Thank you, Mr. Chair.
My question is about detection systems, and it's for Mr. Girard.
If I understand correctly, usually, when a foreign aircraft enters Canadian airspace, a flight plan has already been filed, so the appropriate authority is aware of the flight's arrival and can manage it accordingly. How do you handle an inbound foreign aircraft that has not filed a flight plan? What happens in that case? What is your role?
I have another question.
A detection system alerts you when an aircraft is entering Canadian airspace. Is NAV CANADA's detection system the one that the Department of National Defence uses? Does the Department of National Defence have its own system? How does it work on that front?
