  • Let me add some context from the perspective of an airline pilot who is also is a company training captain.

    All modern transport category aircraft are equipped with a system called TCAS, or Terminal Collision Avoidance System.

    TCAS operates by interrogating the TCAS system of other aircraft in a defined proximity ring based on some variables like altitude and rate of closure and resolves a climb/descend/level command to each aircraft, which we pilots train regularly to execute. The system is a near perfect solution to deconfliction when collision is probable.

    With daily average flights in the US alone around 45 000, the amount of “near misses” is an incredibly small percentage. In 15 years of flying TCAS equipped aircraft, I’ve had 5 actual TCAS RAs (RA stands for resolution advisory - the actual avoidance maneuver)

    Another way to look at it is: when was the last mid-air collision in the US, or even the world involving TCAS equipped airliners? The only one that comes to mind is the DHL-BAL mid air in 2002, which was a result of the one crew not following the TCAS instruction.

    This article can fuck right off.
