From the Planning Statement
The Airport needs to develop its security search facilities in order that new
equipment that complies with modern standards can be installed. This will
improve the overall efficiency of the security search process and improve the
speed that passengers can be processed. This scheme does not increase the
overall capacity of the passenger terminal it provides an improvement to the
passenger experience.
