May I ask you, in what sense do you mean simulations: operational simulations, operational scenario simulations?
If that's your question, sir, yes, we have done many, many simulations of operational scenarios for all three roles that we embark on: air defence; air-to-surface, sea and land; and reconnaissance. We do these and have done these in many regions and scenarios globally, worldwide. In fact, we have looked at the Arctic situation you face here in terms of our range and endurance, what we could expect to offer from the aircraft. Behind our statement that we could comply and meet your requirements, we have done simulations to ensure this is correct.
