Within the Lisboa FIR the airspace is classified “C”, “D” and “G”.
The airspace classification “D” has been allocated to the restricted areas LPR26A, LPR70A, LPR70BNLPR60B, LPR40A, LPR40BN, LPR40BS, LPR69A, LPR69BW, LPR69BE, LPR69BSLPR42B, LPR51A, LPR51BN and LPR51BS, while these airspaces volumes are affected to military use; when the air traffic service provided is delegated to civilian units, the airspace classification volume will change to “C”.
Within Santa Maria Oceanic FIR the airspace is classified “A”, “C” and “G”.
The airspace classifications “A”, “C”, “D” and “G” have been selected from the ICAO annex 11, as transposed in Commission Implementing Regulation (EU) NR 923/2012, of 26 September, SERA.6001 - Classification of airspaces and are described in subsequent paragraphs.
