Responding to traffic information
“Looking”Traffic has been passed but you haven't spotted it yet — you're searching.
“Traffic in sight”You can see the traffic that was called.
“Negative contact”You've looked but cannot see the called traffic.
“Clear of traffic”Passed by ATC once you're clear, often with a turn — e.g. “clear of traffic, turn left heading 340”; acknowledge with Wilco.
Acknowledge a traffic call promptly with your sighting status. Under a Traffic Service you still take your own avoiding action.
