Commentary on provisions of the Act Range control Section 5: Range
Subsection (1) of this section defines the term "range" in relation to spaceflight activities. This is a zone, consisting of a volume of airspace or an area of land or sea, where warnings, restrictions or exclusions are put in place at particular times to secure the area from anything that might pose a hazard to spaceflight activities, or to which those activities might be a hazard. A range may cover a very large distance, over which a range control service provider does not have direct control or power to exclude uninvolved parties. Segments of a range will be activated from time to time. This activation will not rely exclusively on matters provided for in the Act, but will involve an interface with other legislation and international procedures.
	Subsection (2) enables regulations to be made concerning the range or ranges for spaceflight activities. Such regulations may include, but are not limited to: matters to be taken into account in identifying the appropriate range; requirements on persons for the operation of the range; and requirements on the person providing the range control services concerning notification of others.
	Subsection (3) states that the power of the Secretary of State provided in the Transport Act 2000 to give directions to the Civil Aviation Authority (CAA) concerning air navigation includes a power for the Secretary of State to give the CAA directions concerning range for spaceflight activities. Section 66, subsection (1) of the Transport Act 2000 states: "The Secretary of State may give directions to the CAA imposing duties or conferring powers (or both) on it with regard to air navigation in a managed area".
