Airport master plans
4.11
Currently over 30 airports across the UK have adopted master plans. They do not have a statutory basis, but the primary objective of master plans is
to provide a clear statement of intent on the part of an airport operator to enable future development of the airport to be given due consideration in
local planning processes. They also provide transparency and aid long-term planning for other businesses.
