4 Croatia Basic facts and figures Croatia 4.5 million citizens Total of 300 aircraft in register / 3 operators of transport category aircraft 9 international airports : 1 airport that handles more than 2 mil. passengers anually (ZAG / 2014) 2 airports that handle more than 1 mil. passengers annually, (SPU / DBV / 2014) Croatian airports under EASA Scope: 6+3=9 (Mali Lošinj, Osijek, Brač: VFR) Cluj, Romania, Sept /60

5 Croatia Basic facts and figures Ministry of Maritime Affairs, Transport and Infratsructure Croatian Civil Aviation Agency Aircraft Accident & Incident Investigation Agency Civil Aviation Industry Responsibilities Air Traffic Act, Article 4 Responsibilities Air Traffic Act, Articles 5-11 Responsibilities Air Traffic Act, Article 12 Croatian Civil Aviation System Cluj, Romania, Sept /60

6 The airport certification process in Croatia based on ICAO Doc (1) February 2005 / The Ordinance on conditions to be met by airport operator for issuing and manner of issuance of Airport Certificate (Ordinance on Airport Certification) marked the beginning of airport certification process in the Republic of Croatia on the basis of ICAO Doc (2) The first version of the Ordinance on Airport Certification consisted of 17 articles. The most important were three of them: 3rd, 11th and 14th. Cluj, Romania, Sept /60

7 The airport certification process in Croatia based on ICAO Doc Article 3 Airport Manual 2 copies and the minimum of 5 years experience (in aviation) of airport manager Article 11 Contents of Airport Manual 5 chapters: General conditions Airport location Aeronautical data Airport operations ( sub-chapters) SMS Article 14 Airport operator obligation to ensure implementation of standards and recommendations of ICAO Annex 14 Cluj, Romania, Sept /60

8 The airport certification process in Croatia based on ICAO Doc The essential features of this process of airport certification were as follows: The center of interest was the ability of airport operator to manage the airport, The lack of appropriate instructions no workshops were provided, the timeline for certification process was six months from the date of publication of the Ordinance (?!), The lack of quality coordination of the process Each airprot operator understood the contents of the Airport manual in his own way, Although being one of the conditions, the harmonization of the airport infrastructure with ICAO Annex 14 was not requested by the Ministry and was not analyzed by airport operators. Consequently, the implementation of standards and recommendations of ICAO Annex 14 was not done. Cluj, Romania, Sept /60

9 The airport certification process in Croatia based on ICAO Doc From February 2005 until March 2009: 3 airport operators received permanent Airport Certificate and 1 airport operator received interim Airport Certificate. From March 2009 until September 2014: 5 airport operators received permanent Airport Certificate. In the meantime, in May 2010, the first version of Ordinance on aerodromes (based on ICAO Annex 14) was published and that was the first detailed legal basis for provision of (detailed) analysis of compliance of airport infrastructure with standards and recommendations of ICAO Annex 14. Cluj, Romania, Sept /60

10 The airport certification process in Croatia based on ICAO Doc Ordinance on aerodromes is the copy of the final (actual) version of ICAO Annex 14, interpreted in Croatian language. Its essential feature is that all the ICAO Annex 14 recommendations are defined as standards. In Article 1, paragraph 6 of the Ordinance, is defined that its provisions do not apply to the airport existing infrastructure, if the (air transport) safety is not compromised. From October 2010 until May 2014, CCAA analyzed the harmonization of airport existing infrastructure with Ordinance on Aerodromes for 7 international airports and for all incompatibilities defined in those studies for each airport: made a risk assessment, and recommended mitigation measures. Cluj, Romania, Sept /60

11 The airport certification process in Croatia based on ICAO Doc Based on Article 14 of Ordinance on Airport Certification and Studies of existing aerodromes infrastructure harmonization with provisions of Ordinance on Aerodromes, from January 2011 until January 2012 all Airport Certificates (issued to Croatian airport operators) were changed by addition of new data: Aerodrome Reference code and Airport infrastructure incompatibilities. It can be concluded that the process of harmonization of the airport infrastructure with provisions of the Ordinance on aerodromes started in October Total number of non-conformities defined for Zagreb Airport was 127. Until today, 126 were closed. Cluj, Romania, Sept /60

52 Zagreb Inernational Airport EC Regulation 139/2014 What is the purpose of shoulders of TWY: Zagreb International Airport CERTIFICATION BASIS / TWY F SHOULDERS - ELOS for TWY F to prevent erosion of soil along the edge of pavement structure of the TWY, to prevent additional damage of the airframe of aircraft because of insufficient bearing strength of the soil along the edge of pavement structure of the TWY if the aircraft bounces off the TWY (rush out). to prevent suction of foreign object debris into aircraft engines. Cluj, Romania Sept /60

53 Zagreb Inernational Airport EC Regulation 139/2014 Zagreb International Airport CERTIFICATION BASIS / TWY F SHOULDERS - ELOS for TWY F In order to prevent: erosion of soil and suction of FOD into engine of aircraft along the edge of the pavement structure of the TWY, aircraft engines should not be above the soil while taxiing. additional damage of the aircraft airframe if the aircraft bounces off the TWY, the bearing strength of the soil has to be sufficient (CBR /ICAO Doc 9157 ADM, Part 1 RWY, Chapter , Third Edition 2006).

55 Zagreb Inernational Airport EC Regulation 139/2014 Zagreb International Airport CERTIFICATION BASIS / TWY F SHOULDERS - ELOS for TWY F Therefore: while the shoulders of taxiways A and E are not built, taxiing of (four-engined) aircrafts (code-letter E ) will be prohibited with active engines 1 and 4 taxiing of (four-engined) aircraft (code-letter E ) on TWY F will be prohibited with active engines 1 and 4, permanently. Cluj, Romania, Sept /60

56 Zagreb Inernational Airport EC Regulation 139/2014 Regarding the bearing capacity of the soil: Zagreb International Airport CERTIFICATION BASIS / TWY F SHOULDERS - ELOS for TWY F Based on laboratory tests provided in December 2013 by Faculty of Civil Engineering and IGH Institut (University of Zagreb), the soil bearing capacity defined as the California Bearing Ratio (CBR) is as follows: for a gravel foundation of soil, obtained values of the California Bearing Ratio (CBR) are approximate to recommended values ( CBR / ICAO Doc Aerodrome Design Manual, Part 1 Runways, Chapter , Third Edition 2006) For a gravel-clay foundation of soil, obtained values of the California Bearing Ratio (CBR) are higher than recommended values ( CBR / ICAO Doc Aerodrome Design Manual, Part 1 Runways, Chapter , Third Edition 2006) Cluj, Romania, Sept /60

57 Zagreb Inernational Airport EC Regulation 139/2014 Zagreb International Airport CERTIFICATION BASIS / TWY F SHOULDERS - ELOS for TWY F So, in terms of lack of taxiway shoulders, it can be concluded that there is no risk of: soil erosion along the edge of TWY pavement construction, or suction of FOD into aircraft engines because: the engines 1 & 2 (twin-engined a/c), or 1 & 3 (three-engined a/c), or 2 & 3 (four-engined a/c) are above pavement of TWY, and taxiing of four-engined a/c is prohibited with active engines 1 & 4. additional damage of the aircraft airframe because the bearing strength of soil is: approximate to recommended value of CBR (15-20), or higher than recommended value of CBR (15-20).
