If the Secretary of State is satisfied with respect to any local authority aerodrome that it is necessary or expedient that the local authority maintaining the aerodrome should be empowered to carry on in connection with the aerodrome any ancillary business which the authority would not otherwise have power to carry on, he may make an order authorising that local authority, subject to such conditions (if any) as may be specified in the order, to carry on that business in connection with the aerodrome.

In this section—

• “ancillary business” means any business which appears to the Secretary of State to be ancillary to the maintaining of an aerodrome; and

• “local authority aerodrome” means—

  1. a

     any aerodrome maintained by a local authority under section 30 above; or

  2. b

     so much of any other aerodrome as consists of buildings or other works maintained by a local authority by virtue of that section.
