Airspace & Safety Initiative

The Airspace & Safety Initiative (ASI) is a joint CAA, NATS, AOA, GA and MoD effort to tackle major safety risks in UK airspace.

The project was formed following top-level discussions between the CAA Chairman, NATS Chief Executive and MoD Assistant Chief of the Air Staff that highlighted a a number of incidents where light aircraft infringed controlled airspace, or military and commercial flights lost separation outside controlled airspace.

It aims to help reduce incidents such as infringements of controlled airspace by providing free information to help encourage good practice for all pilots.
