Did EASA Aerodrome rules come into force?

On February 14th 2014 Commission Regulation (EU) No 139/2014 laying down requirements and administrative procedures related to aerodromes pursuant to Regulation (EC) No 216/2008 of the European Parliament and of the Council was published in the Official Journal of the European Union.

Which regulations are applicable on UAS when operated in Croatia?

a) Ordinance on Unmanned Aircraft Systems “Official Gazette”, number 49/15 and 77/15

b) Ordinance on the rules of the air “Official Gazette”, number 128/14

c) Standardized European Rules of the Air (EU) No 923/2012

d) Air traffic act “Official Gazette”, number 69/09, 84/11, 54/13, 127/13 and 92/14

Which aerodromes fall within the scope of EASA?

Aerodromes fall within the scope of EASA if they meet the following requirements:

  • Open to public use and which serve commercial air transport and where operations using instrument approach or departure procedures are provided, and have a paved runway of 800 metres or above; or
  • exclusively serve helicopters.

What is the transition period?

The transition period called “conversion” is until 31st of December 2017.

What are the Acceptable Means of Compliance (AMC)?

The Acceptable Means of Compliance (AMC) are non-binding standards adopted by the EASA to illustrate means to establish compliance with Regulation (EC) 216/2008 and Regulation (EC) 1108/2009 (Basic Rule) and its Implementing Rules.

What are the Alternative Means of Compliance (AltMoC)?

The Alternative Means of Compliance (AltMoC) are those that propose an alternative to an existing Acceptable Means of Compliance or those that propose new means to establish compliance with Regulation (EC) 216/2008 and Regulation (EC) 1108/2009 (Basic Rule) and its Implementing Rules for which no associated Acceptable Means of Compliance have been adopted by EASA.

What is the Guidance material?

The Guidance material is non-binding explanatory and interpretation material on how to achieve the requirements.

What are the Certification Specifications (CS)?

The Certification Specifications (CS) are technical standards adopted by EASA indicating means to show compliance with the essential requirements of Annex Va and, if applicable, Annex Vb to Regulation (EC) No 216/2008 and Regulation (EC) No 1108/2009 (Basic Rule).

What is meant with Certification Basis (CB)?

Awarding of an aerodrome certificate is a two stage process. The first stage is to establish the Certification Base (CB) related to aerodrome's movement area according to EU regulation and uniqueness of the aerodrome, using:

the applicable Certification Specifications (CSs),
any proposed Equivalent Level of Safety (ELOS) by the applicant,
any special conditions (SCs) determined and notified by the CCAA.

Once the first stage is finalised, the second stage involves Aerodrome Inspections to assess the aerodrome's movement area compatibility with the requirements defined in CB.

Important note: Based on the new EU Regulation, the compliance of aerodrome’s infrastructure with relevant legal provisions is the basic condition which has to be fulfilled in order to issue the (new) Aerodrome Certificate (related to aerodrome’s infrastructure).

In other words, the CCAA will issue the certificate(s) when the applicant has shown that the aerodrome's infrastructure complies with the defined CB.

What is the Equivalent Level of Safety (ELOS)?

The Equivalent Level of Safety (ELOS) is the solution proposed by the aerodrome operator that must be explained and appropriately documented in order to comply with legal provisions. To become an integral part of the Certification Basis ELOS must be approved by CCAA.

What are the Special conditions (SC)?

The Special conditions are non-binding special detailed technical specifications determined by CCAA if the CS established by the EASA are not adequate or are inappropriate to ensure conformity of the aerodrome with the essential requirements of Annex Va to the Basic Regulation.Such inadequacy or inappropriateness may be due to the design features of the aerodrome or where experience in the operation has shown that safety may be compromised.

What is the Deviation Acceptance & Action Document (DAAD)?

The Deviation Acceptance & Action Document (DAAD) has been developed to support the acceptance process only. It is not intended for the DAAD to be used in any other circumstances. It should be produced jointly by the CCAA and the Aerodrome to document those existing deviations and non-compliances that remain after reviewing them with the new aerodrome rules. Remaining deviations and non-compliances included in the DAAD should be accompanied with:

  • A risk assessment analysis;
  • An action plan that indicates the conditions appropriate to removing them and/or any possible mitigation measures while they remain on the list and
  • An assessment of the degree of compliance with the measures implemented by appropriate legal provisions of CS.


It is intended that the DAAD will be individual to each Aerodrome, but may also contain state-wide elements as deemed appropriate by the CCAA.

What is Derogation Request?

If an existing aerodrome deviation from design CS could not be justified by using an ELoS or SC, the Member State would only have the remaining solution to send a derogation request to the European Commission.
