With the number of manufacturers of remote tower equipment potentially increasing in number, how costly would it be to transfer from one manufacturer to another? Sensor and camera technology could be unique in design along with its interface with how the data is presented to the controller.
Any ATC service provider who was looking at taking LCY, would face a choice of embracing the current Saab equipment that is installed, which would be cheaper but could this pose a problem if the other service provider is perhaps accustomed with equipment from a different manufacturer?
Would the remote tower equipment at LCY belong to NATS or the airport? If it's the latter then could that perhaps add a further cost to any service provider that may ever look to knock NATS off their perch at LCY?
