Except where the context otherwise requires, nothing in this Act applying (in whatever terms) in relation to property (including any aerodrome) which is owned or managed or controlled by the Secretary of State or which he proposes to acquire shall apply in relation to such property unless, as the case may be, he owns, manages, controls or proposes to acquire the property in connection with the exercise of his functions relating to civil aviation.

Any reference in this Act to the carrying out of works on land shall be construed as including a reference to the making of excavations on the land or to the carrying out of levelling operations on the land; and references to the maintenance of works or to interference with works shall be construed accordingly.
