Introduction of controlled airspace in the region of the Portsmouth Danger Areas

Consultation: 30th June 2017 – 25th August 2017.

NATS is proposing to introduce a volume of Class C Controlled Airspace from FL125 to FL195 directly underneath the Southern CTA. The adjacent Portsmouth CTA (to the west) FL125+ will be reclassified from Class A to Class C. The Military will retain primacy over the airspace which contains three Military Danger Areas. This will deliver a uniform airspace classification of Class C across both airspace volumes and a uniform base of FL125.
