To ask the Secretary of State for Defence, pursuant to the Answer of 19 November 2018 to Question 189831 on European Fighter Aircraft: Safety Measures, and with reference to Regulatory Article 1205 para 1b, on what basis the operating duty holder's tolerable and ALARP safety statement for the Typhoon aircraft is made when considering the mid-air collision risk.

The requirements of Regulatory Article (RA) 1205 para 1b are fully met as part of the Operating duty holder's Tolerable and ALARP safety statement consideration of mid-air collision risk.

The Typhoon Safety Case explicitly states what is Reasonably Practicable and Tolerable in terms of fitment of Collision Warning Systems and the other systems detailed in RA1205 for this platform. The RA states that the 'Collision Warning System' term is intentionally used to allow flexibility in identifying the optimal solution for platforms, including those currently under development.
