DETERMINATION OF AIRCRAFT TYPES AND VARIANTS

(a)When determining similarity of location and type of portable safety and emergency equipment, the following factors should be assessed:

(1)all portable safety and emergency equipment is stowed in the same, or in exceptional circumstances, in substantially the same location;

(2)all portable safety and emergency equipment requires the same method of operation;

(3)portable safety and emergency equipment includes:

(i)fire-fighting equipment;

(ii)protective breathing equipment (PBE);

(iv)crew life-jackets;

(v)torches;

(vi)megaphones;

(vii)first-aid equipment;

(viii)survival and signalling equipment; and

(1)land and water evacuation;

(2)in-flight fire;

(3)non-pressurisation, slow and sudden decompression; and

(4)pilot incapacitation.

(c)When determining similarity of doors/exits in the absence of operational suitability data established in accordance with Commission Regulation (EU) No 748/2012 for the relevant aircraft type(s) or variant(s), the following factors should be assessed, except for self-help exits, such as type III and type IV exits, that need not be included in the assessment:

(1)door/exit arming and disarming;

(2)direction of movement of the operating handle;

(3)direction of door/exit opening;

(4)power assist mechanisms; and

(5)assisting evacuation means.

SAFETY BRIEFING FOR CABIN CREW When changing aircraft type or variant during a series of flight sectors, the cabin crew safety briefing should include a representative sample of type-specific normal and emergency procedures and safety and emergency equipment applicable to the actual aircraft to be operated for the immediately subsequent flight sector.
