I read somewhere that they’re now saying it was birds?

did they declare PANPAN or MAYDAY? Is it a delta thing or US aviation thing to avoid declaring an emergency and also to avoid saying PAN or MAYDAY kind of like on delta when they say to wear seat belts when the light is on because might experience “rough air” instead of “turbulence”

I was gonna say, he checked a few times to make sure he didn't leave anything behind. Very respectable and professional attitude.

I mean, it's their job.

Yep, don't want a repeat accident like the Concorde

Only briefly

@@mro-aviation On a fly by wire aircraft....

Right?!!

In a lightning strike its possible during excess energy dissipation process (ground becomes momentarily live as the lightening energy is dissipated through the body of the aircraft) that the FD and displays might cycle off and on to protect the electronics. Think of a mini trip switch that comes back on after a couple of seconds. Purpose is to protect the flight controls / instruments. As they say, its a designed feature :) Landing into lightning is prohibited and a divert for this reason.

Amen to that.

remember the Concord.....

She was controlling tower. She was offering the flight following but approach could have still deny it. She was asking for coordination purposes.

He was already off the ground going opposite directionbetter than sticking him in the pattern

A few inches of high speed tape and they'll be good to go.

NASCAR pit crew can have that back up in the air in about 30 seconds.

Storm: I see no reason we need to get the insurance companies involved.

@@apple54345 hahahaha

Peter G Plane: I would really just feel better if I got your information.

likely that nobody was recording the frequency/location when they declared.

@@RS-uo2nd Someone would need to be listening and recording the frequency, then send in the recordings.

C H LiveATC provides archives. This enables people who have used radio frequencies listed on their website to go back and save a clip from the past 30 days. This also means you don’t need to be listening to any given frequency live in order to record it, because they are already recorded. The reason you often don’t hear other aircraft is simply because not all transmissions from aircraft are picked up/recorded by the website.

Flying through a thunderstorm isn't very safe either. They only lost controls for a brief moment. After all, it is an advanced fly by wire aircraft.

Yes, they declared about 10 minutes earlier but I couldn't find audio

JFK is a major hub for Delta. They always keep extra equipment on standby for their planes. Source; I work at JFK.

They are based in the sunbelt, which has the second worst severe weather after Tornado Alley.

Leading edges and engines most likely. Something that'll do that much damage to the nose has the potential to damage fan blades and wings/tailfin as well.

@@aeternusdoleo4531 Not to bother mentioning that they lost all flight controls on a fly by wire aircraft.

Andy Taylor -I don’t think so.

David vE What does that mean to ‘briefly’ lose all flight controls? That must be a fbw distinctive issue. And how/why would that occur, then somehow be restored?

@@speedlever I'd guess radar shorted out, caused power surge, fuses blew, then flight controls rebooted.

The radome needs to be thin enough for the radar waves to go through the material

It sure hit the windows too

lol

Delta: Do Everything Like Total A-holes

Difficult to get it 100% spot on since not even native speakers can get things right sometimes.

WendyKS93 windshields are double paned near bulletproof glass. Radomes (nosecones) are fiberglass composite. The windshields are incredibly strong.

@@prorobo Yes they have greatly improved the windshields on the planes but there have been some in the past that were so destroyed by hail that you could not possibly see out them. Glad of all the safety improvements they have been able to make. Have a great weekend.

So confused

Um...no because I can read.

No bird strike

They're strong

Not really, it's more about speed than mass

OK I was curious, and I still remember my high school physics, so I did a little research about some things that I needed, and then I did the math. Impact damage is roughly proportional to the kinetic energy dissipated in the impact. Kinetic energy is proportional to half the mass times the velocity squared, commonly written as KE = 0.5 * M * V^2 The hailstones encountered were at most a little larger than golf-ball size (42.67mm). I did some research, and the terminal velocity of a hailstone in meters per second (m/s) is approximately proportional to it's diameter in millimeters (mm) by the formula 1.4 * D^0.8. The aircraft's velocity I had to guess at, but I guessed 225 to 250 knots airspeed (ground-speed is not useful here because both objects in the collision are in the air, and one is in free-fall). In meters per second, that's a range of 116 to 129 m/s. The aircraft was in a descent when it suffered hail damage, but since I don't know the rate of descent I'll simplify the problem by assuming it was in stable level flight at a constant speed. To make the problem much easier to solve, I'll assume there was no wind at the altitude where the collisions occurred. Now to do the math. Since impact damage is roughly proportional to kinetic energy dissipated, we'll assume that all the kinetic energy of the impact was dissipated into causing damage to the radome and that it was an inelastic collision (the colliding objects stuck together after the collision). So to solve the problem all we need to do is find the available kinetic energy of the hailstone, assuming the aircraft is a solid surface approaching at it's velocity of straight and level flight. The terminal velocity of the hailstones encountered is 1.4 * (42.67mm)^0.8 = 28.2 m/s straight down. The velocity of the aircraft was 116 to 129 m/s straight and level. These two velocity vectors are at right angles to each other, so to add them together vectors of these two velocities, I can use the Pythagorean Theroem (A^2+B^2 = C^2, or more usefully for our purposes C = sqrt( A^2 + B^2 )). Plugging in the numbers, we get the following simplifications Starting with C = sqrt( 28.2^2 + (116 to 129)^2 ) C = sqrt(795.24+ (13,456 to 16,641)) C = sqrt(14251.24 to 17436.24) C = 119.38 to 132.04 m/s. Because of the various assumptions I have made, this means that I can consider the aircraft stationary and the hailstone traveling at this speed, and the math would be the same. Now to figure out the mass of the hailstone, as that's the other half of the kinetic energy equation. Mass is density times volume, and the density of regular ice can be treated as a constant for our purposes. Ice has a density of 0.9340 grams per cubic centimeter. I'll assume the hailstone was perfectly spherical, because that means I can use the simple formula for volume of a sphere, which is V(sphere) = 4/3 pi R ^ 3. However, we have a diameter not a radius, so the formula becomes V(sphere) = 4/3 pi (D/2) ^ 3. Since we want our unit to be cubic centimeters, I have to input the hailstone's size as centimeters instead of millimeters, but that simply means moving the decimal point one place to the left. So the hailstone is 4.267 cm in diameter. Put all together, the math to calculate the mass of the hailstone looks like this: M = density(ice)*volume(hailstone) M = 0.9340g/cm^3 * 4/3 pi ((4.267cm)/2) ^3 M = 0.9340g/cm^3 * 40.679cm^3 M = 37.994 grams Now to figure out the thing we came here for in the first place, the total impact kinetic energy. To get Joules output, you need the mass to be in kilograms and the velocity to be in m/s. KE = 0.5 MV^2 KE = (MV^2) / 2 (same thing but in a more useful form) KE = ((0.037994kg) * (119.38 to 132.04 m/s) ^2 )/2 KE = (0.037994* (14,251.24 to 17,436.24))/2 KE = 541.46 to 662.47 Joules. This is the answer we have been seeking. Of course, then you have to multiply that by several hundreds to even a few thousand impacts of that magnitude. I'd say there's more than enough energy there to cave in a radome.

@@44R0Ndin so basically speed kills 😆 you went full out. 👍I can't say I remember much of my math classes lol

They are double pane windows and varry very strong. That radome is very light and damages easily

Radome has to be thin so the radar waves pass through it

Definitely not a bird

On the news said it was a bird strike

They could be spreading false information

It was not

Yeah cause there would be bird remains on the nose of the plane

I was just guessing that too as a total amateur. There's no way hail damages just that specific spot on the plane. If the hail is bad enough to damage the nose, it's bad enough to damage other things. It had to have been a very localized mass that they struck. Like a bird.

Don't trust 50% of what news say. This aircraft went through very intense weather during descent. Weather was crappy over Philly. See the nose and the paint removed as hundreds of hail balls hit it. No blood. Going through hail at 300 knots can be destroying. See pinned comment for similar videos

@@VASAviation Thanks for the clarification. I'm shocked to see hail damage a specific part of the plane so well but nowhere else, but that goes to show what I know about aviation.

@@Mackinstyle the nose cones actually pretty sensitive. it doesn't need to take a huge strike, just enough to cause a dent big enough to start deflecting the air going over it. the pressure alone will eventually make it fail and collapse in on it's self.

I am just speculating but the nose would take the hardest hit since it is flat towards moving direction. Wings too but those might be harder? I wanna see the engine

Hail can do that and more. Just lucky they didn't lose the windshields. Hail damage can write off cars and they aren't flying through it at 250 knots or more.

the nose cone is hollow as the weather radar is behind it. it's not made for things impacting on it.

Radomes are complex structures from composite materials. www.airbus.com/content/dam/corporate-topics/publications/fast/FAST26.pdf edit:typo

Ok so why the other planes Landing without report any damage I mean its JFK the planes there landing one by one so i guess the other planes should report the same thing Next time make a video with weather map

@@ahmedtracker2841 because they went a different way in or the hail dissapated/wasn't present when they passed that. just because they landed JFK doesn't mean it happened in the vicinity.

🙂👍

Yea because I have a better understanding of physics than you
