§ Mr. Redmond
To ask the Secretary of State for Defence what is the capability of the identification friend or foe system in the Tornado F3 aircraft to receive the secondary surveillance radar codes of civil aircraft. 
§ Mr. Soames
The Tornado F3 is able to receive secondary surveillance codes of civil aircraft, provided it has been notified of the civil aircraft's code number. In common with other military aircraft and our allies, civil aircraft are located chiefly through use of the F3' s primary radar and visual identification. These techniques augment procedural separations enforced by air traffic authorities.
