HSCA OCS Activation Rules for S16

HSCA Online Coordination System Activation Rules for S16

Updated on 08th July 2016

 

HSCA would like to announce new updated rules for Online Coordination System (OCS) for S16 scheduling period for all Coordinated (IATA Level 3) Greek Airports, which will be activated from 11th July 2016, 00:01  UTC.

 

A.    OCS is activated for all Coordinated (IATA Level 3) Greek Airports.

B.    Slot requests/changes/deletions of Ad Hoc flights can be handled through OCS as follows :

  • On every calendar (UTC) weekday for slot requests/changes/deletions of flights arriving on the day.
  • On weekends from Friday 00:01 UTC for slot requests/changes/deletions for flights with arrival horizon two days ahead, until Monday 23:59 UTC. 
  • On Greek Bank Holidays for slot requests/changes/deletions of flights arriving until next day 23:59 UTC.

C.     Closing hours of the airports that do not operate on 24 hours basis are not shown in OCS. Slot requests/changes outside the operating hours of these airports will be rejected by the system, therefore Air Carriers and GA/BA operators should be informed about the airport closing hours at HSCA site: http://www.hsca.gr/index.php/2014-12-08-10-22-54/operhrs

      The following rules shall apply for the Ad Hoc Slot Requests on OCS:

1.     Commercial Flights

  • Slot requests must be exclusively for Ad Hoc operations with requested arrival time within the time period of OCS activation specified above in B. 
  • Slot requests must be at least two (2) hours prior to the requested time of operation.
  • Slot requests with Ground time longer than two (2) hours will not be accepted.
  • Slot Requests in unlinked format will not be accepted, unless otherwise entitled.
  • Slot Requests for swaps will not be accepted

 

2.     GA/BA Flights

  • Slot requests must be exclusively for Ad Hoc operations with requested arrival time within the time period of OCS activation specified above in B. 
  • Slot requests must be at least two (2) hours prior to the requested time of operation.
  • Slot requests for GA/BA flights at all coordinated airports need a PPR (Prior Permission Required-parking authorization) in the SI section of the GCR message as per GA/BA coordination procedures:

                http://www.hsca.gr/index.php/8-mainpagearticles/29-gaba-coordination-process.

  • The PPR procedure applies also for changes of the already confirmed slots ONLY if changes in apron occupancy are more than 30 min. If apron occupancy changes are within the already confirmed timings, new PPR is NOT required. A new PPR is required in case of a higher category A/C type change.  
  • PPR procedure does not apply for GA/BA flights slot requests at Heraklion (LGIR) and Thessaloniki (LGTS) airports, when the requested ground time is up to two hours. For more than two hours ground time a PPR is needed for these airports also.
  • Requests in unlinked format will not be accepted.
  • The overnight indicator must be single digit only.
  • GIR requests are now available through OCS.

 

It is strongly recommended that OCS should be used by all Air Carriers and GA/BA operators interested in receiving immediate and valid responses to their Ad Hoc Slot Requests/Changes/Deletions.
