CV-16, CV-17 STOBAR carrier thread (001/Liaoning, 002/Shandong)

But the black smoke only appears when you start to accelerate, not when you have reached high speed, right?
And in the photo we see that the plane has left the deck, which means the ship is no longer at low speed.

But acceleration does not happened instantly specially in big ship like AC there is huge drag and inertia! It is not like your car you press the pedal and off you go. The plane can still take off with less than ideal condition

That's exactly the problem, you can't start accelerating when the plane is already on takeoff, but it should be some time before the takeoff operation.

You forgot the second part The plane can take off with less than ideal condition

But we're not talking about whether the aircraft can take off or not.
But precisely because the carrier acceleration process is slow, acceleration should have started before takeoff operations, not waiting until mid-takeoff to start adding fuel to the new boilers.

But it has not reached the optimal condition. And the reg of say 40km/hr has built in safety factor into it. In real war you want to release your jet as fast as possible. You cannot wait until it reach optimal condition! Another thing the wind keep changing all the time

So I said "hard to say"

We have a LOT of picture showing the CVBG cruising in the sea with no smoke!

I'm confused now, what exactly are you trying to say? I just posted a picture of the Liaoning at full speed with no black smoke.

I though you are implying that there must be something wrong with Liaoning spewing smoke

 

[Helius]

There is no necessary connection between whether there is black smoke from the chimney and the speed of the ship, and there is no way to determine the speed of the ship from the photo of the takeoff I mentioned, so I would say it is “hard to say”.

In the photo below of the carrier apparently traveling at high speed, we can't see any black smoke.

Your photo is irrelevant if the ship has already attained cruising speed i.e. turbines have already been ramped up, boilers have already been fired, fuel mix is already optimal, hence no black smoke.

Read mine and others' comments carefully instead of rebutting willy-nilly. The carrier doesn't wait "until mid-takeoff" to fire up boilers. Boilers were already in process of firing up, turbines already in process of revving up, and as they do so the boat picks up speed. Then what happens? Black smoke spews out.

As she picks up speed and once she attains the desired wind speed over deck e.g. 30-40kn, aircraft gets to launch.

So here's an easy explanation, not hard at all - Likely scenario where the boat was already at 20kn but wind speed dropped from 10kn to 5kn, so she needed the extra juice to conduct flight ops. What happens then? Additional boilers are fired up. Here's your black smoke.

And as it happens we pass 30kn and birdie gets to fly. So the air boss says "Go!" without delay. Mind you the boat is still speeding up, as the boilers were still firing up and black smoke getting photographed for this back-and-forth debate. Why? They got the speed, speed is good to go, bird goes. What else they gonna wait for?
