Issues taken up with management - 2006

 

CC/OPR-GEN/2006/3

Simultaneous use of converging RWY 27 and RWY 28

Sir,

The ATC Guild (India) has learnt that the management is contemplating forcing the ATCOs to make simultaneous use of converging RWY 27 and RWY 28 at IGI Airport by first week of April 2006. While the Guild is in agreement with the need to increase aircraft movements at IGI Airport, it apprehends that rushing in without taking care of necessary infrastructure is fraught with danger.

Runway 28 and 27 are converging runways. Simultaneous use of non-parallel (converging) runways is actively discouraged by ICAO; as such uses are fraught with danger. Such being the case, if Runway 27 and Runway 28 are to be used simultaneously, it becomes critically important to make good the limitations of resources and infrastructure (like trained manpower, development of procedures, proper ground infrastructure and automation tools to preempt risks) before such a move is contemplated.

The Guild wishes to point out the following issues and bottlenecks that will arise with simultaneous use of Runways 27 and 28 at IGI Airport:

  1. Simultaneous use of runways will lead to Active Runway crossings by arriving aircraft from taxiway ‘Y’ to taxiway ‘C’; which will lead to increase in runway incursion incidents.

  2. An aircraft crossing the Runway towards taxiway ‘C’ will be unable to give runway vacation report as there is no marking for the pilot (signage) to do so.

  3. The Controller will have to bear increased stress and is likely to commit costly mistakes by giving landing clearances, when an aircraft is crossing the active runway.

  4. Additional Conflict Points will be created on the domestic apron between departures and arriving aircraft at taxiway ‘B’ and taxiway ‘C’ intersection.

  5. Our controllers have no experience of working in such environment. The lack of experience will lead to Controllers going for larger separations, thus defeating the whole purpose of simultaneous operations.

  6. Simultaneous use of runways will require increase in working positions / stations in Tower, Surface Movement Control and Approach radar. IGI Airport is not suitably equipped to sustain the load vis-à-vis trained manpower availability.

The Guild therefore emphasizes undertaking the following measures before simultaneous use of runways are permitted:

A safety-study with focus on Risk Analysis and Management for simultaneous use of converging runways has not been done yet. This study must be carried out immediately.

Controllers at IGI Airport are not conversant with simultaneous use of converging runways. No programme has been chalked out yet for familiarization and training of Controllers to manage simultaneous use of runways. Extensive training of Controllers must be carried out before using the converging runways simultaneously.

Ground infrastructure like construction of parallel taxiways circumventing the runways has to be completed before permitting simultaneous use of runways. Unless this is done, aircraft will have to cross the active runway and incidents of runway incursions will increase.

The bottleneck issues pointed out above will, in the opinion of the Guild, actually reduce the number of movements at IGI Airport instead of increasing it as is being contemplated.

With Regards,

R K Singh
