In a report that will make you want to travel by car for the rest of your life, the FAA's records detail how "near collision" episodes are frequent and ongoing.
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.
For those that don’t speak plane, this is like saying every red light that tells you to stop and wait for someone is a near miss.
Pilot above is saying they got a red light 5 times in 15 years… hell, they got a give way 5 times when there was actually something there would be more accurate.
If you need an explanation, that means you don’t understand the issue well enough to be qualified to decide whether that explanation is good… It’s not and the article is not shitty journalism.
no i am not and no, the point definitely does not remain.
first, phrasing it like “they didn’t follow TCAS” make them sound like some reckless cowboys, which is simply not the case. they did exactly what they were told by tcas and when they got contradicting order from ATC the did exactly what they were told by him.
second, the statatement “was a result of the one crew not following the TCAS instruction” is simply not true. the accident was a result of ATC (as in the organization, not the specific people having the shift that night) fucked up". reading that linked wiki article may be good place to start to learn about the accident.
Had both aircraft followed those automated instructions, the collision would not have occurred.
That is right from the wiki.
I never claimed the pilots were “cowboys”, you made that up in your head. I simply said the accident was a result of not following TCAS, which at its core is correct. Of course there are multiple contributing factors, ATC being the largest, but my post was already getting long winded.
and had all the pilots overslept that day the incident might not have happen as well and in spite of that, we don’t list them getting out of the bed in the morning as a reason of the accident.
them obeying the atc command was reasonable and expected course of action.
them obeying the atc command was reasonable and expected course of action.
That’s incorrect, and is exactly why we train to ignore ATC commands and follow TCAS advisories. We don’t even tell ATC if we’re climbing or descending, simply “Aircraft XYZ, TCAS RA”

This article can fuck right off.

I see you don’t “speak plane” as well, because this is a terrible explanation
Obeying red light is like obeying air traffic. controller.
getting TCAS advisory is as if you had a system in your car that would tell you “you are too close to the car In front of you - slow down!”
He’s not explaining the system, he’s explaining why the article is shitty journalism, and it works fine as an explanation for me

Did your mum say it was good and pin it on the fridge 😂
That is serious misinterpretation. that crew followed their TCAS until they got conflicting instructions from the ATC…

I believe you are getting pedantic - when they got conflicting info they didn’t follow the TCAS. Point remains, they didn’t follow the TCAS.

And guess since when it is done that way…
According to the wiki…
Two years prior to the accident, in Europe, where the accident happened.
