The baseline power limit, designed to protect the spectrum of other operators, and the transitional region power limits, enabling filter roll-off from the in-block to the baseline power limit represent out-of-block elements.

‘De-icing or anti-icing information’ means indication if de-icing or anti-icing operations occurred and if yes, where (before leaving the departure stand or in a remote position after departing the stand, i.e. after off block);

It consists of in-block and out-of-block components which specify the permitted emission levels over frequencies inside and outside the licensed block of spectrum, respectively.

They cover both emissions within the block of spectrum (i.e. in-block power) as well as emissions outside the block (i.e. out-of-block emission).

Where, due to circumstances that were unforeseeable at the beginning of the period and are at the same time insurmountable and outside the control of the Member States and the entities subject to the performance targets, alert threshold(s) referred to in Article 9(3) is/are reached at national or functional airspace block level, the national supervisory authority or body concerned shall review the situation liaising with the Commission and may provide proposals for appropriate measures within three months, which may include the revision of the national or functional airspace block performance targets.
