STS,The ANO which makes Clause 3 of the aerodrome licence demand that any changes to the aerodrome must be approved by the CAA before they can be done would suggest that approval has been given. Either that, or at the next CAA audit, it will have to be taken down. Considering it will be in close proximity to the inner horizontal surface, I should imagine the correct approval will have been made before commencment. Or do you mean the ones down the apron?An assumption here, but I think you mean TranSec not DFT! They dont care about landside/airside. They just want to see how you control access to either area!.What should be addressed at LBA is the proximty of the Fuel storage Installation to the runway. As far as Peel is concerned, they are just aquiring assets, loss making or otherwise, for business reasons. If I was Clinton working at Leeds, I would be more concerned about who the next CEO will be. I hear on the grapevine its a man called Den Perry!!
