When an operator receives the TCO authorisation from EASA, the authorisation is accompanied by technical specifications. These will contain the scope of the operations authorised in the EU, e.g. LVO, EDTO, PBN, DG. EASA will only authorise an operator for special operations (such as LVO) when the operator is certified for this operation by its competent aviation authority. In other words, the scope of the TCO authorisation can never exceed the scope of operations approved in the underlying AOC (Operations Specifications) issued by the competent authority of the operator.
