Look at that crowded airspace, crazy how ATC can manage all that.

[@deans6129]

The American east coast is one of the most crowded airspaces in the world. At any given time at peak hours (6am to 10pm) on the US east coast approximately 3100 aircraft, helicopters, military and civilian general aviation aircraft will be airborne. In the entire US at peak hours approximately 5600 aircraft are airborne. (2023 FAA statistics) Compare that with eastern Canada (Ontario, Quebec, Maritime provinces) there are approximately 1600 aircraft, helicopters, military and civilian aircraft are airborne during peak hours.

[@DaveP-uv1ml]

All of those planes are required to have TCAS (collision avoidance system). It’s there as a last resort in case somebody screws up.

[@randal_gibbons]

AI is going to replace at least 90% of the controllers.

[@chrisstromberg6527]

It gets busy up there check out SFO OAK SJC or LAX ONT SNA or ORD MDW, for some other really crowded airspace. This is why I don’t get why ATL is always beating their chests with handling the most traffic. The enormous amount of traffic being handled in SoCal , NorCal, the North East just dwarfs what ATL is doing!

[@bks252]

Automation on the controllers side and the division of airspace.

[@user-wk8rc6ln7k]

Very damn high quality video, especially with all the extra info (locations, abbreviations, etc). I think this channel is underrated

[@AirTrafficVisualised]

Thank you very much, glad the extra effort doesn't go unnoticed.

[@lmamakos]

I like the visulaization of the map. In particular, it's helpful to see the waypoints identified. Thanks for all of the extra detail!

[@AllHailMerp-DBMusician]

Right when I get interested in ATC again I see this upload. Thanks for the vid, keep up the great work!

[@jcdock]

Amazing quality video. From start to end!

[@Michael_K_Woods]

The graphics are the best I have ever seen. You thought of every little detail. Fantastic.

[@GreatCdn59]

I agree! Some channels are focused on "fast upload" with limited info, lots of speculation and loads of typos in the subtitles... but I love that this channel takes more time to get all the details in! It's so fascinating to watch when stuff like this is done right!

[@AirTrafficVisualised]

Thank you both for the kind words! The support of viewers allows me to spend extra time making sure I get it out right rather than fast.

[@MazzieMay]

I wish I got into ATC before the cutoff age. Juggling all of that looks really engaging! Thanks for another top tier episode

[@Sihayanami]

Same here! It's endlessly fascinating. I've been looking into a career change, and I was disappointed to learn that I'd aged out of ATC training where I am too. I wonder how similar flight dispatch might be in terms of skillset?

[@DesmolightDesmo]

If you're very interested, there is something named VATSIM, its a simulator for aviation. Where real people can either fly an aircraft or be an air traffic controller. But the general principle is that everything is handled by an actual person. You should look into it! The training to become a controller is actually very in-depth and given by real world controllers and sometimes handled by them as well! Becoming a controller is actually free if you already have a computer that operates windows 10. Check it out! You can choose which airports you want to control and such.

[@Boodieman72]

I would think missing a slide would be a no-go item so a return or diviert would be necessary.

[@malahammer]

it was more than missing a slide. There was damage, vibrations and something banging against the fuselage.

[@edwardrichardson5567]

​​@@malahammer the slide

[@ir655]

If a slide is missing that means that door is inop for evac. They also have to block off certain amount of pax seat on the side of the affected door.

[@jakint0sh]

Absolutely spectacular quality, as always! Keep ‘em coming!

[@Sihayanami]

Your always excellent graphics have been getting more and more dynamic lately! Very cool. Your software must be coming along nicely 😃

[@teamofsteve]

Another excellent presentation. Love it

[@Tom-lu9gj]

Thank you!

[@stephanieparker1250]

Thanks for another great video, y’all do great work. I liked the follow-up photos of the damage and slide recovery.

[@ksbear2]

Loved the animation of the flights in the NYC area.. I found it interesting that EWR and LGA were landing on the 4s, rather than the 22's (opposite direction from JFK). Also, JFK was launching some flights on the 31 vs 13 as was being done at LGA. Amazing coordination between all three airports (and I wasn't even looking at the other airports in the area.)

[@user-yu5ry1js7w]

Was "Priority Handling" a typo for "landing"?

[@benbookworm]

Say it with me, "PANPAN! PANPAN! PANPAN! Delta 520" Based on various ATC recordings, pilots in the US seem reluctant to declare an emergency. And report fuel in time, not just weight! Time is useful to ATC, weight is useful to pilots and potentially ground crew like firefighters.

[@DaveP-uv1ml]

US pilots are taught that if that is an emergency, or if they feel that is an emergency, then they are not to hesitate and to declare it. That no penalty will come from doing so. And this is emphasized by both the corporate side and the government side the FAA. Yet some are just reluctant to do this for whatever reason. Perhaps the pilot just didn’t feel that it was an emergency?

[@Mikey109105]

Also notice how he said he had only 72.2 pounds of fuel? Thats basically running on fumes for a commercial jet. He definitely meant to say 72,000 probably though.

[@thewatcher1894]

I will say for the fuel, the controller asked for the fuel in pounds, not time after confirming that the plane just took off from Kennedy, so time remaining for fuel wasn't considered an issue since they were planning on being in the air for 6+ hours

[@Darthvader-oc5tp]

I mean, this wasn't really an emergency though. The aircraft was still controllable, they didn't lose an engine, and they didn't lose pressurization. It was just a precautionary landing because they didn't want to continue the flight and cause more risk that could lead to an actual emergency.

[@Darthvader-oc5tp]

@@Mikey109105 he did correct himself and said thousand pounds after he said 72.2 pounds

[@donaldgrump5393]

ATC: are you declaring emergency? Pilot: NOPE. ATC: but you have an issue and want to return to the airport ASAP? Pilot: YEP. ATC: give me souls on boards and fuel remaining. Also ATC, in their head: now say with me so you learn next time: PAN PAN, PAN PAN, PAN PAN

[@alexanderklimke6508]

It seems as if there was only emergency or not. If yes, it's handled like a mayday. Hardly anybody declares a pan pan.

[@guitargyro]

Jeeze, why the reluctance to declare an emergency? You have a slide banging against the side of the fuselage. Just declare.

[@felderup]

fuselage intact, nothing sucked into an engine, hasn't entangled the elevators or rudder, not an emergency.

[@benbookworm]

Make a confident PANPAN call, but US pilots seem to request to return and make ATC declare the emergency for them.

[@johnthompson6550]

Over 6 hours! Are you kidding? Use 2 fly it in 4hours 30 minutes still air. WTF

[@kevinm6510]

Just declare the emergency- always reluctance to do so.

[@therealxunil2]

The slide won't *incur* damage *to* the flaps etc. The flaps will incur the damage which the slide causes.

[@Yuracirlce]

Probably the same flight that they caught the handlers throwing those hockey bags.

[@austinfarley4971]

Does separated from the aircraft mean that some new yorker has a new inflatable slide?

[@TheRealScooterGuy]

Had you watched the whole thing, you would have seen the recovery photos of the slide. It ended up in the water.

[@rogerrogerorger]

Did you see how fast he took off? That was the issue

[@Mikey109105]

72.2 pounds? Uhhhh.....that's a fuel emergency there. I'm pretty sure he meant something more like 7.200, or maybe even 72,200, considering they were bound for LA, but yeah. Surprised no one caught that.

[@TheRealScooterGuy]

Listen again. He corrected it to add "thousand" at the end.

[@randal_gibbons]

I suspect that AI will be replacing at least 90% of the controllers in the near future.

[@moonlee9898]

No jettison? So that should be an overweight landing?

[@malahammer]

The crew and company deemed it OK.

[@ardeladimwit]

why? carrying less than half the fuel capacity of the plane.

[@cruisinguy6024]

I assume there was no need to jettison fuel as they were already at a safe landing weight. It’s only an overweight landing if…….its over the weight threshold for normal vs overweight. They weren’t even half full of fuel.

[@culdeus9559]

Was a heavy going ny to la probably was light enough on roll.
