G.1 Development is permitted by Class G subject to the condition that, on or before the expiry of the period of 6 months beginning with the date on which the use began, the use shall cease, and any structure shall be removed, and the land shall be restored to its condition before the development took place, or to any other condition as may be agreed in writing between the local planning authority and the developer.
H. The use of land by or on behalf of the Civil Aviation Authority for the stationing and operation of apparatus in connection with the carrying out of surveys or investigations.
H.1 Development is permitted by Class H subject to the condition that on or before the expiry of the period of 6 months beginning with the date on which the use began, the use shall cease, and any apparatus shall be removed, and the land shall be restored to its condition before the development took place, or to any other condition as may be agreed in writing between the local planning authority and the developer.
