7 Determination for voice deactivation of Class C Control Zones
(1)Subject to this section, I determine that a volume of airspace described in Schedule 5 as a Class C Control Zone, temporarily ceases to be a Class C Control Zone and becomes airspace of another specified class if:
(a) the details for the Control Zone set out in Schedule 5 provide for its activation in accordance with an hours of activity statement that is a NOTAM (an activating NOTAM); and
(b) the activating NOTAM specifies a finish time for the activation (the specified finish time); and
(c) the Controlling Authority for the Control Zone uses voice telecommunication to a receiving ATC authority to deactivate the Control Zone earlier than the specified finish time (early deactivation) in accordance with subsection (2).
Note Activation times specified in a NOTAM are in UTC unless otherwise indicated.
(2)Early deactivation may only be carried out if the activity for which the activating NOTAM was published has been completed or otherwise terminated.
(3)Early deactivation may not occur earlier than 60 minutes before the specified finish time unless an amending NOTAM is issued.
(4)To avoid doubt, the period of activation of a Control Zone activated by NOTAM may not be extended by voice telecommunication past the specified finish time.
Note 1 For an early deactivation within the 60 minutes before the specified finish time, an amending NOTAM is NOT required.
Note 2 For an early deactivation that is earlier than 60 minutes before the specified finish time, an amending NOTAM IS required.
Note 3 For an extension to the specified finish time, an amending NOTAM IS required.
Note 4 A pro forma for an activating NOTAM follows:
