The fire department was originally going to cover the entire runway with foam, and the original plan was that the foam was enough, but I didn't expect that due to the maintenance problems that had not been used for a long time, it was really a foam car that suddenly put the burden on it, and a few foam cars stopped halfway through the work.

Therefore, it can't be that people's fire brains are not good, only blame Xu Qing for their bad luck.

Xu Qing and they applied for Runway 03, so that the foam can cover part of the middle end and all the stop end, with the help of the foam can greatly reduce the risk of fuel explosion.

The harm is also obvious, too large downwind can easily lead to lift attenuation and altitude plummeting, and at the same time, after further understanding the qi, Xu Qing knew that this downwind was not a stable wind, but a nine-meter gust.

If it is a stable tailwind, the captain adapts to it, and the problem is not particularly big, but the gusts are a little difficult to use.

Increasing gusts of wind downwind is very detrimental to the flat drift and deceleration of the aircraft, and the aircraft is likely to land prematurely.

Not only that, but poor aerodynamic performance due to tailwinds makes it more difficult for the captain to stay in the air with the nose landing gear.

Whether it's grounding too early or not being able to hold the nose gear for a long time, it's the opposite of the purpose of letting the nose gear slow down as much as possible before grounding.

In fact, the foam has covered part of the middle end, and the captain can choose to extend the flat drift distance and appropriately pull the rear grounding point, so that the aircraft can enter the foam area as soon as possible after grounding.

However, you can't be blind and floating!

First, due to the failure of the nose landing gear, the braking performance of the aircraft cannot be fully released, which may lead to longer braking distances.

Second, the tailwind will cause the aircraft to have a faster ground speed, which will also increase the landing distance.

However, some landing gear retract landings will use flap 40 landing, and the effect of this tailwind is not too obvious.

Third, although the foam prevents the danger of fuel explosion, it also changes the braking performance of the runway surface.

No matter how you look at it, the braking effect of the foam-covered pavement will be worse than that of the dry track.

As the braking effect deteriorates, the landing distance naturally increases.

Even if the runway in K City is long enough, it's not a reason for you to do whatever you want!

Notify the tower to change the runway, but fortunately it is too late now, otherwise it is extremely troublesome to arrange a reverse runway for 9831 to divert a large number of aircraft in the approach area.

Because runway 0321 has been covered with foam, it is not suitable for normal flights to land. The airport decided to reactivate runway 0422, which had been closed, and that runway 0422 was used exclusively for flights other than Flight 9831.

Normally, after 2 p.m., after the peak of arrivals, the airport in K City will close a runway and carry out single-runway operation

Another runway happened to be under maintenance, and today for 9831, the maintenance work was hastily completed and reopened.

While waiting, the airport was asked to turn on the navigation equipment and lighting system of runway 03.

In the case of 9831, it is inevitable to evacuate.

The captain communicated with the flight crew and clarified the evacuation order.

If there is an unexpected situation and the cockpit cannot issue an evacuation order, and the cockpit still does not have an evacuation command after the aircraft has stopped for 30 seconds, the purser can command the evacuation by himself.

If the nose landing gear is not completely lowered, it is very easy for the nose to directly rub against the road, so the danger of the cockpit in the nose is actually higher than that of other positions.

The situation in which the cockpit cannot give the evacuation command is objective.

Based on this question, the captain still said to Xu Qing after thinking about it: "Xu Qing, why don't you take the cabin, in case we are here...... If something goes wrong, you might as well stay and command the evacuation! ”

In this kind of pure maneuvering problem, the pilot in the observer position can actually play a role, and there is no need to sit in the cockpit stupidly and take risks.

Xu Qing glanced at the co-pilot and sighed: "Why don't you let Brother Zhou go to the cabin to direct the evacuation, I haven't been flying for long, what experience do you have, isn't it a mess when you go?" ”

The co-pilot's body trembled, and finally gritted his teeth and said: "Xu Qing, I'm not going out, I'm the first co-pilot, I should be here!" ”

The co-pilot's attitude was very firm, without the slightest ambiguous words, and he did not leave himself a little way back.

"Brother, you let me go out and watch, didn't you just look at this purser's new release, I don't have enough experience, I'm afraid that something will go wrong with her? But is my experience enough? It's not just right to let Brother Zhou go out, at least he has been flying for a few more years and can calm down! Xu Qing explained reasonably.

The captain looked at the co-pilot, then at the co-pilot, and sighed in his heart.

Your co-pilot has been flying for a few more years, and he can hold his breath, but can't you see that the shirt on his back is now soaked? Hands shaking? How slow is the response to a question?

Is this a sign of composure?

Although the co-pilot was visibly afraid, he still held on and held on to his post.

As a captain, he is not afraid? I'm afraid of being a flesh-and-blood person. But when you are afraid, you can still fulfill your responsibilities and be a good pilot.

"Zhou, you go out, the cabin will be handed over to you!" The captain made the final decision.

"Brother, how can I get out? I'm the first co-pilot, and I'm out, so isn't that a joke? "The co-pilot is reluctant to go out, and if he goes out, it will be a reputation for escaping.

"Zhou, you are obeying the captain's arrangement, no one can give you anything!" The captain tried his best to help the co-pilot clear the psychological burden, and it was not necessary for all three people to be crammed into the cockpit.

"Captain...... No way! The co-pilot didn't call his brother anymore, but called the captain very officially, and he was unwilling to carry out the captain's orders.

The captain's eyes narrowed, and he also asked in the most formal tone: "You don't know who the top leader on this plane is?" Do you want me to have the security officer fork you out? ”

"Again, can you keep your hands from shaking? How can you help me by staying in the cockpit any longer? I'm not begging you to help me control the lever, don't even turn off the fuel pump then! ”

According to the checklist, the fuel pump needs to be turned off before leveling, this is also to prevent fuel leakage?

The co-pilot clenched his hands, he wanted to stop the trembling of his hands, but he couldn't control it.

At this time, Xu Qing patted the co-pilot's shoulder from behind: "Brother Zhou, I'll come!" ”

Under the captain's combination of soft and hard, the co-pilot still gave up his position.

Xu Qing sat on the right seat, and this familiar position couldn't help but remind him of the shocking event a year ago!

"Are your hands still shaking?" The captain pretended to tease Xu Qing lightly.

The anecdote of Xu Qing's shaking hands has long spread throughout the company.

Xu Qing happened to be wearing a seat belt at the time, and in the face of the captain's ridicule, Xu Qing pursed his lips and sneered at each other: "Then you control it better, don't let me move the lever, I'm ready to turn off the fuel pump!" ”
