ICAO CIR 213 Pilot Skills to make “lookout” more effective in Visual Collision Avoidance
This circular aims to make pilots aware of the skills required to make "look out" more effective. These skills include the application of effective visual scanning, the ability to listen selectively to radio ransmissions from ground stations and other aircraft to create a mental picture of the traffic situation, and the development of habi patterns that can be described as "good airmanship".
