IR Implementing rule

## ADR.AR.C.025 Special conditions

(a) The [Competent Authority](https://avioverse.aero/glossary/easa/competent-authority) shall prescribe special detailed technical specifications, named special conditions, for an [aerodrome](https://avioverse.aero/glossary/easa/aerodrome), if the related [certification specifications](https://avioverse.aero/glossary/easa/certification-specifications) issued by the Agency referred to in point ADR.AR.C.020(a) are inadequate or inappropriate, to ensure compliance with the essential requirements of Annex Va to Regulation (EC) No 216/2008, because:

(1) the certification specifications cannot be met due to physical, topographical or similar limitations related to the location of the aerodrome;

(2) the aerodrome has novel or unusual design features; or

(3) experience from the operation of that aerodrome or other aerodromes having similar design features has shown that safety may be endangered.

(b) The special conditions shall contain such technical specifications, including limitations or procedures to be complied with, as the Competent Authority finds necessary to ensure compliance with the essential requirements set out in Annex Va to Regulation (EC) No 216/2008.
