATC restriction resulting in new CTOT or start up delay*

ix. Inclement Weather*

x. Bird activity*

xi. Change of route (SID)*

2.2.8 Accuracy: The TSAT will remain valid for +/- 5 minutes.

3 CO-ORDINATION WITH THE CENTRAL AIR TRAFFIC FLOW MANAGEMENT UNIT (CATFMU)*

3.1 A permanent and fully automatic data exchange with the ATFMU will be established. The data transfer will enable highly accurate early predictions of landing and departure times.

3.2 Furthermore, it allows for more accurate and efficient CTOT calculations due to the use of more accurate local target take-off times. *

4. TOBT AND TSAT BASED A-CDM, AHMEDABAD START-UP/PUSH-BACK PROCEDURES

4.1 Pre-Departure Sequence: Pre-Departure sequence is the order, in which the ATC plans the aircraft to depart from their

Gate/Stands. It should not be confused with the Pre-Takeoff sequence where ATC decides on the order in which the aircraft at holding points of the runway will depart.

4.2 Start-Up and Push-Back Procedure:

i. The pilot will contact SMC Unit (GROUND) to request en-route clearance and SID between TSAT - 15 minutes to TSAT - 5 minutes. Blue Zone.

ii. The aircraft must be ready to Start-up/Push-back at TOBT and request SMC (GROUND) for Start-up/Push-back at TSAT - 5 minutes and TSAT + 5 minutes. Green Zone.

(Note: The system may prepone TSAT up to TOBT)

iii. In case for Schedule Flight, “Boarding” has not started at or before TSAT - 5 Minutes, allotted TSAT will be cancelled and associated slot will be allocated to next eligible aircraft.

a. A new TOBT is required from Airlines Operator.

b. On receipt of new TOBT, the flight will be re-sequenced according to new TOBT and a new TSAT with a subsequent delay will be issued.

iv. If at TSAT +5 minutes: Red Zone, ATC has not received Start-up / Pushback request, the aircraft will lose its position in sequence.

a. A new TOBT is required from Airlines Operator.

b. On receipt of new TOBT, the flight will be re-sequenced according to new TOBT and a new TSAT with a subsequent delay will be issued

v. ATC should normally be able to issue start-up/push-back at TSAT. Pilots will be informed by ATC of any revised TSAT if there is a delay to TSAT in excess of 5 minutes.

vi. Taxi clearance must be requested within 5 minutes of Start-up/Pushback approval time.

(Note: Actual Departure sequence may differ from pre-departure sequence in order to optimize the Runway and Airspace utilization.)

1. INTRODUCTION

1.1 For RNAV(GNSS/DME-DME-IRU) SIDs and STARs operations, the aircraft shall be GNSS/DME-DME-IRU equipped and the navigation systems shall meet ICAO RNAV-1 standard of accuracy or equivalent.

1.2 Operators/pilots who are not approved to fly the RNAV(GNSS/DMEDME-IRU) SIDs and STARs shall fly the conventional SIDs or expect radar vectors from ATC.

2. ARRIVALS

2.1 STARs are presented in diagrammatic format on a chart which comprises two main elements:

a) A TRANSITION route; and

b) An ARRIVAL route.

2.2 A TRANSITION starts at a waypoint on the ATS route and then requires VOR/DME or RNAV tracking to position the aircraft for the ARRIVAL route.

2.3 All arriving aircraft are required to follow the appropriate TRANSITION and ARRIVAL routes.

2.4 Additional elements on the STAR chart include the following:

a) Vertical restrictions - designed to contain aircraft in controlled airspace and to separate aircraft from obstacles and to

avoid, to the degree possible, conflict with departing traffic.

b) Speed restrictions - designed for flow control purposes.

c) Minimum safe altitude (MSA) - provides a minimum clearance of 1000Ft above all objects located in an area contained

within 25NM of AAE VOR.

2.5 Arrivals can expect radar vectors to intercept the localizer for an ILS approach from the RNAV STARs.

2.6 STARs shall be issued by ATC in the following order:

a) ARRIVAL identifier;

b) TRANSITION identifier;

c) Runway-in-use;

d) An assigned level

2.7 Holding

a) AH393 - 1 min left hand race track pattern, inbound track 215 deg M, minimum holding altitude 9000Ft

9. LOW VISIBILITY PROCEDURES :

9.1 BACKGROUND:

Until the latest amendment of DGCA Civil Aviation Requirements (CAR) Section 8, Series 'C', Part-1 on All-weather Operations, low visibility procedures were required at aerodromes for the purpose of ensuring safe operations during categories 2 and 3 approaches and/or low visibility take-offs (LVTO). However, in latest amendment to CAR (Rev. 10) Para 5.3 following provision regarding low visibility procedures is added. 'An operator shall not conduct take-off with RVR/visibility less than standard category 1 conditions of 550M RVR/800M visibility unless low visibility procedures are enforced.' This provision necessitated the need of low visibility procedures for accommodating/permitting departures in visibility/RVR less than 800M/550M even at such airports where there are no CAT-II and CAT-III operations. Accordingly, low visibility procedures have been developed for Sardar Vallabh Bhai Patel International Airport, Ahmedabad to accommodate/permit departures in visibility/RVR less than 800M/550M from RWY 23 (runway served with RVR instruments).

9.2. DEFINITIONS:

9.2.1 Low Visibility Procedures (LVP): Specific procedures applied at an aerodrome for the purpose of ensuring safe operations during Categories II and III approaches and/or low visibility take-offs.

Note: as per para 5.3 of CAR on All Weather Operations, an operator shall not conduct Take-off with RVR/Visibility less than standard CAT-I conditions of 550m RVR/800m Visibility unless low visibility procedures are enforced.

9.2.2 Manoeuvring Area: That part of an aerodrome to be used for the take-off, landing and taxiing of aircraft, excluding aprons.

9.2.3 Runway Visual Range: The range over which the pilot of an aircraft on the centerline of a runway can see the runway surface markings or the lights delineating the runway or identifying its centreline.

9.2.4 Aerodrome Operating Minima: The limits of usability of an aerodrome for:

a. take off, expressed in terms of runway visual range and / or visibility and, if necessary, cloud conditions.

b. landing in 2D instrument approach operations, expressed in terms of visibility and/or runway visual range; minimum descent altitude/height (MDA/H) and, if necessary, cloud conditions; and

c. landing in 3D instrument approach operations, expressed in terms of visibility and/or runway visual range and decision altitude/height(DA/H) appropriate to the type and/or category of the operation.

9.2.5 Visibility: Visibility for aeronautical purposes is the greater of: a. The greatest distance at which a black object of suitable dimensions, situated near the ground, can be seen and recognized when observed against a bright

background;

b. The greatest distance at which lights in the vicinity of 1,000 candelas can be seen and identified against an unlit background.

Note 1. -- The two distances have different values in air of a given extinction coefficient, and the latter b) varies with the background illumination. The former a) is represented by the meteorological optical range (MOR).

Note 2. -- The definition applies to the observations of visibility in local routine and special reports, to the observations of prevailing and minimum visibility reported in METAR and SPECI and to the observations of ground visibility.

9.3. GENERAL:

The Low Visibility Procedure (LVP) incorporates safeguarding measures to mitigate runway incursions and defines operational restrictions to ensure safe Airside Operations taking into account the available Aerodrome facilities.

9.4. MINIMUM REQUIREMENTS:

The following Aeronautical Ground lights and RVR equipment shall be serviceable to the required standard to support Low Visibility Procedures:

a. Runway edge lights,

b. Runway end lights,

c. Real time TDZ RVR.

d. Stand by Power supply to maintain switch over time of 1 Second for Runway

Edge Lights and Runway End Lights. This requirement can be met with the help of DG Set and/or UPS.

9.4.1 Unserviceability of Aeronautical Ground Lights/ Equipment before Implementation of LVP.

Low Visibility Procedures will not be implemented when any of the light/equipment mentioned in para 4 above is un-serviceable or is not maintained as per the required standard.

Aeronautical Ground Lighting Facility	Un-serviceability	Restrictions
Runway Edge lights	More than 15% of all lights are unserviceable	LVP operations will be suspended.
Runway Edge lights	Any two consecutive lights or more are unserviceable	LVP operations will be suspended.
Runway End lights	More than 15% of all lights are unserviceable	LVP operations will be suspended.
Runway End lights	Any two consecutive lights or more are unserviceable	LVP operations will be suspended.
Standby Generators/UPS	Any of the generator/UPS is unserviceable	LVP operations will be suspended.

9.4.2 Unserviceability of Aeronautical Ground Lights/ Equipment after Implementation of LVP.

When any of the light/equipment mentioned in para 4 above becomes un-serviceable or fails to meet the required standard during periods of LVP, TWR/SMC shall advise the aircraft accordingly and LVP shall be suspended and information to this effect shall be included in ATIS broadcast.

9.5. SAFEGUARDING PROCEDURES:

Safeguarding Procedures (SP) are instructions for relevant airport, departments and airside operators to prepare ground services and facilities for low visibility operations in order that when LVP are implemented all safeguarding procedures are complete. Duty Officer Tower/Tower Supervisor will initiate and co-coordinate with all the concerned agencies for completion of safeguarding procedures before implementation of Low Visibility Procedures.

9.5.1 Safeguarding Procedures shall be initiated when:

a. The Visibility/RVR is less than 1200m and visibility/RVR is forecast to deteriorate to 800m or less; and/or

b. The cloud ceiling is less than 400ft and forecast to fall to 200ft or less.

9.5.2 Safeguarding procedures include:

a. Positioning of 1 CFT each at the two predetermined positions at Glide path RWY 23 and at fire approach road near TWY Delta.

b. Stopping of all maintenance works on the manoeuvring area as well as removal of all men and mobile equipment from the said area.

c. Ensuring availability of secondary power supply for change over time of maximum one second for RWY Edge and RWY End lights supported by UPS.

(NOTE: RWY Edge and Rwy End lights may continue to operate on main power supply during safeguarding Procedures. Whenever, LVP is to be implemented as per para 6 below, the RWY Edge and RWY End lights shall be put on Standby Power Supply (DG set or UPS). This operation need to be completed before LVP is implemented.

(As UPS is available at Sardar Vallabh Bhai Patel International Airport, Ahmedabad and is capable of maintaining the required AGL system (refer table under para 4.1) with one second of Switch Over time with Main Supply, the main supply can continue to be primary supply and the Generator Supply can be kept as Standby Power supply. In case of UPS is unserviceable, Generator supply will become primary source of power supply and Main power supply shall act as standby power supply.)

d. The appropriate Aeronautical ground lights must have been inspected during the hour preceding implementation of LVP, and thereafter once every two-hour period. These lighting inspections should be accorded priority and, if necessary, aircraft operations may be delayed.

9.6. LOW VISIBILITY PROCEDURES:

9.6.1 Implementation of Low Visibility Procedures:

SMC shall inform Duty Officer Tower controller whenever Visibility/RVR reduces to 800 Meters or below and/ or cloud ceiling is at 200 ft or below. Tower supervisor shall coordinate with all the agencies to confirm whether the Safeguarding procedures have been completed or not. When Visibility/RVR falls below 800m/550M and or Cloud Ceiling is 200 ft or below and safeguarding procedures are complete, Tower supervisor will implement Low Visibility Procedures. Duty Officer Tower shall inform all users of the imposition of low visibility procedures.

9.6.2 Action by various units during LVP:

a. Duty MET Officer shall keep Duty Officer Tower informed of any change in Visibility/ RVR.

b. SMC shall ensure that the towing of aircraft is done under escort of “Follow Me” vehicles. “Follow Me” shall follow the route cleared by ATC;
