Airport Meow

Chapter 511
"Where are we now?"

Qiu Weixin checked his computer, "At the junction of Qinghai and Siyi, if we follow the current downward trajectory, the most suitable large airport is Shuangliu Airport!"

Bei Haiyang nodded, Shuangliu Airport is more suitable, the conditions are good in all aspects, and it is backed by the big city of Chengdu, so it can meet all needs.

"It's Shuangliu, contact the ground, and make an emergency landing as required by the state of emergency."

The current condition of DH-555 is not good. The obvious threat is that the No. 3 engine has been punctured, and a piece of the roof has been crushed; I don't know, it can only be known when the aircraft enters the atmosphere and switches to the civil aircraft mode.

There is also an unexpected burden. The big guy over 50 tons is lying on the roof of the DH-555, adding a lot of weight in the air, which will have a considerable impact on the handling of the aircraft.

The feeling of waiting for the boots to hit the ground is not good, and he doesn't know what kind of bad situation he will face in the end, he seems to be used to it.

At 25 kilometers, they started to ignite the engine. As the plane began to enter the instrument flight, countless information poured in, and the real situation of DH-555 began to appear before their eyes.

"Engine No. 1, No. 2 and No. 4 ignited successfully, but the fuel consumption is a bit high. I suspect that there is an oil leak near No. 3 engine."

"Cut off fuel balance, turn off master fuel pump..."

Qiu Weixin was speechless, "You don't need to turn off the fuel master pump, it doesn't start at all!"

Looking at the page after page of error reporting interface on the computer, and listening to the endless alarm above his head, Bei Haiyang sighed,
"How many error reporting options are there?"

Qiu Weixin quickly operated on the computer, page after page, "1... well, 117 items! I guess I can't handle ten items before we run out of fuel!"

This is the collateral effect. Damaged electrical circuits and hydraulic systems will cause numerous control obstacles. Bei Haiyang tried to control the rudder surface, but found that the controllability of the aircraft had dropped to a very dangerous level.

"Weixin, help me calculate the length of the runway needed for landing."

Qiu Weixin immediately began to operate on the onboard computer, and Bei Haiyang's voice came from beside his ear,

"Landing with three engines fully loaded, 50% rudder effect, 70% hydraulic pressure... Use these conditions to calculate."

This is the landing calculation software of the 959 model, to calculate how long the runway needs to be for this large plane to stop.
"Computer analysis will kill us!" Seeing the result, Qiu Weixin turned pale.

There is a key point here, which is the extra tens of tons of weight; the 959 model can stop within 1800 meters even when it is fully loaded, but this refers to the situation where the fuel consumption is similar.

They are now carrying a big dragonfly, like carrying dozens of tons of fuel!The point is that they can't drain the oil yet!
Landing with oil is a big taboo for aircraft landing. There is a possibility of explosion and combustion. The most terrible thing is whether the main landing gear can withstand such a huge impact; even if it is supported, the huge weight will make it difficult for the aircraft to brake, just like a The brake bands of heavy trucks and cars are the same!
"The 3500-meter runway at Shuangliu Airport is too short...but this is the longest of the nearby airports, and we don't have enough fuel to find another place!"

Qiu Weixin entered a total of nine failure factors before he came to such a conclusion. They were dozens of tons heavier than the specified maximum landing weight, and this was the problem.

The heavier the aircraft, the higher the speed and length of the runway required to land.

Qiu Weixin changed several parameters and calculated again, but the result was still not satisfactory.

Bei Haiyang next to him gave a suggestion, "Maybe the big dragonfly is not as heavy as it looks? How much do you think it weighs?"

Qiu Weixin, "70 tons! It is slightly smaller than a human spaceship, which is generally around 90 tons..."

Bei Haiyang came up with a bad idea, "Maybe it's made of foam inside? Anyway, I don't think it's made of steel! Otherwise, it can't be adsorbed on the top of the machine, let's say it's 50 tons!"

Qiu Weixin felt that this was a bit self-deceiving, "Captain, it may indeed be a biological spaceship, but because of this, it means that it is solid, not a steel product, and there is still room inside...well, let's say it is 50 tons."

Qiu Weixin then entered some more optimistic figures, this time the results were different,

"Well, it looks like the situation is not bad, there should be 139 meters left on the runway!"

The 3500-meter runway can only have 139 meters of redundancy. This result is really hard to describe.

Bei Haiyang, "There is almost no room for error? Well, it's better than exceeding 139 meters! That's it!
How fast should we enter the field? "

Qiu Weixin glanced at the computer, "The computer said it was 146 knots..."

Bei Haiyang, "It's definitely not right! That's too slow."

Qiu Weixin was helpless, "You also know about computers..."

Bei Haiyang shook his head, "Don't worry about it! Let's approach at a low speed as much as possible, before the stall alarm goes off."

It is important to maintain the correct speed when landing. Too slow and the plane will lose lift and hit the ground. Too fast and the plane will overshoot the end of the runway and crash.

"Add 20 knots to this speed and we can still stop inside the runway?"

Qiu Weixin worked on the computer again, "Knot 166? Wait a minute...well, the computer says we will stop at 5 meters from the end of the runway."

Bei Haiyang smiled wryly, "Is this good news? Contact the ground!"

Qiu Weixin entered the channel, "Shuangliu tower, this is DH-555, the aircraft is seriously damaged, we need the longest runway, fire trucks, ambulances, construction vehicles, well, it's better to get some more tanks... ..."

Shuangliu Airport, "Understood, the front is clear, runway 12 left, emergency preparedness, huh? You mean tanks? I didn't hear clearly..."

Qiu Weixin repeated, "Yes, it's a tank, or anything like an armored vehicle! We also have an extraterritorial biological spaceship on our plane, weighing more than 50 tons. You can figure it out. Anyway, if it wakes up, we have to Can hold it!"

At Shuangliu Airport, the air traffic controller stuttered, "Wait a minute, we are not prepared for these things, I have to ask the garrison for support!"

Bei Haiyang smiled, "You will scare them!"

Qiu Weixin shrugged, "We've been scared all the way, so we have to find someone to take over?

Captain, when it lands, that dragonfly might be scuttled down, so you have to be prepared! "

Bei Haiyang nodded. He was afraid that this would happen. It would reduce the burden for them to slide down in the air. When the host is under the wheel, it means a disaster.

Therefore, be extremely gentle!
