10 Significant Events (1) Tuesday, 3 July UTC: Emergency maintenance of Rapid Exit Taxiway E13 resulting in reduced capacity UTC: Emergency maintenance of remaining portion of Runway 19L resulting in reduced capacity UTC: Convective weather condition reducing capacity, resulting in 1 diversion 9 Jul

11 Significant Events (2) Wednesday, 3 July UTC: Closure of remaining portion of Runway 19L due to emergency maintenance of Taxiway B11 resulting in reduced capacity UTC: Convective weather resulting in 1 diversion UTC: Closure of remaining portion of Runway 19L due to Takeoff Position damage resulting in reduced capacity 9 Jul

12 Significant Events (3) Thursday, 4 July UTC: Emergency closure of Western Runway 19R due to surface damages resulting in 12 diversions and 2 aircraft declaring emergency due to fuel shortage UTC: Emergency maintenance of remaining portion of Runway 19L resulting in reduced capacity and additional airborne delay for 3 aircraft 9 Jul

13 Overall Summary Cooperation in accordance to published Departure / Arrival Time Window would help reduce workload and disruption for all involved More fluctuation of arrivals in accordance to Arrival Time Window and arrivals attempting to comply but ended up operating later than Arrival Time Window Week 3: percent Week 4: percent There appears to be correlation between significantly low Arrival Compliance on Saturday, 7 July 2012 (27 percent) and Sunday 8 July 2012 (32 percent) with significant increase of airborne delay 9 Jul

14 Overall Summary Readiness of runway, taxiway, signage affects overall aerodrome capacity In case of emergency maintenance, all involved need to be notified as soon as practicable Airborne delay continued to be lower than ground delay Ground delay managed at aircraft stand with engines off in accordance to Gate Hold Procedure Arrivals given priority to alleviate airborne delay, reducing need for diversions 9 Jul

15 Overall Summary More collaborative exchange of information among airport operators, aircraft operators and ANSPs could assist in minimizing operational impact of the maintenance Single-Runway Capacity of 34 movements/hour in line with operational results Delay advisory provided in line with operational results < Feedback from the airlines indicated that delays forecasted were in line with operational results 9 Jul

16 Recommendation Airport Collaborative Decision Making (Airport CDM) should be implemented to facilitate speedier exchange of situation such as planned off-block readiness, weather pattern, airport surface conditions in order to reduce operational workload and enhance operational efficiency Weather forecast, surface conditions should be provided in advance to all involved for pre-tactical planning Tactical system should be able to actively distinguish those operating in accordance to plan from others to provide incentive to operate in accordance to plan Communications with all involved continue to be necessary 9 Jul
