CAP 1781 is the CAA Guidance for the Use of RNAV Substitution and has been produced in support of a programme of airspace modernisation in the UK. NATS has embarked on proposals for significant airspace changes in Scotland, the North of England and the South-East of England, and aerodromes are developing complementary plans providing connectivity with the Network.

Ahead of airports introducing permanent airspace changes utilising PBN, CAP 1781 details a method of mitigation for continued use of conventional instrument flight procedures, in lieu of radiating navigation facilities as well as suggestions of other mitigating actions.

This document provides some additional guidance in response to questions received about CAP1781
