Transcript of A CDM

Finally
THE CDM CONCEPT
A- CDM
KEY ACHIEVEMENTS
The CDM principles
Common Situational Awareness (CSA) based on accurate and timely information
TAXIWAY
Operationalisation of TWY R (Reduced ROT by 10 secs for every a/c)
Optimizing airport facilities lies in the progressive adoption of a multi-partner operating model and Collaborative Decision-Making
In view of that Kolkata ATC had taken following steps
INITIATIVES
Clear decision, rules and agreed role and responsibilities
Awareness / warning when decision is lacking
MEETINGS WITH STAKEHOLDERS AND AIRPORT OPERATOR ARE CONDUCTED REGULARLY
Already in place for evaluation
Delays (TAXI-IN/ TAXI-OUT and holding point delay)
ROT
Approach speed
Implies reduced separation in arrival ( 7 miles on trial basis) matter under review in local CDM with the operators for standardization
R
19L
H1
Operationalisation of TWY H and J
( reduce bottleneck situation for entry to the apron )
J1
Creation of Taxilane joining F1 and A is under consideration
LVP

Provision of providing cat-II holding point at K is in progress
as K holding point does not come under critical and sensitive area of ILS kolkata.
RUNWAY 19L
ROT will decrease by 95 seconds for each departure. Therefore fuel saving will be more than 400 kg for 20 a/c ,so 20 kg /departure
Reduced ROT for departure resulting in reduction of Track mileage for arrival from 20 to 14 NM.

Approximate fuel saving for each arrival will be
50 kg and C0 emmision will reduce by 158 kg per aircraft
LVP statistics for last winter
provision of providing cat-II holding point at K is in progress as K holding point does not come under critical and sensitive area of ILS kolkata.
K
Approx fuel saving:
CO2 emission:
Number of operation:
ILS RUNWAY 19R
Implemented from Nov 2012
Enhanced the use of the airport in poor visibility condition whenever main RWY is taken under NOTAM
Transmissometer installed ,expected to be operational soon.
So further reduction of minima is expected
Simultaneous use of RWYs
The visibility criteria to use both the RWY can be reduced to 2500m from 3000m (
for departure from 19R without RWY lights
) enhancing the airport capacity.
Standard taxi route for arrival during simultaneous use of runways is formulated to avoid possible human error, implementation is under process
(
operators input pending
)
DCL
Pre-departure clearance issued on datalink before push back and start up clearance.
( Pre-departure clearance is given on voice on request in SMC freqn)
Matter taken up with operator for extensive use of DCL to reduce R/T congestion and enhance safety
Wrong RWY arrival averted: 04
A SMGCS
To enhance safety net increase in ASMGCS coverage towards app path is in progress
Kolkata Airport
Constraints
Parallel runways separated
by 213m
'A’ taxitrack is 116 m from the secondary RWY
A
19R
19L
19R
F
‘F’ apron taxilane extension is pending
No visual coverage for new apron and TXY F2
Only 1 apron taxilane is available in new apron
To overcome this issues steps are taken to enhance the use of airport as well as safety
Final Approach Spacing
Airport CDM Information Sharing
Variable Taxi
Time
Calculation
Collaborative
Pre-Departure
Sequencing
CDM in
Adverse
Conditions
Collaborative Management of Flight Updates
New Sector
Kolkata ACC has a new flexible sector called sector North
Benefits:
Reduce R/T congestion
Better utilization
of airspace
Enhanced safety
FUA
FLEXIBLE USE OF AIRSPACE OF BARRACKPORE AND KALAIKUNDA
BENEFIT :
Shorter Routing
Flexible routing during airspace closures due to Launching activity
Talks with IAF are on to use Kalaikunda Airspace whenever not in use by IAF
RHSM AND PBN
50-50 RHSM and PBN has resulted in fuel savings
Pending issues with Dhaka
RPL : flight operating from VECC to NE overflying Dhaka airspace is still pending ,awaiting approval from Dhaka.
Separate arrival and departure route for route B593 is proposed and agreed in bilateral meeting. Implementation awaited
Airport Information sharing
Field Stations
Let us tear down the walls between the airport partners and optimize the use of the airport
Culture change is the biggest challenge!
We will strive to achieve it
VEBS
24 hrs availability which helped to cater the diversion flights during low visibility at Kolkata
INDRA automation system type B will be installed shortly and an ADS B is also proposed in near future
VERC
INDRA automation system type A has been installed . Safety assessment ,training etc is completed conversion of controllers awaited
Work in progress to Increase the basic strip
VEPT
Huge Tree cutting had taken place and that helped to reduce obstructions in Approach funnel
TORA of RWY 07 has recalculated and has increased by 118m
INDRA automation system type B will be installed shortly and an ADS B is also proposed in near future
Basic strip has been graded
Topics
Fog Management
Road blocks related to fog was effectively handled in a collaborative manner
