Airspace Safety: Restricted Area (Temporary) or RA(T)

Any airspace infringement brings with it a risk of airborne conflict. This risk may be higher within a RA(T) due to the nature of operations and limited barriers available to mitigate airborne conflict.

In 2024 there were 10 RA(T) infringements; to the end July 2025 the number has already reached 15. 

To prevent Airspace Infringements of a RA(T), pilots are encouraged to carry out detailed pre-flight planning to include:

• NOTAM briefing using the NATS Internet Briefing System at NATS Aeronautical Information Service (AIS) Website 
• Reference to the AIC or Briefing Sheet referred to in the NOTAM at NATS AIS 
• Call the NATS AIS Information Line prior to flight on 08085-354802 or +44(0)1489-887515. 
• Use a VFR Moving Map and apply the Take 2 guidance.
