P18 is a Conditional Route (CDR) with associated Airway, located between NATEB (Newcastle) and ADN (Aberdeen). Its current hours of availability (detailed withing the UK AIP) are limited and prevents the optimisation of environmentally efficient routings. As part of the Operational Service Enhancement Project, NATS has identified the need to increase the hours of availability of CDR P18. Increasing the hours of availability would enhance connectivity whilst improving fuel efficiency and reducing green-house gas emissions.
