The Airspace Utilisation Section is responsible for processing, facilitating and promulgating the requirements for airspace in respect of special or unusual aerial activity (UAA). A UAA is any event such as an air exercise, trial, display, formation, balloon or kite flight which could adversely affect the normal operation of other airspace users.  In addition the section is also responsible for establishing emergency restriction to flying, restrictions of airspace (temporary) RA(T), and exemptions to enter restricted areas.
