0BEXECUTIVE SUMMARY

• February continued as January to perform with a steady growth of traffic and significant decrease of delays.

• The traffic experienced a 3.3% increase compared to the same month in 2010. This is in line with the

current 2011 yearly traffic forecast of 4.3%. • Compared to February 2010, ATFM delays decreased by 50.4%, confirming the trend observed since

November. The average delay per flight was 1.2 minutes, which is well below the Monthly Average Delay per flight during the last 13 months.

• Bad weather conditions particularly Ceiling, Low visibility and Wind were the main reason for ATFM delays

in February and accounted for 42.4% of all the Network delays. Frankfurt was the most affected airport followed by London Heathrow and Amsterdam.

• Significant ATC delays were recorded in Madrid, Langen, Paris, Prestwick, Canarias, Nicosia and Stockholm

ACC’s mainly due to ATC Capacity, Staffing and Equipment. • Istanbul continues to experience significant delays due to Aerodrome Capacity, however the situation is

improving following a significant increase in arrival capacity. • VAFORIT implementation in Karlsruhe UAC continued to have a significant impact. It is anticipated that

February is the last month when special measures for the transition to the new system will be required. • Highest delays occurred on the 5th of February due to Weather, ATC Staffing, ATC Capacity and VAFORIT

implementation. • 249 flights per day experienced ATFM delays in excess of 30 minutes (60% decrease), 302 flights

experienced ATFM delays in excess of 15 minutes (55% decrease). • Regarding ATFM slot adherence, the percentage of late departure decreased significantly compared to the

previous months. • Average en Route delay since the beginning of the year is 0.51 minutes per flight. This value is compatible

with the achievement of a 0.7 minutes En-route delay, provided the year continues with similar performance.

The traffic experienced a 3.3% increase compared to the same month in 2010.

As in January this figure overstates the underlying rate, which is closer to 2.5%, because of strikes in February 2010 causing cancellations. The same effect is probably responsible for pushing Germany and France ahead of Turkey in the list of which countries add most flights to the network.

The average daily traffic is above the level experienced in 2009 and 2010. The traffic increase for the rolling 12 months is 1.7%, but with a steady monthly acceleration of growth, which is consistent with the current 2011 yearly traffic forecast of 4.3%.

EUROCONTROL CFMU




Most airports continued to experience an increase in traffic. Ukraine and Turkey experienced the most significant increase in traffic. The most significant decrease of traffic was registered in Athens (-15.3%), London Stansted (-9.3%) and Palma (-7.1%). Both scheduled and low cost carriers continue to experience an increase in traffic: RYR (3%), EZY (9.7%), DLH (12.4%), and AFR (5.5%). The biggest increase was experienced by Pegasus Airlines (39.5%) and Cimber Air (25.2%). Aer Lingus (-11.1%), Aegean Airlines (-16%) and Czech Airlines (-17.4%) experienced a significant decrease in traffic. Unidentified operators (mainly General Aviation) recorded an increase of 0.1% in February.

All delays graph figures are represented as average minutes per day.

The average daily ATFM delays decreased from 59092 minutes in February 2010 to 29333 minutes in February 2011. Significant improvement can be highlighted and is mainly due to the fact that last February was significantly impacted by Industrial actions. February experienced a 50.4% decrease in delay compared to February 2010. The trend of ATFCM delay shows a regular decrease since November last year, disturbed by the adverse weather situation in December 2010. Meteo and ATC delays were the main reason for ATFM delays in February. Weather accounted for 42.4% of all the Network delays. Compared to 2010 Weather, ATC and Airport delays experienced a decrease. “Other” delays accounted for 7.7% of all ATFCM delays and were mainly due to VAFORIT implementation. The average overall ATFM delay per flight was 1.2 minutes like the previous month; this is well below the 2.6 minute average for the last 13 months.

Main delays were recorded in Frankfurt mainly due to weather (Wind) and airport capacity. Rhein UAC experienced significant delays due to “Other” reasons (VAFORIT). Amsterdam and London Heathrow experienced significant delays due to bad weather conditions. ATC Delays were recorded in Madrid, Nicosia, Warszawa, Paris, Langen and Canarias. Istanbul and Gran Canaria caused significant delays due to Aerodrome capacity.
