Part 1: Airspace change proposals Section 2: Direction to progress airspace change proposal
Section 2 enables the Secretary of State to give a direction to a person involved in airspace change, once they have been consulted, requiring them to prepare an ACP or take steps towards the preparation of an ACP, to submit an ACP to the CAA, to take steps to obtain the CAA’s approval to a proposal submitted to it, and/or to review the operation of an ACP that has been implemented following approval. A direction could be given to an airport operator, air navigation service provider, or any person with functions related to air navigation. A direction given may require the person to do specified things by specified dates and require the person to keep the CAA informed at specified intervals of the progress being made towards the direction being taken forward.
	A direction would only be able to be given by the Secretary of State if the Secretary of State considers that to do so would assist in the delivery of the CAA’s airspace strategy, which is prepared and maintained by the CAA (under directions given to the CAA under section 66 of the 2000 Act). Under the current Directions, (namely the Civil Aviation Authority (Air Navigation) Directions 2017, as amended), the CAA is required to "prepare and maintain a co-ordinated strategy and plan for the use of all UK airspace for air navigation up to 2040, including for the modernisation of the use of such airspace" (see direction 3(e) of those Directions).
