It's tough to judge without seeing a mode c altitude readout, they could have been separated by 1000ft+ vertically. TCAS RA's can trigger before minimum sep is lost. Also if they are both flying the RNAV DOCKR departure then their track should be the same and AAL wouldn't have been able to cut off ACA. In that case a speed restriction should be enough to prevent an overtake. Departure controller should have recognized it for sure, but someone wasn't flying the procedure.

The relieving controller expected ACA to be leaving 5,000 before they would be an issue with American.

You're probably right, but where did both get their clearances to 5000'? DOTTS2 is initial climb 17000' with DOCKR AoB 3000', WEILR AoB 5000' and DOTTS MNM 15000'. ORCKA5 on the other hand is initial climb FL230 also with DOCKR AoB 3000' and KLIPR MNM 10000'. I don't hear any instruction to climb 5000' only for either of the flights. Did KUSA give them that?

[@noytheya]

The controller forgot to climb Air Canada. Had AC been cleared to 12000 you wouldn’t be watching this. Instead, AC leveled at 5000, which is what AA was cleared to, causing the close call. Had AC been given the climb to 12000 on initial contact, as soon as they crossed American would have got the climb to 12000 too. Done correctly, this is a typical operation.

OK. I am probably missing something here. Both aircraft where given RNAV to DOCKR and both cleared to climb 5000. After the transfer, Departure is keeping the clearance unchanged and restricts speed for AAL.

But we see that AAL is not following the same track the ACA was on before the 110 heading.

[@johnaclark1]

Both airplanes went to DOCKR as cleared. Their cleared routes diverge after that as they were on different departure procedures that both use DOCKR as the first RNAV fix but diverge after DOCKR. This was controller error, not pilot error.

I don’t like that the Orcka and Oshnn departures both share the same initial fix too. (Dockr or Hiipr depending on the runway)

[@phillp7777]

what's RA ?

[@kacey8372]

TCAS resolution advisory. Equipment on the planes communicated with each other so that one plane was ordered to descend and the other to ascend regardless of any possible ATC mistake. They advised ATC that they received and followed that resolution advisory because that's the case when pilots are allowed to ignore ATC and listen to the plane

[@CMDRFandragon]

Where was AAL going? Seems like they shoulda been following right behind ACA.

[@truckinfool3550]

Possible controller deviation, advise when ready to copy a number…

[@artgreen6915]

Any departure effectively 'cutting the corner' on a bigger turn the previous departure is making will create a risk. Why don't they just say begin your turn at 2 miles out? If everyone begins their turns at roughly the same point this can't happen.

[@adamsmeltzer9959]

[@WingsOfDay]

Why was the exclamation point added about turning immediately, the controller was calm with no change in his voice.

[@daemn42]

At first blush this looks like mostly an ATC issue, but both planes were supposed to be on RNAV to DOCKR departure which means they should have been on exactly the same track maintaining fixed horizontal separation. Either ACA782 turned left too late past DOCKR (or not to heading 220) or AAL345 turned left too early. To my eye it looks like AAL345 turned to 220 exactly where they were supposed to, while ACA782 was on like 230-235 and late. Had they been on same track in front of AAL345 there would have been no issue when ATC turned them to 110. It seemed odd that AAL345 tried to turn left inside ACA782 but I think again they were on the proper DOCKR - SHAEF track with a turn at SHAEF to 155, and with visual contact thought they could just fly underneath em until ATC got involved and made a mess of it.

[@michmart9261]

I wonder why everybody gets the same initial altitudes, when on similar departures..

[@johnaclark1]

Most likely to stay below arrivals in case of radio failure.

[@SheAirFire]

My only question...But why, ATC?

[@davidwallace5738]

What does RA mean as said by the AC pilot.

[@economicprisoner]

Resolution Advisory in the Traffic collision avoidance system (TCAS)

[@cheapspeed]

It's the final warning of immediate danger of a midair collision

[@Rennyteam359]

I would expect LAX will be reviewing this and take the necessary moves to see it does not happen again. Both pilots did exactly as directed. What we do not know is what the situation was in the IFR room,(TRACON), at that moment. Controllers have to learn to think quick as a bunny and make instant decisions based on the situation at tha moment. Now retired from moving Iron Birds, even with the new technology the job hasn't gotten any easier. It has gotten worse. Not eveyone is cut out for this job, especially at this level of a facility. Alway remember you can call or visit the facility to get explanations of procedures.

[@TheWayOfJamesBand]

AAL345 was flying his route correctly, if you look at the chart. The two aircraft are on different departure routings, and both flew them correctly. The controller is solely responsible for turning ACA back into AAL without the necessary vertical separation.

[@YouveBeenMiddled]

@@Taladar2003 They got a new frequency at the end because this controller was removed from duty.

[@franck7779]

⁠​⁠@@TheWayOfJamesBandI think you’re wrong. Check again the initial climb of RNAV DOCKR on LAX SID pages. Whatever is your SID, you have to overfly DOCKR and then fly HDG 236, waiting for SoCal to clear you to another HDG or point. I took off from LAX to Paris yesterday, that’s how it works.

[@GK-sn1jx]

Great content, but you should include an overlay of the departing aircraft SIDs. This way we know turns done by either aircraft are part of the SID or pilots doing their own thing like the American possibly turning to a heading of 250 instead of increasing speed to 250. I understand a lot of SIDs are not to scale on charts though, so it may be a tall order.

[@mduralia]

Is it just me or were both aircraft not give the same departure to DOCKR? Did the American deviate? The ACA turning should not have affected the AA continuing "straight" until given a new heading?

[@tomlathrop4094]

why is this necessary? Why not just fly the SIDS in the flight plan?

[@robburgundy9539]

Its because the ORCKA5 out of LAX has Radar vector instructions. After departure.

[@williamlilliott2433]

What is an RA?

[@road_rider]

A Resolution advisory from TCAS. Basically the system thinks there is a good chance of a mid air collision and the system will tell the pilots to take immediate action to avoid that.

Thanks to the ATSAP program, that controller will not receive any remedial training and will continue to do a poor job the next day and likely throughout his career. There used to be severe consequences for rule violations, but not anymore.

[@alk672]

That is one weird way to have a traffic conflict. Someone in the tower is not paying attention.

Not his fault with the guy in the tower...it's the radar controller giving vectors and not alert enough to see what he did wrong

Literally "cutting corners".

[@Steven-zp8hf]

Does the TCAS issue commands independently of other aircraft's TCAS or does it work with their TCAS to avoid collision? I.e could both TCAS ever issue a command that results in both aircrafts coming together? Silly question but not a pilot here...

[@martynrich5187]

Its that headfing 110 and keeping them at the same altitude, he must not have seen the 2nd radar contact pr something given it was just taking off.

[@juli99475]

Why are they not flying the same departure? Both hat RNAV to DOCKR or did I miss something?

[@johnaclark1]

Two different SIDs that use the same initial fixes. ORCKA5 vs OSHNN1

[@Nicetrybrobro]

I got a number for the controller to write down...

[@as-guardianangel9360]

The AC looked to be on the ORCHA where as AA on the DOTSS… ORCHA is a vectored departure and DOTSS is a CVS. Not sure why ATC allowed the American to takeoff that close to the Aircanada. The point of the ORCHA departure is to vector the planes in a 180, then direct NE over LAX….tower should have known that….

[@NATHENEXPL0SI0N]

They were both on the same SID. why did American deviate from the SID before being given a heading? The controller has a lot of blame here but the American plane was deviating from the procedure prior to being given an instruction.

[@CharlieFoxtrot00]

They weren’t on the same SID. American was following theirs. Air Canada was also following theirs, which requires an addition ATC instruction, a vector to turn.

[@NATHENEXPL0SI0N]

@@CharlieFoxtrot00 I’m pretty sure they were cleared for take off on an identical SID. Listen again Edit: yes they were both in the RNAV DOKER SID … forgive doker misspelling if it is Edit 2: looks like they were both on the OSHNN 1 SID and DOCKR is the first way point

[@CharlieFoxtrot00]

@@NATHENEXPL0SI0N DOCKR is the takeoff clearance. Like “fly runway heading,” but LAX gives this to avoid confusion with runway 25L departures that go to HIIPR. Regardless, and to be clear, there are three departures that use DOCKR as the beginning waypoint: ORCKA, OSHNN, and DOTSS. There is no DOCKR SID. Air Canada filed ORCKA, AA filed DOTSS. Review the charts to see how this conflict became possible.

[@bd5289]

Departure controller told Air Canada to turn left...that started the whole mess!

[@SoloPilot6]

"RA" = "Resolution Advisory" -- the TCAS system telling the pilots to change (or not change) their altitude, QUICKLY, because of another plane in conflict. Pilots are trained to follow TCAS instructions, no matter what the controller is telling them. In other words, there's immediate and real danger of a mid-air collision, and the TCAS systems in each plane are talking with each other to keep it from happening. Why did the controller have 782 make a left turn in front of a following plane that was already turning?

[@flycow69]

The scope was clear of any arrivals from the departures side why even make departures complicated instead letting the pilots use LAX published departures that what pilots expect to use.

[@CharlieFoxtrot00]

The ORCKA departure that AC was on requires an ATC instruction to make the turn back to the NE toward KLIPR (which is just about back over the airport, just shy of the beach) or any subsequent waypoint. The DOTSS departure, which AA was on does not.

[@DaveDepilot-KFRG]

American please speed up to 250 so you can ride up to AC's tail. You were cleared for take off too soon so lets see if we can make the problem worse.

What’s an RA that Canada Air was referring to?

A resolution advisory. It's basically an alert from TCAS "traffic collision avoidance system" that tells you a collision is about to happen and gives you maneuvering instructions to avoid the collision.

[@prilep5]

Communication should have a backup text messaging system in place because of radio distortion and interruptions plus accent makes inefficient and unsafe navigation
