as described in a classification Schedule ceases to be airspace of that class and becomes airspace of another specified class:
(a)              outside the hours of activity specified in the AIP or a NOTAM, that I have authorised in writing; or
(b)              if the ATC service for the volume of airspace has been suspended or has ceased functioning, in accordance with a NOTAM that I have authorised in writing.
       (3) A volume of airspace to which subsection (2) applies does not become airspace of another specified class if, at the time it would otherwise become such airspace:
(a)              AA continues temporarily to control the airspace under its initial classification (an extension of time); and
(b)              such control is necessary for aircraft separation or other operational reasons.
       (4) For subsection (3), the volume of airspace becomes airspace of another specified class when the extension of time ends.
       (5) The determination in subsection (1) ceases to have effect only if this instrument is:
(a)              repealed; or
(b)              amended, and then only in accordance with the amendment.

7 Emergency determination that airspace of a class becomes airspace of another class
       (1) I determine that a volume of airspace, described in Schedule 3, 4, 5, 6, 7, 8 or 9 (a classification Schedule) as being of the class mentioned for it in the Table in subsection 5(1) (initial classification), temporarily ceases to be airspace of that class and becomes airspace of another specified class in accordance with the condition mentioned in subsection (2).
       (2) A volume of airspace with an initial classification as described in a classification Schedule ceases to be airspace of that class and temporarily becomes airspace of another specified class (the new class) if hours of activity for the new class are specified in a NOTAM that is authorised in writing by me.
       (3) An authorisation may only be given on the grounds that emergency or other conditions affecting, or that are likely to affect, the relevant airspace make the temporary reclassification of that airspace necessary or prudent in the interests of aviation safety.
       (4) An authorisation mentioned in subsections (2) and (3) must include my determination that the grounds mentioned in subsection (3) exist.
       (5) An authorisation mentioned in subsections (2) and (3) may not remain in force for longer than 7 days but may be renewed in accordance with this section.
       (6) The determination in subsection (1) ceases to have effect only if this instrument is:
(a)              repealed; or
(b)              amended, and then only in accordance with the amendment.
