AMC1 SERA.6001 Classification of airspaces - ED Decision 2013/013/R
GENERAL
Where ATS airspaces adjoin vertically, i.e. one above the other, flights at a common level should comply with the requirements of, and be given services applicable to, the less restrictive class of airspace.
GM1 SERA.6001 Classification of airspaces - ED Decision 2013/013/R
GENERAL
- Class B airspace is considered less restrictive than Class A airspace; Class C airspace less restrictive than Class B airspace, etc.
- The speed limitation of 250 kt for VFR flights in airspace Classes C, D, E, F, G and for IFR flights in airspace Classes D, E, F, G is intended to facilitate visual acquisition of flights which are not separated.
- Wherever there is a need to accommodate within a given airspace class operations compatible with a less restrictive class, the following may be used:
- reclassification of the airspace concerned;
- redesigning the volume of airspace concerned by defining airspace restrictions or reservations, or subvolumes of less restrictive classes of airspace (e.g. corridors).
AMC1 SERA.6001(a)(4);(5);(6);(7) Classification of airspaces - ED Decision 2013/013/R
SPEED LIMITATION — SAFETY ASSESSMENT AND APPROVAL BY THE COMPETENT AUTHORITY
Approval by the competent authority of an alleviation of the 250 kt speed limitation below 3 050 m (10 000 ft) should be based on a safety assessment. The conditions for granting such alleviation should be specified in the Member State Aeronautical Information Publication (AIP).
GM1 SERA.6001(a)(4);(5);(6);(7) Classification of airspaces - ED Decision 2013/013/R
SPEED LIMITATION — SAFETY ASSESSMENT AND APPROVAL BY THE COMPETENT AUTHORITY
- The following should, as a minimum, be considered when developing the safety assessment:
- air traffic, airspace classes requirements, and airspace design, the procedures designed for the airspace, and the potential use of clearances to maintain own separation as described in GM1 to SERA.8005(b);
- the minimum safe speed stated in the approved Aircraft Flight Manual (AFM) of the relevant aircraft types.
- The safety assessment should be developed in coordination with the relevant airspace users.
- Coordination should be ensured with the affected airspace users who should provide the data necessary for the development of the safety assessment.
- The competent authority should ensure that the aircraft types eligible for such alleviation are specified in the Member State Aeronautical Information Publication.
GM2 SERA.6001(a)(4);(5);(6);(7) Classification of airspaces - ED Decision 2013/013/R
SPEED LIMITATION — SAFETY ASSESSMENT AND APPROVAL BY THE COMPETENT AUTHORITY
- For localised alleviations from the speed limitation, the safety assessment is normally conducted by the ATS provider and is subject to approval by the competent authority.
- Where alleviation is applied universally across the airspace of the Member State, the competent authority should ensure that appropriate safety assessment has been conducted.
AMC1 SERA.6001(a)(8) Classification of airspaces - ED Decision 2013/013/R
GENERAL
Class F airspace should only be implemented where the air traffic services are inadequate for the provision of air traffic control, and the limited advice on collision hazards otherwise provided by flight information service will not be adequate. Where air traffic advisory service is implemented, this should be considered as a temporary measure only until such time as it can be replaced by air traffic control service or, in cases where the traffic situation changes such that advisory service is no longer required, replaced by flight information service.
GM1 SERA.6001(a)(8) Classification of airspaces - ED Decision 2013/013/R
DURATION OF TEMPORARY MEASURE
- When establishing Class F airspace, its intended temporary duration after which it should be replaced by an alternative classification should be specified in the AIP of the Member State.
- The intended temporary duration of Class F airspace should not be longer than 3 years.
EXAMPLE
- Certain CTR airspace may change its classification on a daily basis (e.g. from 06:00 to 20:00 the airspace is classified as Class A, and from 20:00 until 23:59 and from 00:00 until 05:59 is classified as Class F). In this case, the duration of these arrangements should not exceed 3 years.

Mise en œuvre
- La limitation de la vitesse air indiquée (IAS) à 250 kt en dessous de 3050 mètres
(10 000 pieds) AMSL ne s’applique pas aux aéronefs de la défense qui, pour des
raisons techniques ou liées à la sécurité, ne peuvent maintenir cette vitesse.
- Des opérations aériennes effectuées en dérogation à la limitation de la vitesse air
indiquée (IAS) à 250 noeuds en dessous de 3050 mètres (10 000 pieds) AMSL pour des
missions de travail aérien ou pour des vols acrobatiques sont possibles après
approbation du directeur interrégional de la sécurité de l’aviation civile
territorialement compétent lorsque les aéronefs utilisés ne peuvent, pour des raisons
techniques ou de qualité de vol, maintenir cette vitesse.
Les opérations concernées ne peuvent se dérouler qu’à l’intérieur d’un espace aérien
permettant une ségrégation avec les autres usagers de l’espace aérien ou sur une
localisation d’activité de voltige publiée.
Cette approbation est fondée sur une étude de sécurité. Celle-ci est réalisée par
l’exploitant de l’aéronef et, lorsque les opérations se déroulent à l’intérieur d’un
espace aérien contrôlé, en coordination avec l’organisme de contrôle concerné.
