Question to the Ministry of Defence:

To ask the Secretary of State for Defence, how Enhance Collision Avoidance System fitted in Typhoon aircraft interacts with Traffic Alert and Collision Avoidance System II equipped in civil aircraft in a potential collision environment.

Existing transponders fitted to Typhoon aircraft already have the capability to generate a traffic alert in any Traffic Collision Avoidance System (TCAS)-equipped civil or military aircraft.

It will reduce the risk of mid-air collision and enhance the situational awareness of Typhoon aircrew when in congested airspace, providing additional protection for our RAF Typhoon pilots.

Stage one of the Typhoon Enhanced Collision Awareness System will not interact with the civil TCAS.
