In the simulation, TCAS orders one plane to climb and the other to descend. TCAS steers the aircraft away from each other. “ clear of traffic” and re-engaging the autopilot, and two bubbles in which the aircraft is sitting moves to safe distance apart. Technology seems to finally (13) that pilots are not able to see each other. As a direct result of LA collision, TCAS is now (14) on all commercial aircraft flying to most destinations.
