Mumbai’s Challenge

Convergence of Traffic

Flight Plan –

Not available/ Aircraft not

on FPL track

Aircraft switching routes

in Oceanic airspace

Military identificationMumbai has Oceanic (Remote) and Continental (Surveillance) Airspace

1. Advisory NOTAM to avoid Pakistan Airspace2. Traffic Orientation Scheme3. Negotiation with Military for opening additional routes 4. Opening of Domestic Routes for International overflying5. H24 operation of N5636. Regular Stakeholder communication / clarification7. Flow control measures at Departure aerodromes8. Traffic flow streamlining by downstream ACC9. Reroute plan for aircraft in flight10.Additional manpower11.Daily analysis of Traffic flow in coordination with ATFM team

Actions Taken

Way Forward

1. Safety of Aircraft is more important than schedule2. Even in contingency, aircraft to follow AIP / ATM instructions3. R/T Discipline4. Cooperation from all stakeholders for the initial 72 hrs on 1 to 3 above5. Suggestions should be based on possible implementation in prevalent

scenario adhering to ICAO safety standards6. Coordinated flow control measures across FIRs7. Collaborative new airspace restrictions like FLAs8. Mutual Support / Trust on capabilities of neighbouring ANSPs who are

managing the overloaded traffic density exceeding the capacity

ANSP expectation

Define Stakeholder actions for the first 48 / 72 hrs Agree minimum navigation requirements and priority rulesFlow control at all departure aerodromeRegulating traffic downstream for convergence upstream Identify Capacity of each major traffic flow routes particularly those

across ICAO Regions (Annex 11 Attachment C)A forum for states at the interface of ICAO regions (AAMA-SCM/

RDGE)

Future considerations

DOC 9689 on separation minima: Para 6.12 “ The longitudinal collision risk is also dependent on the typical along-track navigational performance, which determines the likelihood that longitudinal separation will be lost. Therefore, it is important to constrain the along-track performance of the aircraft population……. The accuracy of position measurement can be controlledby selecting an RNP value.

[Navigation specification (PBN) may be agreed between Regions for implementation by states at the regional interface.]
