The design, certification and approval of aerodromes shall be based, inter alia, on the aerodrome reference code (ARC) consisting of the following elements:
In particular, the infrastructural design of the movement areas (e.g. RWY/TWY width, load capacities, minimum distances, etc.) in accordance with the EASA guideline CS-ADR-DSN is based on the ARC. If aerodrome operators intend to operate aircraft with a higher code letter (HCLA) than indicated according to the certification basis, prior approval by the responsible approval authority according to EU/EASA ADR.OPS.B.090 Use of the aerodrome by higher code letter aircraft is required. The basis of this approval is the implementation of a compliance analysis and subsequent safety assessment in order to demonstrate that the existing aerodrome infrastructure as well as the organizational and operational structures permit the safe flight operation of HCLA (e.g. operation of code F aircraft on an aerodrome with ARC 4C).
The compliance checks carried out by GfL essentially comprise the following process steps:
Analysis of status quo:
For non-compliant combinations of test criteria and reference aircraft, assessment is first carried out to determine whether the HCLA procedures currently available at the respective aerodrome are sufficient to ensure safe flight operations. If these are assessed as inadequate, the following examination steps are carried out:
If infrastructure deviations are detected, risk mitigation measures, operating procedures or operational restrictions shall be implemented in order to achieve an adequate level of safety. The measures to be finalized may include, for example, the following:
Operational risk mitigation measures:
Infrastructural risk mitigation measures:
In the overall result, the compliance and risk analyses carried out in accordance with the above-mentioned methodology provide a comprehensive assessment of HCLA operations at aerodromes and form the basis for the preparation of corresponding application documents for submission to the competent authority.
